<p>The present invention addresses the problem of continuously stabilizing the prevention of electrical leakage in electric field processing heat-processing devices, prevention of the occurrence of harmful substances, shortening of frying time, reduction of oil absorption rate into fried foods, increase of umami components, etc. A bottomed oil-permeable floating electrode is disposed between the kettle-shaped electrode and the container electrode of an electric field processing heat-processing device in which: a bottomed oil-permeable container electrode for holding an object to be processed is disposed inside a bottomed oil-impermeable kettle-shaped electrode for holding oil; the kettle-shaped electrode is grounded; and a high alternating voltage is applied on the container electrode to process and heat, by the application of a high alternating voltage electric field, the object to be processed that is being held in the oil. The floating electrode is isolated from the kettle-shaped electrode and the container electrode, and the floating electrode is not electrically connected. The upper end of the container electrode is insulated by mounting an insulating member or applying an insulating coating. Between the bottom of the floating electrode and the bottom of the kettle-shaped electrode, multiple sheath heaters are disposed.</p> |
