碩士 === 國立中興大學 === 農業機械工程學系 === 84 === This study is to find the optimal drying method of deep-bed peanut mechanical curing and analyze variations of moisture content using thin-layer model. The experimental results showed thata dual-temperature drying condition of 55℃-6hr-45℃, 0.7m3/ m3s air-flow rate and relative humidity lower than 2%RH to dehydrate the peanut moisture content reaching 10%(w.b.) is the best method in deep-bed peanut drying. From the result of germination test, the germination rate was not influenced by this curing process. In model prediction, the twin-compartment model is very convenient in 10cm thin-layer, but the Newton's law of cooling and the diffusion model could only fit on falling-rate period as the drying layer larger than 20cm.
