Abstract
The physical and mathematical model of heat and moisture transfer during the drying of materials in the field below water absorption, also taking into account the heating energy of the microwave field is developed. The numerical solution of the developed system of equations for the three cases of wood plate drying is conducted: convective energy of the microwave field and combined, combining the two previous methods. The results of the numerical calculations, which include the distribution of temperature, vapor pressure and moisture content in the cross section of the plate at different times, as well as changes in the average moisture content and temperature in the drying process, are presented. Calculation results and conclusions about the differences and characteristics of convective, microwave and combined heating and drying are analyzed.
