ABSTRACT:
A stirrer for stirring dry goods is provided. This stirrer has a plurality of sides for stirring a mass of normally free-flowing, dry, particulate material in a container. The stirrer includes a rotatable shaft, two sets of end blades, and two spaced-apart sets of intermediate blades affixed to the shaft. Each set of end blades is proximate to a different end of the shaft and each end blade of each such set is inclined toward the other set of end blades. The two spaced-apart sets of intermediate blades are affixed on the shaft between the sets of end blades, one set of intermediate blades on each side of a mid point of the shaft. Each set of intermediate blades includes at least one pair of blades extending outwardly in opposite direction at an oblique angle from the same general location on the shaft. The length, angle and relative locations of the blades are selected such that the blades sweep paths of travel that define a volume substantially coextensive with the portion of the shaft between the two locations where the shaft is supported. The paths of travel of different sets of intermediate blades intersect to render or maintain the mass of particulate material free-flowing when the particulate material is being withdrawn from the container.
