<p>A drying apparatus (10) is composed of: a filament (32) emitting infrared rays by heating; an inner tube (36) which absorbs the infrared rays of a wavelength exceeding 3.5μm and covers the filament (32); and a heater (30) having an outer tube (40) configured to dry by emitting the infrared rays to a sheet-shaped film (82) which returns in a roll-to-roll mode. In addition, a part (the part within a furnace body (12)) on which the infrared ray is irradiated from an infrared ray heater among the film (82) is cooled. A cooling apparatus (60) supports the film (82) to enable to be returned by a belt conveyor (61). A water cooling roll (65) is formed with a second fluid path (65a) in order to allow a second refrigerant to pass an inner side rather than a ring of a belt (62).</p> |
