It is reported that the temperature of blast freezer is generally - 15 ℃ ~ - 35 ℃. The blast freezer can effectively inhibit respiration, reduce the consumption of organic substances, and maintain the excellent flavor and aroma of fruits and vegetables. Secondly, the blast freezer can restrain the evaporation of water and keep the freshness of fruits and vegetables. Thirdly, the blast freezer can inhibit the breeding of pathogens, control the occurrence of some physiological diseases, and reduce the rate of fruit decay. Finally, it has to be mentioned that the blast freezer can inhibit the activities of some post ripening enzymes, inhibit the production of ethylene, delay the process of ripening and senescence, maintain the firmness of fruits for a long time, and have a long shelf life.
Characteristics of blast freezer:
1. Advanced blast freezer technology:
It adopts frost free quick freezing mode, equipped with famous brand compressor and refrigeration accessories, adopts automatic frost, and the control mode can only be controlled by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the 21st century.
2. The blast freezer material is novel:
The tank body is made of rigid polyurethane or polystyrene foam heat insulation sandwich panel, which is formed by one time pouring with high pressure foaming process, and can be made into various lengths and specifications to meet the different requirements of the users.
Cold storage panel features: good thermal insulation performance, light weight, high strength, corrosion resistance, anti-aging, beautiful appearance.
The types of plate panel of blast freezer: color plastic steel plate, salinized steel plate, stainless steel plate, embossed aluminum, etc.
3. The blast freezer is easy to load and unload：
The wall panel of the blast freezer is all produced by a unified mould. It is connected by internal concave convex slot, and it is convenient to load and unload, and the installation period is short. The small and medium-sized cold storage can be delivered in 2-5 days. The library can be assembled, separated or enlarged or reduced according to the needs of users.
4. Blast freezer is widely used
There are many kinds of temperature in quick-frozen warehouse, and it can realize multi temperature or double temperature in one warehouse to meet the needs of different customers.
