The storage temperature of cold storage is a key condition that determines the shelf life and quality of goods stored in cold storage. Different categories of stored goods have clear and differentiated requirements for the storage temperature of cold storage. Fresh fruits and vegetables, such as fresh agricultural products, generally require a constant temperature environment of 0 ℃ -10 ℃. This temperature range can inhibit the respiration of fruits and vegetables, reduce the consumption of organic matter, and slow down the rate of spoilage; Frozen livestock, poultry, and aquatic products require a temperature of -18 ℃ or even lower to stabilize the moisture and original nutrients of the ingredients, inhibit microbial activity, and prevent fat oxidation and spoilage; In the field of medicine, vaccines, bioactive reagents and other special storage materials mostly require constant maintenance in an environment of 2 ℃ -8 ℃, and some special biological products need to be stored in ultra-low temperature environments below -20 ℃ for a long time.

There are various types of cold storage, which can be divided into high temperature cold storage, medium temperature cold storage, low temperature cold storage, and ultra-low temperature cold storage according to the temperature range. High temperature cold storage generally maintains a temperature of 0 ℃~10 ℃, suitable for storing fresh ingredients such as fruits, vegetables, dairy products, etc; Medium temperature cold storage is mostly used for storing meat and frozen products, with temperatures ranging from -18 ℃ to 0 ℃; The low-temperature cold storage temperature ranges from -25 ℃ to -18 ℃, suitable for storing seafood and other goods that require long-term preservation; The ultra-low temperature cold storage can reach temperatures below -50 ℃ and is mainly used for storing special pharmaceutical products and high-end deep-sea food ingredients.
