[0002] A precooler is a device used to quickly lower the temperature of items. It is widely used in food processing, agriculture, medicine, chemical industry and other industries. Its main purpose is to reduce the temperature of materials (such as fruits and vegetables, cooked food, seafood, etc.) from the higher temperature after harvesting or processing to an ideal low temperature state in a short period of time, so as to slow down metabolism, inhibit bacterial growth, maintain freshness and extend shelf life.

[0003] Based on the above, the inventors have found the following problems: current pre-cooling machines usually use vacuum pre-cooling or refrigerant pre-cooling. The cost of vacuum pre-cooling machines is relatively high, while refrigerant pre-cooling machines use a refrigeration system to circulate the refrigerant in a heat exchanger to take away heat for pre-cooling. However, refrigerant pre-cooling easily produces condensed water on the surface of the material, resulting in increased humidity in the material, affecting the quality and making it inconvenient to use.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a compressed air low-temperature precooling unit is provided to achieve a more practical purpose. Utility Model Content
