ABSTRACT:
A side unloading bin for storing and discharging free-flowing granular material, such as sugar, is supported on a floor capable of supporting the weight of the material in the bin and has side walls with a discharge opening near the bottom. A flexible, inflatable, generally cup-shaped, double-walled bag, having a slanted top supports the material on the floor, has its slanted top attached to the side walls, and is inflated to assist the discharge of the material through the discharge opening, particularly the material that will not discharge by gravity due to the angle of repose of the material. The discharge opening has a discharge gate and an openable hatch, to discharge to a conveyor. Controls operate from a material sensor near the discharge control and actuate inflation and deflation of the bag to ensure a continuous discharge of material.
