METHOD FOR COMPOSING SHAFT AND PADDLE ASSEMBLY FOR MIXER AND PROCESSOR, MIXER, AND PADDLE ASSEMBLY

摘要

PURPOSE: To provide a method and means wherein a shaft and paddle assembly can produce larger power and can remarkably increase production ratio at a smaller stress level than the existing machine. CONSTITUTION: A method of constructing a shaft and paddle assembly for mixers and processors wherein radially aligned paddles 22 and 23 on parallel shafts 12 and 13 revolving at the same speed in the same direction of rotation, and both completely wipe and co-wipe the interior of the barrel of the mixer or processor which has a mixer chamber 11 comprising interconnecting cylindrical bores, is provided. The co-wiping paddles are formed with paddle bores of a configulation comprising alternating lobular projections 38 and root recesses 39 and arcuate corner portions on these projections and 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.
