ABSTRACT:
Apparatus for compressing bulk material into a storage bag including a hopper, an auger tube having an inlet port and a discharge port, an auger rotatably mounted within the auger tube, and a storage bag support framework affixed to the auger tube at its discharge end. The auger extends through the discharge port and into the area defined by the storage bag support framework to permit lateral displacement of the bulk material from the auger into the storage bag support and then into the storage bag. The auger preferably extends through the discharge port a distance of at least one flight; the pitch of the flights being shorter than those within the auger tube. The auger is unsupported adjacent the discharge port except by a pilot shaft which engages the compressed material within the storage bag.
