Numerical Simulation of Temperature Profiles during Convective Drying of Potato

According to the physical changes of potato sample occurred in the process of convective drying,on the base of Fick's second law and Fourier's equation,mathematical model and geometric physical model were set up in the process of heat and mass transfer during convective drying.Transient temperature profiles and influencing factors of internal potato were calculated by utilising the finite element numerical simulation method.At last,comparison of experimental data against numerical simulation representative results designed in convective drying has shown a very good agreement,implying that the model can be used to predict transient temperature profiles in potato.
