Description

Technical Field

[0001] This invention relates to the field of grain storage technology, and in particular to a grain spiral sterilization device. Background Technology

[0002] Currently, to ensure the quality and safety of grains during storage and packaging, all grains undergo a crucial sterilization process before formal storage and packaging. This carefully designed step not only effectively extends the overall shelf life of grains, allowing them to maintain their original freshness and nutritional value for a longer period, but also significantly reduces the total number of bacteria within the grains. This substantially lowers the risk of mold, spoilage, and other quality problems during subsequent storage. Through this scientific and rigorous sterilization process, we can better guarantee the hygiene and safety of grains, providing consumers with healthier and more reliable food choices.

[0003] However, current grain sterilization methods all use sterilization tunnels. While the grain is being transported by a conveyor belt, it is also being sterilized by radiation lamps. This results in the grain at the bottom not being exposed to the radiation, leading to incomplete sterilization. Summary of the Invention

[0004] The main objective of this invention is to provide a grain spiral sterilization device, which can effectively solve the problem of insufficient grain sterilization at present.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A grain spiral sterilization device includes a body, in which a spiral sterilization component is installed;

[0007] The spiral sterilization component includes several spiral glass tubes and mounting columns. The mounting columns are installed inside the machine body. Each pair of spiral glass tubes is connected by a stirring component. The mounting columns are located at the center of the spiral sterilization component. Several first radiation sterilization lamps are installed on the mounting columns.

[0008] The agitation assembly includes a first connecting tube installed between two corresponding spiral glass tubes. A first annular groove is formed on the outer side of the first connecting tube, and a magnetically attracted rotating ring is rotatably installed in the first annular groove. A second annular groove is formed on the inner side of the first connecting tube, and a magnetically attracted spiral agitator is rotatably installed in the second annular groove. A magnetic ring is fitted inside the magnetically attracted rotating ring, and the magnetic ring is magnetically attracted to the magnetically attracted spiral agitator. A pulley ring is sleeved and fixed on the outer side of the magnetically attracted rotating ring. The machine body is equipped with a drive motor, a corresponding belt drive wheel, and a belt.

[0009] Preferably, a second connecting pipe is installed on the upper side of the machine body. One end of the second connecting pipe is connected to the upper end of the spiral sterilization component, and a bag filter is installed on the other end of the second connecting pipe. An ozone recovery device is installed in the air outlet of the bag filter in conjunction with the main pipe. An ash discharge pipe is installed at the lower end of the bag filter and extends out of the machine body.

[0010] Preferably, the lower end of the spiral sterilization component is fitted with a grain outlet pipe, and an ozone inlet pipe is fitted on the grain outlet pipe. The spiral glass tube is provided with several stirring columns.

[0011] Preferably, a dustproof plate is provided at one end of the ozone inlet pipe that is installed in conjunction with the grain outlet pipe.

[0012] Preferably, a number of filter plates are installed inside the ozone inlet pipe.

[0013] Preferably, a grain conveying channel is installed on the second connecting pipe, the grain conveying channel is inclined, and a feed hopper is installed at the upper end of the grain conveying channel.

[0014] Preferably, a plurality of second radiation sterilization lamps are installed in the grain conveying channel. The second radiation sterilization lamps are arranged in a linear array and are fitted with dustproof glass tubes.

[0015] Preferably, a first mounting frame is installed inside the machine body, and a plurality of third radiation germicidal lamps are installed on the first mounting frame, the third radiation germicidal lamps being arranged around the spiral sterilization component.

[0016] Preferably, a second mounting bracket is installed inside the machine body, and a shock-absorbing pad is installed on the second mounting bracket. The shock-absorbing pad has a mounting groove.

