Classification of cold storage 5, what types of cold storage can be divided into?

Cold storage (coldstorage) is the abbreviation of cold storage, mainly for food, dairy products, meat, aquatic products, poultry, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments and instruments to play a constant temperature storage effect. According to different classification methods, cold storage is roughly divided into the following types:

1. According to the scale of cold storage capacity, it is generally divided into large, medium and small

The refrigeration capacity of large-scale cold storage is more than 10,000t;

The refrigeration capacity of medium-sized cold storage is 1000-10000t;

The refrigeration capacity of small cold storage is less than 1000t.

2. According to the design temperature of refrigeration, it is divided into four categories of cold storage: fresh-keeping, low-temperature, quick-frozen and ultra-low temperature

Fresh-keeping cold storage is generally used for fresh food, such as fruits and vegetables, meat and eggs, dairy products, etc., and the temperature is controlled at 0-5;

The refrigeration temperature of low-temperature cold storage is between -25--18, and some foods that need to be frozen can be used in low-temperature cold storage;

The temperature of quick-frozen cold storage is lower, about -30 below, many quick-frozen foods, quick-frozen vegetables and fruits and other foods that need to be frozen quickly, you can use quick-frozen cold storage;

The cold storage with a refrigeration temperature of -45-60 is called ultra-low temperature cold storage, which is generally used for the storage of industrial products, such as some medicines, vaccines, and some seafood and fish.

3. According to the purpose of cold storage, it can be divided into food cold storage, pharmaceutical cold storage and chemical cold storage

Food cold storage is mainly used to store food, keep it fresh and safe;

Pharmaceutical cold storage is used to store drugs and vaccines, maintaining their effectiveness and safety;

Chemical cold storage is used to store chemicals and raw materials, maintaining their stability and safety.

4. According to the refrigeration mode of cold storage, it can be divided into compressor refrigeration cold storage and absorption refrigeration cold storage

The compressor refrigeration cold storage compresses the refrigerant into high-temperature and high-pressure gas through the compressor, and then releases the heat through the condenser heat dissipation, so that the refrigerant becomes a high-pressure liquid, and the refrigeration effect is cooled and evaporated through the expansion valve, so as to achieve the refrigeration effect;

Absorption refrigeration cold storage uses absorbent to absorb and release refrigerant, so as to achieve refrigeration effect.

Water cooling, air cooling refers to the heat dissipation method of the condenser (i.e., the outdoor heat dissipation method) Water cooling - consists of a cooling tower, a cooling water pump and a water-cooled condenser.

Air cooling - composed of a cooling fan and a finned heat exchanger (similar to the outdoor unit of a home air conditioner) Your so-called "380V three-phase electricity with built-in fan and electric furnace wire" refers to the air cooler used in the cold storage to absorb the heat in the warehouse to achieve the purpose of refrigeration. The air cooler consists of: finned heat exchanger, built-in fan and electric heating for defrosting.

Usually the number of electric heating of each air cooler is or 9, the voltage of each demand terminal is 220V, which is uniform load, and the phase line can be connected to R s T three phases on average, and the zero line is connected to zero row. )

Such a dogma! The construction situation is civil engineering and activities, and the temperature is high temperature and low temperature quick-freezing, and I am only talking about civil use.

Standard definition of cold storage:

Cold storage is a storage building complex that uses artificial refrigeration to cool down and has the function of cold insulation, including refrigeration machine room, transformer and distribution room, etc.

1.Wide range of applications.

Cold storage can be applied to both the south and north of China, suitable for the storage of various fruits, vegetables, frozen food (frozen dumplings, frozen fish, cold drinks), flowers, pharmaceutical products and other items;

2.The shelf life is extended and the added value of the product is increased.

Some of the common out-of-season vegetables and fruits on the market are stored in cold storage, which can get good returns for merchants;

3.The construction period is short and easy to use.

