ABSTRACT:
In a dryer for drying extrudable materials, a worm is rotatably disposed in a tubular sleeve which is equipped at its front portion with a hopper to supply extrudable materials. The worm is supported at its both ends by bearings in the sleeve or outside the sleeve. A seal screw is formed around the rear portion of the worm, and an outlet for discharging the extrudable material is formed on the side surface of the sleeve near the end of the seal screw. The end of the seal screw is connected with a flushing ring which is protruded from the end of the worm.
