Abstract
在此研究中，以六種乾燥模式比較其於高粱穗乾燥曲線之適用性。相關係數值和殘差分佈圖被用為選擇之標準。研究結果顯示非線性模式可適用於兩種乾燥方式和不同風速，乾燥厚度條件下之各乾燥曲線。乾燥過程所需之平衡含水率可由此模式求得。乾燥常數K值受到不同乾燥條件顯著性影響。N值則無顯著相關性。在發芽率的比較中，K與N值並無顯著影響。以傳統所用乾燥過程水份損失率的計算方式並不能正確地顯示有關因素對乾燥性能之影響。
In this study, six drying models are evaluated for the fitting agreement of the drying curves of ear sorghum. The quantitative value of R-square and the residual plots are employed as the criterions. The results indicate that only the nonlinear drying model can appropriately describe the drying curves with different drying factors, such as drying methods, air flow rates, and thickness of grains. The final moisture content not available in present ERH/EMC models can be obtained by the nonlinear drying model. The K value of drying constant is significantly affected by above factors, however, N vaiue is independent with these factors. Germination ratio for sorghum kernels with drying treatment has no relationship with drying constants. The traditional method to calculate the moisture loss ratio can not express adequately the effect of drying factors.
