Cold storage has become one of the indispensable equipment in the goods turnover, storage and sales of cold chain enterprises such as fresh food. It plays an increasingly important role in quality assurance and plays an important role in promoting the value of goods and economic value. Of course, according to different standards, there are many types of cold storage. What are the most common types of cold storage in cold storage installation?
Air-conditioned cold storage
The air-conditioned cold storage is a special type of cold storage, because it not only realizes the low-temperature environment of the warehouse, but also realizes the gas environment of the warehouse. To put it simply, the air-conditioned cold storage is to add a gas composition regulation system on the basis of the fresh-keeping cold storage, so as to control the temperature, humidity, carbon dioxide, oxygen concentration, ethylene concentration and other conditions in the storage environment to inhibit the respiration of fruits and vegetables and delay their metabolism process. Therefore, the cost of air-conditioned refrigerators is relatively high, which are mainly used to keep fresh high-value fruits and vegetables, such as kiwi, pear, etc. Relevant data show that the storage period of fruits and vegetables can be extended by 0.5~1 times or more in CA cold storage than in fresh storage cold storage, and the freshness and marketability can be better guaranteed.
Cold storage
The temperature of the cold storage is usually – 15 ℃~18 ℃, which is mainly used to refrigerate meat and aquatic products, such as supermarkets, frozen goods markets, etc. It is also the most common type of cold storage in the projects undertaken by HEGERLS. It is a general feature of this type of cold storage to store and pick up goods on demand from time to time.
Fresh keeping cold storage
The temperature of the cold storage is usually 0 ℃~5 ℃, which is mainly used to preserve fruits and vegetables. The appropriate and stable low temperature environment slows down the metabolism of agricultural products such as fruits and vegetables, and reduces the loss of nutrients, so that the original quality and freshness of agricultural products can be largely maintained in a long period of refrigeration. In the circulation links such as fruit and vegetable planting, transportation, storage and sales, the fresh-keeping cold storage has become one of the important necessary hardware facilities for quality assurance.
Freezer
The temperature of the freezer is usually – 22 ℃~- 25 ℃, which is lower than that of the refrigerator. It is mainly used for the long-term preservation of seafood, ice cream and other frozen dairy products. Like the refrigeration principle of fresh storage and cold storage, the cold storage also uses various refrigeration equipment to keep the room at a certain low temperature. Many foods, such as ice cream, will lose their fragrance if they do not reach – 25 ℃ during storage; When seafood is stored below – 25 ℃, its freshness and taste are much worse. Therefore, what Haigris should remind us is that for customers who want to build a cold storage or a freezer, the temperature of the cold storage must be determined according to the goods stored, and then the configuration and scheme design of the cold storage equipment must be carried out.
In general, these are the four most common types of cold storage, which are also the most manufactured cold storage types in the projects undertaken by HEGERLS, and are the most widely used large, medium and small cold storage by its major enterprises. In fact, the type of cold storage is not only that, but also more extensive, and all kinds of cold storage have their own unique structure, storage capacity, refrigeration system, regulation and other characteristics. Next, HEGERLS will introduce the diversified forms of cold storage types for the extended development of large enterprises, so that large, medium and small enterprises can better choose the type of cold storage suitable for their own enterprises after they understand the cold storage to a certain extent.
Cold storage is classified according to its capacity and scale, including the following types:
It can be divided into large cold storage, medium cold storage and small cold storage.
Large cold storage: cold storage capacity is more than 10000 tons;
Medium cold storage: cold storage capacity of 1000~10000 tons;
Small cold storage: Refrigeration capacity is below 0-1000 tons.
The cold storage is classified according to the design temperature, and the specific types are as follows:
It can be divided into high-temperature warehouse, Chinese warehouse, low-temperature warehouse and ultra-low temperature warehouse.
High temperature warehouse: also known as constant temperature warehouse, with design temperature of 5-15 ℃;
Medium temperature warehouse: also known as cold storage, with design temperature of 5~- 5 ℃;
Low temperature storage: also known as freezer, with design temperature of – 18~- 25 ℃;
Quick freezing warehouse: also known as quick freezing warehouse, with design temperature of – 35~- 40 ℃;
Ultra low temperature storage: also known as deep cold storage, with a design temperature of – 45~- 60 ℃.
The cold storage is divided into the following types according to the nature of use:
It can be divided into production cold storage, distribution cold storage and retail cold storage.
Productive cold storage: cold storage places with large refrigeration processing capacity and certain cold storage capacity, such as meat joint processing plant, dairy joint processing plant, etc;
Distributive cold storage: also known as transit cold storage, which is used to receive and store frozen processed food. The production characteristics of this type of cold storage are whole in and zero out or whole in and whole out. It has a certain refreezing capacity and can meet the need of necessary refreezing of food. In addition, its site selection is often land and water transport hubs, large and medium-sized cities, and industrial and mining areas with large populations;
Retail cold storage: refers to the cold storage built in industrial and mining enterprises or urban large non-staple food stores and vegetable markets for temporary storage of retail food. Its characteristics are small storage capacity, short storage period, and its storage temperature varies with different use requirements; In the structure of the warehouse body, most of them use assembly type combined cold storage.
After the cold storage is classified according to its storage items, its types are as follows:
Medical cold storage: cold storage that can keep medical supplies from deterioration and failure under low temperature cold storage conditions, extend the shelf life of medical supplies, and meet the technical requirements of the Medical Supervision Bureau;
Meat cold storage: it is used to keep low temperature in the warehouse by manual refrigeration, and is suitable for buildings where meat is frozen and refrigerated;
Fruit cold storage: There are two types of cold storage: fruit preservation storage and controlled atmosphere storage. Low temperature or increase of equipment to control the content of oxygen, carbon dioxide and other gases in the storage to inhibit the activity of microorganisms and enzymes, thus prolonging the storage time of fruits, which is very suitable for the storage and processing of most fruits;
Vegetable cold storage: It is not much different from fruit cold storage, and it is also often divided into vegetable fresh storage and controlled atmosphere storage. Low temperature or increased equipment is used to control the content of oxygen, carbon dioxide and other gases in the storage to inhibit the activity of microorganisms and enzymes, thus prolonging the storage time of vegetables, which is very suitable for the storage and processing of most vegetables;
Cold storage of aquatic products: It is often used for the freezing storage of aquatic products, fish and seafood to extend the shelf life of seafood and maintain the original flavor of seafood. (At present, from the perspective of the development trend of the cold chain industry, small and medium-sized controlled atmosphere warehouses for fruits and vegetables are deeply loved by fruit farmers and sellers. Based on the conventional cold storage, the technology of controlled atmosphere warehouses has further extended the fresh-keeping time.)
