Beschreibung
Zusammenfassung:	An auger feeder includes a hopper having an inner hopper wall and an outer hopper wall where the inner hopper wall includes an air permeable surface. A space is positioned between the inner and outer hopper walls. A heater is coupled to an outside edge of the inner hopper wall or a n outside edge of the outer hopper wall while a feed screw is positioned along an inside edge of the inner hopper wall. The auger feeder additionally includes an evacuator coupled to a vacuum port that is positioned in the outer hopper wall. The auger feeder also includes an aperture exit positioned at a bottom of the inner and outer hopper walls.
