The traditional drying models fitted to experimental data and the drying coefficients were determined by means of nonlinear least square based on the Matlab software using the Gauss-Newton algorithm. The experimental data from infrared radiation drying of apple slices were used as measured samples. The tests were performed with the materials temperature of 60℃, the radiation power of 750W, the radiation distances of 100mm and materials thickness of 5mm. 15 different mathematical drying models were compared by some evaluation targets such as coefficient of determination (R2), square sum of error (SSE) and root mean square error (RMSE). It showed that the Modified Page equationⅡ model could sufficiently predict and control the infrared radiation drying process of apple slices.
