A discharge screw 14 is disposed on the outlet fixing plate 9 through a gutter 13 that connects from the inside of the rotating drum 1 to the outside, and is driven by a belt 16 from a forward/reverse motor 15 provided on the base 2. Reference numeral 18 designates a rear plate of the rotary drum 1, and a circular hole 19 is provided concentrically with the rotary drum shaft, and an inlet fixing plate 20 is brought into contact with and sealed in the circular hole 19. 21 is the sludge input hopper;
Reference numeral 22 denotes a sludge charging screw, the tip of which opens into the rotating drum 1 through the inlet fixing plate 20. 23 is a well-known dehydration treatment agent input hopper; 24
is a dehydration treatment agent inputting screw that falls from the tip to the base of the sludge inputting screw 22, and is driven by belts 27 and 28 from motors 25 and 26 provided on the base 2.
29 is an opening/closing lid of the rotating drum 1. Stirring blades 30, 31 and screw blades 32 are fixed to the inner surface of the rotating drum 1.

Continuously inserted inside. Rotating drum 1 is motor 1
1, it is rotating at 5 to 10 rpm. The sludge in the rotating drum 1 is stirred and rotated by the stirring blades 30 and 31, and is gradually sent forward by the screw blade 32 and falls onto the gutter 13 one after another. The discharge screw 14 in the gutter 13 is discharged to the outside of the rotating drum 1 by a motor 15. Hot air and water vapor generated by the reaction between the sludge and the dehydration treatment agent in the rotating drum 1 are discharged into the duct 34 through the through hole 33 of the outlet fixing plate 9.
