초록
Coffee wastes are by-products after extracting liquid from ground coffee beans. The coffee wastes were classified as household wastes, but they can be used as bio-solid fuels. Coffee wastes have almost no elements of heavy metal, and low heating values are more than 10% higher than wood pellets which is expected to be used as renewable energy. The purpose of this study is to design and manufacture a 20-horsepower Pelletizer to make coffee wastes as pellet-type solid fuels, and to analyze the possibility of use them as renewable energy through experiment. As results, it is found that if the compression ratio of dice used in ordinary wood Pelletizer is increased by about 50%, it was able to make coffee waste pellets with high strength and excellent heating value without additives for pelletizing.
