The difference between fresh-keeping cold storage and refrigerated cold storage.
Fresh-keeping cold storage is a kind of high-configuration refrigeration equipment, using advanced refrigeration technology and insulation materials, which can control the temperature within a certain range, while maintaining the suitability of humidity and gas composition, so as to keep food, fruits, vegetables and other items fresh. Fresh cold storage usually uses a high temperature and high humidity environment to maintain the freshness of the items, but not all items are suitable for storage in this environment.
Refrigerated cold storage is a more common type of refrigeration equipment, which mainly uses a combination of refrigerant and compressor to reduce the temperature to refrigerate items. The temperature range of refrigerated cold storage is usually below -18, which is suitable for low-temperature refrigeration of some items that need to be stored for a long time.
In addition to the difference in temperature control, there are also certain differences in the structure and design of fresh-keeping cold storage and refrigerated cold storage. Fresh cold storage usually uses a high temperature and high humidity environment, so it is necessary to control humidity and gas composition, while also taking into account factors such as ventilation. Refrigerated cold storage, on the other hand, pays more attention to the refrigeration effect and temperature stability, so there are different requirements for the selection of insulation materials and refrigerants.
Although fresh-keeping cold storage and refrigerated cold storage are both refrigeration equipment, there are certain differences in temperature control, structure and design, which need to be selected and used according to different needs.
How much is the right refrigeration temperature in the cold storage.
The choice of cold storage refrigeration temperature needs to be determined according to different items and storage time. Generally speaking, for some items that need to be stored for a long time, such as meat, poultry, etc., the refrigeration temperature should be controlled below -18, which can effectively inhibit the growth and reproduction of bacteria, while maintaining the nutrition and taste of food.
For some foods that need to be stored for a short time, such as vegetables and fruits, the refrigeration temperature can be slightly higher, but it should not exceed 0. This avoids frostbite and preserves the freshness and nutritional value of the food.
When choosing the refrigeration temperature of cold storage, it needs to be determined according to different items and storage time. At the same time, it is also necessary to pay attention to controlling factors such as humidity and gas composition to ensure the safety and nutritional value of food.
