  • Start-up procedure for underwater pelletizer
    Publication number: 20070170611
    Abstract: A method for starting up or stopping and restarting an underwater pelletizer is described. The method involves inducing partial freeze-off of the polymer melt in the holes of an internally insulated die plate to prevent polymer drool by passing full water flow across the face of the die plate. The method advantageously does not require using hot oil to heat the die plate or decreasing and/or increasing the heating provided to the die plate.
