Abstract
A process for making pellets from a viscous material includes the steps of extruding the viscous material from a first conduit into a pelletizing fluid in a first zone; and passing the extruded viscous material and pelletizing fluid into a second zone having an increase in the velocity of the pelletizing fluid and a step-wise reduction in the pressure relative to the first zone. Advantageously, this step change combination produces sufficient forces by the pelleting fluid on the viscous material sufficiently to form discrete pellets of a substantially uniform size distribution.
