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 a plurality of steam pockets for receiving, storing and transmitting steam generated during the refining process. Each steam pocket is defined by a series of gaps in adjacent bars such that the steam pocket extends radially and laterally across the refiner segment and such that the surface of the steam pocket is at or below the height of the groove surface. At least one bar extends radially between each adjacent steam pocket in a segment, thereby forming a discontinuous path for the movement of steam.
