HIGH-FREQUENCY HEATING UNIT

摘要

PROBLEM TO BE SOLVED: To heat the whole body of food uniformly at the unfreezing of frozen food by a high-frequency heating unit. SOLUTION: Food 1 stored in a heating compartment 3 is heated by high frequency while cooled by a cooling means 4. The surface and the inner part of the food 1 can be heated uniformly as the progress of the heating of the surface of the food 1 which is easy to be heated is delayed by the cooling and the inner part of the food 1 can be heated by the high frequency with the characteristic of the high frequency easily penetrating into the inner part of the food 1.
