The embodiments of the present application will be further explained with reference to the drawings.

Referring to fig. 1 and 2, an embodiment of the present application provides a direct cooling cylinder including:

an inner tube 200 having an accommodating chamber 600 for receiving food therein;

the outer pipe 100 is sleeved outside the inner pipe 200, a heat exchange cavity 310 is arranged between the outer pipe 100 and the inner pipe 200, and the outer pipe 100 is fixedly connected with the outer side of the inner pipe 200 through a connecting part 500;

the first air duct 410 is fixedly connected to the lower side of the outer tube 100, the first air duct 410 is communicated with the heat exchange cavity 310, and the first air duct 410 is used for inputting a refrigeration source in a refrigeration state or outputting a heating source in a heating state;

and a second air duct 420 fixedly connected to the upper side of the outer tube 100, the second air duct 420 being communicated with the heat exchange chamber 310, the second air duct 420 being used for outputting a cooling source in a cooling state or inputting a heating source in a heating state.

In an embodiment, the inner tube 200 and the outer tube 100 may be in any shape, for example, concentric cylindrical tube bodies shown in fig. 1 and fig. 2, a tube diameter of the inner tube 200 is smaller than a tube diameter of the outer tube 100, so that a cavity is formed between the inner tube 200 and the outer tube 100, that is, the heat exchange cavity 310 in this embodiment, if the actual production requirement is met, the shape may be adjusted to other shapes, the heat exchange cavity 310 may be formed between the inner tube 200 and the outer tube 100, the heat exchange cavity 310 is filled with a cooling source or a heating source, most of the surface of the inner tube 200 can be covered, a contact area between the inner tube 200 and the cooling source and the heating source is greatly increased, and the heat exchange effect is effectively increased.

In an embodiment, the outer tube 100 and the inner tube 200 are preferably fixedly connected by the connecting portion 500, so that the assembly is convenient and the processing difficulty is reduced.

It should be noted that the cooling state in the embodiment of the present application is an operating state in which the cooling device continuously inputs the cooling source through the first air duct 410, so that the cooling source enters the heat exchange chamber 310 to exchange heat with the inner tube 200, and is discharged from the second air duct 420. Similarly, the heating state in the embodiment of the present application is an operating state in which the heating device continuously inputs the heating source through the second air duct 420, so that the heating source enters the heat exchange chamber 310 to perform heat exchange with the inner tube 200, and is discharged from the first air duct 410, or an operating state in which the inside of the direct cooling cylinder is sterilized by high temperature. It should be noted that the refrigerating device and the heating device may be apparatuses commonly found in the prior art, such as a refrigerating system composed of a common compressor and an evaporator, and the flow directions of the gas in the refrigerating state and the gas in the heating state are opposite.

It should be noted that, in the embodiment of the present application, it is preferable to provide a first air duct 410 at the lower side of the outer tube 100 and used for inputting the cooling source and outputting the heating source, because liquid-state refrigerant oil easily exists in the cooling source, if two air ducts are provided at the lower side of the outer tube 100 and used for inputting the cooling source and the heating source, respectively, refrigerant oil may remain in an input pipeline of the cooling source, which affects a heat exchange effect, and requires frequent disassembly of the direct cooling cylinder for maintenance, therefore, a first air duct 410 is provided for inputting the cooling source and outputting the heating source in the embodiment of the present application, and the refrigerant oil may be discharged from the first air duct 410 by a reverse air flow in a heating working state, for example, when the ice cream machine is in a cooling state, food in the direct cooling cylinder is cooled to a condensing state by inputting the first air duct 410, after the ice cream machine enters a high-temperature sterilization state, the heating source enters from the second air duct 420, passes through the heat exchange cavity 310 and is discharged from the first air duct 410, and under the action of the air flow, the residual refrigeration oil is discharged from the first air duct 410 at the same time, so that the maintenance frequency is effectively reduced.

Referring to fig. 1 and 2, in another embodiment of the present application, a plurality of blocking portions 320 are further disposed in the heat exchange chamber 310, the blocking portions 320 are hermetically connected to the inner tube 200 and the outer tube 100, and the plurality of blocking portions 320 are annular and provided with openings.

