Abstract

PURPOSE: To thaw a frozen material properly regardless of the difference in density, water content, and freezing temperature, by detecting the temperature of the material from the time when the temperature of a sensor changes from drop to rise.
CONSTITUTION: The material 2 is placed on the bottom of the thawing chamber 1, and the control unit 7 is put into operation to drive the highfrequency generator 4, which applies a radio frequency power across the plate electrode 3 and the wall surface 27 of the chamber 1. The material 2 is thawed by the power, and the temperature of the material 2 is detected by the sensor 5 via the bottom of the chamber 1. At the preset temperaure, the unit 7 stops driving of the generator 4 to complete the thawing. Detection of the temperature from the time when the temperature detected by the sensor 5 changes from drop to rise permits the thawing control to start the radiofrequency generation when the switch is turned on.
