ABSTRACT:
A vertically standing, slender, cylindrical flow container with an upper intake connection for crushed raw sludge already heated to a pasteurization temperature and a lower outlet connection for pasteurized sludge. A slowly rotating guide member is incorporated into the container coaxially with the longitudinal axis of the latter and is driven by an electric motor via a reduction gear. The tube-like guide member core is provided with a plurality of continuous, helically-wound blades which extend from top to bottom and which, with respect to the direction of rotation of the guide member, form front and rear helical deflectors for the sludge. The helically wound blades also subdivide the circular cross-section of the passage of the container into a plurality of helically-wound individual channels. At the upper end of the container, the guide member is suspended in a combined radial/axial bearing outside the sludge area thereof, and in the lower part of the container, the guide member is guided in the sludge area by means of guide shoes fitted onto its blades. A stationary toothed overflow distributor is provided in the top of the container and is continuously charged with raw sludge by means of the intake connection. The guide member is driven by means of the guide member shaft end which projects from the container cover.
