To investigate the heat transfer phenomena in a flat cylindrical model food by microwave heating, temperature distributions were calculated numerically by fundamental equations under certain assumption by a mathematical model considered the angle of microwave incidence. The temperature distributions changed with their radius and as the radius became larger the region of hot-spots moved from a center to surroundings of the cylinder. To check these calculated results, observation of the temperature distributions in the cylindrical modeling samples by a synthetic paste and measurement of the temperature by thermocouples were performed under the same operating conditions as those of the theoretical analysis. The calculated temperature distributions agreed closely with the measured and observed ones.