In an embodiment, several blocking portions 320 are provided in the heat exchange chamber 310, which can extend the path length of the gas flow, for example, as shown in fig. 1, a first blocking portion 321 and a second blocking portion 322 are provided, so that a first heat exchange chamber 311, a second heat exchange chamber 312 and a third heat exchange chamber 313 are formed between the inner tube 200 and the outer tube 100, during the cooling process, the cooling source enters the first heat exchange chamber 311 from the first air duct 410, enters the second heat exchange chamber 312 through an opening of the first blocking portion 321, enters the third heat exchange chamber 313 through an opening of the second blocking portion 322, and then is discharged through the second air duct 420, so that the cooling source or the heating source can flow through more regions between the inner tube 200 and the outer tube 100, if there is only one heat exchange chamber 310, it is likely that some regions are not flowed through by the cooling source or the heating source, which affects the heat exchange effect.

In another embodiment of the present application, the number of barriers 320 is at least greater than 1, and two adjacent barriers 320 are staggered from each other in the heat exchange chamber 310.

In an embodiment, the number of blocking portions 320 may be any, for example, as shown in fig. 1 and 2, a first blocking portion 321 and a second blocking portion 322 are disposed from back to front between the inner tube 200 and the outer tube 100, and the first blocking portion 321 and the second blocking portion 322 may be parallel, so that the gas flow is more uniform; the distance between the first blocking portion 321 and the second blocking portion 322 can be adjusted according to actual requirements, and is not described herein again.

Based on the above embodiment, the first blocking portion 321 and the second blocking portion 322 may be provided with one opening, the opening of the first blocking portion 321 is disposed at the upper side, and the opening of the second blocking portion 322 is disposed at the lower side, so that the refrigeration source or the heating source can flow through the outside of the whole inner tube 100, for example, during the refrigeration process, the refrigeration source enters the lower side of the first heat exchange cavity 311 from the first air duct 410, and under the action of the continuously input air pressure of the refrigeration source, the refrigeration source flows to the opening of the first blocking portion 321 located at the upper side, enters the second heat exchange cavity 312 from the opening, flows to the opening of the second blocking portion 322 located at the lower side, enters the third heat exchange cavity 313, flows to the upper side of the inner tube 100, and is discharged from the second air duct 420, so that the refrigeration source can cover the whole heat exchange cavity 310, and the area of heat exchange is effectively increased. It will be understood by those skilled in the art that the specific number of barriers, the distance between them and the number and location of the openings can be adjusted according to the actual requirements of the gas flow, and will not be described in detail herein.

Referring to fig. 1 and 2, in another embodiment of the present application, a second airway tube 420 is provided on the anterior side of the barrier 320.

In one embodiment, the second air duct may be disposed at any position, for example, the second air duct 420 is disposed at the front side of the second blocking portion 322 in fig. 1, so that the flowing distance of the cooling source or the heating source in the heat exchange chamber 310 can be extended, thereby improving the heat exchange effect.

Referring to fig. 1 and 2, in another embodiment of the present application, a first airway tube 410 is provided on the posterior side of barrier 320.

Based on the above embodiment, the first air duct 410 is disposed at the rear side of the first blocking portion 321, and the second air duct 420 is disposed at the front side of the second blocking portion 322, so that the cooling source or the heating source can be ensured to flow through the whole heat exchange cavity 310, and the heat exchange effect is effectively improved. It is understood that the specific position of the first airway tube 410 behind the blocking portion 320 and the specific position of the second airway tube 420 in front of the blocking portion 320 may be adjusted according to actual requirements, and is not limited herein.

Referring to fig. 1, in another embodiment of the present application, the first air duct 410 is obliquely disposed to the outside of the outer tube 100 toward the front side.

In an embodiment, the first air duct 410 and the second air duct 420 may be perpendicular to the outer tube 100, or may be disposed obliquely, in this embodiment, it is preferable that the first air duct 410 and the outer side of the outer tube 100 are tilted, and the tilted direction is toward the front side, that is, the connection between the first air duct 410 and the outer tube 100 is located at the rear side of the orifice of the first air duct 410, so that in a cooling state, a cooling source flows to the rear side of the heat exchange cavity 310 under the inertia effect after being input through the first air duct 410, and further flows to the front side under the effect of the air pressure, thereby ensuring that the cooling source can flow at the rear side of the heat exchange cavity 310, and improving the heat exchange effect. It should be noted that the specific inclination angle of the first air duct 410 can be adjusted according to actual requirements, and is not described herein again.

Referring to fig. 1, in another embodiment of the present application, the first air duct 410 includes a first tube 411 and a second tube 412 that are integrally formed and made of different materials, the second air duct 420 includes a third tube 421 and a fourth tube 422 that are integrally formed and made of different materials, the first tube 411 and the third tube 421 are respectively integrally formed with the outer tube 100, and the first tube 411, the third tube 421 and the outer tube 100 are made of the same material.

