Abstract
PURPOSE: To prevent the occurrence of partial boiling of a frozen food and to defrost it uniformly, by forming an anode plate smaller than the upper surface of frozen food in a device defrosting the frozen food placed between the anode and cathode plate through induction heating caused by high-frequency voltage.
CONSTITUTION: The shape of the anode plete 11 which is in contact with the top surface of the frozen food 13 to be defrosted is made into almost the similar figure of the top surface of frozen food 13 and a ratio of length a, from the center C of the line connecting the corners A and B of the frozen food 13 to the corner D of the plate 11 to length b from C to A is regulated to 40W80%. The high-frequency electric power generated by the high-frequency device 4 is applied through the anode plate 11 to the frozen food 13, wherein an induction heating phenomenon occurs to defrost the food. The high-frequency voltage causes a displacement current to flow. The displacement current flows much in the part within the displacement current line 15 and flows little around the periphery 16. Consequently, the temperature rises within the displacement current line 15 but it rises a little around the periphery 16. The part 14 of the corner of the surface, on which the electric power has beam apt to concentrate, does not cause boiling by overheating.
