Description

Technical Field

[0001] This utility model relates to the field of zucchini seed processing technology, and specifically discloses a sterilization device for zucchini seed processing. Background Technology

[0002] Zucchini, as an important vegetable crop, is susceptible to seed contamination by pathogens, molds, and other microorganisms during processing, severely impacting germination rate and storage stability. Traditional seed sterilization methods suffer from the following technical drawbacks:

[0003] Existing sterilization methods for zucchini seed processing typically employ chemical soaking: soaking with chemical agents such as sodium hypochlorite. Although this method has a good sterilization effect, it carries the risk of chemical residues, which may affect seed viability and food safety, and also generates harmful wastewater. Alternatively, a single ultraviolet lamp can be used for irradiation, but there are blind spots when the seeds are stacked, resulting in insufficient sterilization.

[0004] Furthermore, whether chemical soaking or ultraviolet irradiation is used, frequent manual loading and unloading are usually required, which is inefficient and may expose operators to harmful gases such as ozone, posing safety hazards. Therefore, a sterilization device for zucchini seed processing is needed to solve this problem. Utility Model Content

Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-4 A sterilization device for zucchini seed processing includes a sterilization shell 8 and a collection box 1. The sterilization device is installed inside the sterilization shell 8, and an automatic loading and unloading mechanism is installed on the outside of the sterilization shell 8.

[0027] The sterilization device includes multiple ultraviolet lamps 23 installed at the top of the inside of the sterilization shell 8. A mesh tray 13 is fixedly connected through the lower end face of the sterilization shell 8. A flow guide shell 14 is fixedly connected to the lower end of the sterilization shell 8. Multiple evenly distributed through holes 15 are opened through the upper end of the flow guide shell 14. Two symmetrically distributed ozone generators 16 are fixedly installed through the lower end of the flow guide shell 14. A vertical rod 11 is rotatably connected to the top of the inside of the sterilization shell 8. A material leveling rack 12 is fixedly connected to the lower end of the vertical rod 11.

[0028] The automatic loading and unloading mechanism includes a bracket 17 fixedly connected to the rear end of the collection box 1. A rotating shaft 21 is rotatably connected through the outer wall of the bracket 17. The front end of the rotating shaft 21 is fixedly connected to the sterilization shell 8. The outer wall of the sterilization shell 8 is connected to the discharge pipe 10 with a butterfly valve and the feed hopper 7. An electric push rod 3 is installed at the right end of the collection box 1. An installation frame 4 is fixedly connected to the output end of the electric push rod 3. A storage box 5 is fixedly connected through the upper end of the installation frame 4. A guide pipe 6 with a butterfly valve is connected to the lower end of the storage box 5.

[0029] A drive mechanism is provided at the rear end of bracket 17.

[0030] In this embodiment: During feeding, the electric push rod 3 pushes the mounting frame 4 to move along the slide groove of the horizontal plate 2, aligning the storage box 5 with the feed hopper 7. The butterfly valve of the guide pipe 6 opens, and the seeds enter the sterilization shell 8 through the feed hopper 7. The second motor 9 drives the vertical rod 11 to rotate the evenly spreading rack 12, spreading the seeds evenly on the mesh tray 13. The ultraviolet irradiation lamp 23 is activated to sterilize the seed surface from all directions. The ozone generator 16 generates ozone gas, which evenly penetrates into the seed layer through the through holes 15 of the guide shell 14. The uniform feed rack 12 rotates continuously to ensure that the seeds are constantly turned over, achieving sterilization without dead corners. After sterilization, the electric push rod 3 is reset, causing the guide pipe 6 to move away from the feed hopper 7. The sterilization shell 8 tilts under the action of the drive mechanism, causing the discharge pipe 10 to face downwards. The butterfly valve on the outer wall of the discharge pipe 10 is opened to allow the seeds to fall into the collection box 1. The butterfly valve on the outer wall of the discharge pipe 10 is closed, and the sterilization shell 8 is reset. The above steps are repeated to carry out the second batch of seed sterilization. This process can be controlled by the controller to operate each component, eliminating the need for frequent manual loading and unloading.

