| Summary: | 碩士 === 國立屏東科技大學 === 機械工程技術研究所 === 86 === In order to reduce the production cost and to improve the automatic composting process, GFW software had been used in this research to design a supervisory control and data acquisition system for simulating the whole compost production process of the agricultural wastes-treating center.
For 27 days'' experiments on the organic manure, the results showed that the change of fermentation temperature of compost product was normal in which temperature decreased from inlet 70℃ of raw organic manure to outlet 43℃ of dark-brown sandy compost. Meanwhile, the moisture content, pH, germination, TC, TN, and C/N all reached the standard condition of fermentation.
On the other hand, since much of dust would be produced during the composting process, the control strategy for fans had been designed to regulate the air flow in order to eliminate the problem of air pollution.
