Which types of cold storage

Which types of cold storage, we have a lot of food is in need of refrigeration, so a lot of places have a cold storage, cold storage is the cold chain system in the renewal of the initial product temperature after a sharp drop in the ring, but also low-temperature products in the cold chain system to stay in the stronghold for the longest time, so which types of cold storage it?

Which types of cold storage1

Classification of cold storage

Cold storage is a part of the cold chain system after the renewal of the initial product temperature dropped sharply, but also low-temperature products in the cold chain system to stay in the stronghold of the longest time, so the quality of the product requirements in the management of the logistics of the low-temperature occupies an important position.

Cold storage is roughly divided into two categories: refrigerated warehouses to store fruits and vegetables, fresh fish, fish eggs, eggs, fresh milk, fruit juice, etc., and frozen warehouses to store meat, ice cream, etc., mainly.

First, according to the temperature division of cold storage based on the temperature of the warehouse different classifications, divided into refrigerated warehouses, frozen warehouses, special refrigerated warehouses,

① refrigerated warehouses, wherever the temperature is maintained in the product freezing temperature above the frozen warehouses belonging to cold storage, the general freezing point of fresh food is mostly in the first 2 ℃ above the freezing point of the various types of products due to the nature of the different, the temperature is also different, most of the temperature is about the temperature in the refrigerated warehouse, the temperature is about the temperature in the refrigerated warehouse. Differences, most of the library temperature is about 4 ℃ below.

② freezer where the product temperature is maintained at the freezing temperature below the frozen warehouse, such as long-term frozen storage of frozen fish or meat, frozen food, etc., the temperature of the warehouse is about a 23 ℃ below.

③ special cold storage where the need to simultaneously control the temperature and humidity of the warehouse are special cold storage, such as fresh fruits and vegetables cold storage.

Second, according to the purpose of the cold storage division

① production cold storage for food processing enterprises is an important part of the main construction of food production near the source of the more concentrated areas. Fish, meat, poultry, eggs, fruits, vegetables and other perishable food, after appropriate processing, sent to the cold storage for cold processing, and then transported to the sales area.

It is characterized by a large cold processing capacity, while equipped with a certain capacity of refrigerated tonnage for turnover. Food circulation is characterized by zero in and out. Its cold storage capacity is determined by the cooling and freezing capacity and transportation conditions. As a large number of raw materials and finished products need to be transferred, it is required to be built in a place with convenient transportation.

② circulation cold storage is mainly to receive cold processed food, generally built in large and medium-sized cities, densely populated industrial and mining areas and land and water transportation hubs, as the market supply, transportation transit and storage of food.

It is characterized by a large refrigerated capacity, freezing capacity is small, but also to consider a variety of food storage. The characteristics of food circulation with the function of cold storage is different. Due to the large amount of cold storage, in and out of the goods are more concentrated, so the requirements of its transportation smooth, rapid throughput.

Temperature varies with the use of different requirements.

Third, according to the length of the storage period is divided into storage type library and circulation type library.

Fourth, according to the construction method is divided into civil library and assembly library. The civil library can be divided into single-story library, multi-story library and three-dimensional automatic cold storage.

Fifth, according to the storage mode can be divided into mechanical refrigeration storage and air-conditioning storage

Fourth, according to the storage of goods to distinguish

0 ℃ above the appropriate storage of fruits and vegetables, meat, mushrooms, green plants, electronic raw materials, flowers, beverages, beer and other food preservation.

0 ℃ below is suitable for storage of aquatic seafood, ice cream, meat refrigeration, medicine, chemicals and other items refrigerated.

-20 ℃ below suitable for storage of meat, fish, seafood, medicine, chemicals and other items frozen.

Fifth, according to the functionality of the distinction

can be divided into fresh storage, pre-cooling library acid-expelling library, quick-freezing library, gas-conditioning library, etc., for example: vegetable fresh storage, vegetable pre-cooling library, pork acid-expelling pre-cooling library, meat quick-freezing library and many other types.
