TECHNICAL FIELD

[0001] The present application relates to the field of ice storage, in particular to a broiler processing and preservation ice storage. BACKGROUND

[0002] Freezer can be used for food, medicine and other goods storage, due to the storage requirements and processing requirements of goods (for example, the temperature of acid removal and segmentation processing is generally 4-12 degrees Celsius, while the temperature of rapid cooling (-1~0℃), rapid freezing (-30~40℃) and long-term storage (-18~-25 degrees Celsius), in order to improve the utilization rate of cold, the freezer is often divided into different cold rooms and ice storages to store different types and different processing sections of goods.

[0003] The bottom of the ice storage is easy to produce thick ice layer due to water vapor condensation, which needs to be cleaned regularly to avoid its spread, the common method in the art is to heat or mechanically remove, using heating method to melt the ice layer has good cleaning effect and is not easy to have ice layer residue, however, heat is easy to cause local temperature imbalance in the freezer; and the mechanical removal method is easy to have ice layer residue, and the machine is easy to scratch the surface of the ice storage, the purpose of the present application is to provide a new ice storage structure to solve the above technical problems. SUMMARY

[0004] The purpose of the present application is to provide a broiler processing and preservation ice storage to solve the problems mentioned in the background.

[0005] To achieve the above purpose, the present application provides the following technical scheme: including ice storage main body, cavity, vortex tube, air compressor, pressure tank and exhaust pipe, the ice storage main body is used for storing frozen goods, and the air compressor and the pressure tank are located outside the freezer, the cavity is arranged on the bottom surface of the ice storage main body, the cavity is distributed with pipe bodies at equal intervals, and the inside of the cavity is vacuumized, the purpose of vacuumizing is to reduce heat loss and ensure that the heat of hot air is concentrated on the pipe body and dispersed along the pipe body, the dispersed heat is used to cause local melting of the ice layer, and the ice layer is divided into grids, which is helpful for subsequent peeling of the ice layer, one end of the pipe body is sealed, the hot gas outlet of the vortex tube is connected with the pipe body, the cold gas outlet of the vortex tube is communicated with the outside of the ice storage main body, the cold gas generated during the operation of the vortex tube can be discharged to the freezer to supplement the cold energy and avoid temperature imbalance of the freezer, the pressure tank is communicated with the air compressor, and the pressure tank is used for storing the pressurized gas pumped by the air compressor, the pressure tank is communicated with the gas inlet end of the vortex tube through the pipeline with the first electromagnetic valve, the flow of the pressurized gas through the vortex tube is adjusted by controlling the first electromagnetic valve, and the exhaust pipe is communicated with the gas inlet end of the vortex tube through the pipeline with the second electromagnetic valve, in specific implementation, the tail end of the exhaust pipe is connected with the air extraction equipment such as fan and air pump located outside the freezer for discharging the hot air in the pipeline.

[0006] To optimize the above technical scheme, further measures are taken: the deicing device includes a nitrogen gas spring, a cone, a first metal sheet, a second metal sheet and a third metal sheet, the nitrogen gas spring is vertically arranged in the pipe body, the pipe body and the cavity are provided with openings matched with the position of the nitrogen gas spring, the cone is arranged at the bottom end of the nitrogen gas spring, the first metal sheet, the second metal sheet and the third metal sheet are sequentially arranged above the nitrogen gas spring above the cone, the first metal sheet, the second metal sheet and the third metal sheet are respectively provided with a first through hole, a second through hole and a third through hole, the first metal sheet and the third metal sheet are of thermal bimetallic material, the first through hole and the second through hole are staggered without communication, the second through hole and the third through hole are staggered without communication, the terms "first" and "second" are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first" and "second" can be explicitly or implicitly included one or more features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0007] Thermal bimetal refers to a kind of metal (or alloy) composed of two layers with different thermal expansion coefficients in the prior art. The layer with large thermal expansion coefficient is the active layer, and the layer with small thermal expansion coefficient is the passive layer. When the thermal bimetal is heated, the length of the active layer expands freely more than the passive layer, but because the two layers are firmly combined together, the thermal bimetal bends into an arc shape, and when it cools down, it is the opposite. The specific material of the thermal bimetal is not a necessary technical feature and is not the technical content that the applicant wants to protect, so it will not be further explained and described. The person skilled in the art can change the response temperature and bending degree of the thermal bimetal by changing the composition, specification and thickness of the thermal bimetal in specific implementation.

