The moving roller 42 can rotate around its axis. In this embodiment The linear moving mechanism 43 includes a driving motor, a lead screw and a linear guide rail. The moving drum 42 is provided with a material inlet and outlet opening 421 and a plurality of ventilation through holes 422 on its outer peripheral wall. In this embodiment, the material inlet and outlet opening 421 is in a rectangular shape, and the ventilation through holes 422 are in a circular shape. The linear moving mechanism 43 moves the moving drum 42 out of the first chamber 41 and rotates the moving drum 42 so that the inlet and outlet openings 421 face upward, and the granular food G falls from the first conveyor belt 31 into the moving drum 42 . Then the linear moving mechanism 43 makes the moving roller 42 enter the first chamber 41 , the gas generator generates sterilizing gas and delivers it to the first chamber 41 , and the moving roller 42 rotates in the first chamber 41 , and the aperture of the ventilation through hole 422 It is set to be smaller than the particle size of the granular food G. The maximum radial distance between the edge of the inlet and outlet opening 421 of the moving drum 42 and the wall surface of the first chamber 41 is smaller than the particle size of the granular food G, whereby when the granular food is Food G is on the move When rolling in the drum 42, the granular food G does not fall off from the moving drum 42. The sterilizing gas can enter the moving drum 42 through the ventilation holes 422 . The disinfecting gas in this embodiment is ozone.

When the sterilization process is completed, the linear moving mechanism 43 moves the moving drum 42 out of the first chamber 41 and rotates the moving drum 42 at the same time, so that the inlet and outlet openings 421 are directed downward toward the dispensing module 50, and the granular food G falls into 50 subassembly modules.

Please refer to Figure 9 as well. The sub-packaging module 50 includes a second conveyor belt 51 and a plurality of containers 52. The second conveyor belt 51 carries the containers 52 and moves them sequentially to the second sterilization and disinfection module 40 to contain the second container. 2. Granular food G after sterilization by the sterilization module 40. The second conveyor belt 51 in this embodiment is arranged around the first chamber 41 and the moving roller 42 of the second sterilization and disinfection module 40 . The container 52 is conveyed to the lower part of the moving drum 42 by the second conveyor belt 51 , and the granular food G falls into the container 52 . The subassembly module 50 further includes a robotic arm 53 and an air extraction device (not shown). The robotic arm 53 carries the plurality of lids 521 respectively and closes them on the container 52. The air extraction device closes the lids 521. The holding container 52 is evacuated to form a predetermined degree of vacuum, which is beneficial to preventing the preservation of the granular food G.
