The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without any inventive step, are intended to be within the scope of the present disclosure.

Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.

In the description of the present disclosure, it should be understood that the terms "first", "second", etc. are used to define the components, and are used only for convenience of distinguishing the corresponding components, and if not otherwise stated, the terms have no special meaning, and thus, should not be construed as limiting the scope of the present disclosure.

In the description of the present disclosure, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom" and the like is generally based on the orientation or positional relationship when the koji making machine is normally placed, in which the direction same as the gravity is downward and the direction opposite to the gravity is downward; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself. In addition, unless stated to the contrary, the terms "circumferential" and "radial" generally refer to the circumferential and radial directions of the disk.

In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

Fig. 1-46 exemplarily show the structure of a koji-making machine of the present disclosure. Some of the structures in some of the figures have been simplified or omitted for clarity of illustration.

Referring to fig. 1-46, a koji-making machine 10 includes a disc 1, a discharging mechanism 2, a feeding mechanism 3, a stirring mechanism 4, and a frame 91.

Wherein, disc 1 is used for holding material 20, provides the fermentation place for material 20. The discharging mechanism 2 is used for conveying the brewed or fermented material 20 from the disc 1 to a designated position of a downstream process. The feeding mechanism 3 is used for feeding the material 20 to be fermented into the disc 1. The stirring mechanism 4 is used for stirring the materials 20 on the disc 1 in the fermentation process so as to ensure that the fermentation is more uniform and sufficient. The frame 91 serves to provide support for the puck 1.

The disk 1 is mounted on the frame 91 and supported by the frame 91. The discharging mechanism 2, the feeding mechanism 3 and the material turning mechanism 4 are arranged above the disc 1 and can be arranged in a relative rotation manner with the disc 1, so that the discharging, feeding and material turning of the disc 1 in the whole circumferential direction can be realized by utilizing the relative rotation between the discharging mechanism 2, the feeding mechanism 3 and the material turning mechanism 4 and the disc 1. In order to realize the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the disc 1, the disc 1 can be rotated, but the discharging mechanism 2, the feeding mechanism 3 and the material turning mechanism 4 do not rotate, or the discharging mechanism 2, the feeding mechanism 3 and the material turning mechanism 4 can be rotated, but the disc 1 does not rotate. Here, the rotation of the disc 1, the discharging mechanism 2, the feeding mechanism 3 and the stirring mechanism 4 refers to the rotation around the longitudinal geometric center line of the disc 1. The longitudinal geometric centre line of the disk 1 is subsequently also referred to as the longitudinal axis of rotation.

Referring to fig. 1-2, in the embodiment of the present disclosure, a disc 1 includes a disc body 11, an inner ring 12, and an outer ring 13. The inner ring 12 and the outer ring 13 are respectively arranged on the inner ring and the outer ring of the disc body 11, and both extend upwards from the disc body 11 to form the inner wall and the outer wall of the disc 1, so that the disc 1 is in a ring groove shape integrally.

Compared with the disc 1 which is not in the shape of the ring groove in the related technology, the disc 1 in the shape of the ring groove has wider application range, because the disc 1 in the shape of the ring groove not only can be used for fermenting solid materials, but also can be used for fermenting liquid or solid-liquid mixed materials, and provides an equipment foundation for fermenting liquid-containing materials. When the disc 1 is in the shape of a ring groove, the outer ring 13 and the inner ring 12 can block the material 20 and prevent the material 20 from falling off from the outer edge or the inner edge of the disc body 11, and particularly, when the material 20 contains liquid, the outer ring 13 and the inner ring 12 can prevent the material 20 from flowing to the outside of the disc body 11 from the radial inner side and the radial outer side, so that the fermentation and brewing of the material 20, particularly the material 20 containing liquid can be more conveniently realized.

However, the ring-shaped disc 1 has a problem of difficulty in discharging. Disc 1 that is not the annular groove shape can conveniently follow the radial one side ejection of compact of disc 1, for example, to disc 1 that does not contain outer loop 13, generally adopt the ejection of compact mode (can be called outer lane ejection of compact mode) of the ejection of compact from the radial outside, promptly, discharge mechanism 2 can accomplish the fermentation back at the material, carry the material towards the radial outside of disc 1, follow the radial outside ejection of compact of disc 1, because the outer loop 13 is not set up in the disk body 11 outer lane, consequently, under discharge mechanism 2's effect, material 20 can directly drop from disk body 11 outer fringe, realize the outer lane ejection of compact. However, for the circular disc 1 in the shape of the circular groove, since the outer edge and the inner edge of the disc body 11 are respectively provided with the outer ring 13 and the inner ring 12, the outer ring 13 and the inner ring 12 can block the discharge of the material 20, and therefore, it is difficult to directly discharge the material from one radial side of the disc body 11 by using the discharge mechanism 2, for example, it is difficult to directly discharge the material from the radial outer side due to the blocking of the outer ring 13, and it is also difficult to directly discharge the material from the radial inner side due to the blocking of the inner ring 12, for example.

Therefore, the discharging problem is an important problem restricting the development of the ring groove type disc type koji making machine and needs to be solved urgently.

In view of the above, referring to fig. 2 to 4, in the embodiment of the present disclosure, the center of the tray 11 is provided with the discharge hole 14, and the inner ring 12 and the tray 11 are no longer of an integral structure but are changed into a split structure, and are detachably combined, and meanwhile, the koji making machine 10 includes an inner ring driving mechanism 62, and the inner ring driving mechanism 62 is in driving connection with the inner ring 12 and drives the inner ring 12 to move so as to control the inner ring 12 to be separated from or combined with the tray 11.

Because the inner ring 12 can be separated from or combined with the disc body 11 under the driving of the inner ring driving mechanism 62, when the inner ring 12 is separated from the disc body 11, the inner ring 12 can no longer block the material 10 on the disc 1 from flowing to the discharge hole 12 at the center of the disc body 11, and therefore, the material 20 can conveniently flow to the discharge hole 12 for discharging.

Therefore, the inner ring 12 is arranged to be separable from the tray body 11, and the inner ring 12 is controlled to be separated from the tray body 11, so that the difficult problem of discharging of the ring-shaped disc 1 can be solved skillfully, and the koji making machine 10 can discharge materials conveniently.

Moreover, when the material is not required to be discharged, the inner ring 12 can still be combined with the disc body 11 to block the material 20 and prevent the material 20 from falling or leaking, so that the inner ring 12 and the inner ring driving mechanism 62 can meet the material leakage prevention and falling requirements of the disc 1 before the fermentation is finished and can also meet the discharging requirements after the fermentation is finished.

Therefore, by controlling the separation or combination of the inner ring 12 and the disc body 11, the disc 1 can meet the requirements of material leakage prevention and falling prevention before fermentation is completed, and can also meet the requirement of discharging after fermentation is completed, the difficult problem of discharging of the annular groove-shaped disc 1 is solved ingeniously, and the annular groove-shaped disc 1 can also be discharged conveniently.

In addition, the mode of discharging is realized by controlling the separation of the inner ring 12 and the disc body 11, no special requirement is made on whether the disc 1 rotates, the disc discharging device can be applied to the condition that the disc 1 rotates and the condition that the disc 1 does not rotate, and the application range is wide.

In addition, the mode of discharging is realized by controlling the separation of the inner ring 12 and the disc body 11, the structure of the discharging mechanism 2 is not required to be improved, the discharging process can be smoothly completed, even the discharging mechanism 2 can be omitted, and particularly, the discharging mechanism 2 can be omitted for certain materials 20 with good flowing state after fermentation is completed. Since the material 20 having a better flow state can flow to the discharge port 14 by itself without being conveyed by the discharge mechanism 2 when the inner ring 12 is separated from the tray body 11, in this case, the discharge process can be realized without providing the discharge mechanism 2, so that the entire structure of the koji making machine 10 can be simplified.

2-4, in some embodiments, inner ring drive mechanism 62 includes a lift drive mechanism 621, and lift drive mechanism 621 is drivingly connected to inner ring 12 and controls the separation or engagement of inner ring 12 from disc 11 by driving inner ring 12 up and down. In this case, the inner ring driving mechanism 62 may control the inner ring 12 to be separated from or combined with the disc 11 by driving the inner ring 12 to move up and down, so as to control whether to discharge.

As shown in fig. 2-4, the inner ring 12 is movable between a lower limit position and an upper limit position by the elevating drive mechanism 621. Wherein the inner ring 12 is in the lower extreme position as shown in fig. 2 in solid line and fig. 3; the inner ring 12 is in the upper extreme position as shown in phantom in fig. 2 and in fig. 4.

