Abstract:
1. A system, comprising: a selectively sealable container having a top portion, a bottom portion thereunder, a container gas connector, a pan separating the top and bottom portions, and a plurality of apertures through the pan through which gas flows from the bottom portion to the top portion; a discharge port sealably connected at a low portion of the pan; a bridging conveyor tube having a first end, a second end and a plurality of apertures spaced along a portion of the bridging conveyor tube between the first and second ends, the bridging conveyor tube being sealably connected at the first end to the discharge port; a bridging gas passage, adjoining the bridging conveyor tube, having a gas connector in fluid communication with the plurality of apertures spaced along the portion of the bridging conveyor tube to provide gas flow from the bridging gas passage to the bridging conveyor tube; a vertical riser conveyor tube having a wall with an outer diameter, a plurality of apertures in the wall, a first end connected to the second end of the bridging conveyor tube and a second end positioned adjacent to a receiving bin remote from and elevated relative to the container, the riser conveyor tube being sealably connected at the first end to the second end of the bridging conveyor tube; a riser gas passage, adjoining the riser conveyor tube, having a wall, an outer diameter that is smaller than the outer diameter of the riser conveyor tube, a gas connector and a plurality of apertures in the wall spaced along at least a portion of the riser gas passage, the plurality of apertures sealably engaging the plurality of apertures of the riser conveyor tube through which gas flows from the riser gas passage, through the engaged apertures in the walls of the riser conveyor tube and riser gas passage and into the riser conveyor tube; and a source of the pressurized gas sealably connected to provide pressurized gas to each of the gas connector of the container, the gas connector of the bridging gas passage and the gas connector of the riser gas passage.
