Fresh cold storage, many friends think of a cold storage for preserving fruits and vegetables at first glance. Is only a cold storage that preserves fruits and vegetables the 'fresh cold storage'? There are two types of refrigerators: "refrigerated preservation" and "frozen preservation". In fact, from a professional perspective, any refrigeration engineering equipment that has an extended storage period for food and a preservation effect on food quality can be called a preservation cold storage.
What is the difference between a frozen and refrigerated cold storage?
1) There are significant differences between refrigerated and refrigerated warehouses, but both have a common feature of using low temperatures to preserve food in cold storage.
2) Freeze preservation is the process of freezing the tissue of food and then keeping it at a low temperature for storage.
What are the main items suitable for storage in a refrigerated warehouse?
1) Usually suitable for some meats, seafood, ice cream, etc. Once frozen, most of the life activities of frozen fresh food in the freezer will stop, making it suitable for long-term preservation of various low-temperature fresh foods.
2) The temperature for the installation of refrigerated low-temperature warehouses is generally between -22 and -25. It uses various refrigeration equipment, namely artificial refrigeration, to maintain a certain low temperature indoors. Many foods, such as ice cream and seafood, need to be stored at a temperature of -25 ℃ to prevent spoilage. For example, if ice cream is not stored at -25 ℃, its fragrance will disappear; The freshness and taste of seafood are much worse.
Which is' better 'between a refrigerated storage room and a refrigerated storage room?
1) If storing the same type of food, a frozen storage room has a longer preservation time compared to a regular cold storage room, but a frozen storage room can cause a certain degree of damage to the organizational structure of the food. Therefore, it is not suitable for the preservation of fruits and vegetables, but can be used for the preservation and storage of low-temperature meat and seafood.
2) The installation temperature of refrigerated storage is generally -15 ℃ to -18 ℃. Generally, food is gradually placed in the cold storage on an irregular basis. After a period of time, the temperature of the cold storage reaches -18 ℃, and pickup is also irregular and irregular. There are no specific requirements for this' period of time ', which is a typical refrigerated warehouse. For example, meat and aquatic products have high storage temperature requirements to ensure that the internal products do not deteriorate. And during the sales process, they are also taken out and stored irregularly. Generally, the cold storage in large supermarkets is refrigerated.
What about the refrigerated storage? What goods are suitable for storage?
1) Cold storage can reduce the life activities of fruits, vegetables, seeds, fruits, and other foods through a certain low temperature, extending their freshness and shelf life. At this temperature, the life activities of food are not completely terminated, but are very weak. Whether to choose a refrigerated storage for food storage depends on the storage characteristics of the food, such as fruits and vegetables, crops, low-temperature packaged foods, etc. It is more suitable to choose a refrigerated storage.
