[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1-4As shown, a sterilization device for fruits and vegetables includes a pulse electric field generator 1 and a processing box 2. The processing box 2 has an opening on the side away from the pulse electric field generator 1. Slide rails 3 are provided at both the bottom and top of the processing box 2. Carriages 4 are provided on both the bottom and top slide rails 3. Two rotating shafts 5 are symmetrically arranged between the two carriages 4. A tray 6 is spaced apart on each rotating shaft 5. A driven gear 7 is provided at the lower end of each rotating shaft 5. A motor 8 is provided on the lower carriage 4. A main gear 9 is provided at the output end of the motor 8. The device also includes a toothed belt 10 for connecting the two driven gears 7 and the main gear 9. A... A sealing plate 11 is provided, and two parallel reinforcing plates 12 are provided on the sealing plate 11. A handle 13 is symmetrically provided between the two reinforcing plates 12. A collar 14 is rotatably connected to the handle 13. A control rod 15 is provided at one end of the collar 14, and a hook rod 16 is provided at the other end of the collar 14. Fixing blocks 17 that engage with the hook rod 16 are symmetrically provided on the outer surface of the processing box 2. A sleeve 18 is symmetrically provided on the outer surface of the sealing plate 11. An elastic element 19 is provided inside the sleeve 18. One end of the elastic element 19 is fixedly connected to the bottom of the sleeve 18, and the other end of the elastic element 19 is fixedly connected to the hook rod 16. The elastic element 19 is always in a tensioned state.

[0018] The pulse electric field generator 1 includes a DC energy storage module, a pulse forming module, an output matching module, and a control and monitoring module. When sterilizing fresh-cut fruits and vegetables, its electric field strength is 1-5MV / m, the pulse width is usually in the range of 1µs-1ms, and the pulse repetition frequency is 20-40KHz.

[0019] When sterilizing the packaged fresh-cut fruits and vegetables, first remove the tray 6 from the processing box 2. Specifically, hold the lower part of the handle 13 with both hands, and then use both thumbs to flip the control lever 15 inward, which shortens the distance between the two control levers 15. When the control lever 15 rotates, it drives the hook rods 16 on both sides to rotate through the collar 14, causing the hook rods 16 to separate from the fixing block 17. At this time, the sealing plate 11 can be moved, and the slide 4 can be moved along the slide rail 3, removing the rotating shaft 5 on the slide 4 and the tray 6 from the processing box 2. The staff can then place the packaged fresh-cut fruits and vegetables on the tray 6. Since there is operating space on both sides of the tray 6, at least two people can place the fresh-cut fruits and vegetables at the same time.

[0020] After the fresh-cut fruits and vegetables are stacked, push the sealing plate 11 and the slide 4 along the slide rail 3 by using the handle 13. At the same time, use both thumbs to continue rotating the control lever 15 towards each other, so that the hook 16 can pass through the fixing block 17 and engage with the fixing block 17. After the hook 16 engages with the fixing block 17, the sealing plate 11 closes the side opening of the processing box 2. Then, the fresh-cut fruits and vegetables on the tray 6 are sterilized by the pulse electric field generator 1. During the process, the control motor 8 is started. The output end of the motor 8 drives the main gear 9 to rotate, and through the engagement of the toothed belt 10 and the driven gear 7, it drives the two rotating shafts 5 to rotate, thereby driving the tray 6 and the fresh-cut fruits and vegetables on the tray 6 to rotate, thereby improving the sterilization efficiency and sterilization effect.

[0021] Furthermore, rollers 20 are symmetrically arranged at the lower end of the outer surface of the sealing plate 11. The rollers 20 can support the sealing plate 11 and facilitate its movement.

[0022] Furthermore, when the length of the elastic element 19 is in its shortest state, the end of the hook rod 16 can move along the outer surface of the fixing block 17 and engage with the fixing block 17. When the opening on one side of the processing box 2 is closed by the sealing plate 11, the hook rod 16 can be quickly engaged with the fixing block 17 without turning the control lever 15 with the thumb, thus improving the convenience of the hook rod 16 and the fixing block 17.

[0023] Furthermore, the upper surface of the tray 6 is provided with an annular groove 21, which facilitates the improvement of the stability of fresh-cut fruits and vegetables placed on the tray 6.

[0024] Furthermore, the outer surface of the sealing plate 11 is provided with an observation window 22, which facilitates observation of the situation inside the processing box 2.

[0025] When in use, the device can move the tray 6 outside the processing box 2 to reduce the obstruction of the processing box 2 on the tray 6, thereby making it easier to place packaged fresh-cut fruits and vegetables on the tray 6 and to remove the processed fresh-cut fruits and vegetables from the tray 6, improving the efficiency of fruit and vegetable placement and transfer, saving time, and improving sterilization efficiency.
