Based on the mass and energy conservation equationa ofdrying kiln,the discrete drying mechanism model was established according to the finite difference method.The simulation model was compiled by MATLAB,and the steady state and dynamic process of discrete mesh model were simulated respectively. The simulation results show the steady state and dynamic process changes of the drying process intuitively,verify the correctness and rationality of the mechanism model,providing help for understanding the process characteristics of the drying system anda reference for the design of control algorithm and the realization of optimal control.
