PROBLEM TO BE SOLVED: To provide a dryer which has an inclined rotary drum and capable of evenly and efficiently drying a material having a high moisture content and sticky. ;SOLUTION: The subject relates to a cylindrical rotary type dryer having a rotary drum 1 which rotates around a gently inclined center axis. This dryer has an agitator shaft 23 which is placed with a downward bias from the center axis P of the rotary drum and agitating blades 29 which are fixed respectively to the forward ends of a number of arms 28 extending radially from the agitator shaft 23 and take their positions close to the inside wall surface of the rotary drum at its bottom. Each of the agitating blades 29 is shorter than the rotary drum in length in the axial direction and the agitating blades are timed to come closer to the inside wall surface of the rotary drum differently between the agitating blades placed adjacently in the axial direction in the rotary drum. It is desirable that the agitator shaft 23 is provided under the central axis P of the rotary drum and with a bias on the downstream side in the direction of the rotation of the rotary drum and the agitator shaft 23 is rotated in the same direction as the rotation of the rotary drum 1 and at a greater rate than the speed of rotation of the rotary drum 1.;COPYRIGHT: (C)1998,JPO
