At this time, since the vegetable sterilization tank 3 is tilted at a certain angle and through the action of the multiple through holes 1 on the spiral plate 5, the vegetable sterilization liquid in the vegetable sterilization tank 3 is transported to the sterilization liquid storage box 9 through the delivery pipe 3 13, thereby achieving the effect of collecting and maintaining the vegetable sterilization liquid at a constant temperature; at the same time, in the process of transporting the vegetable sterilization liquid to the sterilization liquid storage box 9 through the delivery pipe 3 13 (as shown in the attached figure), Figure 4 (as shown by the arrow in the middle), the filter cartridge 20 can filter out impurities in the vegetable sterilization liquid; then, the motor 6 is started and the solenoid valve on the discharge pipe 15 is opened. At this time, the spiral plate 5 is rotated in the vegetable sterilization tank 3 by the drive of the motor 6 and the transmission of the gear 7, the gear ring 8 and the round tube 14, and the sterilized vegetables are transported to the discharge pipe 15 and discharged through the discharge pipe 15. In summary, the effect of facilitating the taking and placing of vegetables is achieved; then, the above operation is repeated;

[0038] The heating plate 18 can heat the vegetable sterilizing liquid in the sterilizing liquid storage box 9, so that it can be quickly heated by the heating plate 18 when needed, which can reduce the time for heating the vegetable sterilizing liquid that has cooled down, and is conducive to saving energy consumption.

[0039] The technical progress achieved by the present invention compared with the existing technology is that through the cooperation of various components, not only can the sterilization of vegetables be achieved, but also the vegetable sterilization liquid can be stored at a constant temperature, which is beneficial to saving energy consumption and improving efficiency.
