摘要： 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.

摘要： Method for processing polymer biomaterial composites into pellets including extruding strands of such a composite at a temperature of less than 220°C through a die plate into an underwater pelletizer, cutting the composite strands into pellets, transporting them through a slurry line to a dryer, wherein said step of transporting said pellets includes injecting high velocity air into said water and pellet slurry to cause said water to aspirate from said pellets and said pellets to retain internal heat, to reduce moisture uptake by said pellets, and to expedite transport and drying of said pellets, the injection of high velocity air contacting the pellet water slurry to generate water vapor by aspiration and disperse the pellets throughout said slurry line effectively separating the pellets from the water in the slurry line, and propagating the pellets at an increased velocity to said dryer, and said drying step includes drying said composite pellets with latent heat in said pellets and without additional heating to a moisture level in said polymer biomaterial composite pellets of less than 1%.
