Description

Technical Field

[0001] The utility model belongs to the technical field of food processing, and in particular relates to food pre-cooling equipment. Background Art

[0002] Pre-cooling is a general term for the cooling of food before refrigerated transportation and high-temperature refrigeration, as well as the rapid cooling process before quick freezing. Common pre-cooling methods include air pre-cooling, vacuum pre-cooling, and water pre-cooling. Vacuum pre-cooling utilizes vacuum pre-cooling technology, using a vacuum pump to extract air and water vapor from a vacuum tank to reduce the pressure inside the vacuum chamber. The principle is that in a low-pressure environment, the boiling point of water decreases, the latent heat of evaporation increases, and the free water on the surface of the cooled object vaporizes, removing heat from the object and the surrounding environment, achieving a cooling effect. Essentially, it is a low-temperature boiling process for food.

[0003] Different foods have different moisture contents. During vacuum cooling, high-moisture foods evaporate and drip into the cooling chamber, making it difficult to clean. Low-moisture foods lose moisture, shrinking and deteriorating in taste. Existing cooling machines only have one cooling zone and lack internal moisture management, making them less practical.