As shown in fig. 2-3, when the inner ring 12 is at the lower limit position, the inner ring 12 is combined with the disc body 11, the disc 1 is in the shape of a ring groove, and the inner ring 12, the disc body 11 and the outer ring 13 together form a ring-shaped container for containing the material 20, so that the material 20 can be normally limited by the disc body 11, the outer ring 13 and the inner ring 12 without falling or leaking. In this state, the inner ring 12 encloses the discharge hole 14 at the center of the tray body 11 to separate the material 20 on the tray body 11 from the discharge hole 14 at the center of the tray body 11, so that the material 20 cannot flow to the discharge hole 14, i.e., cannot be discharged. This state is therefore suitable for processes before discharge, for example for fermentation processes, and also for feed processes before the start of fermentation. In order to improve the sealing performance between the tray body 11 and the inner ring 12 at the lower limit position, referring to fig. 3-4, in some embodiments, a sealing member 16 is disposed between the inner ring 12 and the tray body 11, so that when the inner ring 12 is combined with the tray body 11, the sealing performance is better, the material 20 can be more effectively prevented from falling from the inner ring 12 side, and especially, the leakage at the inner ring 12 can be more effectively prevented, so that the disc 1 is particularly suitable for the brewing or fermentation process of the liquid or solid-liquid mixed material. Illustratively, as shown in FIG. 4, the seal 16 is disposed on the inner ring 12 and is raised and lowered with the inner ring 12, which further facilitates the inner ring 12 maintaining a good seal with the disc 11 after being lowered into position.

As can be seen from fig. 2 and 4, when the inner ring 12 is at the upper limit position, the inner ring 12 rises to a position above the tray body 11 and is separated from the tray body 11, at this time, the inner ring 12 does not block the material 20, but the central area of the tray body 11 originally surrounded by the inner ring 12 is completely open and is not blocked by the inner ring 12, so that the space between the lower end of the inner ring 12 and the tray body 11 provides a condition for discharging the material 20, and the discharge hole 14 at the center of the tray body 11 is communicated with the space from the inner ring to the outer ring of the tray body 11, so that the material 20 can flow to the discharge hole 14, and central discharge is realized. Therefore, this state is suitable for the discharging process.

It can be seen that the inner ring 12 is lifted relative to the disc body 11, so that the disc 1 can meet the requirements of material leakage prevention and dropping prevention before fermentation is completed and the requirement of discharging after fermentation is completed, the difficult problem of discharging of the annular groove-shaped disc 1 is solved ingeniously, and the annular groove-shaped disc 1 can also be discharged conveniently.

In addition, the mode of discharging is realized by lifting the inner ring 12, no special requirement is made on whether the disc 1 rotates, the disc discharging device can be applied to the condition that the disc 1 rotates and the condition that the disc 1 does not rotate, and the application range is wide.

Meanwhile, the inner ring 12 is lifted relative to the disc body 11, the realized discharging mode is a central discharging mode, and compared with an outer ring discharging mode for discharging from the radial outer side, the discharging mode is simpler and more convenient. Because the diameter of the outer ring of the disc body 11 is much larger than that of the inner ring, and the size and the weight of the outer ring 13 are much larger than those of the inner ring 12, the difficulty of discharging the outer ring is high.

Particularly, if the outer ring discharging mode is realized by adopting the mode of lifting the outer ring 13, the lifting difficulty is higher because the diameter of the outer ring 13 is larger and the weight is heavier, the requirement on a lifting mechanism for driving the outer ring 13 to lift is higher, the potential safety hazard in the lifting process is larger, and the realization difficulty is larger.

If the outer ring 13 is not lifted, but the outer ring 13 is directly provided with the discharge door to discharge, the requirement on whether the disc 1 rotates is high, and the difficulty in realizing is high when the disc 1 rotates, because the discharge door on the outer ring 13 rotates along with the disc 1, but because the discharge mechanism 2 does not rotate at the moment, the discharge mechanism 2 is difficult to align with the discharge door, how to utilize the non-rotating discharge mechanism 2 to send the materials on the whole disc 1 to the rotating discharge door can become a difficult problem, resulting in difficult discharge, and in addition, even if the discharge mechanism 2 and the discharge door can be aligned all the time, the materials can be discharged from the whole circumference of the outer ring due to the rotation of the discharge door, so the receiving of the materials can become a difficult problem, it may be necessary to arrange a receiving device around the entire circumference of the outer ring 13 below the outer ring to receive material 20 falling from the entire circumference, but this is costly and takes up a lot of space. And if when disc 1 does not rotate, realize the outer lane ejection of compact through the mode that sets up the discharge door on outer loop 13, then in order to realize the ejection of compact of material on whole disc 1 this moment, need discharge mechanism 2 rotatory, but discharge mechanism 2 is rotatory, disc 1 does not rotate, just means that can't align all the time between discharge mechanism 2 and the discharge door, how so utilize pivoted discharge mechanism 2, come the material on the whole disc 1, all send motionless discharge door department to, also is a difficult problem.

Therefore, the difficulty is high for the circular groove-shaped disc 1 by adopting an outer ring discharging mode. The outer ring discharging method is mostly adopted in the related art, mainly because the disc 1 in the related art does not have the outer ring 13.

In the invention, the mode of lifting the inner ring 12 is adopted to realize the central discharging mode of the annular groove-shaped disc 1, so that various problems faced by the outer ring discharging mode can be ingeniously avoided.

On the one hand, the diameter of inner ring 12 is less, and weight is lighter, and consequently, it is convenient to go up and down, and is relatively lower to the requirement that is used for driving inner ring actuating mechanism 62 that inner ring 12 goes up and down, only needs to have the inner ring actuating mechanism 62 of less lifting capacity, can satisfy the lift demand of inner ring 12, and because inner ring 12 diameter is less, weight is lighter, so, inner ring 12 realizes steady lift process more easily, and the lift process is safe steady more.

On the other hand, the inner ring 12 is lifted, the discharging can be realized only by arranging the discharging hole 14 in the center of the disc body 11, the requirement on whether the disc 1 rotates is low, and the material receiving is convenient. In this case, if the disc 1 rotates, since the inner ring 12 has a small diameter, the material 20 falling from the discharge port 14 can be easily received, and for example, when a receiving device such as a receiving tray is provided below the discharge port 14 to receive the material, the receiving device only needs to have a small diameter, so that the cost is low and the floor space is small. If the disk 1 does not rotate, the inner ring 12 is lifted, so that the blocking of the inner ring 12 to the whole inner ring circumference can be thoroughly eliminated, and therefore, the rotary discharging mechanism 2 can be conveniently abutted to the non-rotary discharging port 14, so that the material 20 can be conveniently conveyed to the discharging port 14 no matter which circumferential position the discharging mechanism 2 rotates to, and discharging is carried out, namely, the problem that the discharging mechanism 2 is difficult to abut to the discharging port 14 does not exist at the moment.

It can be seen that the central discharging mode of the annular groove-shaped disc 1 is realized by adopting the mode of lifting the inner ring 12, and the discharging of the annular groove-shaped disc 1 can be conveniently realized based on a simpler structure and lower cost.

And, the inner ring 12 carries out the central ejection of compact after rising, owing to can thoroughly remove the effect of blockking of inner ring 12, consequently, be favorable to improving ejection of compact sufficiency for the ejection of compact is clean thorough more, reduces ejection of compact and remains.

In order to facilitate the transportation of the material 20 falling from the discharge port 14 to the downstream process, referring to fig. 2, in some embodiments, the koji making machine 10 includes a discharging mechanism 63, and the discharging mechanism 63 is disposed below the discharge port 14 and communicates with the discharge port 14 to transport the material 20 falling from the discharge port 14 to the radial outside of the disc 1. The discharging mechanism 63 may be one or a combination of screw type, scraper type or belt type conveying mechanism.

Based on the arranged material discharging mechanism 63, after the material 20 falls down from the material outlet 14, the material can directly fall onto the material discharging mechanism 63 and is conveyed to the designated position of the downstream process by the material discharging mechanism 63, the method is simple and convenient, the connection between the processes is tighter, and the improvement of the production efficiency is facilitated. At this time, a special receiving device such as a receiving tray is not needed to be additionally arranged below the discharge port 14, so that the structure is simple, and the problem of the occupied area of the receiving device such as the receiving tray is not needed to be considered.

In addition, referring to fig. 2 and 5, in some embodiments, the koji making machine 10 includes a spraying device 25, and the spraying device 25 is used for spraying liquid to the material 20 on the disc 1 and/or the discharging mechanism 2.

The spraying device 25 is used for spraying liquid to the materials 20 on the disc 1, so that the fermentation brewing requirements and the conveying requirements of the materials can be met conveniently when needed, for example, in the fermentation and brewing processes of some materials 20, water or other liquid needs to be added for good fermentation, and therefore, the spraying device 25 is used for spraying liquid to the materials 20 on the disc 1, so that the technological requirements of the fermentation brewing of the materials 20 can be met well; for another example, some materials 20 are limited by their characteristics, and are difficult to transport if not diluted, so that the spraying device 25 can be used to spray liquid on the materials 20 on the disc 1 to better meet the transportation requirements of the materials 20, and the materials 20 can be diluted to facilitate the transportation of the materials, for example, the discharging of the materials 20 can be facilitated.

Utilize sprinkler 25 to spray liquid to discharge mechanism 2, can realize the washing to discharge mechanism 2, be favorable to keeping discharge mechanism 2 clean.

It can be seen that, due to the provision of the spraying device 25, the requirements of the fermentation and brewing process, the material conveying process and the device cleaning process can be better met by spraying the material 20 and/or the discharge means 2 with liquid.

