Description

Technical Field

[0002] The vacuum pre-cooler is a cooling processing equipment that places vegetables, flowers, meat, cooked food, etc. in a vacuum chamber and uses a vacuum pump to extract the air and water vapor in the vacuum chamber to reduce the air pressure in the vacuum box.

[0003] Application scenarios and functions of precoolers: Precoolers are widely used in agricultural product preservation, food processing, chemical industry and other industries and scientific research fields. In particular, they have made great contributions to ensuring the safety and freshness of fruits and vegetables and food in daily life. Especially during the epidemic, the storage and preservation time of fruits and vegetables will be affected due to the resistance of transportation time and distribution space. Precoolers and cold storages are to ensure the freshness and safety of food. After precooling, the shelf life of fruits, vegetables and food is extended, the original color is preserved, and the taste of food is preserved.

[0004] When the vacuum precooler is in use, in order to ensure that the internal pressure is constant, a constant pressure device is needed to perform constant detection of the internal pressure. In the event of unstable pressure, the internal pressure can be detected and adjusted. The existing precooler needs to use a pressure detection mechanism and a pump body mechanism to detect and adjust the internal pressure.
