Mixer with alternating sized flow passages

摘要

A mixer includes an elongate shaft having a U-shaped slot at one end and a mixer blade seated within the U-shaped slot extending to either side of the shaft. The mixer blade includes top and bottom beams extending to either side of the shaft with alternating convex and concave rungs of uniform width extending between the top and bottom beams. The top beams bottom beams and pairs of adjacent rungs define flow passages that vary in width from the top beam to the bottom beam.