Wherein, sprinkler 25 can set up on discharge mechanism 2, like this, sprinkler 25 both can conveniently spray liquid to discharge mechanism 2 when discharge mechanism 2 needs to wash, also can conveniently spray liquid to material 20 in the fermentation brewing process or ejection of compact in-process.

In addition, in the related art, only the direct ventilation mode is usually adopted to adjust the temperature of the material 20 in the fermentation and brewing process, the temperature adjusting mode is single, the temperature adjusting effect is to be improved, and the overall fermentation and brewing effect is affected. Aiming at the situation, the temperature adjusting mode of the material 20 is improved, so that the temperature adjusting mode is not limited to direct ventilation and heat exchange, but an indirect heat exchange mode can be adopted to adjust the temperature of the material.

As one of the indirect heat exchange tempering means, referring to fig. 17, in some embodiments, the koji making machine 10 includes a tempering device 5, the tempering device 5 includes a heat exchanger 51, and the heat exchanger 51 is rotatably disposed with respect to the disc 1 and extends into the material 20 on the disc 1.

The heat exchanger 51 is a heat exchanger with a heat exchange medium (for example, water and other liquid) flowing inside, so that the heat exchanger extends into the material 20, heat exchange between the material 20 and the heat exchange medium can be realized, the temperature of the material 20 can be adjusted, and the temperature requirement of the fermentation brewing process can be met.

Moreover, the heat exchanger 51 and the disc 1 are arranged in a relatively rotatable manner, so that the heat exchanger 51 can regulate the temperature of the materials 20 on the disc 1 at different circumferential positions, and the requirement of regulating the temperature of the materials 20 on the whole disc 1 is met. Meanwhile, relative rotation between the heat exchanger 51 and the disc 1 also enables relative movement between the heat exchanger 51 and the material 20, so that the heat exchanger 51 can play a certain role in stirring the material 20, and the heat exchanger 51 can have a temperature adjusting function and a material stirring function.

Therefore, based on the heat exchanger 51, the temperature adjusting device 5 can realize an indirect heat exchange mode, and enrich the temperature adjusting mode of the koji making machine 10, so that the koji making machine 10 is not limited to the direct ventilation heat exchange temperature adjusting mode. And, based on heat exchanger 51 that sets up, attemperator 5 not only can be to the material accuse temperature, can also be to the material stirring, and a tractor serves two-purpose, and the function is abundant.

The temperature adjusting device 5 can realize the stirring function only by means of relative movement with the disc 1, and under the condition, the stirring intensity of the temperature adjusting device 5 is lower than that of a conventional stirring mechanism 4 which revolves relative to the disc 1 and rotates around the axis of the temperature adjusting device, so that the temperature adjusting device is particularly suitable for materials 20 which are not suitable for violent stirring. In the fermentation and brewing process of some materials 20, if the materials are stirred violently, the fermentation and brewing effect can be influenced, and under the condition, the temperature adjusting device 5 can be utilized to realize the stirring function, so that the requirement of the materials 20 on the stirring process with lower strength is met.

Under the condition that the koji making machine 10 simultaneously comprises the temperature adjusting device 5 and the material turning mechanism 4, the temperature adjusting device 5 can meet more various material turning requirements together with the material turning mechanism 4, and the working flexibility of the koji making machine 10 is enhanced. For example, in the case of severe stirring of the material 20, the stirring mechanism 4 may be started, or the temperature adjusting device 5 and the stirring mechanism 4 may be used to stir together, whereas in the case of non-severe stirring of the material 20, the temperature adjusting device 5 may be used to stir only, and the stirring mechanism 4 is not started any more.

As another way of indirect heat exchange and temperature adjustment, referring to fig. 32-33 and 45, in some embodiments, a chamber 15 is provided inside the disc 1, and the koji making machine 10 includes a first heat exchange system 81, the first heat exchange system 81 is communicated with the chamber 15, and a heat exchange fluid is introduced into the chamber 15, so as to adjust the temperature of the material 20 by heat exchange between the heat exchange fluid and the material 20 on the disc 1.

In the above arrangement, the disc 1 is not a solid disc, but has a hollow interlayer, and a heat exchange fluid can be introduced into the interlayer from the first heat exchange system 81, and the temperature of the material 20 can be controlled by the heat exchange between the heat exchange fluid and the material 20. The first heat exchange system 81 may be referred to as a sandwich heat exchange system. The heat exchange fluid introduced into the interlayer can be liquid such as water and the like so as to exchange heat with the material 20 better and realize better temperature control effect.

Therefore, based on the arranged first heat exchange system 81, an indirect heat exchange temperature regulation mode based on heat exchange between a heat exchange medium and the material 20 can be realized, and the temperature regulation mode of the starter propagation machine 10 is enriched, so that the starter propagation machine 10 is not limited to a direct ventilation temperature regulation mode.

In the above arrangement, the chamber 15 may be located inside at least one of the body 11, the outer ring 13 and the inner ring 12 of the disc 1, so that the disc 1 is in whole or in part of a sandwich-type structure. The portions of the chamber 15 located within the disc 11, outer ring 13 and inner ring 12 may be referred to as a first chamber 151, a second chamber 152 and a third chamber (not shown) respectively for ease of distinction.

For example, referring to fig. 32-33, in some embodiments, the chamber 15 includes a first chamber 151 disposed within the tray 11, in which case the tray 11 is a sandwich-type structure. Because material 20 mainly piles up on disk body 11, consequently, set up disk body 11 into sandwich structure to let in heat transfer fluid in the intermediate layer of disk body 11, can satisfy the heat transfer demand of most of material 20, realize better thermoregulation effect. Referring to fig. 34 and 46, the interior of the first chamber 151 in the tray body 11 may be divided into at least two heat exchange chambers 153, each heat exchange chamber 153 has an inlet 157 and an outlet 158 formed on a bottom wall thereof, and the inlet 157 and the outlet 158 respectively allow the heat exchange fluid to flow into and out of the first chamber 151. Different heat exchange cavities 153 are arranged in the tray body 11, so that the heat exchange of the tray body 11 in different areas can be realized, and because each area can independently exchange heat, the fault of a certain area does not influence the heat exchange of other areas, the reliability is high, and the maintenance is convenient. This type of heat exchange of the sub-zones of the plate body 11 is suitable for both the case where the disc 1 rotates (see fig. 34 to 37) and the case where the disc 1 does not rotate (see fig. 46). The heat exchange cavities 153 may be sequentially arranged along the circumferential direction of the disc 1, and are distributed over the entire circumference of the disc body 11, so as to realize heat exchange of the materials 20 on the entire circumference of the disc body 11.

For another example, returning to FIGS. 32-33, in some embodiments, the chamber 15 includes a second chamber 152 disposed within the outer ring 13, in which case the outer ring 13 is a sandwich-type structure. The heat exchange fluid in the interlayer of the outer ring 13 can conveniently exchange heat with the materials 20 at different heights (or called thicknesses), so that a good temperature regulation effect is realized.

For another example, with continued reference to FIGS. 32-33, in some embodiments, the chamber 15 includes both the first chamber 151 and the second chamber 152, in which case the disc 11 and the outer ring 13 are of a sandwich-type construction. Under the condition, the heat exchange fluid in the disc body 11 can be utilized to exchange heat with the material 20, and the heat exchange fluid in the outer ring 13 can be utilized to exchange heat with the material 20, so that the bottom and the side of the material 20 can exchange heat with the heat exchange fluid, and therefore, the temperature of the material 20 is prevented from being uneven in the circumferential direction or the height direction, and a more uniform temperature adjusting effect is achieved.

In the case where the chamber 15 includes both the first chamber 151 and the second chamber 152, the second chamber 152 may communicate with the first chamber 151, and the heat exchange fluid provided by the first heat exchange system 81 may flow from the first chamber 151 to the second chamber 152 and flow out of the second chamber 152 to the outside of the disk 1. Like this, heat transfer fluid can be in disk body 11 with material 20 abundant heat transfer back, flow to outer loop 13 in again, with material 20 heat transfer, this kind of heat transfer mode of disk body 11 back outer loop 13 earlier more accords with the characteristics that material 20 tiling area is great, and thickness is less, disk body 11 department heat transfer demand is bigger, is favorable to realizing better heat transfer effect to, this kind of heat transfer mode of disk body 11 back outer loop 13 earlier also makes things convenient for first heat transfer system 81 to arrange. The first heat exchange system 81 can be arranged below the disc body 11, and the space below the disc body 11 is large, so that the arrangement is convenient, and particularly the arrangement of the first heat exchange system 81 is convenient when the disc 1 rotates.

When the disc 1 rotates, the problem is how to arrange the first heat exchange system 81 to avoid the winding of the pipeline in the rotation process of the disc 1.

