PROBLEM TO BE SOLVED: To improve exhaust efficiency by connecting a hot air generator and a feeding port at the lower part of a drier through a hot air blow-in duct and a hot air feeding duct and providing a hot air discharge fan through a hot air discharge duct on the upper part of the drier. SOLUTION: The hot air generator 13 is mounted adjacently to the drier 10 and a hot air feeding port at the lower part of the drier 10 and the hot air generator 13 are connected by the hot air blow-in duct of the hot air generator 13 and the hot air feeding duct 14. In the drier 10, the discharge fan 12 of hot air to be rotated by a motor 11 is attached to the hot air discharge duct 10a provided on the upper part. Thus, the hot air fed from the hot air blow-in duct of the hot air generator 13 through the hot air feeding duct 14 to the lower part of the drier 10 is made to pass through a drying drum in the inside and discharged from the hot air discharge duct 10a at the upper part of the drier 10 through an insulator and the discharge fan 12. Thus, air flow is increased, the influence of outdoor air is reduced and the exhaust efficiency is improved.
