An example of a stirring tank (10, 30) with 34) is shown. The structure of a conventional stirrer will be briefly described with reference to FIGS. 1a and 1b.

The stirrer (10) of FIG. 1a illustrates a rotor (14) that rotates vertically within a stirring tank (12) by a horizontal axis of rotation (16), which is placed in the tank (12). Stirrer with raw garbage and base material (14)
It has the characteristic of stirring in the clockwise direction (direction of arrow A).

In addition, in the agitator (30) of FIG. 1b, the surface of the rotating column (38) formed vertically in the agitating tank (32) has a spiral blade (3).
4) is illustrated, and the stirring blade (34) is characterized by being driven by rotation of a rotating shaft (36) connected to a rotating column (38). Figure 1b
In the stirrer (30), the spiral stirring blade (4) rotates as the rotating shaft (36) rotates (direction of arrow C) to stir the mixture (20) of food waste and base material. That is, the mixture (20) around the rotating column (38)
Is raised in the upward direction (arrow B direction) by the rotation of the spiral stirring blade (34) and the mixture (20) next to it fills the trace repeatedly, so that the raw waste and the base material put into the stirrer are equalized. Is stirred.

[0006] In this way, the raw garbage thrown into the agitator is pre-built before foreign substances such as metal objects and vinyl are removed, but when foreign substances remain in the raw garbage actually thrown in. There are many. If this residual foreign matter is thrown into the stirrer together with the garbage, metal objects and other foreign matter may contact the stirrer blade to damage the stirrer blade or become entangled with the stirrer blade and significantly reduce the stirring efficiency.

Further, this method has a defect that it cannot be increased in size for treating a large amount of garbage. The reason is that in order to efficiently mix the raw dust and the base material in the agitator, the agitating blade is made to have a size corresponding to the agitating tank. It is not possible to stir the garbage. The stirring blade often breaks due to the load and viscosity of raw garbage, and even if the stirring blade is forcibly strengthened, the stirring becomes rough and not evenly stirred, resulting in a significant decrease in stirring efficiency. .