In order to solve the problem of the winding of the pipes of the first heat exchange system 81 on the rotation of the disc 1, referring to fig. 32-34, in some embodiments, when the disc 1 is rotatably disposed, the chamber 15 includes the first cavity 151 disposed inside the disc body 11, and the first heat exchange system 81 includes a first shell 811 and a second shell 812. The first housing 811 is disposed on the tray body 11 and rotates together with the tray body 11. The second housing 812 is connected below the first housing 811 and is rotatably disposed with respect to the first housing 811. The first housing 811 is provided with an inlet ring groove 813 and an outlet ring groove 814 which are spaced apart from each other. The second housing 812 is provided with an inlet 818 and an outlet 819 which are spaced apart from each other. The inlet opening 818 communicates with the first chamber 151 through the inlet ring groove 813. The discharge port 819 communicates with the first chamber 151 through a discharge ring groove 814. The inlet 818 is connected to an inlet pipe 81a which communicates with a heat exchange fluid supply source. A discharge pipe 81b is connected to the discharge port 819 for discharging the heat exchange fluid.

With the above arrangement, the heat exchange fluid enters the first chamber 151 through the inlet opening 818 and the inlet ring groove 813, and flows out of the outlet ring groove 814 and the outlet opening 819 to the outside after passing through the disk 1. In the whole process, the first shell 811 provided with the inlet ring groove 813 and the outlet ring groove 814 rotates along with the disc body 11, and the second shell 812 connected with the inlet pipe 81a and the outlet pipe 81b does not rotate along with the disc body 11, so that the flow of the heat exchange fluid is not influenced by the rotation of the disc 1, no matter which angle the disc 1 rotates, the inlet pipe 81a and the outlet pipe 81b can be in the original position and do not rotate along with the disc, and meanwhile, the heat exchange fluid can enter and exit the first cavity 151 through the inlet ring groove 813 and the outlet ring groove 814, and interlayer heat exchange is realized. It can be seen that the above arrangement can satisfy the supply requirement of the heat exchange fluid for the whole rotating disk 1 while effectively avoiding the winding of the inlet pipe 81a and the outlet pipe 81 b.

Since the space at the lower portion of the tray body 11 is large and substantially free from obstruction, the first and second housings 811 and 812 and the inlet and outlet pipes 81a and 81b may be conveniently arranged, thereby conveniently achieving the arrangement and installation of the first heat exchange system 81.

Referring to fig. 33, in some embodiments, the inlet ring groove 813 is located on the radial inner side of the outlet ring groove 814, so that the layout is more compact and reasonable, and the heat exchange fluid flows to the radial inner side and then to the radial outer side after entering the first cavity 151, thereby orderly realizing the temperature adjustment of the material 20 at various positions of the whole disc body 11.

In order to guide the heat exchange fluid to flow orderly in the plate body 11, referring to fig. 33-35, in some embodiments, a first partition plate 154 and a second partition plate 155 are arranged in the first cavity 151, the first partition plate 154 extends along the radial direction of the disk 1 and is spaced from the inner ring 12, the second partition plate 155 is arranged on one side of the first partition plate 154 along the circumferential direction of the disk 1 and partitions the space of the first cavity 151 on one side of the first partition plate 154 along the circumferential direction of the disk 1, an inlet 157 and an outlet 158 are arranged on the bottom wall of the first cavity 151, the inlet 157 and the outlet 158 are respectively communicated with the inlet ring groove 813 and the outlet ring groove 814, and the inlet 157 and the inlet ring groove 813 and the outlet 158 and the outlet ring groove 814 are arranged on the opposite sides of the second partition plate 155 along the radial direction of the disk 1.

Based on the above arrangement, the heat exchange fluid entering the first chamber 151 can sequentially flow through different positions of the tray body 11 in the radial direction, and finally flow through the whole tray body 11 to perform sufficient heat exchange with the material 20 on the tray body 11.

The flow process of the heat exchange fluid based on the above arrangement will be described here by taking as an example a case where the inlet ring groove 813 is located radially inside the discharge ring groove 814.

Referring to fig. 34 to 37, when the inlet ring groove 813 is located radially inside the outlet ring groove 814, the heat exchange fluid flowing into the inlet ring groove 813 can enter the first chamber 151 through the inlet 157, the heat exchange fluid entering the first chamber 151 can flow only in the space of the first chamber 151 located on one side of the first partition 154 in the circumferential direction of the disk 1 (the space on the side where the inlet 157 is located, which is denoted as the first space 15a in fig. 35) due to the blockage by the first partition 154, and the heat exchange fluid cannot flow toward the radially outer side of the disk 1 but can flow only toward the radially inner side of the disk 1 due to the blockage by the second partition 155, and when flowing to the position near the inner ring 12, flows into the space of the first chamber 151 located on the other side of the first partition 154 in the circumferential direction of the disk 1 (the space on the other side where the inlet 157 is not located, designated as the second space 15b in fig. 35), then turns back, flows radially outward of the disk 1, and finally flows toward the outlet 158, and flows out to the outside of the disk body 11 via the outlet 158. The heat exchange fluid flowing out of the disc body 11, as shown in fig. 33, flows through the discharge ring groove 814, the discharge port 819 and the discharge pipe 81b in sequence, and flows back to the heat exchange fluid supply source to realize the circulation flow of the heat exchange fluid.

In the case of the second chamber 152 provided in the outer ring 13, when the heat exchange fluid flowing from the radial inner side to the radial outer side of the disk body 11 flows to the vicinity of the outer ring 13, as shown in fig. 34 to 35, the heat exchange fluid flows into the second chamber 152 from the inflow port I of the second chamber 152, flows through the second chamber 152, flows back to the first chamber 151 from the outflow port O of the second chamber 152, flows toward the radial inner side until flowing to the outlet 158, and flows out of the disk body 11 from the outlet 158. At this time, there is no space between the first diaphragm 154 and the outer ring 13, and the two contact each other, so that the fluid flowing to the outer ring 13 is prevented from flowing toward the second chamber 152 but directly toward the outlet 158.

In the case where the second chamber 152 is not provided in the outer ring 13, when the heat exchange fluid flowing from the radial inside to the radial outside of the disk body 11 flows to the vicinity of the outer ring 13, as shown in fig. 35 to 36, the heat exchange fluid does not flow to the second chamber 152, but directly flows through the space between the first partition 154 and the outer ring 13, turns back, flows toward the radial inside until it flows to the outlet 158, and flows out of the disk body 11 from the outlet 158. That is, in this case, a space is provided between the first partition 154 and the outer ring 13.

It can be seen that, when the inlet ring groove 813 is located on the radial inner side of the outlet ring groove 814, based on the first partition plate 154 and the second partition plate 155, the heat exchange fluid can be guided to flow in the order of first toward the radial inner side, then toward the radial outer side, and then toward the radial inner side, so that the heat exchange fluid can orderly flow through each radial position of the disc body 11 to exchange heat with each radial material 20, and in addition, under the condition that the second cavity 152 is arranged in the outer ring 13, the heat exchange fluid can more conveniently flow from the first cavity 151 to the second cavity 152, thereby facilitating the flow heat exchange process of the disc body 11 and then the outer ring 13.

In each of the above embodiments, to improve the heat exchange effect of the sandwich, referring to fig. 32-33, in some embodiments, baffles 156 are provided within the chamber 15 to direct the flow of heat exchange fluid into the chamber 15. As shown in fig. 33, a plurality of baffles 156 may be arranged side by side, and two adjacent baffles 156 may be arranged on two opposite side walls of the chamber 15 and partially staggered in the opposite direction of the two side walls to form baffling flow channels for guiding the heat exchange fluid to flow in the chamber 15 in a baffling manner. For example, referring to fig. 33, in some embodiments, a plurality of sets of baffles 156 may be disposed in the first cavity 151 inside the tray body 11, each set of baffles 156 is provided with a plurality of baffles 156 disposed at the same circumferential position, the baffles 156 disposed at the same circumferential position are arranged side by side along the radial direction of the disk 1, and two adjacent baffles 156 are respectively connected to the upper and lower sidewalls of the first cavity 151 and are arranged in a staggered manner in the up-and-down direction to form an S-shaped baffle flow channel. The baffling flow can prolong the flowing time of the heat exchange fluid in the chamber 15, so that the heat exchange fluid can exchange heat with the material 20 more fully, and the temperature control effect on the material 20 is improved.

In addition, referring to fig. 38, as another indirect heat exchange temperature adjustment manner, in some embodiments, the starter propagation machine 10 includes a second heat exchange system 82, the second heat exchange system 82 includes a reservoir 821, the reservoir 821 is disposed below the disc 1 and is used for containing liquid, and the disc 1 is at least partially immersed in the liquid in the reservoir 821. So, can realize soaking formula heat transfer process, utilize the liquid in the liquid storage tank 821 and the heat transfer between material 20 on the disc 1, realize the temperature regulation to material 20. The indirect heat exchange temperature regulation mode is simple and easy to implement, and can be conveniently applied no matter whether the disc 1 rotates or not.

The embodiments shown in fig. 1-46 are further described below.

First, a first embodiment shown in fig. 1-35 will be described.

Referring to fig. 1-2, in this first embodiment, a koji making machine 10 includes a disc 1, a discharging mechanism 2, a feeding mechanism 3, a stirring mechanism 4, a temperature adjusting device 5, a turntable mechanism 61, a ventilation device 7, a first heat exchange system 81, and a frame 91.

