Document Type and Number:
Japanese Patent JP6775186
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To shorten a treatment time, regarding a drying furnace used for dryness of a roughened aluminum foil using in an aluminum electrolytic capacitor.SOLUTION: A dry furnace comprises: a pretreatment mechanism having a structure configured to cause a far-infrared heater to heat and evaporate washing water adhering to an aluminum foil surface, and discharge to the outside steam generated by heating; and a body mechanism configured to heat an aluminum foil with an air heating system. The dry furnace is configured to dry an erosion part where after the surface of the aluminum foil is dried by the pretreatment mechanism, the aluminum foil is roughened by the body mechanism, to prevent temperature reduction of the aluminum foil due to evaporation heat of washing water, thereby shortening a drying time of the aluminum foil.SELECTED DRAWING: Figure 2