In an embodiment, the first pipe 411 and the third pipe 421 are integrally formed with the outer pipe 100, so that the connection stability of the direct cooling cylinder can be improved, the outer pipe 100 is usually made of a metal material, such as stainless steel, and the stability of the connection by welding between the same materials is high and the construction difficulty is low, so that the first pipe 411 and the third pipe 421 are preferably made of the same material as the outer pipe 100, such as stainless steel, and the processing process can be simplified.

In an embodiment, the second tube 412 and the fourth tube 422 are used for being connected with a refrigeration device or a heating device, most of the ventilation pipelines of the refrigeration device or the heating device are copper pipes, such as copper pipes, the manufacturing process of the direct cooling cylinder needs to weld the second tube 412 and the fourth tube 422 with the ventilation pipelines, and the welding difficulty of the same material is low, so that the stability is high, the material of the second tube 412 and the fourth tube 422 can also be red copper, the processing difficulty can be reduced, the connection stability is improved, the specific material can be adjusted according to actual requirements, and the description is omitted.

Referring to fig. 3, in another embodiment of the present application, the connection part 500 includes a first ring welding part 510, a connection member 520, and a second ring welding part 530, both ends of the first ring welding part 510 are fixedly connected to the outer pipe 100 and the connection member 520, respectively, and both ends of the second ring welding part 530 are fixedly connected to the inner pipe 200 and the connection member 520, respectively.

Based on the above embodiment, because the outer tube 100 and the inner tube 200 can both be made of stainless steel, welding is a common fixed connection mode, and can ensure airtightness and stability, if one end of the outer tube 100 is directly welded to the outer wall of the inner tube 200, large-current welding is needed, which easily causes the inner wall of the inner tube 200 to deform or even cause perforation in a high-temperature state, and therefore, the connection portion 500 is arranged between the outer tube 100 and the inner tube 200 in the embodiment, so that the outer tube 100 and the inner tube 200 can be prevented from being directly welded, and flatness of the outer tube 100 and the inner tube 200 can be ensured.

In one embodiment, if the outer tube 100 and the inner tube 200 are connected by a simple connector, a high current welding is also required, so in this embodiment, the connection portion 500 preferably includes the annular first ring-shaped welding portion 510 and the annular second ring-shaped welding portion 530, or may have another shape, and may be used as a support point for welding the connector 520. For example, the inner pipe 100 and the connecting member 520 are welded by a small current at the inner and outer sides, so as to reduce the unevenness of the inner wall of the inner pipe 100 caused by the large current welding, thereby damaging the roundness of the inner pipe 100 and affecting the friction between the stirring shaft and the inner wall of the inner pipe. Therefore, the inner pipe 100 and the connecting member 520 are welded together in two annular welding processes. The welding of the outer tube 200 and the connecting piece 520 can be performed with high current, the friction between the stirring shaft and the inner wall of the inner tube is not affected by the welding deformation of the high current, and the air tightness of the heat exchange chamber 300 can be ensured by the high current welding.

In another embodiment of the present application, the connector 520 is a flange.

In an embodiment, since the inner tube 100 and the outer tube 200 are both cylindrical tubes, the structure can be simplified by using the flange as the connecting member, for example, if a larger heat exchange cavity 310 is required, a flange with a larger thickness is selected, and the specific flange structure is selected according to actual requirements, which is not described herein again.

In a second aspect, another embodiment of the present application also provides a food processor comprising a direct chill tank as described above.

It should be noted that the food preparation machine in this embodiment may be a common ice cream machine, a milkshake machine, a cold and hot drink machine, or other devices with heat exchange requirements, and this embodiment does not limit the present invention.

In the food making machine of the embodiment, the direct cooling cylinder comprises the inner tube and the outer tube, the inner tube is internally provided with an accommodating cavity for loading food, the outer tube is sleeved outside the inner tube, the outer tube and the inner tube are fixedly connected through the connecting part, the outer tube and the inner tube are provided with heat exchange cavities, the upper side and the lower side of the outer tube are respectively provided with the first air guide tube and the second air guide tube, so that a refrigeration source or a heating source enters the heat exchange cavity, the refrigeration source or the heating source is subjected to heat exchange with the inner tube in the heat exchange cavity, the contact area of heat exchange is greatly increased, and the efficiency of heat exchange is improved; simultaneously, first air duct is used for refrigeration source input or heating source output, because the refrigeration source input probably remains the refrigeration oil in first air duct department, and this embodiment provides the structure basis for discharging remaining refrigeration oil from first air duct department through the conversion of air current direction, has effectively prolonged the cycle of equipment maintenance.

The embodiments of the present application have been described in detail with reference to the drawings, but the present application is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present application.
