Description

Technical Field

[0001] The present invention belongs to the technical field of sterilization in agricultural product processing, and particularly relates to a sterilization device for agricultural product processing. Background Art

[0002] An agricultural product processing sterilization device is a type of equipment used for sterilizing agricultural products to be processed. Common agricultural product sterilization methods mainly include: pasteurization, microwave sterilization, ultraviolet sterilization, ultra-high pressure sterilization, solution sterilization. Among them, ultraviolet sterilization is widely used in the production and processing fields of agricultural products such as meat, dairy products, soy products, fruits and vegetables due to its advantages of energy conservation, environmental protection, no chemical drug residues, and no impact on the taste and nutrition of food.

[0003] In the prior art, common agricultural product processing sterilization devices mainly use the method of arranging ultraviolet sterilization devices outside the agricultural products to be processed to irradiate and sterilize the agricultural products. Such a method can only irradiate and sterilize the local part of the agricultural products, and cannot sterilize the agricultural products comprehensively and evenly.

[0004] Although some agricultural product processing sterilization devices achieve the purpose of irradiating and sterilizing agricultural products from multiple angles and in all directions by setting a vibration function and vibrating the agricultural products. For example, the Chinese invention patent with the patent number CN105054216B discloses a mung bean sterilization device. This application provides such a mung bean sterilization device, including a sterilization box, a groove, an ultraviolet lamp tube, a movable plate, a lifting frame, a swinging seat, a cylinder, a wedge-shaped block, a slide rail, a slider, a piston, a cylinder body, a lifting rod, a cylinder, a spring I, a spring plate, a steel ball, a spring II and a box cover. The sterilization box, the swinging seat, the slide rail and the cylinder body are respectively installed on the lifting frame. The wedge-shaped block and the piston are in sliding contact connection. The wedge-shaped block is connected through the slider and the slide rail, and the cylinder is connected with the wedge-shaped block. The present invention realizes the function of sterilizing mung beans in all directions, has a sterilization effect, and has a simple structure, is convenient for processing, manufacturing, maintenance and repair.

[0005] However, it can be seen from the content recorded in the specification and the accompanying drawings of the specification that although such agricultural product processing sterilization devices improve the effect of irradiating agricultural products from multiple angles by vibrating, the vibration amplitude of the agricultural products is easily affected by the amount of agricultural products to be processed. For example, when the amount of agricultural products to be processed added is large, the vibration amplitude of the agricultural products in the central position is small. When the vibration amplitude of the agricultural products to be processed is small, there is still a problem that the agricultural products to be processed cannot be sterilized comprehensively and evenly. This makes such agricultural product processing sterilization devices have problems of poor sterilization efficiency and poor sterilization comprehensiveness.

[0006] The information disclosed in this background section is only intended to enhance the overall understanding of the background of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art known to those of ordinary skill in the art. Summary of the Invention

[0007] An object of the present invention is to provide a sterilization device for agricultural product processing, which can improve the efficiency and comprehensiveness of sterilization treatment of agricultural products.

[0008] To achieve the above object, the technical solution provided by a specific embodiment of the present invention is as follows:

[0009] A sterilization device for agricultural product processing, comprising: a sterilization kettle body, an interpenetrating multi-directional sterilization mechanism, and a pulsed material turning mechanism.

[0010] The interpenetrating multi-directional sterilization mechanism is assembled in the sterilization kettle body. The interpenetrating multi-directional sterilization mechanism is used for lifting, vibrating, stirring, and mixing the sterilization treatment of agricultural products. The interpenetrating multi-directional sterilization mechanism includes an interpenetrating bottom plate, the interpenetrating bottom plate is slidably assembled in the sterilization kettle body, a plurality of groups of uniformly distributed ultraviolet sterilization lamp groups are fixedly assembled on the upper surface of the interpenetrating bottom plate, protective covers are fixedly sleeved on the outer sides of the plurality of groups of ultraviolet sterilization lamp groups, a vibration corrugated ring is fixedly connected to the lower surface of the interpenetrating bottom plate, and a driving corrugated ring is rotatably assembled below the vibration corrugated ring.

