ABSTRACT:
A pneumatic system for removing granular material, such as wheat, from a nonpressurized vessel such as a barge. Gas from a blower system is supplied to a plenum chamber mounted on top of two concentric pipes which extend down into the vessel. The gas flows down the outer pipe and is discharged into the granular material, thereby entraining it. The air and entrained material mixture then flow up the inner concentric pipe and out of the vessel. A rotary valve mounted on a chamber at the bottom of the concentric pipes allows granular material to flow into the chamber, but isolates the high pressure in the chamber from surrounding granular material.
