Abstract In this study, banana slices were dried at different temperatures in a closed-loop heat pump drying system. As the temperature and the slice thickness increased, the drying time also increased. Midilli & Kucuk model was found to be the best model to explain the experimental data. The effective moisture diffusivity ranged from 1.12 × 10−10 to 1.64 × 10−10 m2/s. The dependence of moisture diffusivity on temperature was described by an Arrhenius-type equation and the activation energy was found to be -51.45 kJ/mol. The highest mean specific moisture extraction ratio (SMER) and coefficient of performance (COP) of HPD system were obtained as 0.212 kg/kWh and 3.059, respectively, at the highest drying air temperature.

香蕉片在热泵干燥系统中的性能分析与数学建模

摘要 在本研究中，香蕉片在闭环热泵干燥系统中在不同温度下干燥。随着温度和切片厚度的增加，干燥时间也增加。Midilli & Kucuk 模型被认为是解释实验数据的最佳模型。有效水分扩散率为 1.12 × 10−10 至 1.64 × 10−10 m2/s。水分扩散率对温度的依赖性由阿伦尼乌斯型方程描述，发现活化能为 -51.45 kJ/mol。在最高干燥空气温度下，HPD 系统的最高平均抽湿率 (SMER) 和性能系数 (COP) 分别为 0.212 kg/kWh 和 3.059。
