Further, after the juice discharging stage is finished, and before the slag discharging stage is started, a pressurizing stage is further arranged: the liquid discharge assembly is closed, and the steam generating device introduces steam into the pulping chamber for pressurization.

Furthermore, in the pressurizing stage, steam is continuously or intermittently introduced into the pulping chamber.

Furthermore, the thick liquid is the raw thick liquid that does not boil out, and at the juice discharge in-process, steam generator lets in steam in order to heat raw thick liquid to the slurrying cavity, and at the slag discharge in-process, the foam parcel thick liquid sediment that forms in the slurrying cavity is discharged by flowing back the liquid subassembly.

Further, the raw slurry discharged into the slurry receiving cup is raw slurry, wherein the raw slurry in the slurry receiving cup is boiled by steam.

Furthermore, before the control method is applied to the food processing machine for pulping, the introduced steam is used for carrying out steam sterilization on the pulping chamber and the liquid discharge assembly;

or the control method is applied to the cleaning process after pulping, and the introduced steam drives the residue and/or the cleaning water in the pulping chamber to be discharged by the liquid discharge assembly.

The control method of the food processor of the invention comprises the following steps: when the liquid discharge assembly is in an opening state, the steam generating device continuously or intermittently introduces steam into the pulping chamber, and the steam is discharged out of the pulping chamber through the liquid discharge assembly. The control method can be applied to the working process of the food processor. Compared with the prior art, the control method of the invention can discharge impurities in the pulping chamber, such as stains, residues, oil stains, even pulp residues and the like, out of the pulping chamber by using steam, not only effectively realizes the functions of automatic sterilization, automatic pulp discharge, no need of hand washing, automatic pulp heating and the like of the food processing machine, but also has better cleaning and sterilizing effects, cleaner pulp discharge, less water consumption for washing and even no need of washing water compared with the existing full-automatic soybean milk machine, and has simpler scheme for heating the pulp compared with the existing food processing machine capable of heating the pulp by using steam.

The control method can be applied to high-temperature sterilization and disinfection of the cavity wall of the pulping chamber and the liquid discharge assembly by the introduced steam before pulping. On one hand, the temperature of the steam is higher, and the high-temperature steam can heat the cavity wall surface of the pulping chamber after filling the pulping chamber, so that the temperature of the cavity wall surface is rapidly increased, and the effects of pasteurization and sterilization are achieved. On the other hand, high temperature steam can liquefy rapidly, condense into the drop of water after meetting cold cavity at the in-process of letting in the slurrying cavity, and the drop of water slides down along the chamber wall of slurrying cavity, adsorbs away mould, spot, oil stain and dust on the chamber wall simultaneously, and the drop of water that condenses before the steam that follow-up lets in can also accelerate promotes downwards discharges through flowing back subassembly (the route direction that steam flows).

Meanwhile, the control method can also be applied to the discharging process of the slurry, the introduced steam can quickly discharge the slurry and the slurry slag, the slurry slag is discharged more cleanly, and the water consumption is low. Mainly because: first, when the steam of high temperature lets in the slurrying cavity and meets cold chamber wall, can liquefy and condense into the drop of water, the drop of water of condensation is under the action of gravity, scours the chamber wall to adsorb the residue on the chamber wall, and, when the drop of water collects the chamber bottom wall, can further mix with the thick liquid sediment of chamber bottom wall, thereby form the better thick liquid of mobility once more and discharge through flowing back subassembly. Secondly, after food preparation machine has prepared thick liquid, the surface that is located the thick liquid can form the one deck thick liquid foam to hang on the chamber wall, and high-temperature steam lets in behind the slurrying cavity, and the pressure in the slurrying cavity can continuous increase, and under the dual function of high temperature and pressure, tiny thick liquid foam can break the bubble and disappear, and mix with the thick liquid sediment of chamber diapire under the water droplet scour of condensation. And the liquid discharge assembly is positioned at the bottom of the pulping chamber and is a main circulation channel for discharging steam, so that the steam can carry mixed juice and pulp residues to be discharged through the liquid discharge assembly. Thirdly, when the slurry prepared by the food processor is raw slurry, because the temperature of the steam introduced into the pulping chamber is higher, the raw slurry which is not discharged can generate a large amount of foam and wrap the slurry residue on the bottom wall of the chamber under the heating action of the high-temperature steam, thereby greatly improving the fluidity of the slurry residue and being more beneficial to the discharge of the slurry residue. Therefore, even if water is not fed into the pulping chamber (the fluidity of the pulp is improved after the pulp and the water are mixed), the pulp can be discharged out of the pulping chamber through the liquid discharge assembly under the multiple actions of the steam after the steam is fed into the pulping chamber for a certain time.

