Abstract:
A high-frequency heating apparatus comprising:a mounting table on which to mount an object to be heated; rotation drive means to rotate said mounting table; temperature detection means to cover almost an entire area of said mounting table as a detection area by rotating said mounting table; radiation variation means to form variations in a high-frequency radiation intensity in a heating chamber; and control means to stop the rotation of said mounting table when a lowest temperature object comes to where the radiation is strong and heat the object while monitoring a surface temperature of the object by said temperature detection means, wherein said control means restarts to rotate said mounting table when present temperature data obtained from an object on heating shows a predetermined temperature rise from the lowest temperature, the predetermined temperature rise is determined based on temperature differentials between highest temperature and lowest temperature obtained from said temperature detection means before said mounting table stops to rotate.