[0011] The pulsed material turning mechanism is assembled in the sterilization kettle body. The pulsed material turning mechanism is used to assist the interpenetrating multi-directional sterilization mechanism to perform turning and comprehensive sterilization of agricultural products. The pulsed material turning mechanism includes a material turning limit pad, the material turning limit pad is fixedly connected to the inner wall of the sterilization kettle body, and a supporting material turning unit is arranged below the material turning limit pad.

[0012] In one or more embodiments of the present invention, a kettle cover is fixedly connected above the sterilization kettle body. A semi-closed sterilization treatment cavity is formed by the cooperation of the kettle cover, the sterilization kettle body, and the material turning limit pad, reducing the adverse effects of the environment on the sterilization effect of the agricultural products to be processed. A feeding pipe is fixedly communicated above the kettle cover. The agricultural products to be processed are added into the sterilization kettle body through the feeding pipe. A guiding cone is fixedly connected inside the kettle cover. The guiding cone is used to guide the agricultural products to be processed added at the feeding pipe. Through the guiding of the guiding cone, the agricultural products to be processed can be prevented from colliding and impacting the protective cover, extending the service life of the protective cover. At the same time, by arranging the agricultural products to be processed around through the guiding cone, the situation of accumulation at the central position of the agricultural products to be processed is avoided.

[0013] In one or more embodiments of the present invention, a heat-conducting reflective inner ring is fixedly connected to the inner wall of the sterilization kettle body. A heat-conducting cavity is formed by the heat-conducting reflective inner ring and the sterilization kettle body. At the same time, the ultraviolet rays generated by the multiple groups of ultraviolet sterilization lamps can be refracted by the heat-conducting reflective inner ring, which not only improves the effect of multi-angle irradiation and sterilization of the agricultural products to be processed in the sterilization kettle body, reduces the operating power of the ultraviolet sterilization lamp group, but also assists in maintaining the temperature of the sterilization kettle body, and pasteurizes the agricultural products to be processed in the sterilization kettle body. A heat-conducting cavity is formed between the heat-conducting reflective inner ring and the sterilization kettle body. The temperature of the sterilization kettle body is adjusted by conveying heat-conducting gas or liquid into the heat-conducting cavity, so as to facilitate pasteurization of the agricultural products to be processed in the sterilization kettle body. A conveying joint is fixedly connected to one side of the sterilization kettle body, and the conveying joint is connected to the heat-conducting cavity. Heat-conducting gas or liquid is added to the heat-conducting cavity through the conveying joint. A discharge pipe is fixedly connected to one side of the sterilization kettle body, and the discharge pipe is arranged in cooperation with the material turning limit pad. The agricultural products sterilized in the sterilizing kettle are discharged through the discharge pipe.

[0014] In one or more embodiments of the present invention, a base is fixedly installed at the bottom of the sterilization kettle body. The base supports and limits the sterilization kettle body, ensuring the stability of the sterilization kettle body. At the same time, the controller and the reducer can be assembled and limited by the base, simplifying the subsequent maintenance process of the controller and the reducer. Multiple groups of controllers are fixedly installed in the base, and the multiple groups of controllers are electrically connected to the ultraviolet sterilization lamp group. The operating status of the multiple groups of ultraviolet sterilization lamp groups is independently controlled by the multiple groups of controllers. A reducer is fixedly installed in the base. The reducer plays a role of rotational driving on the rotating shaft.

[0015] In one or more embodiments of the present invention, the output shaft of the reducer is fixedly connected to a rotating shaft, the interlaced bottom plate is slidably mounted on the outside of the rotating shaft, and the driving corrugated ring is fixedly mounted on the outside of the rotating shaft. The rotating shaft drives the driving corrugated ring, the rotating shaft and the lifting auger to rotate. The outside of the rotating shaft is fixedly connected to a lifting auger, and the lifting auger is arranged between multiple groups of ultraviolet sterilization lamp groups. The agricultural products to be processed between the multiple groups of ultraviolet sterilization lamp groups are lifted and transported by the rotation of the lifting auger, further avoiding the accumulation of agricultural products to be processed in the center of the sterilization kettle body. The top of the rotating shaft is fixedly connected to a mixing rod, and the mixing rod is mounted on the outside of multiple groups of ultraviolet sterilization lamp groups. The mixing rod rotates with the rotation of the rotating shaft, so that the agricultural products to be processed outside the multiple groups of ultraviolet sterilization lamp groups can be stirred, thereby improving the efficiency of subsequent comprehensive sterilization of the agricultural products to be processed.

