PROBLEM TO BE SOLVED: To prevent abnormal variation of voltage and current between electrodes, collapse of an AC waveform, difficulty of control, and damage of a transformer of a power supply caused by affection of leak current from an annular electrode for energization heating, when food materials are energized and heated by applying AC voltage across adjacent annular electrodes for energization heating, in a continuous energization heating apparatus in which electrodes for grounding are disposed on the respective outsides of electrodes on both side ends, among plural annular electrodes for energization heating forming a pipe line for energization heating.SOLUTION: Two electrodes for voltage application positioned on both end sides of a pipe line for energization heating are connected to an output terminal on the reference potential side of an output transformer of an AC power supply, among three or more annular electrodes for voltage application. |
