ABSTRACT:
A continuous mixing process is discloses that provides improved dispersive mixing over conventional mixing processes Viscoelastic material is introduced and withdrawn at a constant rate into and out of a housing having a central shaft whereby the shaft has at least one plate extending perpendicularly from the shaft. A drive means is actuated to reciprocate the plate along the axis of the shaft in order to provide a squeezing of material between the plate and the end walls of the housing, or between the plate and annular partitions disposed within the housing. The process employs a squeeze flow motion around the parallel surfaces at a Hencky strain greater than 2 and at a rate corresponding to a Deborah Number greater than 10.
