Referring to fig. 5 and 11, the blade 42 of the stirring impeller 40 of the present embodiment includes a blade main body 420, a first bending portion 421 and a second bending portion 422, the blade main body 420 is a flat strip-shaped sheet body, wherein the middle portion of the blade main body 420 is connected to the upper end surface of the rotating shaft 41 through a screw 43, wherein a second positioning groove 412 is radially disposed on the upper end surface of the rotating shaft 41 along the upper end surface, the width of the second positioning groove is substantially consistent with the width of the blade main body, so that the blade main body can be limited in the second positioning groove 412, and the problem of looseness in the circumferential direction of the rotating shaft 41 is avoided.

One free end of the first bending portion 421 is bent upward, and the second bending portion 422 is bent downward from the other free end of the blade body. A first bending line 4210 is formed between the first bending portion 421 and the blade body 420, an extending direction of the first bending line 4210 and a length direction a1 of the blade body 420 are distributed in an inclined manner, and the first bending portion 421 is inclined from bottom to top in a direction away from the rotating shaft 41. A second bending line 4220 is formed between the second bending portion 422 and the blade body 420, and the extending direction of the second bending line 4220 is inclined to the length direction a1 of the blade 42, specifically, the extending plane of the second bending portion 422 is substantially perpendicular to the horizontal plane.

The heating device of the fermentation device is a heating panel 12, which can be arranged on the inner wall of the installation groove 15 of the inner lining 101. After the fermentation box 20 is placed in place, the heating panel 12 can be attached to and contacted with the outer surface of the side wall of the fermentation box 20, so that the fermentation box 20 is heated, and the fermentation efficiency is improved.

The fermentation apparatus further comprises a suction pump 17. The air pump 17 can be disposed in the inner lining plate 101 of the garbage disposal apparatus, wherein the top of the fermentation tank 20 of the fermentation device is opened with an exhaust hole 25, and the air inlet of the air pump 17 can be connected with the exhaust hole 25 through an exhaust pipe 171, so as to timely exhaust the gas generated during the fermentation process of the garbage material, as shown in fig. 12 in detail.