Secondly, the control method of the invention can also be applied to the cleaning process after slurry discharge, high-temperature steam introduced into the pulping chamber can be liquefied and condensed into water drops, the condensed water drops scour the chamber wall under the action of gravity, and simultaneously adsorb residues on the chamber wall and are discharged through the liquid discharge assembly.

Even if water is used for cleaning in the cleaning process, the control method can also be used for introducing steam into the pulping chamber in the wastewater discharge process so as to improve the air pressure in the pulping chamber to discharge the cleaning water more quickly, and particularly when the pulping chamber is a closed chamber, the introduced steam not only can discharge the wastewater more effectively, but also can realize the cleaning of the chamber wall by the steam and has less cleaning water amount compared with the prior art.

In addition, the control method can also be applied to heating and boiling of the slurry, when the raw slurry in the pulping chamber is discharged into the slurry receiving cup, steam is introduced into the pulping chamber and enters the slurry receiving cup through the liquid discharge assembly, so that the raw slurry in the slurry receiving cup is heated and boiled. Compared with the existing food processing machine which needs to be provided with an independent steam pipeline and connected with the complicated steam heating of the pulp cup, the scheme has the advantages that the structure is simpler, after the pulp cup is boiled, a consumer can directly take away the pulp cup to drink, and the operation is very convenient.

Drawings

The invention will be further described with reference to the accompanying drawings in which:

FIG. 1 is a schematic diagram of a food processor according to an embodiment of the present invention;

FIG. 2 is a schematic structural diagram of a food processor according to an embodiment of the present invention.

Detailed Description

The first embodiment is as follows:

as shown in fig. 1, which is a food processor according to a first embodiment of the present invention, the food processor includes a machine body 1, a grinding cup 2 installed in the machine body 1, and a cup cover 3 covering the grinding cup 2, wherein a silicone plug 31 is installed on the cup cover 3, and the grinding cup 2 and the cup cover 3 enclose to form a non-closed pulping chamber. Meanwhile, a water tank 4 is installed on one side of the machine body 1, a heating device (not shown in the figure) for heating the water tank and generating steam is arranged in the water tank 4, a water inlet and steam inlet nozzle 21 for feeding water or steam into the crushing cup 2 is arranged on the wall of the crushing cup 2, and the water inlet and steam inlet nozzle 21 is communicated with the water tank 4 through a pipeline (not shown in the figure). Wherein the water tank 4 and the heating device form a steam generating device for introducing steam into the pulping chamber. In addition, a liquid outlet (not marked in the figure) is arranged at the bottom of the crushing cup 2, a liquid outlet assembly 5 is arranged at the liquid outlet, wherein the liquid outlet assembly 5 comprises a liquid outlet pipe 51, a pulp receiving cup 6 and a waste water box (not shown in the figure) are arranged below the liquid outlet pipe 51, and the waste water box is positioned in an installation cavity (not shown in the figure) of the machine body 1 and is arranged side by side with the pulp receiving cup 6. The drain pipe 51 of the present embodiment can be rotated between the slurry receiving cup 6 and the waste water box to perform slurry discharge and waste water discharge, respectively.

The food processor of the present embodiment has a control method of: when the liquid discharge assembly is in an opening state, the steam generating device continuously or intermittently introduces steam into the pulping chamber, and the steam is discharged out of the pulping chamber through the liquid discharge assembly.

