  • Pneumatic polymer eductor conveyor dryer
    Patent number: 4455761
    Abstract: A water-wet polymer is extruded through a die plate. Free water formed by extruding action at the die plate is atomized and/or evaporated into an air stream. The die plate assembly discharges the rubber/moisture into a closely adjacent cone/funnel-receiver openly surrounding the die plate, and connecting to and discharging into a lesser diameter conveying tube. The die plate and surrounding funnel are enclosed by a chamber so that air, input tangentially into the enclosure, provides a swirling vortex air flow at the die plate assisting in severing and stripping rubber particles from the die plate.
