Abstract
The present invention includes an apparatus and method for processing solid waste products. The apparatus comprises a rotatably mounted cylindrical vessel having a first end, a second end and an interior surface, at least one end terminating in a hatch that may be opened to allow access to the interior of the vessel and sealably closed to allow pressurization of the vessel; a steam inlet for injecting stem disposed at one or both ends; a plurality of substantially straight blades protruding from the interior surface of the vessel, and each the blade extending substantially the entire length of the vessel, so as to be capable of transporting waste material from the bottom of the vessel toward the top of the vessel, and releasing the waste material to fall to the bottom of the vessel. The apparatus also includes one or more actuators for moving the vessel between a position wherein the first end is higher than the second end and a position wherein the second end is higher than the first end.