[0008] Nitrogen gas spring refers to an elastic component filled with gas inside in the prior art, which belongs to the prior art content known to those skilled in the art, so its specific structure and working principle will not be further explained and described. The elastic coefficient of the nitrogen gas spring can be adjusted by changing the model and specification of the nitrogen gas spring.

[0009] As a further improvement of the above technical scheme: the active layer of the first metal sheet is adjacent to the second metal sheet, and the passive layer is adjacent to the cone. The intention of such design is to ensure that when the first metal sheet is heated by hot air acting on it, the first metal sheet can bend towards the ice layer, and the ice layer is separated from the bottom surface of the cavity by the first metal sheet pushing the ice layer outward.

[0010] As a further improvement to the technical solution: the active layer of the third metal sheet is adjacent to the second metal sheet, and the passive layer is adjacent to the cavity. This design is intended to ensure that when hot air acts on the third metal sheet and heats it up, the third metal sheet can bend towards the cavity, creating a gap between the ice layer and the cavity. This helps the hot air to penetrate the gap, ensuring that the ice layer can peel off completely from the cavity surface and reducing ice layer residue.

[0011] As an improvement to the aforementioned technical solution: the area of ​​the third metal sheet is larger than that of the first metal sheet, and the area of ​​the second metal sheet can cover the opening, ensuring that hot air can fully contact the third metal sheet before it bends and deforms, preventing hot air from escaping from the gap between the third metal sheet and the opening, and also preventing ice layer from entering the pipe body through the opening when idle.

[0012] Furthermore, there is a deformation joint between the cone and the first metal sheet, and a rubber ring is installed in the deformation joint. The purpose of the deformation joint is to provide bending deformation space for the first metal sheet, while the rubber ring can prevent the ice layer from entering the deformation joint.

[0013] Furthermore, it also includes an electric heating wire, which is wound around the surface of the pipe connecting the pressure tank and the vortex tube, and the pipe is covered with insulation material covering the heating wire. Specifically, it refers to a device in the prior art that can generate heat when energized. The electric heating wire is prior art and is known to those skilled in the art, so its specific structure and working principle will not be further explained. Its purpose is to prevent the pressurized air from being cooled due to the low temperature of the pipe, which would cause a drop in pressure. At the same time, it can also increase the temperature of the pressurized air and ensure the heating effect of the hot air on the de-icing device.

[0014] Furthermore, the cavity surface is coated with a polytetrafluoroethylene (PTFE) coating. PTFE has excellent chemical corrosion resistance and an extremely low surface friction coefficient. Its purpose is to reduce the adhesion between the ice layer and the cavity surface, thereby reducing the adhesion of the ice layer, while also facilitating the penetration of hot air into the gap between the ice layer and the cavity.

[0015] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: A. By using pressurized gas to drive the vortex tube to generate hot and cold air, the hot air is used to separate the ice layer and the cold air is used to compensate for the cold load, which can avoid local temperature imbalance in the cold storage and help the internal temperature to quickly return to balance. B. The pipe is filled with hot air, causing the ice layer to melt locally and form compartments. Subsequently, the hot air, in conjunction with the de-icing device, can separate and break up the ice layer, resulting in a good ice layer separation effect. C. The de-icing device, in conjunction with hot air, can create a gap between the ice layer and the cavity surface. The hot air enters the gap and causes localized melting, which helps the ice layer to separate from the cavity surface, leaving less ice residue. Attached Figure Description

