Classification of cold room

1.By structural features

① civil construction type cold storages  The main structure of this type of cold storage (the support of the warehouse dwelling, beams, roof, floor slab) and the underground load structure are all made of reinforced concrete, and the walls of the enclosure structure are made of brick. Old-style cold storage in the insulation material to rice husk, cork and other adobe structure; new-style insulation material for polyurethane spray foam and made, the way will generally be around the enclosure insulation layer on the exterior of the protective layer to prevent the insulation layer is destroyed,common have color steel plate and bamboo piece, bamboo piece way does not have waterproof function.

②Assembly Cold Store The main structure (columns, beams and roofs) of these cold rooms is generally made of light steel, and the walls of the envelope are assembled using prefabricated composite insulation panels. The insulation is made of rigid polyurethane foam, rigid polystyrene foam, etc. Of course, many customers use prefabricated panels to form the body of the cold store, even though the envelope is in the form of civil engineering.

2.By nature of use

①Production cold storage Mainly built near food production areas, areas with a high concentration of supplies and fishing bases, usually as an important part of aquatic processing plants, meat processing plants, poultry and egg processing plants, dairy processing plants, fruit and vegetable processing plants, all kinds of food processing enterprises. The food products are stored briefly after cold processing and then transported to various sales areas for sale or long-term storage. Such cold storage is equipped with a large cooling and freezing capacity and a certain storage capacity.

②Distributive cold storage Mainly located in large and medium-sized cities or areas with a large and concentrated population, the main role is to receive cold-processed food products for storage and market supply. It is characterised by a large cold storage capacity, which enables multiple foodstuffs to be stored; a small freezing capacity, which is only used for the re-freezing of softened portions of long-distance transfer goods in transit and the freezing of small batches of local fresh foodstuffs. It therefore requires good transport conditions in the storage area and rapid throughput.

③Retail Cold Storage   This type of cold storage is generally built near large living facilities, such as large food markets and supermarkets, for the temporary storage of retail food. It is characterised by small storage capacity, short storage period and varying temperatures with different requirements.

3.By size

The distinction between cold storage according to size is a relative concept, the general distinction is: 10,000 tons of cold storage is called large cold storage, production cold storage equipped with freezing capacity in the range of 120 ` 160t/d, distribution cold storage equipped with freezing capacity in the range of 40 ~ 80t/d; 1,000 tons to 10,000 tons level for medium-sized cold storage, production cold storage equipped with freezing capacity in the range of 40 ` 120t/d, distribution cold storage equipped with freezing capacity in the range of 20 ~ 60t/d The production cold stores are equipped with a freezing capacity in the range of 20 to 60t/d, the distribution cold stores are equipped with a freezing capacity in the range of 20 to 40t/d, the distribution cold stores are equipped with a freezing capacity in the range of 20t/d and the retail cold stores are generally not equipped with a freezing store.

4.By temperature

①Cooling room also known as high temperature storage, storage temperature is generally controlled above the freezing temperature of food juices, commonly used in the preservation of vegetables and fruits or processed cold storage cooling before freezing, often using chillers blowing air form.

②Freezer, also known as quick-freeze, generally at temperatures below -20°C, through chillers or special freezing devices to achieve the freezing of food processing, commonly used in the freezing and processing of aquatic products, animal meat and poultry.

③Refrigerated warehouse that stores cooled or frozen food cold storage. The temperature of the cold storage room for cooled food is often set at 2~4℃, commonly used for frozen vegetables and fruits and dairy and egg food; the temperature of the cold storage room for frozen food is often set at -12-18℃ (the temperature of the cold storage room for frozen tuna is set at -30℃).

In addition, there are also different refrigerants to classify the cold storage, but also according to the different forms of heat transfer equipment to distinguish the cold storage category
