By this pneumatic process of elevatinggrain, the dust is separated and dischargedthrough the blower and the grain is aeratedand 345. PNEUMATIC GRAIN ELE-VATOR. French. A high-speed blower re-ceives the grain from a hopper in a regulatedstream through a funnel with sufficient air tomake it semifluid, in which condition it passesthrough the blower and is forced to the desiredelevation. By this method grain is dried andaired, and by substituting a chute from a grainbin to the hopper aeration and transfer to otherbins is easily made. A cleaning process by the passage of thegrain through the blower, but the dust is de-posited in the bin with the grain. Does wellfor a transfer system only. 142 AIR-POWER MOTORS AND APPLIANCES. 346.
