What are the classifications of cold storage? What are the types of cold storage?

Classification of cold storage for cold storage design.

It is classified according to the institutional form, temperature, nature of use, cold processing function, capacity, etc. of cold storage.

1.The design of cold storage is classified according to the structural form of cold storage.

1) Civil cold storage.

In addition to the production of particularly low low temperatures (evaporation temperature below -30), commonly used large-capacity refrigeration units usually use civil cold storage.

Civil cold storage has the characteristics of firmness, good thermal insulation performance, low cost and long construction period. It is mainly composed of reinforced concrete, bricks, moisture-proof layer, thermal insulation layer, floor structure, anti-freeze ventilation structure, etc.

2) Prefabricated cold storage.

The prefabricated cold storage is assembled from prefabricated polyurethane or polystyrene sandwich panels.

3) Jacketed cold storage.

An inner jacket structure is added in the enclosure structure of conventional cold storage, cooling equipment is installed in the jacket, and cold air circulates refrigeration in the jacket, which constitutes a jacketed cold storage. The storage temperature of jacketed cold storage is uniform, the dry consumption of food is small, the external environment has little interference in the warehouse, the air flow resistance in the jacket is small, the airflow organization is uniform, and the cost is higher than that of conventional cold storage.

2.Cold storage design is classified according to the temperature of the cold storage.

1) High temperature cold storage.

It is used for refrigeration of cooled goods, and the warehouse temperature is -2

2) Low temperature cold storage.

It is used for refrigeration of frozen objects, and the warehouse temperature is -10 -30.

3) Ultra-low temperature cold storage.

It is used for tuna and other food refrigeration, and the warehouse temperature is -60.

3.Cold storage design is classified according to the nature of use.

1) Productive cold storage.

Productive cold storage refers to cold storage with cold processing capabilities such as cooling or pre-cooling, freezing, and a certain refrigeration capacity. Productive cold storage is built in the food raw material base or convenient transportation area, and the perishable foods such as fish, meat, poultry, eggs, fruits, vegetables, seafood and quick-frozen pastries are processed and sent to the cold storage or freezing device for cold processing, and then sent to other cold storage for storage and preservation.

2) Distributive cold storage.

Distributive cold storage refers to the cold storage that accepts frozen (or cooled) food and then transports the refrigerated food to the sales link. This kind of cold storage is usually built in large and medium-sized cities or areas with relatively concentrated populations, and has the advantages of large refrigeration capacity, throughput, and long-term storage.

3) Commercial cold storage.

Commercial cold storage refers to the cold storage used for short-term storage of perishable food in commercial and public catering industries.

4.Cold storage design is classified according to cold processing function.

According to the cold processing function, cold storage can be divided into pre-cooling cold storage, fresh-keeping cold storage, frozen cold storage, quick-freezing storage, frozen storage, modified atmosphere storage and so on.

5.Cold storage design is classified according to cold storage capacity.

According to the capacity of refrigerated cold storage, it can be divided into large cold storage, large and medium-sized cold storage, medium-sized cold storage, medium-sized cold storage and small cold storage.

According to the storage temperature, it can be divided into these types:

1. High-temperature small cold storage: mainly used to store fruits and vegetables, eggs, medicinal materials, wood preservation, drying, etc.

The temperature is usually 0 15 and is cooled by blowing air with a air cooler.

2. Medium temperature small cold storage: mainly used to store meat, aquatic products, poultry meat, etc.; The general storage temperature is -15

3. Low-temperature small cold storage: also known as freezing storage, freezing cold storage, freezing of food through air coolers or special freezing devices; The temperature is -18 -25. It is mainly used for quick-frozen food, industrial testing, medical treatment and other special purposes.

4. Quick-frozen small cold storage: quick-frozen cold storage, used for rapid freezing of food.

Classification of cold storage.

1) According to the structural form, cold storage can be divided into: civil cold storage, prefabricated cold storage (active cold storage.

2) According to the nature of use, cold storage can be divided into: production cold storage, distribution cold storage, retail cold storage.

3) According to the size, cold storage can be divided into: large cold storage, medium-sized cold storage, small cold storage (small cold storage.

4) According to the selection of working fluid for cold storage refrigeration equipment, cold storage can be divided into: ammonia cold storage, freon cold storage.

5) According to the requirements of the use of storage temperature, cold storage can be divided into: high temperature cold storage, medium temperature cold storage, low temperature cold storage, ultra-low temperature cold storage, refrigerated cold storage, quick-frozen cold storage.

6) According to the use of structural materials and grades, cold storage can be divided into: high-grade cold storage, low-grade cold storage, FRP cold storage, color steel cold storage, stainless steel cold storage.

7) According to the characteristics of use and storage, cold storage can be divided into: supermarket cold storage, constant temperature cold storage, and modified atmosphere cold storage.

8) According to the storage items, cold storage can be divided into: medicine cold storage, food cold storage, fruit cold storage, vegetable cold storage, tea cold storage, etc.

This Cold Storage Design Code can answer your questions.

The above is a common classification of cold storage types, and the size and nature of the cold storage should be determined before the construction and installation of the cold storage, so as to make the budget accurate.
