Abstract:
In a method for treating a liquid-containing organic waste material comprising the steps of: continuously feeding the material into an upper inlet (11) of a substantially vertical, cylindrical treatment chamber (2); adding treatment chemicals to the material through a chemical inlet (14) on the chamber; mixing the materials and chemicals; heating the mixture to evaporate the liquid and degas the material so as to render the material into a higher solids content; and removing from the chamber evaporated liquid and gases; and wherein the mixing step is carried out by a plurality of beaters (20) mounted on a tubular sleeve (19) which is axially slideable on an exterior of and rotatable about a tubular body (18), said beaters (20) extending essentially to adjacent an inner cylindrical periphery of the chamber, whereby the sleeve (19) is simultaneously rotated about and reciprocated in an axial direction on the tubular body (18).