Wherein, the disc 1 is rotatably arranged on the frame 91 and is internally provided with the material 20 to be fermented and brewed. The discharging mechanism 2 is used for conveying the brewed or fermented material 20 from the disc 1 to the designated position of the next process. The feed mechanism 3 is used to feed the material 20 to be fermented or brewed into the disc 1. The stirring mechanism 4 is used for stirring the materials 20 on the disc 1. The temperature adjusting device 5 is used for controlling temperature and turning the material 20 on the disc 1. The turntable mechanism 61 is used for driving the disc 1 to rotate. The ventilating device 7 is used for ventilating the koji making chamber 78 in which the disc 1 is located, and the temperature of the material 20 is controlled by penetrating the material 20 with cold and hot air. The first heat exchange system 81 is used for introducing heat exchange fluid into the interlayer of the disc 1 to realize indirect heat exchange temperature control of the material 20.

In summary, the starter propagation machine 10 of this embodiment is an assembly of a device which feeds a material 20 into a disc 1 through a feeding mechanism 3, controls the material brewing or fermentation process through one or more of a material turning mechanism 4, a temperature adjusting device 5, a ventilating device 7 and a first heat exchange system 81 during the rotation of the disc 1, and finally conveys the fermented or brewed material 20 to the next process through a discharging mechanism 2.

The respective components will be described below.

Fig. 1-2 show the structure of the disc 1 in this embodiment. As shown in fig. 1-2, in this embodiment, the disc 1 is an annular groove-shaped disc including a disc body 11, an inner ring 12, and an outer ring 13. The center of the tray body 11 is provided with a discharge hole 14. The outer ring 13 and the inner ring 12 are provided on the outer race and the inner race of the disc 11, respectively. The outer ring 13 is inseparably connected with the disc 11 as a one-piece structure. The inner ring 12 and the disc body 11 are separably combined to form a split structure. Wherein the inner ring 12 is coupled to the tray body 11 when it is at the lower limit position, and is separated from the tray body 11 when it is at the upper limit position. Also, as can be seen from fig. 3-4, in this embodiment, the lower end of the inner ring 12 is provided with a sealing member 16, and the sealing member 16 seals the gap between the inner ring 12 and the disk 11 when the inner ring 12 is combined with the disk 11, so that the inner ring 12 can be well sealed with the disk 11 without leakage when in the lower limit position. Thus, the disc 1 is suitable for containing the liquid, solid-liquid mixed or solid material 20 so as to complete the fermentation and brewing process of the corresponding material 20.

The lifting of the inner ring 12 is completed by the driving of the inner ring driving mechanism 62. The inner ring driving mechanism 62 is in driving connection with the inner ring 12 and is used for driving the inner ring 12 to ascend and descend between the lower limit position and the upper limit position so as to realize the combination and separation between the inner ring 12 and the disc body 11. Fig. 2-4 illustrate the structure of the inner ring drive mechanism 62.

As shown in fig. 2-4, in this embodiment, the inner ring drive mechanism 62 includes a lift drive mechanism 621, and the lift drive mechanism 621 is drivingly connected to the inner ring 12 to drive the inner ring 12 up and down. Specifically, as shown in fig. 2-3, in this embodiment, a mounting frame 625 is fixedly disposed below the top of the frame 91, and the lifting driving mechanism 621 is disposed on the mounting frame 625 and includes a driving cylinder (e.g., an air cylinder, an electric cylinder, or a hydraulic cylinder), a cylinder tube of the driving cylinder is fixed to the mounting frame 625, and a cylinder rod extends below the mounting frame 625 and is drivingly connected to the inner ring 12 through a first plate 623 and a second plate 624. Wherein the first plate 623 is connected to a rod of a driving cylinder, and the second plate 624 is disposed on a surface of the inner ring 12 near the center of the disc 1 and protrudes from the inner ring 12 toward the center side. Also, the second plate 624 is positioned above the first plate 623 and overlaps the first plate 623. Thus, when the rod of the driving cylinder is contracted, as shown by the broken line in fig. 2 and fig. 4, the first plate 623 pushes the second plate 624 upward, and the inner ring 12 is lifted up, and the inner ring 12 is raised, and when the rod of the driving cylinder is extended, as shown by the solid line in fig. 2 and fig. 3, the first plate 623 falls, and the second plate 624 and the inner ring 12 fall with gravity until they return to the lower limit position, and the second plate 624 overlaps the first plate 623 again, and the inner ring 12 is lowered. As can be seen, the lifting driving mechanism 621 can drive the inner ring 12 to lift. Of course, the structure of the lifting driving mechanism 621 may be modified, for example, the lifting driving mechanism 621 may use other mechanisms such as a linear motor as the power mechanism instead of the driving cylinder.

In addition, as shown in fig. 2 to 4, in this embodiment, the inner ring driving mechanism 62 includes not only the elevation driving mechanism 621 but also the guide 622. The guide 622 is connected to the inner ring 12 for guiding the inner ring 12 during the elevation of the inner ring 12 by the elevation driving mechanism 621. Specifically, as shown in fig. 2 to 4, in this embodiment, a plurality of guides 622 are provided on the mounting frame 625, penetrate through the mounting frame 625, extend vertically downward, and are connected to the first plate 623, for example, in fig. 2 to 4, two guides 622 are respectively disposed on both sides of the lift driving mechanism 621, and both penetrate vertically through the mounting frame 625 and are connected to the first plate 623. In this way, the guide 622 can play a guiding role in the process that the lifting driving mechanism 621 drives the inner ring 12 to lift, so as to guide the inner ring 12 to lift more smoothly. The guide 622 may be a guide rod, or may also be a guide rod and a linear bearing, a linear guide rail and a slider, and an oilless bushing and a guide rod.

In the production process, before the material 20 enters the disc 1, the inner ring 12 descends to a lower limit position to be in contact with the disc body 11, and a gap between the inner ring and the disc body 11 is sealed by the sealing piece 16, at the moment, the inner ring 12, the disc body 11 and the outer ring 13 form a sealed container for containing liquid, solid-liquid mixed state or solid material; when the materials 20 are sent into the disc 1 by the feeding mechanism 3 until the subsequent whole brewing and fermentation processes, the inner ring 12 is always at the lower limit position to prevent the materials from leaking; and after the material 20 is fermented or brewed, the inner ring 12 is lifted upwards, so that the discharge hole 14 is communicated with the space of the disc 1 for containing the material 20, the material 20 is conveniently conveyed to the discharge hole 14 by the discharge mechanism 2, and central discharge is realized.

Fig. 5 to 6 show the structure of the discharging mechanism 2 in this embodiment. Referring to fig. 5-6, in this embodiment, the outfeed mechanism 2 does not rotate with the puck 1 and includes a conveyor 21 and an outfeed elevator mechanism 22. The conveyor 21 is disposed above the disc body 11 and extends in the radial direction of the disc 1, that is, the axial direction of the conveyor 21 is in the radial direction of the disc 1. The conveyor 21 can rotate along its own axis of rotation, so that the material can be conveyed in the radial direction of the disc 1, discharging the material. The discharging lifting mechanism 22 is arranged on the frame 91 and is in driving connection with the conveyor 21 to drive the conveyor 21 to lift, so that the conveyor 21 can lift relative to the disc 1, and the conveyor 21 is controlled to contact or separate from the material 20, thereby meeting different requirements of different stages.

When the discharging is not needed, for example, during the feeding or fermentation brewing process, the discharging lifting mechanism 22 can drive the conveyor 21 to ascend, so that the conveyor 21 is separated from the material 20 and does not contact with the material 20, and the conveyor 21 is prevented from influencing the normal feeding or fermentation brewing process. When the material needs to be discharged, the discharging lifting mechanism 22 drives the conveyor 21 to descend, so that the lower edge of the conveyor 21 is tightly attached to the upper surface of the disc body 11, the conveyor 21 is fully contacted with the material 20, at the moment, the conveyor 21 is started, the conveyor 21 conveys the material 20 towards the radial inner side of the disc 1, the material 20 can be conveyed to the discharging port 14 and drops downwards from the discharging port 14, and along with the rotation of the disc 1, the material 20 of the whole disc 1 can be conveyed to the discharging port 14, and the discharging process is completed.

The material 20 falling from the discharge port 14 can be received by the receiving device such as the receiving disc, and then transported to the designated position of the downstream process by the transporting device, in this case, because the discharge port 14 is positioned at the center of the disc 1, the corresponding radial range is smaller, therefore, the diameter of the receiving disc can be smaller, and the receiving disc does not need to occupy larger space.

However, in order to further facilitate the transfer of the material to the downstream process, referring to fig. 2, in this embodiment, a receiving device such as a receiving tray is not arranged below the discharge port 14, but a discharging mechanism 63 is arranged below the discharge port 14, is communicated with the discharge port 14, and extends along the radial direction of the disk 1. In this way, the material 20 falling from the discharge port 14 can directly fall onto the discharge mechanism 63, and is conveyed by the discharge mechanism 63 toward the radial outside of the disk 1. Like this, owing to need not to set up the take-up (stock) pan, consequently, can practice thrift the shared ground space of take-up (stock) pan to, because material 20 need not to fall earlier to the take-up (stock) pan in, outwards transmit again, but can directly outwards be carried by row material mechanism 63, consequently, the material transports more conveniently, and linking between the process is inseparabler, is favorable to improving whole production efficiency.

