A Study on Uniform Heating of Solid Foods and High Viscosity Foods by Microwave Heating

In this paper, an microwave oven for disinfectant one application has been modeled by FDTD-HTE Method and reserched uniform heating of solution model simulated solid food and high viscosity food. We suggest two technique for uniform heating. First one is that water film is arranged around the food for reducing local heating of edge heating. Second one is that food is heated by using both steam and microwave. As a result, 2mm water film lower temperature of high temperature part in the food efficiently, by using uniform heating technique using water film. And we confirmed that 33% of uneven heating is improved. Moreover, we confirmed that steam heated edge of food and microwave heated center of food, and food is gone to about 60 degrees centigrade through uniform technique using both Steam and microwave.
