Abstract

Navel and Minneola orange slices at different thickness of 3, 6 and 9 mm were dried using a forced air solar dryer and have been examined nine drying models defining thin layer drying behavior of it using statistical analysis. Therefore, the drying models have been fitted to experimental data by means of the coefficients in these models. The results display that the regression analysis was performed using the experimental data to develop a thin layer drying model. The best fit of the thin layer drying of Navel and Minneola orange slices is obtained by two-term and Page equations were selected for the mathematical modeling based on the value of R², c² and RMSE. Both fitted models were validated against the experimental data.