In addition, as shown in fig. 5 and 7, in this embodiment, the discharging mechanism 2 is further provided with a spraying device 25, and the spraying device 25 comprises a spraying pipe 251, and the spraying pipe 251 sprays liquid such as water toward the material 20 and the conveyor 21 so as to add the liquid to the material 20, or wash the conveyor 21, so that the material 20 is easier to ferment and brew or convey, or the conveyor 21 is cleaner. Among them, as shown in fig. 5, a plurality of nozzles 252 may be provided on the spray pipe 251 to further improve the spraying effect.

As shown in fig. 5-6, in this embodiment, the conveyor 21 is embodied as a screw conveyor 23. It is understood that other variations of the conveyor 21 are possible, for example, referring to fig. 7-8, the conveyor 21 may also be a flight conveyor 24.

Fig. 9 to 10 show the structure of the feed mechanism 3 in this embodiment. As shown in fig. 9 to 10, in this embodiment, the feed mechanism 3 is disposed above the tray body 11, does not rotate with the disk 1, and includes a first conveyor 31 and a second conveyor 32. Wherein, the first conveying device 31 and the second conveying device 32 are both arranged on the feeding frame 33 connected with the frame 91 and both extend along the radial direction of the disc 1. The first conveyor 31 is arranged immovably in the radial direction of the disc 1, and the first conveyor 31 is provided with a feed opening 34. The second conveying device 32 is disposed below the first conveying device 31, is movably disposed along the radial direction of the disc 1, and is provided with a material distribution port 35, specifically, as shown in fig. 10, a roller 39 is disposed below the second conveying device 32, and the roller 39 is in contact with the feeding frame 33, so that the roller 39 rotates, and the second conveying device 32 can move along the radial direction of the disc 1 on the feeding frame 33. In this way, the second conveyor 32 can move relative to the first conveyor 31 in the radial direction of the disc 1, so that the feeding mechanism 3 can be retracted as a whole to feed the material 20 to different positions of the disc 1.

When feeding is needed, the material 20 falls from the upper-level conveying device into the feeding hole 34 and falls onto the first conveying device 31, then falls onto the second conveying device 32 from the first conveying device 31 and falls onto the disc 1 from the material distribution hole 35 of the second conveying device 32, because the second conveying device 32 can move in the radial direction relative to the disc 1, the second conveying device 32 can convey the material 20 to different radial positions of the disc 1, and because the disc 1 rotates relative to the feeding mechanism 3, the feeding mechanism 3 can convey the material 20 to different circumferential positions of the disc 1, and further, under the cooperation of the feeding mechanism 3 and the disc 1, the material 20 can be uniformly thrown onto the whole disc 1.

Here, as shown in fig. 10, in this embodiment, the first conveying device 31 and the second conveying device 32 are embodied as a belt conveying device 36, but it is understood that, as a modification, as shown in fig. 11 and 12, the first conveying device 31 and the second conveying device 32 may be a screw conveying device 37 or a flight conveying device 38.

Fig. 13 to 14 show the structure of the stirring mechanism 4 in this embodiment. As shown in fig. 13 to 14, in this embodiment, the stirring mechanism 4 is located above the tray body 11, does not rotate with the disk 1, and includes a stirring device 41 and a stirring lift mechanism 42. The stirring device 41 rotates around its rotation axis to stir the material 20, so that the material 20 can uniformly reach the required temperature, humidity and strain environment. The material turning-up and down mechanism 42 is disposed on the frame 91 and is in driving connection with the material turning-up device 41 to drive the material turning-up and down device 41 to control whether the material turning-up device 41 contacts with the material 20. When the material turning device 41 descends to be in contact with the material 20, the material 20 can be turned over, and the material turning function is realized. After the stirring device 41 rises above the material 20, the material is no longer in contact with the material 20, and the material 20 cannot be stirred.

In the production process, when the material turning-up and lifting mechanism 42 lifts the material turning-up device 41 to the highest point, the material turning-up device 41 stops turning up, and when the material turning-up and lifting mechanism 42 drives the material turning-up device 41 to lift up and down at other heights below the highest point, the material turning-up device 41 can turn up the materials 20 with different heights.

Here, as shown in fig. 13, in this embodiment, the upender 41 is embodied as a horizontal flip-flop upender 43, the rotation axis of which is in the horizontal direction. However, the structure of the upender 41 is not limited to this, and for example, as a modification, as shown in fig. 15 to 16, the upender 41 may be a vertical spiral upender 44 including a plurality of spiral upenders whose own rotation axes extend in the vertical direction, and for example, although not shown, the upender 41 may be a rake upender, or the upender 41 may employ a combination of two or more of a horizontal throw-type upender 43, a vertical spiral upender 44, or a rake upender, depending on the material characteristics or the process requirements.

Fig. 17 shows the structure of the temperature adjusting device 5 in this embodiment. Referring to fig. 17, in this embodiment the thermostat 5 is arranged on a frame 91, which does not rotate with the disc 1 and comprises a holder 57 and a heat exchanger 51. The bracket 57 is fixedly attached to the frame 91. The heat exchanger 51 is disposed on the bracket 57 and includes a main pipe 52 and branch pipes 53. The main pipe 52 is provided with a heat exchange medium inlet 54 and a heat exchange medium outlet 55 for the heat exchange medium to enter and exit the heat exchanger 51, respectively. A plurality of branch pipes 53 communicate with the main pipe 52 side by side in a radial direction of the disc 1 and extend downward from the main pipe 52 to contact the material 20. Because the heat exchange medium is introduced into the heat exchanger 51, when the heat exchanger 51 is contacted with the material 20 through the branch pipe 53, the heat exchange medium in the heat exchanger 51 can exchange heat with the material 20, so that the temperature of the material 20 can be adjusted. Moreover, because the disc 1 rotates, the heat exchanger 51 does not rotate along with the disc, and the heat exchanger 51 can rotate relatively, the heat exchanger 51 can also play a role in turning materials. It can be seen that the heat exchanger 51 of this embodiment can control temperature and turn over material, and can be used as a machine for two purposes.

Fig. 18-19 further illustrate the construction of the heat exchanger 51. As shown in fig. 18-19, in this embodiment, the branch tubes 53 of the heat exchanger 51 are generally cylindrical, hollow inside, and have uniform cross-sectional dimensions from top to bottom. Of course, other variations in the shape of the branch 53 are possible. For example, as can be seen in FIGS. 20-21, in some embodiments, the branch tubes 53 are substantially U-shaped, hollow, and have a uniform cross-sectional dimension from top to bottom. For another example, as shown in fig. 22-23, in other embodiments, the branch pipes 53 are substantially rake-shaped, and have hollow interiors and gradually enlarged cross sections from top to bottom. For another example, as shown in fig. 24-25, in some embodiments, the branch pipe 53 is substantially plow-shaped, the interior thereof is hollow, the cross-sectional dimension is uniform from top to bottom, and the outer surface of the branch pipe 53 is provided with a protrusion 56, the protrusion 56 is substantially plow-shaped, the upper portion thereof is smooth, and the lower portion thereof is sharp.

Fig. 26 to 27 show the structure of the turntable mechanism 61 in this embodiment. Referring to fig. 26-27, in this embodiment, the disc 1 is rotatably mounted on a frame 91 and is driven to rotate by a turntable mechanism 61. In particular, the disk 1 is supported at its central portion by a central bearing 614 (for example a central rolling bearing) and at its outer edge by a first idler 613, so that the disk 1 can rotate with respect to the frame 91 about a longitudinal rotation axis located in the centre of the disk 1. The turntable mechanism 61 includes a turntable driving mechanism 611 and a first transmission mechanism 612. The turntable driving mechanism 611 is in driving connection with the disc 1 through the first transmission mechanism 612, and is used for driving the disc 1 to rotate. The turntable driving mechanism 611 is disposed at the outer edge of the disk 1 and includes one, two or more motors. The first transmission 612 is disposed at the outer edge of the disc 1 and includes a gear and teeth or pins located at the entire circumference of the disc 1. The teeth or pins are drivingly connected to the turntable drive 611 via gears such that when the turntable drive 611 is activated, the disc 1 as a whole can be driven to rotate automatically about the longitudinal axis of rotation. In this way, when the turntable driving mechanism 611 is activated, the disk 1 as a whole can be driven to rotate automatically about the longitudinal rotation axis.

Because the disc 1 can rotate around the longitudinal rotation axis under the action of the turntable mechanism 61, and the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 do not rotate around the longitudinal rotation axis, therefore, the relative rotation around the longitudinal rotation axis between the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 and the disc 1 can be realized, so that along with the rotation of the disc 1, the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 can reach different circumferential positions of the disc 1, and discharging, feeding, material turning and temperature adjustment are carried out at different circumferential positions, and finally, the whole-circumference discharging, feeding, material turning and temperature adjustment of the disc 1 are realized.

The rotation of the disc 1 is convenient for realizing the whole-circle discharging, feeding and turning, and is also beneficial to the uniform fermentation of the material 20. Furthermore, if the material 20 needs to be kept still during the fermentation process, the disc 1 may be kept still and not rotated during the whole fermentation process or for a certain period of time during the fermentation process.

