[0002] Cryopreservation is a process necessary to maintain the integrity of biological materials during long-term storage. At sufficiently low temperatures, all chemical processes and biological functions of such materials are effectively stopped, allowing them to be safely stored for almost any length of time.

[0023] During operation, the worker places the industrial product on the top of the heat-resistant pallet 66. The industrial product drives the heat-resistant pallet 66 downward due to the influence of gravity. The heat-resistant pallet 66 drives the first pneumatic telescopic rod 65 to contract and inputs the internal gas of the heat-resistant pallet 66 into the second pneumatic telescopic rod 67 through the clamping pallet 64. The second pneumatic telescopic rod 67 is extended. The second pneumatic telescopic rod 67 drives the heat-resistant clamping plate 68 to move to the industrial product to clamp and fix it. When an industrial product is placed on a clamping pallet 64, the drive motor 60 is started. The drive motor 60 is connected to the heat-resistant clamping plate 68 through the transmission shaft 62. The clamping plate 64 drives the industrial products to rotate, and the staff can place the industrial products on the surface of the new heat-resistant plate 66, without the need for the staff to manually rotate the clamping plate 64. When the industrial products are placed, the refrigeration mechanism 5 is started to cool the industrial products. The driving motor 60 drives the industrial products to rotate through the transmission shaft 62 and the clamping plate 64, so that the cooling effect on the industrial products is more uniform. The setting of the limit spring 71 prevents the ice scraped by the scrubbing mechanism 7 from entering the driving motor 60 and causing damage to it, thereby improving the practicality of the device. After the industrial product is clamped by the clamping mechanism 6, the compressor 50 is started, and the compressor 50 compresses the coolant and inputs it into the condenser 51. The condenser 51 cools the coolant while transporting it. The condenser 51 inputs the internal coolant into the filter 54 through the transmission plate 52 and the capillary connecting tube 53. The filter 54 filters the coolant to prevent it from subsequently entering the evaporation tank 56 and causing damage to it. The coolant in the filter 54 enters the evaporation tube 55 to freeze and cool the industrial product in the freezing and low-temperature box 2. The coolant in the evaporation tube 55 enters the evaporation tank 56 to prevent the industrial product in the freezing and low-temperature box 2 from being too hot and causing the coolant to not completely absorb heat and liquefy and enter the compressor 50 and cause damage to it. When the transmission shaft 62 rotates, the transmission shaft 62 drives the ice-cleaning soft brush 73 to rotate through the first telescopic rod 72 to clean the ice on the side wall of the evaporator tube 55, so as to prevent too much ice from adhering to the side wall of the evaporator tube 55 and affecting its cooling effect on the industrial products inside the freezer 2. The ice scraped off by the ice-cleaning soft brush 73 cools the drive motor 60 to prevent it from being damaged by excessive temperature. The melted ice enters the cooling bin 74 through the drip hole 75, and the cooling bin 74 cools the condenser tube 51 to improve the cooling efficiency of the condenser tube 51. When the water temperature inside the cooling bin 74 reaches a certain temperature, the temperature-sensing spring 78 is extended, and the temperature-sensing spring 78 drives the sealing slide plate 791 to extend to the inside of the drain pipe 76, and the water inside the cooling bin 74 is discharged through the drain pipe 76.
