Description

Technical Field

[0001] The utility model relates to the technical field of quick-freezing equipment, in particular to a food quick-freezing machine with an anti-adhesion mechanism. Background Art

[0002] A refrigerator is a mechanical device that uses a compressor to change the pressure change of the refrigerant gas to achieve low-temperature refrigeration. The working principle is: the liquid refrigerant in the evaporator absorbs heat from the water and begins to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water, and the liquid refrigerant also completely evaporates and becomes a gas. It is then sucked in and compressed by the compressor (pressure and temperature increase), becoming a high-temperature and high-pressure refrigerant that releases heat through the condenser (air cooling / water cooling), condensing into a low-temperature and high-pressure liquid refrigerant, and after being throttled by the throttle valve, it becomes a low-temperature and low-pressure refrigerant and enters the evaporator. Refrigeration is completed through multiple cycles.

[0003] Freezers are widely used in the field of food processing to keep food fresh through quick freezing. However, due to the presence of moisture on the surface of the food, it will condense and stick to the surface of the conveyor belt during the quick freezing process and is not easily separated by the conveyor belt, affecting the processing efficiency.
