And a fermentation decomposition chamber 4 for accommodating the organic waste treatment material 3 (hereinafter referred to as the treatment material 3) between the lower portion of the side surface of the organic waste storage chamber 2 and the lower portion of the side surface of the fermentation decomposition chamber 4. Are connected by a supply tube 8.

  The organic waste storage chamber 2 is equipped with a large hopper so that a large amount of organic waste 1 can be stored. An opening formed on the upper surface of the organic waste storage chamber 2 is covered with an organic waste charging lid (not shown). An input lid open / close detection means (not shown) for detecting opening / closing of the material input lid is provided. A screw 5 for transporting the organic waste 1 and the treatment material 3 is provided in the lower part in the organic waste storage chamber 2 so as to penetrate the supply cylinder 8.

  The screw 5 is provided with a spiral screw blade 5b on the outer periphery of a rotating shaft 5a arranged in the horizontal direction, and the screw 5 is driven by rotating the rotating shaft 5a. The organic waste 1 in the chamber 2 is conveyed along the rotating shaft 5 a, and the organic waste 1 is supplied to the fermentation decomposition chamber 4 via the supply cylinder 8.

  In addition, an organic waste crushing device 6 is provided above the screw 5 in the organic waste storage chamber 2, and the organic waste crushing device 6 is arranged on the outer periphery of a rotating shaft 6 a arranged in the horizontal direction. The paddle blade 6b for use is projected and formed. Then, by rotating the rotary shaft 6a, the paddle blade 6b crushes the organic waste 1 in the organic waste storage chamber 2, and further, on the screw 5, for example, a large vegetable such as a round vegetable such as cabbage. The state in which the organic waste 1 is not crushed due to idling is prevented.

  The screw 5 and the organic waste crushing device 6 are driven by rotating the rotary shafts 5a and 6a through the chain 20 by a charging machine driving unit 30 such as a motor.

On the other hand, the ventilation nozzle 15 on one side and the ventilation nozzle 15 on the other side have different rotation radii, and the rotation locus of each ventilation nozzle 15 passes on concentric circles having different radii. And the rotating shaft 7 rotates, and air is uniformly supplied with respect to the organic waste 1 and the processing material 3 in the circular range which the hollow pipe 14 passes. Further, the upper side and the side of the hollow pipe 14 are covered with a substantially rectangular plate-like stirring reinforcing plate 16 to ensure stirring performance during rotation.

Is formed. Therefore, the space where the organic waste 1 and the treatment material 3 do not exist is secured around the outlet of the aeration nozzle 15 at the time of agitation, and the agitation nozzle 15 can be agitated in both forward and reverse directions without clogging. The stability of processing is maintained. Moreover, the fall of the operating efficiency of the air blower 40 by clogging the ventilation nozzle 15 is also prevented, and the running cost of the air blower 40 is reduced.

  And in the upper direction of the fermentation decomposition chamber 4, the discharge blade 12 is attached to the outer periphery of the rotating shaft 7 in the horizontal direction, and when the processed material in the fermentation decomposition chamber 4 increases, the discharge blade 12 rotates, The processed product is discharged to the outside from the discharge port 4c. As shown in FIGS. 4A to 4C, the discharge blade 12 is composed of a plurality of rectangular plates, and includes two plates 12a and two plates 12b, 2 surrounding the rotating shaft 7. A single plate 12c is fixed to the rotary shaft 7 via a plurality of connecting bars 12d. The plate 12a is arranged so that each end is connected to each other and the other end sides are separated from each other, the plate 12b is arranged parallel to each other with one end connected to each other end of the plate 12a, and the plate 12c 12b is connected to each other end, and the other ends are connected to each other. That is, the discharge blade 12 is formed in a substantially hexagonal shape, and each other end of the plate 12a (one end of the plate 12b) is positioned symmetrically with respect to the center of the rotation shaft 7 to correspond to both forward and reverse rotations. The side surfaces constituted by the plates 12 a, 12 b, and 12 c have a plurality of angles with respect to the normal H of the rotating shaft 7 that passes through both ends of the discharge blade 12.

  The total length X10 of the discharge blade 12 configured in this manner is substantially equal to the inner radius of the fermentation decomposition chamber 4, and assuming that the lengths X11, X12, and X13 of the plates 12a, 12b, and 12c are X10 = X11 + X12 + X13. And X11> X12 is satisfied. That is, the plate 12a moves the processed material in the region within the radius X11 toward the outside of the rotation diameter, and the plate 12c smoothly discharges the processed material moved by the plate 12a from the discharge port 4c to the outside.

  Further, the plates 12a, 12b, and 12c are arranged at an angle θ1 = 10 ° (see FIG. 4C) with respect to the vertical direction (vertical direction) so that the side surfaces become closer to each other as it goes upward. Yes. Here, when the angle θ1 is increased, the resistance during rotation is reduced. However, when the angle θ1 is too large, the force for discharging the processed material tends to be reduced. Therefore, in this embodiment, the angle θ1 is set to 10 °. By rotating the discharge spring 12 as described above, the processed material is scraped and smoothly discharged by the rear plate with respect to the agitation direction to improve the stability of the decomposition fermentation treatment and reduce the agitation torque. . The angle θ1 may be set to another angle, and the shape of the discharge blade 12 is not limited to a hexagon. Further, if the side surfaces of the plates 12a, 12b, and 12c are separated from each other as they go upward, the resistance during rotation increases and the discharge force decreases, so that the above-described effects cannot be obtained.

  And while storing the organic waste 1 in the organic waste storage chamber 2, the odor of the organic waste 1 itself and the decaying odor due to decay may become a problem. In such a case, as shown in FIG. 1, the upper end portions of the side surfaces of the organic waste storage chamber 2 and the fermentation decomposition chamber 4 are connected by pipes 70 and face the side surfaces to which the piping 70 of the fermentation decomposition chamber 4 is connected. It is connected to the fan 60 through the deodorizer 50 from near the upper end of the surface, and the air in the fermentation decomposition chamber 4 is deodorized and discharged to the outside. At this time, since the fan 60 sucks in the air in the fermentation decomposition chamber 4, the upper portion in the fermentation decomposition chamber 4 is at a negative pressure of several tens of Pa. Therefore, the odor and decay odor in the organic waste storage chamber 2 The air containing the air is sucked into the fermentation decomposition chamber 4 through the pipe 70, deodorized by the deodorizer 50, and then discharged to the outside through the fan 60.
