Cold storage is usually divided into four temperatures: high temperature, medium and low temperature, low temperature, and ultra-low temperature. Different ingredients require different temperatures.

A. High temperature cold storage
The high temperature cold storage is what we call the cold storage cold storage. Adhere to the temperature is usually around 0 ° C, and air cooler unit with a cooling fan.

B. Medium and low temperature cold storage
The medium and low temperature cold storage is the high temperature freezing cold storage, the temperature is usually within -18°C, and it is mainly used to store meat, water commodities and commodities suitable for this temperature range.

C, low temperature cold storage
Low-temperature cold storage, also known as freezing storage, freezing cold storage, usually the storage temperature is about -20°C~-30°C, and the freezing of food is completed by air cooler or special freezing equipment.

D. Ultra-low temperature cold storage
Ultra-low temperature cold storage, ≤-30 °C cold storage, is mainly used for quick-frozen food and special purposes such as industrial experiments and medical treatment. Compared with the above three, the applications on the market need to be slightly smaller.
