Experimental validation of a combined electromagnetic and thermal model for a microwave drying of capillary porous materials inside a rectangular wave guide (effects of irradiation time, particle sizes and initial moisture content).
In this paper, the experimental validation of a combined electromagnetic and thermal model for a microwave drying of capillary porous materials inside a rectangular wave guide is presented. The effects of the irradiation time, particle sizes and the variation of initial moisture content on the microwave drying kinetics are clarified in detail, considering the interference between incident and reflected waves in the capillary porous materials. The established model has allowed us to determine the space-time evolution of electric field, temperature and moisture content within capillary porous materials during microwave drying process.
