Description

technical field [0001] The invention relates to the technical field of food freezing, in particular to a double-helix freezer with a cold air circulation diversion function. Background technique [0002] With the continuous growth of the domestic economy and the gradual improvement of the freight industry, in order to improve the quality of life, more and more frozen foods appear on the market. Through frozen transportation, freight costs can be reduced and transportation losses can be reduced, so they are widely favored by the market. . [0003] The existing quick-freezing devices on the market often cannot guarantee the frozen quality of food, resulting in uneven quality of frozen products, especially during cold chain transportation, because the transportation and storage conditions cannot be strictly guaranteed, so the quality of quick-frozen food is often the decisive factor. In order to ensure the freezing effect, the conventional refrigeration device uses a variety o...

[0003] The existing quick-freezing devices on the market often cannot guarantee the frozen quality of food, resulting in uneven quality of frozen products, especially during cold chain transportation, because the transportation and storage conditions cannot be strictly guaranteed, so the quality of quick-frozen food is often the decisive factor

In order to ensure the freezing effect, the conventional refrigeration device uses a variety of devices to distribute the cold air in the freezing chamber as evenly as possible, so as to ensure uniform freezing as much as possible. However, most of the existing refrigeration devices use cold air ejection cooling The method is to cool through the freezing air flow, and the lack of constraints on the freezing air flow makes the freezing effect unsatisfactory. Some incompletely frozen products are packaged together with qualified products, and unqualified frozen products are likely to cause bacterial growth. It is not conducive to long-term preservation and affects the overall quality of the product

Most of the existing foods are exposed to the freezing chamber when they are quick-frozen. Therefore, it is necessary to prevent the outside air from entering. This also makes it impossible for conventional detection methods to detect the internal food freezing quality in real time. It can only be detected after the freezing is completed. , thus greatly restricting the quick-freezing efficiency
