Next, the operation of the organic waste fermentation treatment system will be described.

First, in the crushing / charging step, after opening the upper lid and charging the moisture adjusting agent such as bran and bran into the processing tank 1,
The crusher 9 is stopped above the input port 14 of the processing tank 1, and the waste chicken is dropped into the processing tank 1 from the input port 14 while being crushed by the crusher 9, and then the crusher is moved to the next fermentation processing. Then, the fermentation bacteria are also charged into the processing tank 1 and then the inlet 14 is closed.

In each of the fermentation treatment tanks 1, the stirring blades 3 rotate forward and reverse with the stop interposed therebetween to obtain a mixture of the organic waste, the water regulator and the fermenting bacteria. Thereafter, the operations of the stirring blades 3 and the heater 11 of the processing tank 1 are stopped, and the mixture is left in a state where carbon dioxide is in contact with the mixture A to form the mixture. Thereafter, the stirring blade 3 rotates forward and backward again with the stop again interposed therebetween, while the blower supplies oxygen from the air outlet 71 into the processing tank 1 and discharges it from the exhaust port 81, whereby the fermentation bacteria grow in the logarithmic growth phase. And fermentation and decomposition proceed actively. Thereafter, the mixture A is dried at a high temperature using a heater and a blower.

In the fermentation process in which the mixture has a high moisture content, the stirring blade 3 of the fermentation treatment tank 1 stirs the mixture at the bottom of the treatment tank 1, and at the same time, the horizontal blades 31 made of square wood, and the waste bone and the like. Agitation can be performed while grinding hard objects such as blades.
