An improved underwater pelletizer adapted to prevent extruded material from agglomerating in an pelletizing assembly, which pelletizer includes a cutting assembly having (1) a shroud fixedly mounted on the outer periphery of the cutting assembly thereby preventing pellets from being trapped between the die face and the cutting assembly; and (2) novel knives contoured to conform in their angular positions to the curvature of the shroud.

The invention relates a mixer assembly for mixing liquids in a tubular container including: (a.) an electrically conductive central shaft member, (1) having a top end portion and a bottom end portion; (2) where the central shaft member is oriented longitudinally along the length of the mixing blade assembly; and (3) wherein the central shaft member is threaded along at least a portion of its circumference; (b.) a plurality of shearing members fixedly attached to the central shaft member for shearing the liquids when the shaft member is rotated; (c.) a vortex breaker member positioned below the blade members and above the bottom end portion of the central shaft member; wherein the vortex breaker member comprises: (1) a concave-shaped disk having an aperture substantially at its center, (2) wherein the central shaft member is positioned through, and fixedly attached at, the aperture of the vortex breaker member; (3) wherein the concave-shaped side of the vortex breaker member is oriented toward the bottom end portion of the central shaft member; (4) wherein all points along the perimeter of the circumference of the vortex breaker member are substantially equidistance from the center of the central shaft member.
