Abstract

A process for preparing low moisture content polymer biomaterial composites and expandable polymer biomaterial composites by extrusion through a die plate (18) into a waterbox (16) and pelletizing with cutter blades (14). Polyolefins or condensation polymers are melt blended with a solid or semi-solid biomaterial component (155), such as polysaccharides, including cellulosics and starches, or proteinaceous materials, including polypeptides, and are extruded, pelletized underwater, and processed with accelerated drying to achieve moisture levels as low as one percent (1%) or less.

Description

[0001] This application is a divisional application of the patent application with the application number 200680031593.1, the international filing date is August 31, 2006, and the title is "method and apparatus for granulating biological material composites" technical field [0002] The present invention generally relates to methods and apparatus for producing pellets with significantly reduced moisture content using underwater pelletization followed by accelerated drying of polymer biomaterial composites and foamed polymer biomaterial composites. More specifically, the present invention relates to underwater pelletizing of polyolefins such as polyethylene and polypropylene, substituted polyolefins such as polyvinyl chloride and polystyrene, polyesters, polyamides, polyurethanes, polycarbonates, or copolymers of the foregoing materials, and methods and apparatus for utilizing subsequent accelerated drying of these expandable or otherwise non-expandable (or otherwise) pellets or...
