        음식물쓰레기의 퇴비화를 위한 모듈형 건조장치 성능평가

        원정식,이상문,라종덕,서규태,장춘만 한국폐기물자원순환학회 2015 한국폐기물자원순환학회지 Vol.32 No.2

        This paper describes the performance of the module-type drying apparatus for the composting of a food waste. The drying apparatus mainly consists of a screw-type food waste agitator, an air exhaust blower, a heat supply tube and a heat source. Two different discharging flow conditions of the drying apparatus, 4 and 5 m3/min, are introduced. Partly dried by-products after six hours drying operation in the drying apparatus is obtained while drying temperature keeps constant of 60oC. It is noted that the by-products needs to sufficient decay period for the composting. Deodorizing apparatus having a zigzag flow and a nozzle, which is connected to the drying apparatus, is also designed to enhance the removing performance of the odor. Throughout experimental measurements, time to the drying temperature of 60oC near the screw-type food waste agitator is shortened as discharging flow rate of the system decreases. The moisture content decreases to 50 percent after operation for 4 hours. Furthermore, the odor of the food waste is satisfied with the environment exhaust standard through the deodorizing apparatus.
