Abstract
A refiner plate for the face of a refiner disc comprising a plurality of refiner segments arranged side-by-side on the face of the disc to form a substantially annular refining region. Each refiner segment has a plurality bars and grooves for refining a lignocellulosic material and forming a path for receiving and transmitting steam generated during the refining process. A plurality of dams are disposed within the grooves to retard the movement of the lignocellulosic material. A partial height portion of each dam adjacent the trailing face of the bar provides a flow path for the steam.
