Abstract (en)
[origin: US4775243A] A mixing and kneading apparatus with a kneading shaft bearingly supported in a cylindrical housing, a plurality of disk elements mounted perpendicularly and axially spaced apart on the kneading shaft. The disk elements carry scraper edges arranged essentially transversely to the plane of the disk elements and facing the housing wall at a slight distance. The housing wall, the kneading shaft, and the disk elements are optionally heatable or and coolable. In order to obtain an intensive intermixing and a uniform retention time of all of the product particle present in the toroidal reaction space, at least one mixer arm connected to the housing or the kneading shaft projects into the toroidal space to a distance at least in the vicinity of the axial and radial center of the toroidal cross section between two axially adjacent disk elements. The mixing arm applies a mixing and/or transport action onto the goods or products present between the inner wall of the housing and the kneading shaft.
