摘要：
A refining plate for refining lignocellulosic material including: a radially outer peripheral edge and a substrate surface; a refining zone having a plurality of substantially radially disposed bars and grooves between the bars, wherein the bars protrude upward from the substrate surface and the grooves each have a groove width, and a steam channel traversing the bars and grooves of the refining zone, wherein the steam channel has a radially outer end radially inward of the outer peripheral edge of the plate and the steam channel has a width substantially greater than the groove width.
