A 3D mathematical food model of Coupled Hot-air and Microwave (CTMW) heating was developed to understand complex microwave interactions in food. The heating process at different position of potato using CTMW heating was investigated numerically and experimentally. Simulated spatial temperature profiles were compared with experimental ones, and predict spatial temperature profiles were in good agreement with experimental ones. In this study, the effect of the potato's position inside cavity was studied. The simulation results were analyzed and evaluated. The results showed the loss power values& density distribution at different position of potato varied greatly, which directly led to the potatoes in the uneven distribution of temperature field. The results are useful in understanding complex microwave heating, designing CTMW heating systems.