[0016] In one or more embodiments of the present invention, a limiting collar and a plurality of fixed connecting rings are fixedly connected inside the turnover limiting pad, and the limiting collar is rotatably sleeved outside the rotating shaft. The limiting collar is used to connect and limit the turnover limiting pad and the rotating shaft. A plurality of the fixed connecting rings are fixedly sleeved outside a plurality of protective covers. The fixed connecting rings are used to fixedly connect the turnover limiting pad and the protective covers, so that the turnover limiting pad can be lifted synchronously with the lifting of the protective covers under the action of the fixed connecting rings. A plurality of uniformly distributed turnover exhaust micro-holes are formed in each of the fixed connecting rings. This facilitates the air in the pulse air cavity to be conveyed to the inside of the sterilization kettle body along the turnover exhaust micro-holes. This can not only assist in turning over the products to be processed around the protective cover, but also assist in dissipating heat from the protective cover by blowing air, thus avoiding the overheating of the ultraviolet germicidal lamp group during use.

[0017] In one or more embodiments of the present invention, the turnover limiting pad and the inserted bottom plate cooperate to form a pulse air cavity, and a plurality of the turnover exhaust micro-holes are all communicated with the pulse air cavity. The supporting turnover unit includes a plurality of compression air cylinders. The compression air cylinders play a role in assembling and guiding the sliding of the piston rods. The bottoms of a plurality of the compression air cylinders are fixedly connected with assembling bottom plates, and the assembling bottom plates are fixedly connected with the bottom of the sterilization kettle body. The assembling bottom plates play a role in supporting and fixing the compression air cylinders.

[0018] In one or more embodiments of the present invention, piston rods are slidably assembled in a plurality of the assembling bottom plates, and one end of each piston rod outside the assembling bottom plate is fixedly connected with the bottom of the inserted bottom plate. The piston rods are used to assist in supporting and limiting the inserted bottom plate, thus avoiding the situation that the inserted bottom plate rotates with the rotation of the rotating shaft. At the same time, the compression air cavity can be reciprocally compressed by the way that the piston rods rise and fall with the rise and fall of the inserted bottom plate. Exhaust flow channels are formed in a plurality of the piston rods. The exhaust flow channels and the assembling exhaust holes cooperate to communicate the one-way exhaust valves and the compression air cavity.

[0019] In one or more embodiments of the present invention, a plurality of uniformly distributed assembling exhaust holes are formed in the inserted bottom plate, and a plurality of the assembling exhaust holes are all communicated with the exhaust flow channels. One-way exhaust valves are fixedly assembled above a plurality of the assembling exhaust holes, and the one-way exhaust valves are communicated with the pulse air cavity. This facilitates the unidirectional discharge of the air in the compression air cavity along the one-way exhaust valves.

[0020] In one or more embodiments of the present invention, a return spring is fixedly connected between the piston rod and the assembly base plate. The piston rod is supported and reset by the contraction and reset of the return spring. A compression air chamber is formed by the cooperation between the piston rod and the assembly base plate, and the return spring is disposed in the compression air chamber. One side of the assembly base plate is fixedly connected with a one-way intake valve, and the one-way intake valve is communicated with the compression air chamber. This allows external air to flow back into the compression air chamber along the one-way intake valve, facilitating the reset of the piston rod under the action of the return spring.

[0021] Compared with the prior art, by setting an interspersed multi-directional sterilization mechanism, multiple groups of ultraviolet sterilization devices are arranged in the agricultural products to be processed in a lifting and interspersed manner, which can assist in turning over the agricultural products to be processed, significantly improving the sterilization efficiency and comprehensiveness.

