As shown in FIG. 1: in one embodiment, the feeding device 40 includes a hopper assembly for conveying the material, the hopper assembly being a large container structure for storing the material or a transit container structure for receiving a predetermined capacity, and the material can be continuously replenished to the hopper assembly. A mixing assembly is disposed within the hopper assembly and may be configured as a screw shaft or agitator shaft 121 or the like to enable directional transport of material within the hopper assembly. And, feedway 40 is including installing the sterilization subassembly in the hopper subassembly, and sterilization subassembly carries bactericidal powder to shredding barrel 11 is interior, and bactericidal powder gets into shredding barrel 11, and main shaft assembly 12 mixes bactericidal powder and material to kill the germ that carries after the material crushing. Optionally, the sterilization powder is quicklime, wherein the material conveyed by the feeding device 40 contains moisture or is added with moisture, so that the quicklime and the water are thermally sterilized. Optionally, the sterilization assembly can also be connected to the hopper assembly, so that mixing is realized in the material conveying process of the hopper assembly, and sterilization powder is conveniently added.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
