Fermentation and Drying Apparatus for Organic Wastes {Fermenting and Drying Apparatus of Organic Waste}

The present invention relates to an organic waste fermentation drying apparatus, and more particularly, to discharge the mixture containing the organic waste contained in the fermentation drying to the outside, and re-introduced the discharged mixture into the fermentation drying. The present invention relates to an organic waste fermentation drying apparatus capable of fermenting and drying organic waste in large quantities.

As industrialization and urbanization become more advanced, the emission of industrial and organic wastes increases and environmental pollution becomes more serious. Therefore, there is a need for more efficient purification facilities. Organic wastes are mainly composed of food wastes and animal wastes, and in particular, food wastes are emitted in large concentrations in populated areas, and rapid collection and purification are required due to odors.

Existing organic waste purification treatment mainly depends on landfill or incineration method, but landfill method causes pollution of nearby river or groundwater due to leachate runoff from landfill, and incineration method is a carcinogen There is a problem that dioxin is released.

As an alternative to the above method, the recycling of methane, solid fuel or compost through the decomposition of organic waste by microorganisms is commercially available. The decomposition of organic waste by microorganisms is largely classified into anaerobic microorganisms and aerobic microorganisms.

Anaerobic microorganism is a method of decomposing organic waste using anaerobic microorganisms, there is an advantage that can be used as an energy source of methane generated during decomposition. However, since anaerobic microorganisms are activated under neutral pH conditions, a process of neutralizing acidic organic wastes is required, and there is a problem that a facility for stably collecting and storing explosive methane is required.

Aerobic microorganisms use aerobic microorganisms to decompose organic wastes and remove water to utilize the final product as compost or solid fuel. However, this method is cumbersome to add chaff or sawdust or the like to the organic waste together with the aerobic microorganism to make a mixture, and to continuously stir the mixture for supplying oxygen necessary for the aerobic microorganism.