[0022] By setting a pulse-type turning-over mechanism, it can assist in turning over the agricultural products to be processed and assist in dissipating heat from the ultraviolet sterilization device, greatly improving the use stability of the agricultural product processing and sterilization device.

Detailed implementation manners

[0036] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 10 shown, a sterilization device for agricultural product processing in an embodiment of the present invention includes: a sterilization kettle body 1, an interspersed multi-directional sterilization mechanism 2, and a pulse type material turning mechanism 3.

[0038] As Figure 10 shown, a kettle cover 101 is fixedly connected above the sterilization kettle body 1. Through the cooperation of the kettle cover 101, the sterilization kettle body 1 and the material turning limit pad 301, a semi-closed sterilization treatment cavity is formed, reducing the adverse effects of the environment on the sterilization effect of the agricultural products to be processed.

[0039] like Figure 10 As shown, a feeding pipe 102 is fixedly connected to the top of the kettle cover 101. The farm products to be processed are added into the sterilizing kettle body 1 through the feeding pipe 102.

[0040] like Figures 1 to 4 As shown, a guide cone 103 is fixedly connected to the kettle cover 101. The guide cone 103 guides the agricultural products to be processed added at the feeding pipe 102, and the guide cone 103 can prevent the agricultural products to be processed from colliding with the protective cover 203, thereby extending the service life of the protective cover 203. At the same time, the agricultural products to be processed are arranged around the guide cone 103, thereby avoiding the accumulation of agricultural products to be processed in the center.

[0041] like Figure 1 As shown, a heat-conducting reflective inner ring 104 is fixedly connected to the inner wall of the sterilizing kettle body 1. The heat-conducting reflective inner ring 104 cooperates with the sterilizing kettle body 1 to form a heat-conducting cavity 105. At the same time, the ultraviolet rays generated by the multiple groups of ultraviolet sterilization lamp groups 202 can be refracted by the heat-conducting reflective inner ring 104, which not only improves the effect of multi-angle irradiation and sterilization of the agricultural products to be processed in the sterilizing kettle body 1, reduces the operating power of the ultraviolet sterilization lamp group 202, but also assists in maintaining the temperature of the sterilizing kettle body 1, and can pasteurize the agricultural products to be processed in the sterilizing kettle body 1.

[0042] Specifically, a heat-conducting cavity 105 is formed between the heat-conducting reflective inner ring 104 and the sterilizing kettle body 1. The temperature of the sterilizing kettle body 1 is adjusted by conveying heat-conducting gas or liquid into the heat-conducting cavity 105, thereby facilitating pasteurization of the agricultural products to be processed in the sterilizing kettle body 1.

[0043] like Figure 1 As shown, a delivery joint 106 is fixedly connected to one side of the sterilization kettle body 1, and the delivery joint 106 is connected to the heat conduction cavity 105. Heat conduction gas or liquid is added into the heat conduction cavity 105 through the delivery joint 106.

[0044] like Figure 10 As shown, a discharge pipe 107 is fixedly connected to one side of the sterilizing kettle body 1, and the discharge pipe 107 is arranged in cooperation with the turning limit pad 301. The sterilized agricultural products in the sterilizing kettle body 1 are discharged through the discharge pipe 107.

[0045] It is worth noting that, during actual use, the discharge pipe 107 may be externally connected to a stop valve for controlling the conduction state of the discharge pipe 107 .

[0046] like Figures 1 to 5As shown in the figure, the interspersed multi-directional sterilization mechanism 2 is assembled inside the sterilization kettle body 1. The interspersed multi-directional sterilization mechanism 2 is used for lifting, vibrating, stirring and mixing the sterilization treatment of agricultural products. The interspersed multi-directional sterilization mechanism 2 includes an interspersed bottom plate 201, and the interspersed bottom plate 201 is slidably assembled inside the sterilization kettle body 1. The assembly and limitation of multiple groups of ultraviolet sterilization lamp groups 202 are carried out through the interspersed bottom plate 201. At the same time, by controlling the reciprocating lifting of multiple groups of ultraviolet sterilization lamp groups 202, multiple groups of ultraviolet sterilization lamp groups 202 can be driven to reciprocally penetrate into the agricultural products to be processed.

