[0002] A quick freezer is a professional storage tool for storing various foods that need to be frozen. It is mainly used in business to quickly refrigerate food to keep the nutrients in the food and keep the taste fresh. Most of the food quick freezing in existing frozen food factories is completed by quick freezers, and the temperature of the quick freezer is generally -15℃~-35℃.

[0003] There are two main refrigeration modes for food quick freezers on the market. One is to use a compressor refrigeration unit for refrigeration; the other is to use liquid nitrogen refrigeration. The compressor refrigeration unit is characterized by large equipment size and low quick freezing cost, but slow refrigeration speed and high dry consumption; while the liquid nitrogen refrigeration quick freezer is characterized by compact equipment size, extremely fast refrigeration speed and low dry consumption, but the refrigeration cost is two or three times higher than that of compressor refrigeration. The refrigeration speed seriously affects the taste of quick-frozen food. Different foods have different refrigeration and quick freezing requirements. A single refrigeration method cannot meet the quick freezing needs of all foods. In addition, the size of the quick-freezing box is difficult to adjust according to actual usage, which is not practical and wastes a lot of cold air during the switch cabinet pickup process, which is not energy-saving.
