Abstract (en)
[origin: WO9742078A1] A portable unloader for bulk bags adapted for storing and handling ingredients of batch processes. The unloader has a rigid top frame (3) for supporting the bulk bag and bottom frame (2) connected by a hinge (4), with an inflatable membrane (5) disposed between the frames (2, 3). When the membrane (5) is inflated by a blower (25), the top frame (3) pivots and material flows to a hopper (7) having a metering valve (10).