[0047] It should be noted that during the penetration process of multiple groups of ultraviolet sterilization lamp groups 202, not only can the agricultural products to be processed around the protective cover 203 be assisted in guiding the flow, but also the multiple groups of ultraviolet sterilization lamp groups 202 can perform multi-angle sterilization on the agricultural products to be processed.

[0048] As Figures 1 to 2 shown in the figure, multiple groups of evenly distributed ultraviolet sterilization lamp groups 202 are fixedly assembled on the upper surface of the interspersed bottom plate 201. By controlling the operation of multiple groups of ultraviolet sterilization lamp groups 202, ultraviolet irradiation sterilization treatment is carried out on the agricultural products to be processed inside the sterilization kettle body 1.

[0049] As Figures 4 to 5 shown in the figure, protective covers 203 are fixedly sleeved on the outer sides of multiple groups of ultraviolet sterilization lamp groups 202. The ultraviolet sterilization lamp groups 202 are protected by the protective covers 203, avoiding the damage of multiple groups of ultraviolet sterilization lamp groups 202 due to external forces during use, and extending the service life of the ultraviolet sterilization lamp groups 202.

[0050] As Figures 6 to 9 shown in the figure, a vibration corrugated ring 204 is fixedly connected to the lower surface of the interspersed bottom plate 201, and a driving corrugated ring 205 is rotatably assembled below the vibration corrugated ring 204. Through the cooperation of the driving corrugated ring 205 and the vibration corrugated ring 204, the interspersed bottom plate 201 can reciprocally lift along with the rotation of the driving corrugated ring 205.

[0051] As Figure 1 shown in the figure, a base 206 is fixedly assembled at the bottom of the sterilization kettle body 1. The base 206 plays a role in supporting and limiting the sterilization kettle body 1, ensuring the use stability of the sterilization kettle body 1. At the same time, the controller 207 and the reducer 208 can be assembled, limited and protected through the base 206, simplifying the subsequent maintenance process of the controller 207 and the reducer 208.

[0052] As Figure 1 shown in the figure, multiple groups of controllers 207 are fixedly assembled inside the base 206, and multiple groups of controllers 207 are electrically connected to the ultraviolet sterilization lamp groups 202. The operation states of multiple groups of ultraviolet sterilization lamp groups 202 are independently controlled through multiple groups of controllers 207.

[0053] As Figure 6 shown, a speed reducer 208 is fixedly assembled inside the base 206. The speed reducer 208 plays a role in rotating and driving the rotating shaft 209.

[0054] As Figures 1 to 2 shown, the output shaft of the speed reducer 208 is fixedly connected to a rotating shaft 209. The inserting bottom plate 201 is slidably sleeved outside the rotating shaft 209, and the driving corrugated ring 205 is fixedly sleeved outside the rotating shaft 209. The rotating shaft 209 rotates and drives the driving corrugated ring 205, the rotating shaft 209 and the lifting auger 210.

[0055] As Figure 4 shown, a lifting auger 210 is fixedly connected to the outside of the rotating shaft 209. The lifting auger 210 is arranged between multiple groups of ultraviolet germicidal lamp groups 202. By rotating the lifting auger 210, the agricultural products to be processed between multiple groups of ultraviolet germicidal lamp groups 202 are lifted and conveyed, further avoiding the situation that the agricultural products to be processed accumulate at the central position of the sterilization kettle body 1.

[0056] As Figure 4 shown, a mixing rod 211 is fixedly connected to the top end of the rotating shaft 209. The mixing rod 211 is sleeved outside multiple groups of ultraviolet germicidal lamp groups 202. By rotating the mixing rod 211 along with the rotation of the rotating shaft 209, the agricultural products to be processed outside multiple groups of ultraviolet germicidal lamp groups 202 can be stirred, improving the efficiency of subsequent comprehensive sterilization of the agricultural products to be processed.

