When water is injected and air is supplied while stirring and natural proliferation is repeated for about 10 hours to 15 hours, the food waste is decomposed into liquid phase by the microorganisms and processed. However, according to the prior art 1, it takes a long time to process garbage, and it is inefficient to supply a large amount of water.

In Korean Patent No. 10-0216224 (hereinafter referred to as "Prior Art 2"), the food waste charged on the entire surface of the bottom of the fermentation tank is heated to rapidly discharge water, quickly regulate the temperature condition of the food waste, And a coil heater plate is attached to the heating plate so that the heating plate can be heated. However, according to the prior art document 2, only the structure for heating the food waste is described, and specifically, no description is given on how to maintain the activity temperature of the microorganism. Also, in the prior art 2, there is no mention of a structure for preventing food waste from adhering to the bottom and side walls of the stirring container.