The control method can be applied to sterilization and disinfection before pulping of the food processing machine. When the food processor is powered on and started, the heating device heats water in the water tank and generates steam, and the steam is introduced into the pulping chamber from the water inlet and steam inlet nozzle. For the embodiment, the pulping chamber is of an unsealed structure, the liquid discharge assembly is a main passage of steam, a small part of the steam can escape out of the pulping chamber through the plug arranged on the cup cover, and the majority of the steam can directly discharge out of the pulping chamber through the liquid discharge assembly. On one hand, the temperature of the steam is higher, and the high-temperature steam can heat the cavity wall surface of the pulping chamber after filling the pulping chamber, so that the temperature of the cavity wall surface is rapidly increased, and the effects of pasteurization and sterilization are achieved. On the other hand, high temperature steam can liquefy rapidly, condense into the drop of water after meetting cold cavity at the in-process of letting in the slurrying cavity, and the drop of water slides down along the chamber wall of slurrying cavity, adsorbs away mould, spot, oil stain and dust on the chamber wall simultaneously, and the drop of water that condenses before the steam that follow-up lets in can also accelerate promotes downwards, discharges to the waste water box through flowing back subassembly (the route direction that steam flows). Thus, for this embodiment, steam may be used to sterilize and disinfect the pulping chamber and drain assembly prior to pulping.

Meanwhile, the control method of the food processor of the present embodiment can also be applied to the discharge process of the slurry. After the slurry is manufactured, the liquid discharge assembly is opened, and the slurry in the pulping chamber can be discharged into the slurry receiving cup through the liquid discharge assembly. However, in the pulping process, under the stirring of the crushing blade, more fine pulp foam can be formed on the surface of the pulp, and the fine pulp foam can be hung on the wall of the cavity and cannot be discharged along with the pulp discharge due to the viscosity of the pulp foam. In the discharging process of the slurry in the embodiment, the control method can effectively solve the problems of slurry foam wall hanging and incomplete slurry foam discharging. Because the introduced high-temperature steam can be condensed into water drops after meeting the cold cavity wall on one hand, the water drops slide down along the cavity wall, and fine pulp foam can be washed away downwards. Furthermore, when the slurry foam is heated by the high-temperature steam, the air in the slurry foam expands due to the heat, and the slurry foam is broken. On the other hand, when steam is introduced into the pulping chamber, the pressure in the chamber is continuously increased, and pulp foam is forced to achieve the purpose of crushing. Thereby realizing that the broken pulp foam is changed into flowing pulp to be collected on the bottom wall of the cavity and flows into the pulp receiving cup through the liquid discharge assembly. Meanwhile, when the pressure in the cavity is increased, the discharge of the slurry is accelerated, the liquid discharge efficiency is improved, and the time required by pulping is reduced.

It should be noted that, in this embodiment, the slurry is a slurry containing no sludge or containing a small amount of sludge, the slurry is stirred by the crushing blade, and then is uniformly mixed and has good fluidity, and the slurry can be easily discharged into the slurry receiving cup by opening the liquid discharge assembly, so that the situation that the slurry or the sludge is not completely discharged rarely occurs. It should be further noted that, in this embodiment, before discharging the slurry and before the liquid discharge assembly is not opened, steam may be introduced into the pulping chamber first to increase the pressure in the pulping chamber, thereby improving the discharge efficiency of the subsequent slurry and reducing the time for discharging the slurry and pulping.

Next, in the present embodiment, when the prepared slurry is raw slurry, after the slurry discharge is finished, the control method of the present embodiment may be further applied to heating and boiling the raw slurry in the slurry cup. At the moment, a steam communicating pipe can be arranged on the liquid discharge pipe to directly extend into the pulp receiving cup, and steam introduced into the pulping chamber enters the pulp receiving cup through the liquid discharge assembly, the liquid discharge pipe and the steam communicating pipe, so that raw pulp in the pulp receiving cup is subjected to steam heating and boiling. This embodiment steam heating thick liquid can not take place the problem of sticking with paste the end, and the nutrient composition that can remain the thick liquid by a wide margin does not run off to, the simple structure of this embodiment steam heating thick liquid compares in prior art, and the back of having boiled out, and the consumer can directly take away and connect the thick liquid cup to drink, and the operation is very convenient.

In addition, for the embodiment, the control method can also be applied to cleaning the pulping chamber after the pulp is discharged. The high temperature steam that lets in the slurrying cavity can liquefy and the condensation becomes the drop of water, and the drop of water that condenses erodees the chamber wall under the action of gravity, adsorbs the residue on the chamber wall simultaneously to in discharging the waste water box through flowing back subassembly, compare in the current soybean milk machine that can realize not having the hand washing, utilize flowing back subassembly open mode, continuously let in steam and wash, need not wash water completely, the slurrying cavity also can be sanitized. Meanwhile, it should be noted that compared with the above-mentioned patent application CN201910481587.5, the pulp residue adhered to the wall of the pulping chamber does not dry for a long time, has low adhesion, and does not need to be purposely soaked and steam softened. Because the step of cleaning the cavity wall of the pulping cavity by using the steam is performed after the pulp discharge is finished, the cavity wall is still in a wet environment, and the pulp residue adhered to the cavity wall can be easily washed away after the steam is condensed into water drops.

