An experimental study was performed to determine the drying characteristics of peeled longan under various microwave intensity by microwave vacuum dryer.Eight commonly used thin-layer drying models were adopted to fit the experimental data,non-linear regression analysis was also applied.The results indicated that the drying process of peeled longan involved three stages: acceleration phase,constant-rate phase and deceleration phase.The performance of different drying models was investigated by comparing the coefficient of determination(R2),chi-square(χ2) and root mean square error(RMSE).As a result,the Page model had higher accuracy in prediction than other models.The change of moisture contents during the drying procedure was well predicted by the model.