In the case of a small cold storage of 10 square meters, it can be completed and put into use in less than a day with full staffing. With the development of cold storage technology, it has been equipped with a microcomputer operation interface. It can clearly understand the operation of the cold storage, and realize remote automatic start and shutdown without special supervision.

Cold storage is mainly used for storing fruits and vegetables, pharmaceutical products, chemical products, quick-frozen food, meat products, etc., and the specific application scenarios are: restaurants, hotels, agricultural cooperatives, agricultural and sideline products companies, hospitals, CDC, chemical plants, flower shops, slaughterhouses, etc.

Cold storage is a kind of refrigeration equipment. Cold storage refers to the use of artificial means to create an environment different from the outdoor temperature or humidity, and is also a constant temperature and humidity storage equipment for food, liquid, chemical, pharmaceutical, vaccine, scientific experiments and other items.

Cold storage is usually located near the port of transport or the place of origin. Compared with refrigerators, cold storage has a larger refrigeration area and has the same refrigeration principle.

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 at 0 15 to the air cooler.

Blow cooling.

2. Medium temperature small cold storage: mainly used to store meat, aquatic products, poultry meat, etc., generally the storage temperature is -15 -18.

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 and other special purposes.

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

In order to solve the cold chain monitoring needs of cold storage at different temperatures, for example, to help pharmaceutical and vaccine companies monitor the real-time monitoring of temperature and humidity of drug reagents in cold storage, Jingchuang cold cloud monitoring and monitoring cloud platform can be used.

The platform is FSP compliant, grabbing offline data from devices for backup analysis; Data missing alarm notification, prevent offline data loss, sound and light alarm prompt + manual background supervision. There are also refrigeration industry engineers, who can remotely set parameters and remotely switch on and off functions, aiming at the misoperation of employees of chain restaurants or fresh cold chain enterprises, resulting in food deterioration or food safety.

accidents, hierarchical alarm mechanism + manual background monitoring, adapt to the comprehensive monitoring scheme of food production enterprises, import and export **, and cold storage in logistics centers to ensure food safety.

Cold storage can be classified according to its purpose of use and the scale of construction.

1.According to the purpose of use, cold storage can be divided into productive cold storage, distribution cold storage and retail cold storage.

Productive cold storage mainly exists in the field of production and processing of food origins, and is used for refrigerated processing, storage and transportation of food.

Distributed cold storage is mainly used for the storage and transportation of food, as well as as as the best channel for the food retail and catering industry.

Retail cold storage is typically located in retail outlets such as supermarkets and convenience stores to store and display food and other products that need to be refrigerated.

2.According to the scale of the building, cold storage can be divided into large cold storage and small cold storage.

Large cold stores are typically used for industrial and commercial purposes, with large storage space and advanced refrigeration equipment to store large quantities of food and other products.

Small cold storages are often used in homes or small commercial establishments, with smaller storage space and simple refrigeration equipment to store small quantities of food and other products.

In addition, according to the temperature control range, cold storage can also be divided into high temperature cold storage, low temperature cold storage and ultra-low temperature cold storage.

The temperature of high-temperature cold storage is usually between 0 and -10 and is mainly used to store food that needs to be refrigerated but still needs to be kept at a certain temperature.

The temperature of low-temperature freezers is usually between -18 and -25 and is mainly used to store food and other products that need to be frozen.

Ultra-low temperature freezers are usually between -30 and -80 and are mainly used to store food and other products that require special ultra-low temperature storage, such as tuna.

In general, different types of cold storage have different purposes of use, building scale and temperature control range, which can be selected and used according to actual needs.

Cold storage is a storage building that uses artificial refrigeration to cool down and has the function of cold insulation, including warehouse, refrigeration machine room, substation and distribution room, etc.

The types of storage include food, medicine, blood, and vaccines.

According to the structural form, it is divided into civil cold storage and prefabricated cold storage.

According to the nature of use, it is divided into productive cold storage and distribution cold storage.

According to the size, it is divided into large-scale cold storage, medium-sized cold storage and small cold storage.