Even the cleaning process of this embodiment has the step of intaking washing to the slurrying cavity, the control method of this embodiment, the in-process that also can use the row waste water lets in steam to the slurrying cavity in, can promote the atmospheric pressure in the slurrying cavity and come more quick will wash water discharge to waste water box, the steam that lets in not only more effective discharge waste water, compare in prior art moreover, the washing of chamber wall also can be realized to steam, abluent water consumption and the number of times of intaking also can be still less.

Example two:

fig. 2 is a schematic structural diagram of a second embodiment of the present invention. The difference between the present embodiment and the first embodiment is: in this embodiment, the bowl cover does not have bleeder vent and silica gel stopper, and the slurrying cavity that bowl cover and crushing cup enclose to close and form is the cavity of enclosed construction. When steam is introduced into the pulping chamber, the liquid discharge assembly is the only outlet for discharging the steam.

For the food processor of this embodiment, concentrated soy milk can be prepared. The pulping process comprises the following steps:

1) preparation phase

2) A pulping stage: and the crushing blade is used for stirring and crushing the mixture of the materials and the water in the pulping chamber to prepare thick raw pulp mixed with the pulp juice and the pulp residue.

3) A juice discharging stage: and opening the liquid discharge assembly, and discharging the juice and the pulp residue mixed with the juice into the pulp receiving cup through the liquid discharge assembly.

4) A slag discharging stage: the liquid discharge assembly is kept in an open state, and the residual pulp is discharged into the pulp receiving cup by the liquid discharge assembly.

5) A cleaning stage: and cleaning the pulping chamber, and discharging the cleaned water through a liquid discharge assembly.

6) And (3) a boiling stage: heating and boiling the raw slurry in the slurry cup until the raw slurry is cooked.

In the preparation stage of the pulping process, the liquid discharge assembly is opened, and then steam is passed into the pulping chamber, so that the pulping chamber can be sterilized and disinfected. The principle is the same as the first embodiment, and is not described herein again.

Moreover, for the embodiment, since the prepared slurry is thick slurry, the thick slurry has poor fluidity, after the liquid discharge assembly is opened, the slurry with good fluidity and a part of the slurry residue uniformly mixed with the slurry can be discharged to the slurry receiving cup through the liquid discharge assembly, and as the slurry in the slurry making chamber is less and less, the accumulated slurry residue is difficult to discharge from the liquid discharge assembly, and as the slurry residue in the raw slurry is rich in nutrition, if the slurry residue cannot be discharged into the slurry receiving cup to be boiled together, great waste is caused, and the slurry residue is remained in the slurry making chamber and is difficult to clean. In the prior art, water is generally fed for many times so as to wash the pulp residue into the pulp receiving cup, so that the water is fed for many times to wash the residue, and after the residue is washed for many times, the concentration of the pulp in the pulp receiving cup is greatly diluted, so that the requirements of consumers who like thick pulp on taste cannot be met.

In this embodiment, the above control method may also be applied in the juice draining stage, that is: when the liquid drainage assembly is in an open state, the steam generating device introduces steam into the pulping chamber, and the steam discharges the juice into the pulp receiving cup through the liquid drainage assembly. Like the first embodiment, steam is introduced in the juice discharging stage, so that pulp foam on the surface of the cavity wall can be well crushed and washed clean, and the juice discharging efficiency is accelerated.

It should be noted that, in this embodiment, the pulping chamber is a closed structure, the juice discharging is slow by using the gravity of the pulp, and the juice cannot be naturally discharged at the later stage of the juice discharging, so that in the process of the juice discharging, steam is continuously or intermittently introduced to increase the pressure in the pulping chamber, and the steam pressure is used to accelerate the juice discharging. And when the steam is used for discharging juice, the steam is also condensed into water drops on the cavity wall, and further pulp residue, pulp foam, residual stains and the like on the cavity wall are washed away.

