Abstract
The apparatus for treating viscous substances described is composed of a heatable vessel with, on one side, an inlet for the materials of the mix and, on the other side, an outlet for the materials of the mix and of two or more corotating shafts to which mixer elements have been attached, characterized in that the mixer elements are composed of two layers of bars, which are arranged crosswise in relation to each other, connected to one another. There are pins running axially attached to the face sides of the bars. These clean the interstices between the bars of the mixer elements of the adjacent shaft.
