A number of support columns connected to the ground are evenly arranged at the bottom of the shell, and a conveyor belt for conveying materials passes through the front and rear openings of the shell. A protective curtain is provided on the opening of the shell, and the top of the protective curtain is connected to the shell. There is a gap between the bottom of the protective curtain and the top of the conveyor belt. The shell is provided with a light sterilization unit, a liquid sprinkling unit and a drying unit in sequence above the conveyor belt along the material conveying direction. A plurality of bulk rollers in the horizontal direction are evenly arranged in the shell above the conveyor belt along the material conveying direction. The two ends of the bulk rollers are rotatably connected to the corresponding shaft seats on both sides of the shell. A motor is provided outside the shell, and the driving rod of the motor passes through the shell and is connected to the shaft core of the bulk roller.

When working, in order to sterilize the grains in an all-round way and improve the production quality of subsequent grain products, when the grains are added into the tank body 1, the staff starts the servo motor 4 to rotate the rotating rod 2, and the rotating rod 2 drives the spiral conveying blade 3 to rotate. At this time, the spiral conveying blade 3 turns the grains in the tank body 1 and pushes the grains upward. The grains move upward and move to the four directions under the action of the spiral conveying blade 3. Sprinkle it around, and at the same time, the staff adds disinfectant into the liquid storage tank 8 through the liquid adding pipe 9. Then the staff starts the high-pressure liquid pump 7, and pumps the disinfectant in the liquid storage tank 8 into the infusion pipe 11 through the pipette 10. Then the disinfectant enters the hollow plate 5 and is sprayed out by the array spray head 6. The mist-like disinfectant is sprayed on the grains that are constantly tumbling, and the grains are sterilized in all directions. Through the cooperation of the rotating rod 2, the spiral conveying blades 3, and the servo motor 4, the grains in the tank body 1 are constantly tumbling, which makes the sterilization of the grains more comprehensive, thereby improving the production quality of subsequent grain products.

[0024] Furthermore, a square feeding tube 12 is fixed and penetrated on one side of the top of the tank body 1, and two sets of rotating shafts 13 are arranged on the inner wall of the square feeding tube 12 in a mirror-image manner, and a baffle 14 is fixedly arranged on one side of the circumferential surface of the rotating shaft 13, and two sets of springs 15 are fixedly arranged on the opposite side of the inner wall of the square feeding tube 12 in a mirror-image manner, and the other end of the spring 15 is fixedly arranged on one side of the bottom end of the baffle 14. When working, the staff first needs to add grains into the tank body 1, and the staff puts the grains Grains are added into the tank body 1 through the square feeding tube 12. First, the initial state of the spring 15 is an uncompressed state. The grains fall onto the baffle 14, and the baffle 14 is pushed downward by gravity. The baffle 14 rotates and compresses the spring 15. The baffle 14 is opened and the grains fall into the tank body 1. After the addition is completed, the elastic potential energy of the spring 15 drives the baffle 14 to rotate, so that the two groups of baffles 14 are closed, preventing external impurities from entering the tank body 1 and preventing the disinfection mist sprayed in the tank body 1 from spreading out.

[0025] Furthermore, a cavity 16 is opened inside the shell of the tank body 1, and a heating coil 17 is fixedly installed in the cavity 16. A heat insulation layer 18 is fixedly installed on the circumferential surface of the outer wall of the tank body 1. The heat insulation layer 18 is made of mineral wool. During operation, after the disinfectant is sprayed, the staff starts the heating coil 17 to heat the tank body 1 to generate high temperature, and further sterilizes the churning grains in the tank body 1, thereby improving the sterilization effect.

The spring 15 is compressed while the baffle 14 rotates. The baffle 14 is opened and the grains fall into the tank body 1. After the addition is completed, the elastic potential energy of the spring 15 drives the baffle 14 to rotate, so that the two sets of baffles 14 are closed to prevent external impurities from entering the tank body 1 while preventing the disinfection mist sprayed in the tank body 1 from spreading. In order to enable the grains to be sterilized and disinfected in an all-round way and improve the production quality of subsequent grain products, when the grains are added into the tank body 1, the staff starts the servo motor 4 to rotate the rotating rod 2, and the rotating rod 2 drives the spiral conveying paddle 3 to rotate. At this time, the spiral conveying paddle 3 tumbles the grains in the tank body 1 and pushes the grains upward. The grains move upward under the action of the spiral conveying paddle 3 and are thrown around. At the same time, the staff sends the grains to the storage through the liquid adding tube 9. Disinfectant is added to the liquid tank 8, and then the staff starts the high-pressure liquid pump 7 to pump the disinfectant in the liquid storage tank 8 into the infusion tube 11 through the pipette 10, and then the disinfectant enters the hollow plate 5 and is sprayed out by the array spray head 6. The mist-like disinfectant is sprayed on the grains that are constantly tumbling, and the grains are sterilized and disinfected in all directions. Through the cooperation of the rotating rod 2, the spiral conveying blade 3, and the servo motor 4, the grains in the tank body 1 are constantly tumbling, so that the sterilization of the grains is more comprehensive, and the production quality of subsequent grain products is improved; when the disinfectant is sprayed, the staff starts the heating coil 17 to heat the tank body 1 to generate high temperature, and further sterilizes the tumbling grains in the tank body 1, thereby improving the sterilization effect; when the grain sterilization work is completed, the grain needs to be discharged, and at this time the staff starts the servo motor 4 to reverse, so that the spiral conveying blade 3 reverses, and the spiral conveying blade 3 drives the sterilized grains in the tank body 1 to move downward, and the valve 20 is opened, and the grains are discharged to the outside through the discharge pipe 19 for centralized collection, and the spiral conveying blade 3 improves the discharge efficiency of the grains.
