The effect that the raw material M clogged with the bottom surface of the can be easily removed is obtained.

Although the conveyor 14 shown by the solid line or the conveyor 15 shown by the alternate long and short dash line is tilted at an arbitrary angle, the angles α1 and α2 are optimally 25 °.
In addition, the traveling vehicle 3 moves forward in the arrow (c) direction and the traveling vehicle 3 moves in the arrow (d) direction.
The angles α1 and α2 may be different.

For example, the angle α1 of the conveyor 14 set when the traveling vehicle 3 advances in the arrow (c) direction, and the angle of the conveyor 15 set when traveling the traveling vehicle 3 in the arrow (d) direction. By making it smaller than α2, the raw material M can be entirely fed in the direction of the arrow (d) when the above-mentioned operations (1) and (2) are repeated, and as a result, for example, the raw material tank The raw material M charged as indicated by the symbol X on the arrow (c) side of 1 is sequentially fed in the direction of the arrow (d) while being stirred and fermented in the stirring tank 1, and further the arrow (d) of the raw material tank 1
The raw material M fermented on the side to be a fertilizer can be taken out as indicated by the symbol Y. That is, when the traveling vehicle 3 moves forward in the arrow (c) direction and when the traveling vehicle 3 moves forward in the arrow (d) direction, the angles α1 and α2 of the conveyors 14 and 15 are made different, so that the raw material M in the raw material tank 1 is changed. Since it can be sequentially transferred in the direction of the arrow (d) while stirring and fermenting, the result is that the raw material M is charged on the arrow (c) side,
The raw material M fermented into fertilizer can be taken out from the arrow (d) side, and an effect that efficient continuous production of fertilizer can be performed is obtained.
