when the pressure detected by the pressure sensor is greater than the preset pressure, the controller opens the first electromagnetic valve 13 according to the pressure signal, and the vacuum pump 12 is started; when the pressure detected by the pressure sensor falls to a preset pressure, the controller closes the door of the first electromagnetic valve 13 according to the pressure signal, and opens the door of the second electromagnetic valve 14 after a preset time.
From the above, the vacuum system and the refrigerating system in the fresh cut flower precooling device provided by the application are used for realizing vacuum precooling, and compared with air cooling precooling, the cooling rate can be greatly accelerated. Meanwhile, the mixing tank in the aerosol system is matched with the antibacterial liquid discharged from the antibacterial liquid storage tank and fresh-keeping gas discharged from the fresh-keeping gas storage tank, the antibacterial liquid and fresh-keeping gas are mixed under the action of the gas-liquid mixing pump to form aerosol, and the aerosol is guided into the vacuum box through the aerosol outlet of the mixing tank. After entering the vacuum box, the aerosol can supplement water, prevent water loss in the precooling process of fresh flowers, keep fresh and inhibit bacteria, reduce decay, and realize the combination of precooling and fresh and inhibit bacteria by matching the aerosol system with the vacuum system and the refrigerating system. In conclusion, the precooling device has high precooling speed on the fresh cut flowers, and can supplement water, keep fresh and inhibit bacteria at the same time, thereby being beneficial to prolonging the storage period of the fresh cut flowers.
The embodiments of the present application have been described above, the foregoing description is exemplary, not exhaustive, and not limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or the improvement of technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
