Effect of Different Positions on Hot-Air and Microwave Coupled Heating

Abstract:

This study aimed to investigate the effect of different positions on the hot-air and microwave coupled heating. Based on the mathematical model of hot-air and microwave coupled heating, distribution parameters of the end temperature field for seven spots were first obtained for whole potato heated in a particular cavity by numerical simulation techniques. The simulations were further by verified by the experimental results that different spots showed varied heat power values and density distribution after the conversion of microwave electromagnetic energy into heat power and uneven distribution of the temperature field. Therefore, great attention should be paid to the food spots in the hot-air and microwave coupled heating.
