Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a separate quick-freezing device. Background technique [0002] The quick freezing of vegetables, fruits, seafood, meat and other ingredients is a frozen food made by processing fresh ingredients and then quickly freezing them. Its advantages are that it can be stored for a long time, and it can maintain the original color, taste and various nutrients of the ingredients to a large extent, and can effectively adjust the supply in low and peak seasons. [0003] In the related art, cold storage can be used for quick freezing of ingredients, but the cold storage adopts the method of cold air circulation, which has a long freezing time and poor fresh-keeping effect; or liquid nitrogen can be used for quick cooling, but the cost is extremely high, which is not conducive to large-scale operation. SUMMARY OF THE INVENTION [0004] The present invention aims to solve at least one...
