碩士 === 國立高雄第一科技大學 === 機械與自動化工程研究所 === 100 === The excrement treatment is a deficient process of livestock automation. In this study we newly design and fabricate a rapid composting equipment of organic fertilizer for poultry''s excrement treatment. The price of import compost equipment is very expensive, and the maintenance is also problematic. The proposed design improves the above-mentioned problems. This equipment can deal with excrement amount of 120,000 chickens and finish fermenting on the same day. It also solves the problems of flies, stench, pollution of water, piling up the area, and infectious disease of H5N1~Nx, etc. The closed type tank is to get rid of flies and stench. The ferment time is shortened from several teens’ days to 24 hours. This proposed system can cut off the pile area, too. A heating blower was designed to dry and agitating blades were adopted to ferment the compost temperature. This study aims at designing and constructing the system, including the tank and agitation mechanism, stirred blades, and heating blower. The optimum processing temperature, air supply rate, and excrement moisture content in the fermentation process conditions are explored. Sequence experiments were carried out to find the best conditions within 24 hours to convert high-quality organic fertilizer. In addition to the contribution of the mechanism design, we also have a considerable contribution to the farming environment, health, and farmers’ income. However, the power consumption is up to 100 kw-hr. We redesign our process to cut down power consumption to 80 kw-hr, Our further study is that the power source can be replaced by using renewable energy for environment concerns.
