Abstract
The present invention is a system and process for drying and extruding a cellulosic compound. The compound materials are provided to a mixer in a desired ratio. The compound materials are then mixed together. Thereafter, the compound materials can be stored in a non-controlled environment until needed. When it is time to extrude the compound materials, the compound materials are transferred to a dryer at a location remote from the mixer. The dryer has a surface area enabling the compound materials to be sufficiently spread out for drying. The compound materials are substantially uniformly dried to a desired level in the dryer. The compound materials are then transferred to an extruder to be formed into a final net shape.
