Differences and characteristics between high temperature cold storage and low temperature cold storage
High temperature cold storage: Constant temperature cold storage, also known as high temperature storage, is mainly used to store fresh eggs, fruits, watercolor, flowers, Chinese herbal medicine, high-grade furniture and clothing and other commodities. The storage varieties are different, and the room temperature is different, generally between 0-4 ℃. The refrigeration equipment adopts air cooler, which is installed in the center of one end of the warehouse, and adopts multi nozzle air duct for uniform air supply There is still respiratory function in storage, so in addition to maintaining appropriate temperature and humidity conditions, appropriate fresh air (outdoor fresh air) should be introduced. If chilled meat is stored, the storage period should not exceed 14-20 days.
Low temperature cold storage: Quick frozen cold storage, also known as low temperature storage. For the storage of frozen food, the storage temperature standard is - 35 ℃ - 18 ℃, the freezing storage temperature of general meat is - 25 ℃ - 18 ℃, and the storage temperature of seafood products is - 30 ℃ - 20 ℃. The storage temperature of ice cream products is - 30 ℃ - 23 ℃. Lower than - 40 ℃ for some seafood. For example, the temperature in cold storage room is - 50 ℃.
In addition to their different temperature and storage purposes, the requirements for engineering accessories of high-temperature cold storage and low-temperature cold storage are also different. For example, in terms of refrigeration compressor, ordinary brand compressor can also meet the needs of general constant temperature cold storage, but for low-temperature cold storage, the temperature requirement is lower, and the performance and quality requirements are higher. Generally, the compressor of international big brand is used However, on the other hand, the price is the difference. Under the same conditions, the lower the temperature of the cold storage, the greater the cost of accessories, energy consumption and other aspects, the higher the price.
