Description

Technical Field

[0001] This utility model relates to the field of zucchini seed processing technology, and specifically discloses a zucchini seed disinfection and dehydration machine. Background Technology

[0002] Disinfection and dehydration of zucchini seeds are crucial steps affecting their germination rate and planting quality. Currently, most technical solutions in this field focus on combining mechanical dehydration with chemical disinfection, but problems such as insufficient efficiency, residual contamination, and seed damage still exist.

[0003] For example, Chinese utility model patent CN220733452U discloses a zucchini seed disinfection and dehydration machine, which improves seed dispersion by setting a rotating lower shell, a stirring rod, and a dispersion mechanism, and uses methyl isofenphos solution for chemical disinfection. However, this solution has the following limitations: First, relying on chemical soaking for disinfection can easily cause chemical residues, threatening the ecological environment and food safety; second, the mechanical dispersion structure (such as the stirring plate and dispersion plate) operates synchronously with the shell rotation, which may cause mechanical damage to the seeds due to repeated collisions, affecting the germination rate; third, hot air dehydration relies on a single fan, which has high energy consumption and insufficient temperature and humidity control precision, easily leading to uneven heating of the seeds.

[0004] Based on this, those skilled in the art are dedicated to developing an innovative solution to address the risks of chemical pollution, potential mechanical damage, and low energy efficiency in existing technologies, thereby meeting the demands of modern agriculture for green and intelligent seed processing equipment.

The two ends of the mesh cylinder are rotatably connected to the outer cylinder via bearings. An ozone atomizing nozzle, an ultraviolet germicidal lamp plate, and an air distribution pipe are arranged sequentially from front to back above the inner axis of the mesh cylinder. A spiral conveying mechanism is arranged on the side of the outer cylinder. The spiral conveying mechanism includes a conveying cylinder with a feeding port, an auger arranged inside the conveying cylinder, and a rotary motor for driving the auger on the conveying cylinder. The end of the conveying cylinder is fixedly connected to the outer cylinder and communicates with the mesh cylinder. A slag discharge pipe and a material discharge pipe are respectively inclined downward on both sides of the bottom of the outer cylinder, and the material discharge pipe communicates with the mesh cylinder.

[0007] It also includes a drive mechanism for rotating the mesh cylinder.

[0010] As a preferred embodiment of the zucchini seed disinfection and dehydration machine of this utility model, the ultraviolet sterilization lamp plate includes a base plate fixedly connected to the inner wall of the outer cylinder and a plurality of ultraviolet lamp beads equidistantly embedded at the bottom of the base plate; the outer cylinder integrates a controller, a hot air blower and an ozone generation system.

[0011] The air inlet of the hot air blower is equipped with a filter cover, and the air inlet is connected to the air distribution pipe through the air supply pipe.

[0012] The ozone generation system includes an ozone generator and a gas-liquid mixing pump. The input end of the gas-liquid mixing pump is connected to the ozone generator, and the output end is connected to the ozone atomizing nozzle tube via a constant pressure pipeline.

Furthermore, the pneumatic valves and controllers work together to automate slag and material discharge, avoiding the risk of cross-contamination caused by manual operation. The overall airtightness of the equipment is enhanced, further ensuring the hygiene and consistency of the processing. Attached Figure Description

[0029] It also includes a drive mechanism for rotating the mesh cylinder 2.

[0030] In this embodiment: Zucchini seeds are conveyed into the mesh cylinder 2 via a spiral conveyor mechanism 7. The drive mechanism rotates the mesh cylinder 2, causing the seeds to tumble inside. The ultraviolet germicidal lamp plate 5 emits ultraviolet light to initially sterilize the seeds, and the ozone atomizing nozzle pipe 4 sprays ozone atomized liquid to further disinfect the seeds. After disinfection, the hot air generated by the hot air blower 21 is evenly distributed into the mesh cylinder 2 through the air distribution pipe 6 to dehydrate and dry the seeds. During the seed movement, impurities and moisture are discharged through the mesh holes of the mesh cylinder 2 and discharged from the equipment through the slag discharge pipe 12. The disinfected and dehydrated seeds are discharged through the material discharge pipe 13.

