An extractor is described, in which, above the filter base arranged in the housing a supporting frame is arranged, which is pivotable about an axis essentially parallel to the filter base and which is equipped with a plurality of rotatable devices which act in various ways on the extraction mass, such as for example suction devices, stirring devices and spreading devices. The devices can each be brought from an idle position into a working position and returned to the idle position by pivoting the supporting frame, each being rotatable in its working position about an essentially perpendicular axis on the filter base.
