Introduction to Seafood Cold Storage Solution
Seafood Cold Storage is mainly used for the aquatic food storage(slaughtered fish). The temperature of the seafood is below -20℃ to prevent spoilage. If it does not reach -20℃, the freshness of the seafood will be completely different.
Common temperature ranges for seafood cold storage:
-18~-25℃ freezers, which can be used for the storage of meat, aquatic products, cold drinks, and other foods.
-50~-60℃ ultra-low temperature storage, which can be used for the storage of deep-sea fish, such as tuna.

Working Principle of Seafood Cold Storage
Generally, cold storage is cooled by refrigeration machines, using liquids with very low evaporation temperatures (ammonia or Freon) as coolants. These liquids evaporate under low pressure and mechanical control conditions, absorbing the heat inside the storage room, thereby achieving the purpose of cooling and temperature reduction.
The compression-type refrigerator is very common, which mainly consists of a compressor, condenser, throttle valve, and evaporation pipe. According to the way the evaporation pipe is installed, it can be divided into direct cooling and indirect cooling. Direct cooling installs the evaporation pipe inside the cold storage room, where the liquid coolant directly absorbs the heat inside the room through the evaporation pipe and cools down.Indirect cooling is achieved by a blower that draws the air from the storage room into an air cooling device. The air, after being cooled by the evaporation pipe inside the cooling device, is sent back into the room to reduce the temperature.
The advantage of the air cooling method is that it cools quickly, the temperature in the storage room is more uniform, and it can also remove harmful gases such as carbon dioxide produced during the storage process.
