ABSTRACT:
A method and an apparatus for thawing a frozen food by high frequency heating. The thawing process is divided into at least four stages of execution. A high frequency wave output is predetermined for each stage, and the execution time of each stage is automatically computed by a function stored in a microcomputer with the weight of the food stuff as a parameter. The use of a plurality of stages provides a faster and satisfactory method of thawing the frozen food stuff.
