Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, and in particular to a small commercial refrigerator capable of prolonging the fresh-keeping time of food. Background Art

[0002] When food is stored in ordinary refrigerators for a long time, large ice crystals are likely to form on the surface of the food. However, large ice crystals can easily cause the surface of the food to crack, especially for fruits and vegetables, thereby accelerating the spoilage of fruits and vegetables and reducing the shelf life.

[0003] Studies have shown that magnetic fields can inhibit the formation of large ice crystals during the freezing process of food. Therefore, it is easier for small ice crystals to form inside the food, thereby better protecting the quality and taste of the food and promoting food preservation. This is mainly because the magnetic field has a magnetizing effect on water molecules. The viscosity and association of magnetized water molecules are reduced, and their activity is increased, making them less likely to freeze. The overall freezing point of the object is lowered, and the cluster structure becomes smaller, making it easier to produce small ice crystals. During the freezing process, small ice crystals are less likely to pierce the cell walls than large ice crystals, thereby maintaining the nutrients in the food cells and greatly improving the effect of freezing and preservation.

[0004] Moreover, there have been many studies on the use of magnetic fields to assist in the freezing of meat. Literature has shown that the freezing time of pork, beef, and seafood is significantly shortened and the quality is improved under -18°C freezing conditions assisted by a 0.05-15mT magnetic field. The freezing time of beef can be shortened by 36.7%, and the loss rate of thawing juice is reduced. Utility Model Content
