Installation of vacuum pre cooling and preservation equipment for fruits and vegetables in wholesale markets

　　The vacuum pre cooling preservation equipment for fruits and vegetables is a device used for preserving vegetables and fruits. It can reduce the temperature of fruits and vegetables through vacuum cooling and cooling water circulation, thereby extending the shelf life of fruits and vegetables. This device has been widely used in vegetable and fruit wholesale markets, which can effectively improve the preservation effect of fruits and vegetables, reduce the loss of fruits and vegetables, and increase the sales price of fruits and vegetables. The working principle of the vacuum pre cooling and preservation equipment for fruits and vegetables is to place them in a vacuum chamber and reduce the air pressure around them by vacuuming, thereby accelerating the cooling process of the fruits and vegetables. At the same time, the device can also reduce the temperature of fruits and vegetables by circulating cooling water, thereby achieving the effect of preservation.
