A comparison between different mathematical models for prediction of the drying behavior of some agricultural products

In this paper we have compared the different mathematical methods for prediction of drying behavior of potato, apple and banana in a convection tray dryer. Experiments have been conducted in different conditions and their results have been compared with model predictions. This study showed thatconsideration or ignoring of certain facts such as shrinkage may affect the model predictions. The energy efficiency, diffusion coefficients and shrinkage were also obtained and discussed in different experimental conditions