[0017] Preferably, a third mounting bracket is fitted onto the spiral glass tube, and a plurality of reflectors are fitted onto the outer side of the third mounting bracket. The plurality of reflectors form a reflector tube, which is fitted into a mounting slot. A plurality of fourth radiation germicidal lamps are fitted onto the third mounting bracket, and a light-diffusing plate is fitted onto the inner side of the third mounting bracket. The light-diffusing plate is located between the fourth radiation germicidal lamps and the spiral glass tube.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The mounting column in this invention is equipped with several high-efficiency radiation germicidal lamps. These lamps are designed to significantly reduce the number of bacterial colonies carried in grains through radiation sterilization technology. This innovative solution not only significantly extends the shelf life of grains but also substantially improves their storage safety, greatly reducing the risk of food spoilage caused by bacterial growth. Particularly noteworthy is the irregular agitation effect that occurs naturally as the grains slowly fall along the spiral glass tube, ensuring that each grain receives uniform and sufficient omnidirectional irradiation from the first radiation germicidal lamp. This design cleverly utilizes the principles of physical motion to achieve a comprehensive upgrade in sterilization effect, ensuring maximum coverage of the sterilization range without missing any grains, thereby greatly improving the overall efficiency and effectiveness of sterilization. In summary, this invention provides solid technical support for the long-term safe storage of grains, effectively protecting food safety and consumers' health rights.

[0020] 2. This invention achieves precise control of the magnetic rotating ring through a drive motor, corresponding belt drive pulleys, and a high-efficiency transmission belt system, driving its smooth and efficient rotation. This mechanical linkage mechanism further causes the magnetic ring to rotate accordingly, and the rotation of the magnetic ring drives the synchronous rotation of the magnetic spiral stirring rod. The rotation of the magnetic spiral stirring rod achieves meticulous turning of the grain. This dynamic process not only enhances the interaction between grain particles, but more importantly, ensures that each grain receives more even and intense irradiation from the first radiation sterilization lamp. This greatly improves the uniformity and efficiency of radiation sterilization, further significantly reducing the total amount of bacteria in the grain, thereby fundamentally improving the hygienic quality of the grain. In summary, this invention significantly extends the shelf life of grain and substantially enhances its safety, providing consumers with a more reliable and healthier food choice.

[0021] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. Attached Figure Description

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] like Figure 1-12 As shown, the grain spiral sterilization device includes a body 108, and a spiral sterilization component 400 is installed inside the body 108.

[0041] The spiral sterilization component 400 includes several spiral glass tubes 101 and mounting columns 106. The mounting columns 106 are installed inside the body 108. Each pair of spiral glass tubes 101 is connected by a stirring component 200. The mounting column 106 is located at the center of the spiral sterilization component 400. Several first radiation sterilization lamps 107 are installed on the mounting column 106.

[0042] The first radiation sterilization lamp 107 is evenly installed on the mounting column 106, which can effectively perform radiation sterilization on the grain in the transparent spiral glass tube 101, further reducing the total number of colonies in the grain, thereby greatly improving the storage time and safety of the grain and reducing the risk of consumption. When the grain falls in the spiral glass tube, it will be irregularly turned over, so that each grain will be irradiated by the first radiation sterilization lamp, thereby improving the effect of area sterilization.

[0043] The stirring assembly 200 includes a first connecting pipe 201, which is installed between two corresponding spiral glass tubes 101. A first annular groove 204 is provided on the outer side of the first connecting pipe 201. A magnetic rotating ring 202 is rotatably installed in the first annular groove 204. A second annular groove 206 is provided on the inner side of the first connecting pipe 201. A magnetic spiral stirring rod 207 is rotatably installed in the second annular groove 206. A magnetic ring 205 is installed in the magnetic rotating ring 202. The magnetic ring 205 and the magnetic spiral stirring rod 207 are magnetically attracted to each other. A pulley ring 203 is sleeved and fixed on the outer side of the magnetic rotating ring 202. The machine body 108 is provided with a drive motor, a corresponding belt drive wheel and belt.

[0044] In this embodiment, the first connecting pipe 201 is made of insulating material, which effectively increases the magnetic attraction between the magnetic ring 205 and the magnetic spiral stirring rod 207. The drive motor, the corresponding belt drive wheel and belt are all commonly used existing technologies and are not shown in the figure. The drive motor, the corresponding belt drive wheel and belt can control the magnetic rotating ring 202 to rotate, thereby causing the magnetic ring 205 to rotate. The rotating magnetic ring 205 drives the magnetic spiral stirring rod 207 to rotate, thereby turning the grain, so that the grain is irradiated more evenly by the first radiation sterilization lamp 107, further reducing the total number of colonies in the grain, and thus greatly improving the storage time and safety of the grain.

