Traditional explosion-proof freezers maintain goods in a low-temperature environment during freezing, as the items are unsuitable for bacterial growth, preserving them from spoilage. The nutrient fluid within the cell wall, which is water, forms ice needles within the cell wall. Over an extended freezing period, these ice needles pierce through the cell wall, allowing the water to escape. Consequently, after a period of freezing in traditional explosion-proof freezers, a significant amount of frost accumulates on the surface of the items, and a thick layer of frost forms inside the freezer's lining, necessitating regular cleaning.
The low-temperature explosion-proof refrigerator freezing process involves the rapid movement of nutrients, specifically water, across the ice crystal band within each tissue cell system. This water reacts quickly within the cell walls to form tiny ice crystals, which are not as socially sharp as larger ones. The ice crystals are stored within the cell walls, thereby preserving cell vitality. Consequently, as long as the temperature range for storage remains within the specified low-temperature limits, prolonged freezing ensures that the freshness of the items is well-maintained.
