Complete Treatment of Food Waste using Vertical Carbonizer

Abstract

Conventional food processor was used as compost or feed after solid-liquid separation by crushing and compression. However, feedstuffs became difficult due to the inability to prevent toxic substances, and composting was reluctant to use inappropriately and excessively salty. Therefore, using food waste as its own heat source in the drying process will reduce fuel costs and provide new food treatment methods. The food waste that is rich in fat and protein is distilled and dried, the solid material is used as livestock feed, and the condensate is completely recycled as an external carbon source of deodorant or sewage treatment plant. At this time, the excess solid component is pyrolyzed in a vertical type carburetor, and a combustible gas is produced and burned to be utilized as a heat source of the food drying apparatus. The pyrolysis temperature of the dried food waste for making flammable gas was maintained at 400 ° C and in this case, the harmful gas was below the environmental standard. By maintaining 1200 ° C during combustion, the risk of dioxin was eliminated. The vertical carbonization system can be used as a solid fuel additive, a black gray concrete additive, a soil additive and the like, while the hydrocarbon gas produced by pyrolyzing the solid structure effectively is used as a clean fuel to reduce the fuel cost. Condensate is used as an external carbon source for liquid fertilizers, deodorizers and sewage treatment. This device is not necessary when using incinerator waste heat. In a food waste disposal facility in an area without an incinerator, the fuel can be self-sufficient and effectively reduce fuel costs.
