In order to solve the above-mentioned problems, the present invention relates to an organic waste treatment apparatus, in which a stirrer is rotated by rotating a stirrer while moving in a fermenter. In the vicinity of a stand-by place of the stirrer that stirs the waste, a water jetting device that jets the washing water toward the stirrer in a standby state is provided. It is characterized in that a driving means for rotating is provided.

According to a second aspect of the present invention, there is provided the organic waste processing apparatus according to the first aspect, wherein the driving means rotates the agitating member to agitate the organic waste. It is also characterized by being used also as a driving means for driving.

The present invention is applied in the field of fermentation treatment of organic matter such as garbage and animal dung, and the object to be treated is not particularly limited. These organic substances are effectively used as compost by fermentation treatment, or are reduced in volume or eliminated to facilitate disposal, and the purpose of treatment is not limited. Further, as a typical fermentation treatment apparatus to which the present invention is applied, one having a long box-shaped fermentation tank and a scoop-type stirrer can be exemplified. In this apparatus, an organic substance is stirred by rotating a scoop while moving a scoop-type stirrer in a fermenter along the longitudinal direction of the fermenter. However, in the present invention, the shape of the fermenter and the structure of the stirrer are not limited to those described above, and a necessary shape and structure can be appropriately selected. The stirrer may be any as long as it can stir the organic matter by rotating at least the stirring member.

I do. The water injection device can be provided with a horizontally long injection port or a plurality of injection ports so as to correspond to the width of the stirring member, and can also be configured to be able to swing the injection port in the horizontal direction. In addition, when the washing water is sprayed, a driving means for rotating the stirring member is required so that the stirring member can be washed over the entire circumference of the stirring device. The rotation direction of the stirring member is not particularly limited, but it is desirable to rotate the stirring member in a direction opposite to the normal scraping direction in order to surely remove the deposits. In addition, it is desirable that the driving unit also serves as a driving unit that rotates the stirring member in order to stir the processed material. This drive means
Usually, the agitation of the processing object is interlocked with the movement of the stirrer. However, when the washing water is injected, the stirrer itself is not moved or the movement suitable for washing is performed.

When the agitating member is rotated by the driving means at the time of washing, the agitating member is rotated in accordance with the washing, so that the agitating member is rotated in conjunction with the water jet or the water is efficiently stirred. , The stirring member can be intermittently rotated, and the rotation speed of the stirring member can be adjusted according to the degree of progress of the cleaning. In these cases, a control unit for controlling the driving means can be provided. The driving means includes
A function that can change the arrangement angle of the support that supports the stirring member can also be provided. Thus, the stirring member can be rotated while being supported at a desired angle so as to increase the cleaning efficiency. This function can be originally obtained by the inclination angle adjusting means for adjusting the inclination angle by rotating the support of the stirring member at the time of stirring. Therefore, in this case, a part of the driving means of the present invention is also used as the inclination angle adjusting means. In addition, as water used for the water injection device, water such as water supply or water collected in a fermentation tank can be used, and in addition, water containing an appropriate cleaning component can also be used.