[0031] As a technical optimization of this utility model, the drive mechanism includes a worm gear 20 fixedly connected to the outer wall of the rotating shaft 21, two left and right fixed plates 18 fixedly connected to the rear end of the bracket 17, a worm 19 rotatably connected between the two fixed plates 18 and meshing with the worm gear 20, and a first motor 22 with its output end fixedly connected to the worm 19 installed on the outer wall of the right fixed plate 18.

[0032] In this embodiment: the first motor 22 rotates through the worm gear 19, and the worm gear 19 drives the worm wheel 20 and the rotating shaft 21 to rotate, so that the sterilization shell 8 rotates as a whole.

[0033] As a technical optimization of this utility model, a second motor 9 with an output end fixedly connected to the vertical rod 11 is installed at the upper end of the sterilization shell 8.

[0034] In this embodiment, the vertical rod 11 can be driven to rotate by the second motor 9.

[0035] As a technical optimization of this utility model, a horizontal plate 2 is fixedly connected to the right end of the collection box 1. A sliding groove is provided at the upper end of the horizontal plate 2, and the lower end of the mounting bracket 4 is slidably connected to the horizontal plate 2 through the sliding groove.

[0036] In this embodiment, the stability of the movement of the mounting bracket 4 can be increased by sliding the mounting bracket 4 with the horizontal plate 2.

[0037] As a technical optimization of this utility model, an observation window is installed through the outer wall of the sterilization shell 8.

[0038] In this embodiment, the operator can visually monitor the distribution of seeds inside the sterilization shell 8, which facilitates timely adjustment of the feed rate.

[0039] As a technical optimization of this utility model, multiple ultraviolet irradiation lamps 23 are arranged in a circular array.

[0040] In this embodiment, ultraviolet light can simultaneously irradiate the seeds from multiple angles, eliminating the shadow areas present in traditional unilateral irradiation and ensuring that each seed receives uniform sterilization treatment.

[0041] As a technical optimization of this utility model, a controller is installed on the right end of the mounting bracket 4.

[0042] In this embodiment: the controller adopts a PLC control system and is electrically connected to the ultraviolet irradiation lamp 23, ozone generator 16, electric push rod 3, first motor 22, and second motor 9. It automatically adjusts the sterilization time, ozone concentration, and ultraviolet intensity through a preset program.

[0043] The working principle and usage process of this utility model are as follows: During feeding, the controller starts the electric push rod 3 to push the mounting frame 4 along the slide groove of the horizontal plate 2, so that the storage box 5 is aligned with the feed hopper 7. The butterfly valve of the guide pipe 6 is opened, and the seeds enter the sterilization shell 8 through the feed hopper 7. The second motor 9 drives the vertical rod 11 to rotate the uniform feed rack 12, spreading the seeds evenly on the mesh tray 13. The ultraviolet irradiation lamp 23 is activated to sterilize the seed surface by irradiation from all directions. The ozone generator 16 generates ozone gas, which evenly penetrates into the seed layer through the through holes 15 of the guide shell 14. The uniform feed rack 12 continues to rotate to ensure... The seeds are continuously turned over to achieve sterilization without dead angles. After sterilization, the electric push rod 3 is reset, moving the guide pipe 6 away from the feed hopper 7. The first motor 22 rotates through the worm gear 19, which drives the worm wheel 20 and the rotating shaft 21 to rotate, causing the sterilization shell 8 to rotate as a whole. The sterilization shell 8 tilts downward, causing the discharge pipe 10 to point downward. The butterfly valve on the outer wall of the discharge pipe 10 is opened, allowing the seeds to fall into the collection box 1. The butterfly valve on the outer wall of the discharge pipe 10 is closed, and the sterilization shell 8 is reset. The above steps are repeated to perform the second batch of seed sterilization. This process can be controlled by the controller to operate each component, eliminating the need for frequent manual loading and unloading.
