▎ 摘　　要

NOVELTY - Manufacturing automatic dehydrator (500), involves preparing a titanium plate of an electrode part as a drum shell. The electrode part is coated with a wear-resistant material and a protective film. A spray-coating graphene is formed on the electrode part that is formed in a heat treatment furnace. A drum device (100) is formed by welding a nut to an outer peripheral surface of a drum. An electrode is fixed with a bolt. USE - The method is useful for manufacturing an automatic dehydrator. ADVANTAGE - The method enables manufacture of automatic dehydrator having excellent wear resistance, chemical resistance, heat resistance and electrical corrosion resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the automatic dehydrator. 100Drum device 500Automatic dehydrator
