Summary:PURPOSE:To smoothly send a material to be treated to the discharge side of a drum while keeping the material to not stick to a screw, by allowing a scraper having a specific structure to rotate to the same direction by synchronizing with the screw. CONSTITUTION:A material to be treated which exists between the blades 5a of a screw 5 is inhibited from being rotated together with the screw 5 by means of a scraping body 6b because the scraping body 6b of a scraper 6 is inserted between the blades 5a of the screw 5. Further the scraping body 6b of the scraper 6 is made spiral at the same lead angle as the blades 5a of the screw 5, and also rotated synchronously with the screw 5 and therefore can be inserted between the blades 5a without interfering with the blades 5a. Further since the scraper 6 and screw 5 are rotated to the same direction, both are mutually turned to the directions passing by each other in the crossing parts of the scraping body 6b and the blades 5a, and scraping effect of the material to be treated is made large with the scraping body 6b.
