When stirring the processed material in the processing tank, if the rotation direction of the stirring shaft is only one side, the processed material will be unevenly positioned in the processing tank, and the action of the stirring process will be concentrated on only a part of the processed material. It becomes difficult to efficiently process the entire processed material. Therefore, instead of setting the rotation direction of the stirring shaft to only one side, the stirring shaft can be rotationally driven to both sides of one side and the other side. For example, at a predetermined timing, the rotation direction of the stirring shaft is changed to one side. It is desired to efficiently process the entire processed material by switching from one side to the other side or from the other side to one side.

However, in the devices described in Patent Documents 1 and 2, the stirring shaft is rotated only on one side, and it is not assumed that the stirring shaft is rotated on the other side, so that the processed material is efficiently processed. It is difficult to do.

Considering scraping the adhered processed material, it is not conscious of rotating the scraping blade to the other side. Therefore, it is difficult to scrape the processed material adhering to the wall portion of the processing tank regardless of whether the scraping blade is rotated to one side or the other side.

In view of this fact, the main subject of the present invention is to drive the stirring shaft to rotate on both sides of one side and the other side, even when the stirring shaft is rotationally driven to both sides while efficiently processing the processed material. The point is to provide an organic matter processing apparatus capable of scraping off the processed material adhering to the wall portion of the processing tank.
