Flow guide for underwater pelletizer

An underwater pelletizer which comprises a die plate with extrusion orifices terminating in a die face, a driven rotary cutter blade hub supported in opposed relation to said die face, cutter blades mounted on said blade hub and moving in a plane generally parallel to and closely adjacent said die face to cut strands of material extruded through said orifices into pellets, a water box enclosing said die face, cutter blade hub and cutter blades, said water box including an inlet for water flow into the water box and an outlet for discharge of a slurry of water and pellets entrained in the water, and a stationary water flow guide positioned in said water box to guide water and pellet flow through said water box.
