With the end of the recent fishing ban, all kinds of delicious seafood have entered people's tables. We all know that fresh seafood products or aquatic products are the first thing. How to ensure the freshness of products? Many people will choose to install refrigerators to solve this problem. Many users do not know the difference of cold room for seafood and seafood quick freezer room.
Cold room for seafood: the temperature of the low-temperature freezer is generally from -22 to -25 degrees. It uses a variety of refrigeration equipment, that is, artificial refrigeration, to keep a certain low temperature in the room. The characteristics of the cold storage are as follows: the food is put into the cold storage step by step irregularly. After a while, the temperature of the cold storage reaches -25 ℃. There is no special cold storage design process and technical requirements for this period. There are strict requirements for the temperature of the cold storage. It is a typical cold storage between - 22℃and -25 ℃. Compared with the fresh-keeping storehouse, the function mechanism of the frozen storehouse is very different. Too low temperatures will cause the cell death of the food, such as meat seafood, and the freshness will be greatly affected. Therefore, the lower the temperature, the better the storage of fruits and vegetables.
Seafood quick freezer room: as the name suggests, the seafood freezer is a freezer for quick freezing seafood products, which is usually used with seafood freezer. Frozen seafood products can maximize the quality and flavor of seafood products, and provide a guarantee for maximizing reversible physical changes after thawing. Generally, the storage temperature of the seafood quick-frozen cold store is set as from -25 to -30 degrees, of course, the quick-frozen temperature of tuna is also extremely low, which is usually below -60 ℃. At the same time, the significance of quick freezing lies in quick freezing. Enterprises can inform the cold storage engineering companies, such as the cold storage house refrigeration, about the expected time of quick freezing completion, and let the engineering companies equip with appropriate refrigeration equipment, for example, the general quick freezing time is often set to 5-8 hours. In a word, when designing the construction scheme of the quick-frozen cold storage, the configuration, and location of the cold storage room refrigeration will be determined according to the requirements of the quantity, temperature and center temperature of the goods. When the central temperature of seafood products reaches -18 ℃, the quick freezing is completed, and then they can be transferred to the seafood freezer for long-term storage and preservation.