[0045] A second connecting pipe 103 is installed on the upper side of the body 108. One end of the second connecting pipe 103 is connected to the upper end of the spiral sterilization component 400, and the other end of the second connecting pipe 103 is installed with a bag filter 301. The air outlet of the bag filter 301 is connected with an ozone recovery device 302. The lower end of the bag filter 301 is installed with an ash discharge pipe 303, which extends out of the body 108.

[0046] In this embodiment, the bag filter 301 can effectively absorb dust in the grain. The bag filter 301 has a high-power air extraction function, which can effectively recover dust in the grain. When a large flow of air circulates in the spiral glass tube 101, it can also agitate the grain. When the grain is agitated by the magnetic spiral stirring rod 207, more dust is transported upward to the bag filter 301 for dust removal, thereby further improving the dust removal effect.

[0047] A dustproof plate 110 is provided at one end of the ozone inlet pipe 109 that is installed in conjunction with the grain outlet pipe 102. Several filter plates 112 are installed inside the ozone inlet pipe 109. The grain outlet pipe 102 is installed at the lower end of the spiral sterilization component 400. The ozone inlet pipe 109 is installed on the grain outlet pipe 102. Several stirring columns 111 are provided inside the spiral glass tube 101. In this embodiment, the installation of stirring columns 111 can cause the grain to turn over inside the spiral glass tube 101, thereby improving the sterilization effect.

[0048] A grain conveying channel 104 is installed on the second connecting pipe 103. The grain conveying channel 104 is inclined and a feed hopper 105 is installed at the upper end of the grain conveying channel 104. Several second radiation sterilization lamps 113 are installed inside the grain conveying channel 104. The second radiation sterilization lamps 113 are arranged in a linear array and are fitted with dustproof glass tubes 114. The second radiation sterilization lamps 113 can perform a radiation sterilization operation on the grain when the grain passes through the grain conveying channel 104, further reducing the number of bacteria in the grain.

[0049] like Figure 13-14 As shown, in another embodiment of this application, based on the above embodiment, a first mounting frame 115 is also installed in the body 108, and a plurality of third radiation germicidal lamps 122 are installed on the first mounting frame 115, the third radiation germicidal lamps 122 being arranged around the spiral sterilization component 400.

[0050] In this embodiment, the grain is subjected to multiple rounds of radiation sterilization by the first radiation sterilizing lamp 107, the second radiation sterilizing lamp 113 and the third radiation sterilizing lamp 122, which effectively reduces the number of bacteria in the grain and further improves the safety of the grain.

[0051] like Figure 15-16 As shown, in another embodiment of this application, based on the first embodiment, a second mounting bracket 116 is installed inside the body 108, and a shock-absorbing pad 117 is installed on the second mounting bracket 116. The shock-absorbing pad 117 has a mounting groove 123. A third mounting bracket 118 is sleeved on the spiral glass tube 101. A plurality of reflectors 119 are installed on the outside of the third mounting bracket 118, and the plurality of reflectors 119 form a reflector tube. The reflector tube is configured to cooperate with the mounting groove 123. A plurality of fourth radiation germicidal lamps 120 are installed on the third mounting bracket 118, and a light-diffusing plate 121 is installed on the inside of the third mounting bracket 118. The light-diffusing plate 121 is located between the fourth radiation germicidal lamps 120 and the spiral glass tube 101. In actual production, the light-diffusing plate 121 is installed as an optional accessory.

[0052] In this embodiment, the mounting groove 123 on the shock-absorbing pad 117 can effectively absorb the vibration generated by the spiral glass tube 101, preventing problems such as loosening of the interface of the spiral glass tube 101, and further improving the safety of this embodiment. In addition, the fourth radiation germicidal lamp 120 of this application is installed around the spiral glass tube 101, and the radiation germicidal lamp emitted by the fourth radiation germicidal lamp 120 can directly penetrate into the spiral glass tube 101, reducing the loss of radiation sterilization and further improving the sterilization effect.
