Description

Technical Field

[0001] This invention relates to the field of ice storage, and in particular to an ice storage facility for processing and preserving broiler chickens. Background Technology

[0002] Cold storage facilities can be used to store food, medicine and other items. Due to the different storage and processing requirements of the items (for example, the temperature for acid removal and cutting processing is generally 4-12 degrees Celsius, while rapid cooling (-1 to 0 degrees Celsius), rapid freezing (-30 to 40 degrees Celsius) and long-term storage (-18 to -25 degrees Celsius) are required), in order to improve the utilization rate of cold energy, cold storage facilities are often divided into different cold rooms and ice rooms to store different types of items and different processing stages.

[0003] Thick ice layers easily form at the bottom of ice storage facilities due to water vapor condensation. These ice layers need to be cleaned regularly to prevent their spread. Common methods in the field are heating or mechanical removal. Heating melts the ice layer, which is effective in cleaning the ice layer and leaves little residue. However, the heat can easily cause local temperature imbalances inside the cold storage facility. Mechanical removal, on the other hand, is prone to leaving ice residue and can easily scratch the surface of the ice storage facility. The purpose of this invention is to propose a new ice storage structure to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cold storage for broiler processing and preservation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: It includes an ice storage body, a cavity, a vortex tube, an air compressor, a pressure tank, and an exhaust pipe. The ice storage body is used to store frozen products, and the air compressor and pressure tank are located outside the ice storage. The cavity is located on the bottom surface of the ice storage body. Tubes are evenly distributed within the cavity, and the cavity is evacuated. The purpose of evacuation is to reduce heat loss and ensure that the heat of the hot air is concentrated on the tubes and dissipates along them. This dissipated heat causes localized melting of the ice layer. Dividing the ice layer into sections facilitates the subsequent gradual peeling off of the ice layer. One end of each tube is sealed, and the hot air outlet of the vortex tube is connected to the tube. The cold air outlet of the vortex tube is connected to the outside of the main body of the ice storage. The cold air generated by the vortex tube during operation can be discharged to the cold storage to supplement the cold capacity and avoid temperature imbalance in the cold storage. The pressure tank is connected to the air compressor and is used to store the pressurized gas pumped out by the air compressor. The pressure tank is connected to the air inlet of the vortex tube through a pipe with a first solenoid valve. The flow rate of the pressurized gas through the vortex tube is adjusted by controlling the first solenoid valve. The exhaust pipe is connected to the air inlet of the vortex tube through a pipe with a second solenoid valve. In a specific implementation, the end of the exhaust pipe is connected to an air extraction device such as a fan or air pump located outside the cold storage to exhaust the hot air in the pipe.

[0006] To optimize the above technical solution, further measures are taken, including a de-icing device comprising a nitrogen spring, a cone, a first metal plate, a second metal plate, and a third metal plate. The nitrogen spring is vertically mounted inside the tube, and openings matching the position of the nitrogen spring are provided on the tube and the cavity. The cone is located at the bottom of the nitrogen spring. The first, second, and third metal plates are sequentially mounted on the nitrogen spring above the cone. The first, second, and third metal plates are respectively provided with a first through hole, a second through hole, and a third through hole. The first and third metal plates are made of a thermoplastic bimetallic material. The first and second through holes are staggered and not connected, and the second and third through holes are staggered and not connected. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0007] Thermal bimetal refers to a technology in which two layers of metals (or alloys) with different coefficients of thermal expansion are formed. The layer with the larger coefficient of expansion is called the active layer, and the layer with the smaller coefficient of expansion is called the passive layer. When heated, the active layer expands more freely than the passive layer. However, because the two layers are firmly bonded together, the thermal bimetal bends into an arc shape. The opposite occurs when it cools. The specific material of the thermal bimetal is not a necessary technical feature nor is it the technical content that the applicant seeks to protect. Therefore, it will not be further explained. In practice, those skilled in the art can change the response temperature and bending degree of the thermal bimetal by changing its composition, specifications, and thickness.

[0008] A nitrogen spring refers to an elastic component that is internally filled with gas in the prior art. Since it is prior art and known to those skilled in the art, its specific structure and working principle will not be further explained. Its elastic coefficient can be adjusted by changing the model and specifications of the nitrogen spring.

[0009] As a further improvement to the above technical solution: the first metal sheet active layer is adjacent to the second metal sheet, and the first metal sheet passive layer is adjacent to the cone. The purpose of this design is to ensure that when hot air acts on the first metal sheet to heat up the first metal sheet, the first metal sheet can bend towards the ice layer, and the ice layer is pushed outward by the first metal sheet to ensure that the ice layer is separated from the bottom surface of the cavity.

[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 of the third metal sheet is adjacent to the cavity. The purpose of this design is to ensure that when hot air acts on the third metal sheet and heats up the third metal sheet, the third metal sheet can bend towards the cavity, so that a gap is created 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 third metal sheet is larger than that of the second metal sheet, 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, a deformation joint exists between the cone and the first metal sheet, and a rubber ring is installed inside 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 ice layer from invading 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 strength 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:

[0016] 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.

[0017] 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.

[0018] 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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] In this invention, the control of each electrical component is achieved through an external controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field.
