PROBLEM TO BE SOLVED: To provide a business drier which has a high drying efficiency and is free from the biting of objects to be dried. SOLUTION: The cylinder 210 of an inner drum 200 is provided with many holes 211, a ring-like front side mirror plate 220 is provided with many holes 222, and a rear side mirror plate 230 is provided with many holes 232 in an area 233 of a shape different from a circular shape centering a shaft 231, a rectangular shape for instance. The objects to be dried are fed into the inner drum 200, and heated air is blown into the inner drum 200 through many holes 222 from the front part of the inner drum 200 and through many holes 232 from the rear part of the inner drum 200. Since the end part at the front of the cylinder 210 is turned to the shape of being folded back to the inner side, the objects to be dried are prevented from being bitten in the gap of an outer drum 150 and the inner drum 200 by the rotation of the inner drum 200. Also, since the area provided with many holes 232 is not circular centering the axis of the inner drum 200, the heated air is applied to the objects to be dried variously accompanying the rotation of the inner drum 200 and the drying efficiency is improved.