[0057] As Figures 1 to 4 shown, a pulse type turning mechanism 3 is assembled inside the sterilization kettle body 1. The pulse type turning mechanism 3 is used to assist the inserted multi-directional sterilization mechanism 2 to perform turning type comprehensive sterilization on agricultural products. The pulse type turning mechanism 3 includes a turning limit pad 301, and the turning limit pad 301 is fixedly connected to the inner wall of the sterilization kettle body 1. By cooperating with the sterilization kettle body 1 through the turning limit pad 301, the agricultural products to be processed are assisted in being supported, avoiding interference between the inserting bottom plate 201 and the agricultural products to be processed during the reciprocating lifting process. At the same time, by controlling the turning limit pad 301 to lift along with the reciprocating lifting of the protective cover 203, the agricultural products to be processed supported on the turning limit pad 301 can be assisted in turning, greatly improving the efficiency of sterilizing the agricultural products to be processed.

[0058] As Figures 4 to 5 shown, a limit sleeve ring 302 and multiple fixed connection rings 303 are fixedly connected inside the turning limit pad 301. The limit sleeve ring 302 is rotatably sleeved outside the rotating shaft 209. The turning limit pad 301 and the rotating shaft 209 are connected and limited through the limit sleeve ring 302.

[0059] It should be noted that multiple fixed connecting rings 303 are fixedly sleeved on the outer sides of multiple protective covers 203. The turning material limiting pad 301 and the protective cover 203 are fixedly connected through the fixed connecting ring 303, so that the turning material limiting pad 301 can be lifted and lowered synchronously with the lifting of the protective cover 203 under the action of the fixed connecting ring 303.

[0060] Specifically, multiple turning material exhaust micropores are uniformly distributed in each of the multiple fixed connecting rings 303. This facilitates the air in the pulse air cavity 304 to be transported into the sterilization kettle body 1 along the turning material exhaust micropores. It can not only assist in turning the products to be processed around the protective cover 203, but also assist in dissipating heat from the protective cover 203 by blowing air, avoiding the overheating of the ultraviolet germicidal lamp group 202 during use.

[0061] As Figures 1 to 2 shown, the turning material limiting pad 301 and the inserted bottom plate 201 cooperate to form a pulse air cavity 304, and multiple turning material exhaust micropores are all communicated with the pulse air cavity 304.

[0062] As Figures 1 to 3 shown, a supporting turning unit is arranged below the turning material limiting pad 301. The supporting turning unit includes multiple compression air cylinders 305. The compression air cylinders 305 play a role in assembling and guiding the sliding of the piston rod 307. The bottoms of multiple compression air cylinders 305 are fixedly connected with an assembly bottom plate 306, and the assembly bottom plate 306 is fixedly connected with the bottom of the sterilization kettle body 1. The assembly bottom plate 306 plays a role in supporting and fixing the compression air cylinders 305.

[0063] As Figures 8 to 9 shown, piston rods 307 are slidably assembled in each of the multiple assembly bottom plates 306, and one end of the piston rod 307 outside the assembly bottom plate 306 is fixedly connected with the bottom of the inserted bottom plate 201. The inserted bottom plate 201 is assisted in supporting and limiting through the piston rod 307, avoiding the situation that the inserted bottom plate 201 rotates with the rotation of the rotating shaft 209. At the same time, the compression air cavity can be reciprocally compressed by the piston rod 307 rising and falling with the rising and falling of the inserted bottom plate 201.

[0064] Among them, exhaust flow channels 308 are provided in each of the multiple piston rods 307. The one-way exhaust valve 310 and the compression air cavity are communicated through the cooperation of the exhaust flow channels 308 and the assembly exhaust holes 309.

[0065] Specifically, multiple assembly exhaust holes 309 are uniformly distributed on the inserted bottom plate 201, and multiple assembly exhaust holes 309 are all communicated with the exhaust flow channels 308.

