When people buy the food in the chest freezer in the supermarket, they often look at whether the freezing power in the chest freezer is enough in order to judge whether the food in the chest freezer is fresh enough. On the basis of paying attention to freezing, they actually pay more attention to preservation. How is the freezing and preservation function of the Chest Freezer Factory applied?
1. Keep fresh and keep healthy.
Nowadays, the supermarket chest freezer can not only keep fresh, but also keep healthy, that is, the quality of food will not change too much, and the food can be original, that is, the taste of food stored in the supermarket chest freezer will not change too much.
2. Freezing should be strong and fast.
To avoid food taste and nutrition loss and more damage, quick freezing must be strong and fast, because the cell fluid of frozen food will form ice crystals at 0 and -5 degrees, which will form the maximum ice crystal formation zone. If frozen food stays in the maximum ice crystal formation zone for too long, the ice crystals will puncture the cell wall too much, resulting in excessive loss of food nutrition.
Therefore, in order to ensure that the meat passes through the ice crystal forming zone at the fastest speed in the shortest time, the quick freezing time of the fresh-keeping supermarket chest freezer should be controlled in the shortest time. According to the fresh-keeping supermarket chest freezer introduced in the market, most manufacturers control this time within 30 minutes.
We remind consumers not to go into misunderstanding when choosing a chest freezer, because excessive freezing power will not only increase users' expenses, waste resources, but also destroy the internal organization of food, thus affecting nutrition, but can not keep fresh.
