Bulk Bag Unloader

Bulk-Out Bulk Bag Weigh Batch Unloader moves weighed batches of contamination-sensitive materials.

Bulk-Out Bulk Bag Weigh Batch Unloader with manual dumping station and flexible screw conveyor automatically moves weighed batches of contamination-sensitive materials to downstream processes and allows rapid sanitizing.


BFC model discharger has a cantilevered I-beam with electric hoist and trolley for positioning bulk bags without the use of a forklift. A SPOUT-LOCK clamp ring atop a TELE-TUBE telescoping tube securely connects the clean side of the bag spout to the clean side of the equipment intake, and maintains constant downward tension on the bag as it empties and elongates, promoting complete discharge.


The flexible screw is the only moving part contacting material, and is driven above the point at which material exits the conveyor, preventing material contact with seals and allowing rapid sanitizing in place.

Additional features:

  • Flow-Flexer bag activators increasingly raise opposite bottom edges of bag as it lightens for complete discharge
  • Bag dump station with folding bag shelf allows manual dumping of minor additions into the hopper from hand-held packaging and containers.
  • Hopper is vented to a BAG-VAC dust collection system that draws airborne dust from manual dumping activities away from the operator when the hopper lid is open
  • FLEXI-FORCE lump breaker integral to the hopper reduces agglomerates and promotes the continuous flow of material into the charging adapter of the flexible screw conveyor
  • Load cells supporting the entire system are linked to a PLC that stops the flexible screw conveyor once the system has lost a pre-set amount of weight.
