A bulk bag unloader system eliminates the need of handling 25- to 50-pound paper bags and the waste associated with material remaining in the bag and bag removal.  An operator can position bulk bags filled with dry-bulk ingredients by using a fork truck and lifting carriage or by an electric hoist with motorized trolley mounted on the channel beam.

The dry-bulk ingredient can be weighed and transferred to the terminal location by pressure or vacuum convey system. For optimal efficiency, when unloading dusty products, the bulk bag frame can be integrated with a dust filter and exhaust fan.  The collected dust can be returned to the containment hopper or to a dust drum.
