摘要： PROBLEM TO BE SOLVED: To heat-sterilize easily and surely by forming a container having, as its constituent elements, at least a pair of aluminum electrodes and an insulation member and forming a conductive ink layer, which comprises a resin composition containing conductive powder, onto at least part of a face where an aluminum electrode contacts contents. SOLUTION: In the case of application to a rolled-can type as an electro- heating food-container, a conductive ink layer containing Ti-Al intermetallic compound powder is formed on an aluminum plate, and such an aluminum plate is die-cut to obtain can lid materials 1. On the other hand, a cylindrical resin can body 2 is produced by injection molding, in the case of which a layer 3, comprising rubberlike elastic body, for rolling and sealing is placed in a flange part in advance. Then, a bottom part is formed at one end of the cylindrical resin can body 2 by rolling and molding the lid material 1 so that the conductive ink layer comes as a container's internal face, and the electro-heating food container is thus obtained. Then, after food is filled into the container, it is hermetically rolled and sealed with the other lid material 1 so that the conductive ink layer comes as a container's internal face.

摘要： PURPOSE: To uniformly heat food by arranging a first electrode plate and a second electrode plane on both sides of a communication plate. CONSTITUTION: A communication plate 9 having a long hole 10 is interposed between a first through hole 3 of a first electrode plate 1 and a second through hole 4 of a second electrode plate 2, between the first through hole 3 and an end frame 12, and between the second through hole 4 and the end frame 12. By making conductive food 14 flow in a path 19, the first electrode plate 1 and the second electrode plate 2 are made conductive, and when AC current is applied to at least two electrodes, current flows between the electrodes. The food 14 becomes a heating body, Joule heat inversely proportional to electric resistance and proportional to the square of voltage applied is generated, and the food 14 is quickly heated independent of heat conductivity.

摘要： PURPOSE:To prevent the electrolytic corrosion even by passing electric current and to improve the durability of the subject heating apparatus by contacting an electrically conductive food with a specific electrically conductive layer and heating the food by passing electric current through the food. CONSTITUTION:An electrode 1 having electrically conductive layer 4 is produced by laminating an electrically conductive material made of a non-ionizable substance (e.g. carbon) on the surface of an electrode substrate 3. An electrically conductive food 2 is inserted into an insulating cylinder 5 and sandwiched with the electrodes 1 inserted into the cylinder from both opened ends. An electric current is supplied from a power source 7 through a piston rod 6 and the food is heated and sterilized with Joule heat generated by the current passing through the food 2.
