Abstract

The invention relates to a pre-unfreezing, rapid unfreezing, sterilization and fresh-keeping device of foods, and belongs to the technical field of food processing. According to the device disclosed by the invention, hot air is used to unfreeze foods; the heated air is conveyed to the surface of the frozen foods by a fan to exchange heat with the frozen foods; unfreezing with hot air can enable the foods to be uniformly heated; besides, a step-by-step unfreezing method is adopted, so that the temperature of the hot air is gradually increased, the temperature of the foods slowly rises in the unfreezing process without destroying the nutrients and the texture of the foods, and besides, water mist is added to the hot air in the unfreezing process, wherein the water mist can effectively lowerthe temperature of the food surface, so that the food surface is prevented from being coked in the unfreezing process, and the quality of freezing the food is effectively improved.

Description

Technical field [0001] The invention relates to a food pre-thawing and quick thawing sterilization fresh-keeping device, belonging to the technical field of food processing. Background technique [0002] With the development of the food industry and the improvement of people's living standards, people's requirements for food are becoming more and more stringent, not only requiring a variety of types, but also paying more attention to the nutritional value and quality of food. Thawing is to restore the thawing of frozen materials to the fresh state before freezing. The thawing process of meat is actually the process in which the ice crystals formed in the frozen meat melt into water. There are many ways to defrost meat. The size and distribution of ice crystals and the loss of juice during the thawing process will have a direct impact on meat quality, such as color deterioration, flavor decline, dehydration, fat oxidation, protein degradation, and denaturation. In terms of qualit...
