What is quick-frozen food cold storage?
Quick-frozen cold storage is a method by which food rapidly passes through its larger ice crystal formation zone and rapidly freezes when the average temperature reaches -18℃.
The quick-frozen storage is mainly used for the low temperature freezing of food, medicine, medicinal materials, chemical raw materials and so on. The temperature of quick-freezing cold storage is generally -20℃ ~ -40℃.
Quick-frozen cold storage has the following storage effects: inhibiting respiration, reducing the consumption of organic substances, maintaining the excellent flavor and aroma of fruits and vegetables; Inhibit water evaporation and maintain the freshness of fruits and vegetables; Inhibit the breeding of pathogenic bacteria, control the occurrence of some physiological diseases, reduce the rate of fruit decay; Inhibit the activity of some late ripening enzymes, inhibit the production of ethylene, delay the process of late ripening and aging, maintain the fruit hardness for a long time, and have a long shelf life.
Frozen food cold storage temperature inside is commonly – 5 ℃ ~ 18 ℃, irregular put food in the freezer needs proposed, through the proposed refrigeration equipment, refrigeration cooling temperature of the rolls – 18 ℃, frozen library take goods shipment is not regular, and timing of cooling time for the specific requirements, mainly to prevent the deterioration of food, which is typical of the freezing cold storage.
Quick-frozen food cold storage is mainly used for the freezing and refrigeration of food, meat, poultry, aquatic products, meat food processing plants, dairy products factories, ice cream factories, pharmaceutical factories, blood bank centers, epidemic prevention stations, medicines, medicinal materials, medical supplies, chemical raw materials and other items. The lower the temperature, the better. The customer should determine the temperature according to the specific requirements of food. The lower the temperature, the higher the initial investment and operation cost of refrigeration equipment. It is recommended that when you choose and install the cold storage, according to the temperature of your refrigerated goods, we will provide you with scientific and reasonable design and optimization of supporting schemes.