Meanwhile, the control method can also be applied to a slag discharging stage, as the slurry prepared by the food processor is uncooked slurry, no matter the slurry is in a juice discharging stage or a slag discharging stage, the introduced high-temperature steam can heat the slurry with good fluidity, so that the slurry mixed with the slurry and the slag can be heated in the slurry making chamber to form a large amount of foam and wrap the slurry and the slag, as the slurry and the slag are wrapped by the foam, the fluidity of the slurry and the slag are greatly improved, and the foam with good fluidity drives the slurry and the slag to be discharged into the slurry receiving cup together through the liquid discharging assembly. Therefore, in the embodiment, even if the water and the slag are not injected into the pulping chamber in the slag discharging process, the pulp and the slag can be discharged through the liquid discharging assembly under the action of the steam after the steam is introduced for a certain time.

In this embodiment, in order to increase the efficiency and time of the slag discharging, a step of feeding water and washing slag into the pulping chamber may be provided after the juice discharging stage is finished and before the slag discharging stage is started. In addition, the step of flushing slag by water inflow can also be arranged in the process of deslagging, namely, water inflow and steam inflow are synchronized. Of course, the slag flushing step of this embodiment obviously has a smaller number of slag flushing times than the multiple slag flushing times of the prior art, and in this embodiment, the water inlet and the steam inlet may not be synchronized. Meanwhile, in order to accelerate the efficiency of slag discharge, a pressurizing stage can be arranged after the juice discharging stage and before the slag discharging stage, namely: the liquid discharge component is closed, and the steam generating device continuously or intermittently introduces steam into the pulping chamber to carry out pressurization. Because the pulping chamber is of a sealing structure, when the pressure boosting stage is completed and the slag discharging stage is started, under the action of pressure, steam can drive pulp slag to enter the pulp receiving cup through the liquid discharging assembly.

It should be noted that, in this embodiment, the steam may be continuously or intermittently introduced only during the juice discharging process to accelerate the juice discharging. Of course, in this embodiment, for the consumers who do not like the beverage with the feeling of dregs, the dregs discharged by the liquid discharge assembly can be controlled to be directly discharged into the waste water box in the stage of discharging dregs, so as to realize the preliminary filtration of the dregs. Also, it should be noted that in this embodiment, compared to the above-mentioned patent application CN201910481587.5, the pulp adhering to the wall of the pulping chamber does not dry for a long time, has less adhesion, and does not require intentional wetting and steam softening. Because the step of discharging the slag in the pulping chamber by using the steam is performed after the juice is discharged, and the pulping chamber has a closed structure, the inside of the pulping chamber is always in a wet environment, and the pulp slag adhered to the wall of the chamber is always in a wet and softened state. Therefore, after the steam is condensed into water drops, the pulp slag adhered to the cavity wall can be easily washed away.

Secondly, for this embodiment, the above control method can also be applied to the cleaning stage to clean the residues and stains on the chamber wall by the water drops condensed by the steam, and then discharge the collected wastewater to the wastewater box. The principle and process of applying the above control method in the cleaning stage are the same as those in the first embodiment, and are not described herein again. It should be noted that, in the cleaning process, the condensed water discharged by the liquid discharge assembly can also be directly discharged to the slurry receiving cup, and the raw thick slurry is mixed and blended, so that the concentration of the slurry cannot be greatly reduced due to the small amount of the discharged condensed water. Therefore, if the condensed water discharged during the washing step can be discharged to the slurry receiving cup for blending, the food processor of this embodiment can remove the waste water box. The structure of the food processor is simpler and the manufacturing cost is lower.

In addition, for the present embodiment, as in the first embodiment, the above control method may also be applied in the boiling stage, and the raw slurry in the slurry cup is heated and boiled by the steam introduced into the slurry making chamber until the raw slurry is boiled.

It is noted that for the food processor of the present invention, the steam generated by the steam generating device may be high purity steam. However, since part of the steam is immediately liquefied into mist or droplets while being ejected from the water inlet and steam inlet nozzle, the steam in this embodiment may be a mixed steam of steam and water.

The food processor of the invention can be a wall-breaking food processor with a lower motor, and can also be a frame-type food processor. It will be appreciated by those skilled in the art that the present invention includes, but is not limited to, those illustrated in the accompanying drawings and described in the foregoing detailed description. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
