Patent ID: 11083168

Abstract:
A post-extrusion extruded granular sorbent processing system having a pellet-collecting enclosure that receives pellets of granular sorbent extruded from a starch-containing admixture through a die at a discharge end of an extruder and transports the pellets in air from an air mover flowing from the enclosure through a pellet-conveying duct of a pneumatic conveyor cooling and drying the pellets. The system includes a subsystem configured for processing the pellets after extruding, cooling, and drying using a pellet processing machine configured for reducing a size of each pellet having a size greater than a size reduction setting of the machine. A preferred pellet processing machine has rotating horizontally and circumferentially corrugated rollers with a selectively variable gap between the rollers providing the size reducing setting and configuring the rotating rollers for reducing a size of the pellets passing between the rollers having a size greater than the gap between the rollers.
