中文摘要 | 本研究在動態方式量取落花生莢、仁與殼在乾燥與回水時之平衡含水率,試驗結果顯示仁與殼獨立時可在24小時內達到平衡,整粒的聯須五日方能至平衡點,所量得之結果,以修正之HENDERSON模式進行迴歸分析,相關係數在0.99,標準誤差在0.05,HENDERSON模式與試驗結果吻合。 滯後現象存在於落花生的吸濕與脫水平衡含水率曲線間,兩曲線之差一般在1%以內,滯後係數為吸濕曲線含水率與脫水曲線含水率之比值,滯後係數與平衡含水率具有良好的線性關係。滯後係數之廻歸公式可與脫水之平衡含水率模式共用以預測吸水之平衡含水率。 |
英文摘要 | This study was to develop the dynamic method to measure the EMC of peanut pod, kernel, and hull. Kernel and hull could reach the equilibrium within one day, if the air could pass over them directly. The pod needed 5 days to be a equilibrium. The modified Henderson equation was used to simulate the experimental results. Most of the correlation coefficients were above 0.99, and the standard errors were below 0.05. Therefore, the modified Henderson model was suitable to simulate the EMC of peanut. The hysteresis phenomenon did exist between the adsorption isotherm and desorption isotherm by inspecting the experimental data. The hysteresis value was defined as the difference between two curves. Most of the hysteresis values were less than 1%. There was a good linear relationship between the hysteresis values and desorption EMC. Using the hysteresis equation and EMC equation together can estimate the EMC of adsorption accurately. |
