Abstract

Uneven temperature distribution within the heated material is an important factor limiting the widespread use of microwave heating. This paper proposed a dynamic power regulation method to improve the uniformity of microwave heated materials. First, the microwave heating model was constructed by the finite element method (FEM), and the electromagnetic field model and temperature field model were solved to obtain the temperature distribution inside the heated material. Second, the effects of constant power heating methods and dynamic power heating were compared under the same conditions of total energy fed in. Finally, the simulation results showed that the dynamic power heating method was able to improve the uniformity in the horizontal and vertical sections by 69.1%-71.9% and 64.1%-71.8%, respectively, compared to the traditional constant power heating method. The energy conversion efficiency of the two heating methods was almost identical. These results showed that the dynamic power heating method can improve the uniformity of microwave heating and save energy.
