| 摘 要： | 研究了荔枝果肉微波真空干燥特性,探讨不同微波功率、相对压力及装载量对荔枝果肉干燥速率的影响。结果表明:微波功率和装载量对荔枝果肉干燥速率的影响较大,而相对压力的影响不明显。干燥试验数据用于对12种可利用的干燥模型进行非线性回归拟合求解,并确定模型系数。结果发现Modified Henderson andPabis模型具有较高的决定系数R2、较低的残差平方和(SSE)及均方根误差(RMSE),该模型能较准确地表达和预测荔枝果肉微波真空干燥过程的水分变化规律。

| Abstract: | The microwave-vacuum drying characteristics of litchi pulp were studied and the effects of microwave power, relative pressure and loading capacity on drying rate of litchi pulp were investigated. The results showed that the drying rates of litchi pulp were markedly affected by microwave power and loading capacity, whereas, there was no obviously affected by relative pressure. The experimental drying data of litchi pulp were used to fit twelve available drying models, and coefficients of models were determined by non-linear regression analysis. It showed that Modified Henderson and Pabis model had higher correction coefficient R2, lower square sum of error (SSE) value and root mean square error (RMSE) value and could exactly describe and predict the moisture dynamics of litchi pulp during microwave-vacuum drying process. |
