MIXING AGITATOR AND MIXING AGITATION DEVICE OF ORGANIC WASTE SUCH AS GARBAGE, AND COMPOSTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a mixing agitation implement and device of garbage, and a composting method which perform mixing agitation by utilizing gravity of the garbage without performing the mixing agitation by using a grinding implement or the like and can perform composting treatment even for the garbage produced in large quantity.SOLUTION: A mixing agitator 1 has stirring boxes 2 and 4 configured in two-stage stacking arrangement on the upper and lower sides. The respective stirring boxes 2 and 4 have quartered divisions in which inclination plates and discharge ports are arranged respectively in diagonal shape. Further, the inclination plates and the discharge ports are arranged in two stages on the upper and lower sides in one stirring box. On the stirring box 2 of the upper stage, the garbage is caused to roll on the inclination plate while changing a direction by 90°, thereby, is mixed and agitated and, subsequently, on the stirring box 4 of the lower stage, is further caused to roll on the inclination plate while changing the direction by 90°, thereby, is mixed and agitated and is turned into such a state that the direction is changed by 180° in total. As the result, superior mixing agitation and turn-over is performed.SELECTED DRAWING: Figure 1
