ABSTRACT:
An apparatus for extracting solid residues from an aqueous slurry. The slurry is applied to the upper surfaces of disks that rotate in a hollow cylindrical vessel so that an evaporation enclosure is defined by the vessel and at least in part by the upper surfaces of the disks. Oscillating slurry dispensing arms are oriented radially relative to the axis of a hollow shaft that supports the disks. Slurry flattening rollers press the slurry on to these disk upper surfaces and slurry scraping means remove the residue from the rotating disk upper surfaces. Finally, a condensation enclosure is provided for removing liquid condensate from the vapor produced in the evaporation disclosure, and means is provided for eliminating non-condensable gases periodically from a condensation enclosure.
