  • Cylindrical paste extruded particle compositions
    Publication number: 20020038828
    Abstract: Compositions comprising substantially cylindrical paste extruded particles having a mathematical average length to diameter ratio of 1.0 to 4.0 are prepared by a process for breaking and separating dried particles. The process utilizes an apparatus comprising a cylindrical screen and a hub. Upon relative rotation of the screen and the hub, reject particles are flung radially outwardly and expelled through openings in the screen.
