Title:
乾燥装置及び光学フィルムの製造方法
Document Type and Number:
Japanese Patent JP5235469
Kind Code:
B2
Abstract:
According to one aspect of the present invention, a drying device which dries a coating film formed on a substrate with hot air, including an infrared radiator which heats the coating film at a temperature equal to or lower than the temperature of the hot air is provided. The hot air drying device includes the infrared radiator which heats the coating film. Accordingly, the temperature of the coating film in the initial drying stage can be quickly raised by the infrared radiator in comparison with a case in which the coating film is dried only with the hot air. Also, since the infrared radiator heats the coating film at a temperature equal to or lower than the hot air temperature, there is no risk of reducing the quality of the coating film by overheating the coating film. Accordingly, energy consumption can be reduced, and the drying speed can be increased. Any member may be used as the infrared radiator as long as the member can radiate infrared rays to heat the coating film at a low temperature equal to or lower than the hot air temperature. For example, a panel infrared heater may be employed.
