ABSTRACT:
A rotary mixing device provides an elongate powering shaft carrying at a first end portion mixing apparatus formed by a first outer annulus interconnected by quadrantally arrayed first radial elements to the first end portion of the powering shaft, and a second inner annulus spacedly distant along the powering shaft from the first annulus and having quadrantally arrayed second radial elements interconnecting the second annulus and the powering shaft, with each of the second radial elements of the second annulus being coplanar with one of the first radial elements of the first annulus. Elongate peripheral elements extend in quadrantal array to interconnect the first and second annuli with end portions immediately radially outwardly from each coplanar pair of first and second radial elements. The elements of the mixing device and the powering shaft are formed of rigid rod-like material having a circular cross-section of substantial area such that the volume of the mixing device comprises from ten to twenty percent of the volume defined by a figure that would contain the mixing device in an immediately adjacent relationship.