Fig. 28 to 29 show the structure of the ventilation device 7 in this embodiment. Referring to fig. 28-29, in this embodiment, the koji making machine 10 is in a closed koji making chamber 78 and is ventilated by the ventilation device 7 into the koji making chamber 78, so that hot and cold air passes through the material 20 to directly exchange heat with the material 20 to adjust the temperature of the material 20. The ventilation device 7 includes a blower 71, an air duct 72, a heat exchanger 73, and a regulating valve 74. The blower 71 communicates with the inside and outside of the chamber through an air duct 72 to drive air into the texturing chamber 78. An adjusting valve 74 and a heat exchanger 73 are arranged in the air pipe 72. The damper valve 74 regulates the air flow. The heat exchanger 73 adjusts the temperature of the air flowing into the room.

As a modification of the ventilating device 7 shown in fig. 28 to 29, the fan 71 may be directly communicated with the indoor space without providing the heat exchanger 73 in the duct 72 and heating the air with a heater or hot steam or cooling the air with cooling water or a refrigerating air conditioner, or the duct 72 and the heat exchanger 73 may be eliminated. In addition, as shown in fig. 30 to 31, when the koji making chamber 78 is a non-closed space and the koji making chamber 78 communicates with the outside through the window 75, the ventilation device 7 may include only the fan 71 and control ventilation by controlling the opening and closing of the fan 71 and the opening degree of the window 75 during the production process.

Fig. 32 to 35 show the first heat exchange system 81 and the structure of the disk 1 associated with the first heat exchange system 81 in this embodiment. As shown in fig. 32-35, in this embodiment, the disc body 11 and the outer ring 13 of the disc 1 are provided with a first cavity 151 and a second cavity 152, respectively, so that both the disc body 11 and the outer ring 13 are of a sandwich structure. The first heat exchange system 81 is disposed below the tray body 11 and is configured to introduce a heat exchange fluid into the first cavity 151 and the second cavity 152, so as to adjust the temperature of the material 20 by using the heat exchange between the heat exchange fluid and the material 20.

Among them, as shown in fig. 32 to 33, the first heat exchange system 81 of this embodiment includes a first shell 811, a second shell 812, an inlet pipe 81a, and an outlet pipe 81 b. The first housing 811 is fixedly provided to the lower surface of the disc body 11 such that the first housing 811 can rotate together with the disc 1. The second housing 812 is disposed under the first housing 811, and a bearing 816 is disposed between the second housing 812 and the first housing 811, an outer ring of the bearing 816 is engaged with the second housing 812, and an inner ring of the bearing 816 is engaged with the first housing 811, so that the second housing 812 may not rotate when the first housing 811 and the disk 1 rotate. A packing 815 is provided on the second housing 812 to seal a gap between the second housing 812 and the first housing 811, thereby preventing leakage of the heat exchange fluid. The inlet pipe 81a and the outlet pipe 81b are connected to the second housing 812 and communicate with the entire circumference of the first chamber 151 inside the tray body 11 through the second housing 812 and the first housing 811. Control valves 817 are provided on both the inlet pipe 81a and the outlet pipe 81b to regulate the flow rate of the heat exchange fluid. Although not shown, it is understood that a pump may be provided on the inlet pipe 81a and/or the outlet pipe 81b to drive the flow of the heat exchange fluid.

Specifically, as shown in fig. 33, in this embodiment, an inlet 818 and an outlet 819 are provided in the second housing 812 so as to be spaced apart from each other. The inlet tube 81a and the outlet tube 81b are connected to the inlet port 818 and the outlet port 819, respectively. The inlet port 818 is located close to the inner ring 12 with respect to the discharge port 819 in the radial direction of the disk 1, and at this time, the inlet port 818 is located radially inside the discharge port 819 and the inlet pipe 81a is located radially inside the discharge pipe 81 b. Meanwhile, as shown in fig. 33, the first housing 811 is provided with an inlet ring groove 813 and an outlet ring groove 814 which are spaced apart from each other. The inlet ring groove 813 and the outlet ring groove 814 are circular ring grooves, which are sequentially arranged in the direction from the inner ring 12 to the outer ring 13, are respectively communicated with the inlet pipe 81a and the outlet pipe 81b through the inlet port 818 and the outlet port 819, and are both communicated with the first cavity 511 inside the disk body 11, so that the heat exchange fluid flowing from the inlet pipe 81a to the disk 1 can sequentially flow into the disk body 11 through the inlet port 818 and the inlet ring groove 813, and the heat exchange fluid flowing through the disk body 11 and the outer ring 13 can sequentially flow out through the outlet ring groove 814, the outlet port 819 and the outlet pipe 81 b.

Since the second housing 812 to which the inlet pipe 81a and the outlet pipe 81b are connected does not rotate with the disk 1, the inlet pipe 81a and the outlet pipe 81b may not rotate during the rotation of the disk 1, and therefore, the inlet pipe 81a and the outlet pipe 81b may not have a winding problem due to the rotation with the disk 1.

In addition, the inlet ring groove 813 and the discharge ring groove 814 are arranged along the whole circumference of the disc 1 and are always communicated with the disc 1, so that the flow of the heat exchange fluid is not influenced by the rotation of the disc 1, and no matter which angle the disc 1 rotates, the heat exchange fluid can enter and exit the disc body 11 through the inlet ring groove 813 and the discharge ring groove 814 to exchange heat with the material 20.

In order to make the inlet ring groove 813 and the outlet ring groove 814 always communicate with the disc 1 during the rotation of the disc 1, in this embodiment, as shown in fig. 34 to 35, a plurality of sets of inlets 157 and outlets 158 are provided on the bottom wall of the disc body 11, the plurality of sets of inlets 157 and outlets 158 are arranged along the circumferential direction of the disc body 11 at intervals on the entire circumference of the disc body 11, and the inlet 157 and the outlet 158 of each set of inlets 157 and outlets 158 communicate with the inlet ring groove 813 and the outlet ring groove 814, respectively, so that the inlet ring groove 813 and the outlet ring groove 814 can always communicate with the disc 1 during the rotation of the disc 1.

Specifically, as shown in fig. 34-35, in this embodiment, first chamber 151 inside disk body 11 is partitioned into a plurality of heat exchange chambers 153, the plurality of heat exchange chambers 153 are distributed along the entire circumference of disk body 11, and a set of inlet 157 and outlet 158 are provided on the bottom wall of each heat exchange chamber 153 such that each heat exchange chamber 153 communicates with inlet ring groove 813 and outlet ring groove 814. Also, as can be seen from fig. 34-35, in this embodiment, each heat exchange chamber 153 has a first partition 154 and a second partition 155 disposed therein. The first partition 154 extends in the radial direction of the disk 1, and divides the inside of the heat exchange chamber 153 into a first space 15a and a second space 15b located on both sides of the first partition 154 in the circumferential direction of the disk 1. The inlet 157 and the outlet 158 are located in the first space 15 a. A second partition 155 is provided in the first space 15a and between the inlet 157 and the outlet 158 in the radial direction of the disc 1 to partition the inlet 157 and the outlet 158, preventing the heat exchange fluid flowing into the heat exchange chamber 153 from the inlet 157 from directly flowing out of the outlet 158 without passing through the disc body 11. Further, as shown in fig. 35, in this embodiment, the first partition plate 154 has no space from the outer ring 13 but has a space from the inner ring 12, so that the first space 15a and the second space 15b communicate with each other on the side close to the inner ring 12 but are isolated from each other on the side close to the outer ring 13 and do not communicate with each other. Meanwhile, as shown in fig. 35, in this embodiment, the first space 15a communicates at a radially outer end with the outflow port O of the second chamber 152 located inside the outer ring 13, and the second space 15b communicates at a radially outer end with the inflow port I of the second chamber 152. Further, a plurality of baffles 156 are provided in each of the first space 15a and the second space 15b, so that a baffled flow path is formed in each of the first space 15a and the second space 15b, and the heat exchange fluid flows in a zigzag manner in each of the first space 15a and the second space 15 b.

With the above arrangement, during the rotation of the disk 1, the heat exchange fluid flowing from the inlet pipe 81a into the inlet ring groove 813 can flow into the heat exchange chambers 153 via the inlets 157 of the heat exchange chambers 153, and the heat exchange fluid entering each heat exchange chamber 153 first enters the first space 15a, cannot flow toward the outlets 158 toward the radial outer side due to the blocking of the second partition 155 in the first space 15a, but can flow toward the radial inner side of the disk 1 first, and when flowing to the inner end of the first partition 154, flows into the second space 15b via the space between the first partition 154 and the inner ring 12, and is turned back in the second space 15b to flow toward the radial outer side of the disk 1, and when the heat exchange fluid flows toward the radial outer side of the disk 1 to the outer end of the first partition 154 in the second space 15b, since there is no space between the first partition 154 and the outer ring 13, therefore, the heat exchange fluid does not directly flow back into the first space 15a, but flows into the second chamber 152 through the inflow port I of the second chamber 152, flows back into the first space 15a from the outflow port O of the second chamber 152 after flowing through the second chamber 152, then flows toward the outlet 158, flows into the discharge ring groove 814 from the outlet 158, and finally flows into the discharge pipe 81 b.

