In order to improve the extrusion effect, the helical blade 210 adopts a variable-pitch structure, specifically, the pitch of the helical blade 210 is sequentially reduced from bottom to top, so that when kitchen waste is conveyed upwards, the extrusion force is gradually increased due to the gradual reduction of the space, and the extrusion dehydration can be effectively realized. More preferably, because the inner wall of the solid-liquid separation barrel 400 is also provided with the cutter 500, in order to facilitate the installation of the subsequent helical blade 210 in the solid-liquid separation barrel 400, the pitch of at least the part of the helical blade 210 above the highest cutter 500 is reduced from bottom to top.

Meanwhile, the cutters 500 are matched with the helical blades 210 for shearing, so that the kitchen waste can be effectively crushed, as shown in fig. 4, a plurality of layers of cutters 500 are further arranged on the inner surface of the barrel wall of the solid-liquid separation barrel 400, each layer is provided with a plurality of cutters 500 and is uniformly distributed, preferably, each cutter 500 is four, and the number of layers of the cutters 500 is designed according to different sizes, preferably 2-4 layers. As shown in fig. 5 and 6, each of the cutting knives 500 is horizontally disposed and extends into the notch 211 formed on the spiral blade 210, and the upper and lower surfaces of the cutting knife 500 are respectively close to the upper and

lower cutting edges

212, 213 of the notch 211, so that when the spiral blade 210 rotates, the cutting knife 500 cooperates with the cutting knife 500 to form a shearing force to shear the kitchen waste to achieve crushing.
