Abstract

生籾の低温乾燥では品質の劣化を促進する化学反応が抑制されるため, 高品質米の生産が可能であることが示唆されている. 本研究では生籾の充填層および多段式乾燥装置における乾燥解析モデルを構築し, 生籾の冷却乾燥過程における籾水分を予測した. その結果, 実験値と計算値はよく一致し, モデルの妥当性が実験的に検証された. また, 冷却乾燥では水分むらの少ない均一乾燥が達成されることが明らかになった.

It was known that low temperature drying could produce high quality dried products, because it could reduce the chemical reaction during drying period. Models were developed to predict the moisture content of rough rice in deep-bed and tray-bed dryer. The model was based on heat and mass transfer equations between moist air and rough rice, and it was including a shrinkage effect caused by drying. Regarding tray-bed dryer, the mixing law of moist air was used to simulate low temperature drying. A set of differential equations was solved by finite differential method. Inlet air conditions data were used as input. Predicted results were in good agreement with the experimental data.