The first metal sheet 703, the second metal sheet 704, and the third metal sheet 705 are respectively provided with a first through hole 707, a second through hole 708, and a third through hole 709. The first metal sheet 703 and the third metal sheet 705 are made of thermoplastic bimetallic material. A deformation joint 7010 exists between the cone 702 and the first metal sheet 703. A rubber ring 7011 is provided inside. The active layer of the first metal sheet 703 is adjacent to the second metal sheet 704. The active layer of the third metal sheet 705 is adjacent to the second metal sheet 704. The passive layer is adjacent to the cavity 200 and the cone 702.

The area of ​​the third metal sheet 705 is larger than the areas of the first metal sheet 703 and the second metal sheet 704 and can cover the opening 706.

[0023] Working principle: In Example 1, the air compressor 400 generates pressurized gas, which is stored in the pressure tank 500. When cleaning the ice layer, the first solenoid valve 501 releases the pressurized gas, which enters the vortex tube 300. The hot gas leaves from the hot gas outlet of the vortex tube 300 and enters the tube body 201, heating the tube body 201. The heated tube body 201 causes the ice layer attached to the bottom surface of the cavity 200 to be distributed along the tube body 201 through heat conduction, resulting in local melting. This helps the ice layer to separate from the cavity 200, achieving the purpose of cleaning the ice layer. During the process, the cold gas leaves from the cold gas outlet of the vortex tube 300 and is discharged into the cold storage, compensating for the cold storage temperature to avoid local temperature imbalance. After the ice layer is removed from the surface of the cavity 200, the first solenoid valve 501 closes and the second solenoid valve 601 opens. The remaining hot gas in the tube body 201 is discharged from the exhaust pipe 600 through the external air extraction equipment, reducing the cold loss in the cold storage.

[0024] In Example 2, the air compressor 400 generates pressurized gas, which is stored in the pressure tank 500. When clearing the ice layer, the first solenoid valve 501 releases the pressurized gas, allowing it to enter the vortex tube 300. Subsequently, hot gas enters the tube body 201 from the hot gas outlet of the vortex tube 300 and heats the tube body 201. The heated tube body 201 causes the ice layer attached to the bottom surface of the cavity 200 to partially melt along the tube body 201 through heat conduction. During this process, the third metal sheet 705 comes into contact with the hot air and gradually heats up.

[0025] After heating, the third metal sheet 705 bends and deforms. The bent third metal sheet 705 stretches the nitrogen spring 701, causing the cone 702 to press against the ice layer outwards, which helps to create a gap between the ice layer and the surface of the cavity 200. At the same time, after the third metal sheet 705 bends, hot air can enter the gap through the third through hole 709. The hot air in the gap can heat the ice layer, which helps to separate the ice layer from the surface of the cavity 200. After the third metal sheet 705 bends and deforms, the hot air can act on the second metal sheet 704 through the third through hole 709. After the second metal sheet 704 heats up, it can drive the first metal sheet 703 to heat up and bend and deform due to heat conduction. The bent and deformed first metal sheet 703 can push the ice layer, causing the ice layer to separate from the surface of the cavity 200. At the same time, the hot air can act on the ice layer around the cone 702 through the first through hole 707, causing its inner side to melt, which helps the cone 702 to penetrate the ice layer and crack it. During the above process, cold air leaves from the cold air outlet of the vortex tube 300 and is discharged into the cold storage to compensate for the cold storage temperature and avoid local temperature imbalance. After the ice layer is completed from the surface of the cavity 200, the first solenoid valve 501 is closed and the second solenoid valve 601 is opened. The hot air remaining in the tube 201 is discharged from the exhaust pipe 600 through the external air extraction equipment to reduce the cold loss in the cold storage.

[0026] In this invention, the control of each electrical component is achieved through an external controller. The controller's control circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