[0031] As a technical optimization of this utility model, the driving mechanism includes a toothed sleeve 14 fixed to the outer wall of the mesh cylinder 2, a drive wheel 15 meshing with the toothed sleeve 14, and a drive motor 16 driving the drive wheel 15.

The height of the spiral guide plate 17 is 1 / 5 to 1 / 3 of the radius of the mesh cylinder 2, and the ratio of the spiral pitch of the spiral guide plate 17 to the length of the mesh cylinder 2 is 1:3.

[0034] In this embodiment, a spiral guide plate 17 of a specific size is provided on the inner wall of the mesh cylinder 2 to extend the residence time of the seeds in the mesh cylinder 2, guide the seeds to move evenly, and prevent local accumulation; the ratio of the spiral pitch to the length optimizes the flow efficiency, taking into account both the processing effect and the production capacity.

[0035] As a technical optimization of this utility model, the ultraviolet germicidal lamp plate 5 includes a base plate 18 fixedly connected to the inner wall of the outer cylinder 1 and a plurality of ultraviolet lamp beads 19 equidistantly embedded at the bottom of the base plate 18; the outer cylinder 1 integrates a controller 20, a hot air blower 21 and an ozone generating system.

[0038] In this embodiment: ultraviolet light provides full-coverage sterilization, ozone atomization penetrates the crevices on the seed surface, and hot air rapidly dehydrates to create a secondary disinfection environment, achieving triple synergistic sterilization (physical + chemical + thermal) and reducing the risk of pathogen residue.

[0039] As a technical optimization of this utility model, a temperature and humidity sensor 25 is provided on the inner wall of the outer cylinder 1. The temperature and humidity sensor 25 is connected to the controller 20 by signal.

[0040] In this embodiment: the temperature and humidity sensor 25 monitors in real time, and the controller 20 dynamically adjusts the hot air parameters to avoid damage to seed activity caused by high temperature and humidity, accurately control the dehydration rate, and ensure the seed germination rate.

[0041] As a technical optimization of this utility model, the blades of the auger 10 are made of food-grade silicone material, and the gap between the edge of the blade and the inner wall of the outer cylinder 1 is 1-3mm.

[0042] In this embodiment: food-grade silicone blades achieve flexible conveying, reduce mechanical compression damage to seeds, control the gap to prevent seeds from getting stuck, and avoid impurities generated by friction between the blades and the inner wall of the mesh cylinder 2.

[0043] As a technical optimization of this utility model, both the slag discharge pipe 12 and the material discharge pipe 13 are equipped with pneumatic valves 26, which are electrically connected to the controller 20 and controlled by its program.

[0045] Working principle and usage process of this utility model:

The drive mechanism rotates the mesh cylinder 2, and the ultraviolet germicidal lamp plate 5 and the ozone atomizing nozzle pipe 4 work simultaneously to disinfect the seeds. After disinfection, the hot air generated by the hot air blower 21 dehydrates the seeds through the air distribution pipe 6. During this process, the temperature and humidity sensor 25 monitors the temperature and humidity inside the outer cylinder 1 in real time, and the controller 20 adjusts the operation of the hot air blower 21 according to the data. Impurities and moisture in the seeds are discharged through the mesh of the mesh cylinder 2 and discharged from the equipment through the slag discharge pipe 12. The pneumatic valve 26 of the slag discharge pipe 12 is controlled to open and close according to the program of the controller 20. After disinfection and dehydration are completed, the pneumatic valve 26 of the discharge pipe 13 is opened, and the disinfected and dehydrated seeds are discharged from the equipment through the discharge pipe 13.
