Abstract

PURPOSE: The time when food thawing will finish is automatically determined depending upon change in signals of temperature detecting by infrared rays after the temperature has reached a predetermined level, thus effecting uniform heating independently from the conditions of the food.
CONSTITUTION: After the detecting signals attains the predetermined level, it stops for a certain time T and cycles of heating to a predetermined level are repeated to lessen the temperature difference between the inner side and the surface, thus the difference ΔS between the signal that reduces within time T and the predetermined level becomes smaller with every cycle. When this ΔS becomes smaller than the threshold value ΔS that has been predetermined, the heating finishes. This way of controll can finish thawing in a shorter time when thin food is thawed, and in a longer time with thick food, resulting in uniform thawing.
