The feeder 1 and the discharger 3 are respectively arranged at the inlet and outlet ends of the irregularly shaped conveyor belt 21, while the middle part forms a vertical spiral shape passing through the sterilization equipment. The central control device is electrically connected to the feeder 1, the spiral conveyor tower 2, the discharger 3, and the sterilization equipment. Specifically, the belt body 211 of the irregularly shaped conveyor belt 21 is a mesh belt and can be divided into a straight feeding section 2 that connects to the feeder 1. 111. The feeding straight section 2113 (the position of the feeding straight section 2113 is higher than the position of the feeding straight section 2111), the spiral rising section 2122 that spirals from the feeding straight section 2111 to the feeding straight section 2111, and the return section 2114 that returns from the feeding straight section 2111 to the feeding straight section 2113 can effectively save space and achieve the goal of small area and large capacity. In addition, the number of layers of the spiral rising section 2122 can be set to 3 to 8 layers (preferably 5 layers), and the pitch is controlled at 200 to 400 mm (preferably 300 mm).

[0029] Referring to Figure 9 The guide roller 2123 comprises a guide wheel 21231, a guide shaft 21232 and a guide seat 21233, the guide wheel 21231 is coaxially arranged with the guide shaft 21232, the guide shaft 21232 is rotatably connected to the guide seat 21233, and the guide seat 21233 is detachably connected to the tower body support frame 22; specifically, the guide seat 21233 is threadedly connected to the tower body support frame 22 through fasteners.

[0030] In addition, in actual arrangement, the spiral conveying tower 2 and the sterilization equipment can be arranged in the same room separately, and the feeding machine 1 and the discharging machine 3 are arranged in other rooms respectively (for example, the discharging flat section 2113 penetrates through the wall of the room where it is located, so that the discharging machine 3 is in the next room).

[0031] Working process of the present application: Before use, the swinging amplitude of the belt body 211 can be adjusted according to requirements; specifically, the two base plates 21221 are first fastened at a proper height by means of fasteners, and then the two blocking rods 21222 are screwed onto the corresponding base plates 21221 by means of fasteners, so as to restrict the movable shaft 21212 in a specified length section of the through slot 21241 by the two blocking rods 21222 one above the other (i.e. the shaking driver 213 can only drive the movable roller 2121 and the belt body 211 outside the movable roller 2121 to swing back and forth in the specified length section of the through slot 21241); in addition, after the position adjustment of the position limiter 2122 is completed, the mounting height of each guide roller 2123 can also be adjusted by means of fasteners.
