Furthermore, it is conveyed upward by the vertical screw conveyor 20 and returned to the upper center.

止され、有機廃棄物全体が良好に撹拌される。[0030] If the screw conveyor is driven only, an immobile layer of organic waste is likely to be formed in the area directly above the horizontal screw conveyor 16 near the vertical screw conveyor 20, and that area solidifies, causing an arch phenomenon. Although it is easy to do so, by rotating the rotary vane 25 for preventing arching phenomenon, solidification in that part is prevented, arching phenomenon is inhibited, and the entire organic waste is well stirred.

The organic waste is put into a fermentation tank equipped with an agitator, and the crushing agitator is activated to crush the biodegradable plastic while stirring the organic waste, and the biodegradable plastic bags and organic waste are fermented by microorganisms. As before,
Compared to placing organic waste such as food waste in plastic bags and disposing of it, the food waste can be placed into the fermenter without taking it out of the bag, and the biodegradable plastic bag remains in the fermenter. It is possible to hygienically ferment organic waste such as food waste without scattering foul odors or dirt around it, and without having to separately dispose of dirty garbage bags.