[0066] As Figures 1 to 3As shown, a one-way exhaust valve 310 is fixedly assembled above each of the multiple assembly exhaust holes 309. The one-way exhaust valve 310 is in communication with the pulse air chamber 304. This facilitates the one-way discharge of the compressor air chamber bore tool along the one-way exhaust valve 310.

[0067] As Figures 8 to 9 shown, a return spring 311 is fixedly connected between the piston rod 307 and the assembly bottom plate 306. The piston rod 307 is supported and reset by the contraction and reset of the return spring 311.

[0068] Specifically, a compression air chamber is formed by the cooperation between the piston rod 307 and the assembly bottom plate 306, and the return spring 311 is arranged in the compression air chamber.

[0069] As Figures 1 to 3 shown, a one-way intake valve 312 is fixedly connected to one side of the assembly bottom plate 306. The one-way intake valve 312 is in communication with the compression air chamber. This allows outside air to flow back into the compression air chamber along the one-way intake valve 312, thereby facilitating the reset of the piston rod 307 under the action of the return spring 311.

[0070] During specific use, the agricultural products to be processed can be added into the sterilization kettle body 1 along the feeding pipe 102. During the addition process, the agricultural products to be processed can fall into the sterilization kettle body 1 along the periphery of the sterilization kettle body 1 under the limiting and guiding action of the guiding cone 103. The guiding of the guiding cone 103 not only improves the uniformity of adding the agricultural products to be processed, but also avoids the collision and impact of the agricultural products to be processed with the multiple protective covers 203.

[0071] Subsequently, the ultraviolet germicidal lamp group 202 can be controlled to operate by multiple controllers 207 to generate ultraviolet rays, and the agricultural products to be processed in the sterilization kettle body 1 can be irradiated and sterilized by irradiating the agricultural products to be processed with ultraviolet rays. At the same time, during the sterilization process, the reduction gear 208 can be controlled to operate to drive the rotating shaft 209 to rotate. During the rotation of the rotating shaft 209, the driving corrugated ring 205 can be driven to rotate, so that the insertion bottom plate 201 reciprocates up and down under the combined action of the vibration corrugated ring 204 and the driving corrugated ring 205. By reciprocating up and down the insertion bottom plate 201, the multiple protective covers 203 can be driven to perform an interspersed irradiation sterilization on the agricultural products to be processed.

[0072] During the reciprocating lifting process of multiple groups of protective covers 203, the agricultural products to be processed near the multiple groups of protective covers 203 can be disturbed. At the same time, by rotating the lifting auger 210, the agricultural products to be processed between the multiple groups of protective covers 203 can be lifted and dispersed, avoiding the accumulation of the agricultural products to be processed at the central position of the sterilization kettle body 1. In addition, the rotation of the mixing rod 211 can assist in agitating the agricultural products to be processed outside the multiple groups of protective covers 203, greatly improving the comprehensiveness and efficiency of irradiating and sterilizing the agricultural products to be processed.

[0073] In addition, during the reciprocating lifting process of multiple groups of protective covers 203, the turning limit pad 301 can be driven to perform reciprocating lifting and resetting under the action of the fixed connecting ring 303, so that the agricultural products to be processed placed on the turning limit pad 301 can be pulled and turned, further improving the comprehensiveness of the ultraviolet sterilization lamp group 202 irradiating and sterilizing the agricultural products to be processed.

[0074] Furthermore, during the reciprocating lifting process of the inserted bottom plate 201, the controller 207 can be driven to reciprocally compress the mixing rod 211. When the controller 207 compresses the mixing rod 211, the air in the compression air cavity will be transported to the pulse air cavity 304 along the exhaust flow channel 308, the assembled exhaust hole 309, and the one-way exhaust valve 310, and the air in the pulse air cavity 304 will be discharged through the turning exhaust micro-holes on the fixed connecting ring 303. The method of exhausting air through the turning exhaust micro-holes can not only assist in turning the agricultural products to be processed, but also blow air to dissipate heat and cool down the protective cover 203, extending the service life of the ultraviolet sterilization lamp group 202.
