DENSIFYING BAG FILLING MACHINE

摘要

A bag filling machine capable of densifying particulate material in the bag being filled is herein disclosed. The bag filling machine comprises a shroud (20), spout (50), plug (32) and a bag filling tube (30) that is inserted in a bag (B) so as to seal the bottom end of the bag filling tube against the bottom of the bag. Particulate material is introduced into the bag filling tube (30), which is then sealed by the plug (32) and has a vacuum drawn therein to remove air from the particulate material. Air is then rapidly introduced into the sealed bag filling tube (30) from an air tube (36) to compact the particulate material. The bag filling tube (30) is then withdrawn from the bag leaving the compacted particulate material in the bag.
