Abstract
An auger may have a spiral blade that extends radially outwardly from a shaft and that has resiliently-deformable material at the radial outer edge that physically contacts the inner surface of the tube in which the auger is positioned. When the auger is not rotated, the physical contact of the resiliently-deformable material on the inner surface of the tube may prevent granular material from flowing through the opening in the tube.