It can be seen that, based on the above arrangement, the heat exchange fluid can flow through the disc body 11 first, then flow through the outer ring 13, and when flowing through the disc body 11, can flow radially inwards first, then flow radially outwards, and the whole flow process is orderly controllable, and can control the temperature of the materials 20 at different radial positions and different height positions on the disc 1 in order, which is beneficial to enabling the materials 20 on the whole disc 1 to reach the temperature capable of better meeting the process requirements.

Fig. 36-37 show the flow path inside disk 11 when second chamber 152 is not provided in outer ring 13. As shown in fig. 36 to 37, when the second chamber 152 is not provided in the outer ring 13, a plurality of heat exchange chambers 153 may still be provided in the tray body 11, and the first and second partitions 154 and 155 may still be provided in the heat exchange chambers 153 to divide the inside of the heat exchange chambers 153 into the first and second spaces 15a and 15b, but the main difference is that the first and second spaces 15a and 15b no longer communicate with the inside of the outer ring 13 near one end of the outer ring 13 but are separated from the outer ring 13, and the second space 15b communicates with a portion of the first space 15a on the side of the outlet 158 by providing a space between the outer ring 13 and the first partition 154, so that the heat exchange fluid flowing into the second space 15b does not flow into the outer ring 13 any longer but directly flows back into the first space 15a from the space between the outer ring 13 and the first partition 154 to flow out from the outlet 158. In this case, the heat exchange fluid does not exchange heat with the material 20 at the outer ring 13, and the heat exchange fluid turns back only in the tray 11 to exchange heat with the material 20.

As an alternative to the first heat exchange system 81 shown in fig. 32-37, as shown in fig. 38, the koji making machine 10 may comprise a second heat exchange system 82, the second heat exchange system 82 comprising a reservoir 821, a level gauge 822, an inlet valve 823 and an outlet valve 824. The reservoir 821 is disposed below the disc 1 and contains liquid such as water therein. The disc 1 is at least partially soaked in the liquid storage tank 821, so that the liquid in the liquid storage tank 821 can exchange heat with the material 20 on the disc 1, the temperature of the material 20 is changed, and the soaking type temperature regulation process is realized. A level gauge 822 is disposed on the reservoir 821 for detecting the level of the liquid in the reservoir 821 to avoid too much or too little liquid. The liquid inlet valve 823 and the liquid outlet valve 824 are respectively disposed on a liquid inlet pipeline and a liquid outlet pipeline of the reservoir 821 to control whether to inject liquid into the reservoir 821 or discharge liquid from the reservoir 821.

A second embodiment shown in fig. 39-46 will now be described.

As shown in fig. 39-46, in this second embodiment, the koji-making machine 10 still comprises the disc 1, the discharging mechanism 2, the feeding mechanism 3, the upender mechanism 4, the temperature regulating device 5, the ventilator 7, the first heat exchange system 81 and the frame 91, but no longer comprises the turntable mechanism 61, but comprises the rotating frame 92 and the rotating frame mechanism 93, because this embodiment has an important difference from the aforementioned first embodiment shown in fig. 1-37 in that the disc 1 is not rotated any more, but becomes the discharging mechanism 2, the feeding mechanism 3, the upender mechanism 4 and the temperature regulating device 5.

Differences of the second embodiment from the first embodiment will be mainly described next, and other undescribed parts can be understood by referring to the description of the first embodiment.

In this second embodiment, as shown in fig. 39-42, the disc 1, although still in the form of an annular groove, is not rotatably mounted on the frame 91, but is not rotatably mounted on the frame 91, in which case, in order to achieve a relative rotation between the discharge mechanism 2, the feed mechanism 3, the upender mechanism 4 and the temperature control device 5 and the disc 1, as shown in fig. 39-42, the starter propagation machine 10 comprises a rotating frame 92, the rotating frame 92 is rotatably mounted, and the discharge mechanism 2, the feed mechanism 3, the upender mechanism 4 and the temperature control device 5 are all mounted on the rotating frame 92. Meanwhile, the koji making machine 10 includes a rotating frame mechanism 93, and the rotating frame mechanism 93 is in driving connection with the rotating frame 92 to drive the rotating frame 92 to rotate, and further drive the discharging mechanism 2, the feeding mechanism 3, the stirring mechanism 4 and the temperature adjusting device 5 to rotate.

Specifically, as shown in fig. 39 to 42, in this embodiment, the center of the rotary frame 92 is supported by a self-aligning bearing 934, and the edge of the rotary frame 92 is supported by a second idler 933, so that the rotary frame 92 can be rotatably disposed. And the rotating frame mechanism 93 comprises a frame body driving mechanism 931 and a second transmission mechanism 932, wherein the frame body driving mechanism 931 is in driving connection with the rotating frame 92 through the second transmission mechanism 932 and is used for driving the rotating frame 92 to rotate. Wherein, a rail 935 is provided below the second supporting roller 933 to guide the rotation of the rotating frame 92. The track 935 may be fixed to the frame 91. In addition, a frame body driving mechanism 931 is provided at the outer periphery of the rotating frame 92 and includes one, two or more motors. The second transmission 932 is disposed on the outer edge of the disc 1 and is a gear pin transmission.

Based on the above arrangement, when the frame driving mechanism 931 is started, the rotating frame 92 can be driven around the longitudinal rotation axis located at the center of the disk 1, so that the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 located on the rotating frame 92 can rotate together with the rotating frame 92, thereby realizing the relative rotation between the discharging mechanism 2, the feeding mechanism 3, the material turning mechanism 4 and the temperature adjusting device 5 and the disk 1.

Through the mode that sets up swivel mount 92, realize the relative rotation between discharge mechanism 2, feed mechanism 3, stirring mechanism 4 and attemperator 5 and disc 1, it is more simple and convenient.

And, since the disc 1 does not rotate, the problem of winding of the pipes is not caused, and thus, the structure of the first heat exchange system 81 can be simpler. As shown in fig. 45, in this second embodiment, only the plate body 11 of the disc 1 adopts a sandwich structure, the first chamber 151 is provided inside, no sandwich is provided in the inner ring 12 and the outer ring 13, and the first heat exchanging system 81 no longer includes the first shell 811 and the second shell 812 which are relatively rotatable, but includes the inlet pipe 81a and the outlet pipe 81b which are directly connected to the plate body 11. Since the disk 1 is not rotated, even if the inlet pipe 81a and the outlet pipe 81b are directly connected to the disk body 11, the inlet pipe 81a and the outlet pipe 81b do not have a problem of being wound by rotation, which is simple and convenient.

Fig. 46 shows a schematic view of the flow path on the disk body 11 in this embodiment. As shown in fig. 46, in this embodiment, the first chamber 151 in the disc body 11 is still partitioned into a plurality of heat exchange chambers 153, and these heat exchange chambers 153 are arranged along the circumferential direction of the disc 1, and are distributed over the entire circumference of the disc body 11. And, an inlet 157 and an outlet 158 are provided on the bottom wall of each heat exchange chamber 153, and the inlet 157 and the outlet 158 are respectively communicated with the inlet pipe 81a and the outlet pipe 81 b. Meanwhile, a plurality of baffle plates 156 are provided in each heat exchange chamber 153 to form a baffled flow path. Thus, the heat exchange fluid entering the tube 81a can enter the heat exchange cavities 153 through the inlet 157, and after being turned back for multiple times in each heat exchange cavity 153, the heat exchange fluid flows out from the outlet 158 to the discharge tube 81b, and finally the temperature of the material 20 on the whole tray body 11 is adjusted.

As shown in fig. 43 and 44, in the second embodiment, the inner ring 12 of the disk 1 can be raised and lowered relative to the disk body 11 by the inner ring driving mechanism 62, but the inner ring driving mechanism 62 is provided in a slightly different manner from the first embodiment. As shown in fig. 43-44, in this second embodiment, the inner ring driving mechanism 62 is no longer suspended below the frame 91, but is installed at the discharge port 14 located at the center of the tray 11, and is connected with the inner ring 12 through the connecting plate 626. Specifically, as shown in fig. 43 to 44, in this embodiment, the elevation drive mechanism 621 of the inner ring drive mechanism 62 is provided below the inner ring 12. The guide 622 passes through the side wall of the spout 14 from bottom to top. The connecting plate 626 is connected to a side surface of the inner ring 12 facing the longitudinal centerline of the disc 1. The guide 622 is connected at both ends thereof to the elevation driving mechanism 621 and the connection plate 626, respectively. In this way, the elevation driving mechanism 621 is connected to the inner ring 12 through the guide 622 and the connection plate 626, so that the elevation driving mechanism 621 can lift up the inner ring 12 by lifting up the inner ring 12. After the inner ring 12 rises, the discharging mechanism 2 can convey the material 20 to the discharging hole 14, so as to realize central discharging.

In summary, the koji making machine 10 provided by the embodiment of the present disclosure can conveniently realize the discharging of the circular groove shaped disc, and can more effectively control the material temperature, thereby realizing a better fermentation brewing effect.

The above description is only exemplary of the present disclosure and is not intended to limit the present disclosure, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of the present disclosure.
