A discontinuous centrifuge consists of a rotatable centrifuge drum incorporating a drive spindle, a casing and a base. A hub of the centrifuge drum comprises a plurality of arms for the indirect or direct connection of the casing of the centrifuge drum to the drive spindle of the centrifuge drum. A scraper serves for scraping a product off the inner wall of the casing of the rotatable centrifuge drum. The scraper comprises an element which is pivotal about an axis, which axis extends in parallel with the axis of rotation of the centrifuge drum. The element comprises a blade which extends over almost the entire height of the centrifuge drum and makes contact with the product after the pivotal movement. The scraper is not moveable vertically. The arms of the hub have upper surfaces which are located below the drum base. The scraper is mounted independently of the swinging suspension of the centrifuge drum.
