Abstract

See full text

A method of constructing or reconstituting a shaft and paddle assembly for mixers and processors wherein radially aligned paddles on parallel shafts revolving at the same speed in the same direction of rotation both co-wipe and completely wipe the interior of the barrel of the mixer or processor which has a mixer chamber comprising interconnecting cylindrical bores. The co-wiping paddles are formed with paddle bores of a configuration comprising alternating lobular projections and root recesses, and arcuate corner portions on the lobular projections and root recesses. The arcuate corner portions of the projections are tangential to the arcuate corner portions of the root recesses. The shafts are formed with intermeshing matching projections and root recesses.
