Characteristics of thin layer microwave drying of apple were evaluated in a laboratory scale microwave dryer at 2450 MHz. The drying experiments were carried out at 200, 400 and 600 W. The experimental data were fitted to nine drying models. The models were compared using the coefficient of determination (R2), root mean square error (RMSE) and reduced chi-square (v2). The Midilli et al. model b…
