Most of the frozen cold storage facilities are used in the food industry. The frozen warehouse mainly utilizes the low temperature inside the warehouse to quickly lower the center temperature of the goods to below -15 degrees Celsius, allowing the food to quickly pass through the ice crystal generation zone, thereby ensuring the quality of frozen food to the greatest extent possible.

The structure of quick freezing cold storage is roughly the same as that of ordinary refrigerated storage, with the main difference being that the temperature of quick freezing storage is lower than that of refrigerated storage. Currently, the temperature of quick freezing storage in China is generally below -25 degrees, mostly at -35 degrees, but in some special quick freezing industries (such as tuna quick freezing), the temperature is as low as -50 degrees. A large amount of practice has shown that the lower the freezing temperature of food during the freezing process, the better the quality of frozen food. However, if the temperature of the quick freezing warehouse is set too low, it will inevitably lead to an increase in the cost of the quick freezing cold storage and an increase in operating electricity costs. Therefore, the commonly used quick freezing temperature in China is generally within the above range.

Due to the low temperature of quick freezing cold storage, the insulation material for the storage body of quick freezing cold storage generally uses polyurethane insulation boards with a thickness of over 150mm, while the refrigeration equipment for quick freezing cold storage generally chooses two-stage piston or screw series.

Advantages of quick freezing food processing:

1. Avoid generating large ice crystals between cargo cells, which can affect the structure of food cells.

2. Reducing the loss of juice generated inside the thawed goods greatly increases the value of the food.

3. Quickly reduce the temperature of the goods, thereby quickly killing bacteria and microorganisms and improving storage quality.

What are the advantages of Huixue brand frozen cold storage?

Advanced technology:

The Huixue series cold storage adopts frost free quick freezing refrigeration method, equipped with famous brand compressors and refrigeration accessories, uses automated frost, and the control method has microcomputer intelligent control. The refrigeration system adopts green refrigerant, which is an internationally advanced refrigeration technology in the 21st century.

Innovative materials:

The warehouse body is made of rigid polyurethane or polystyrene foam heat insulation sandwich board, which can be made into various lengths and specifications to meet the different requirements of users by high-pressure foaming process. Its characteristics are: good thermal insulation performance, light weight, high strength, corrosion resistance, aging resistance, and beautiful appearance. The types of cold storage panels include: colored plastic steel, salted steel, stainless steel, embossed aluminum, etc.

Easy to assemble and disassemble:

All the plates and walls of the warehouse body are produced by the unified mold, connected by the internal concave convex groove, which is convenient for assembly, disassembly and transportation, and short for the installation period. The small and medium-sized cold storage can be delivered in 2-5 days. The warehouse body can be combined, separated, enlarged or reduced at will according to the user's needs.

Widely applicable:

The cold storage temperature ranges from+15 ℃ to+8 ℃,+8 ℃ to+2 ℃, and+5 ℃ to -5 ℃, -18 ℃ to -23 ℃, and -25 ℃ to -45 ℃. The lowest temperature can reach -120 ℃ and can achieve dual or multiple temperatures in one warehouse, meeting the needs of different users.
