Abstract A two-dimensional analysis of heat and mass transfer during radio-frequency assisted convective drying of a rectangular apple slice is performed using an implicit finite difference method. Temperature and moisture distributions inside the object are predicted. Effects of level of power density and heat transfer coefficient on moisture and temperature profiles in the product are evaluated. It is shown that increasing the level of power denstiy and heat transfer coefficient increase the temperature and decrease the moisture in the product. The results obtained from the present model are compared with those available the literature and a considerably good agreement is found.
