Abstract

L'invention concerne une plaque de raffineur pour la face d'un disque de raffineur, comprenant une pluralité de segments de raffineur (10) agencés côte à côte sur la face du disque en vue de former une zone de raffinage sensiblement annulaire. Chaque segment de raffineur comprend une pluralité de barres (40) et de rainures (34) pour le raffinage d'un matériau ligno-cellulosique et la formation d'un parcours pour la réception et la transmission de la vapeur générée au cours du processus de raffinage. Une pluralité de moyens formant barrage (46) est prévue à l'intérieur des rainures, en vue de ralentir le déplacement du matériau ligno-cellulosique. Une portion à hauteur partielle de chaque barrage, adjacente à la face arrière de la barre, forme un parcours d'écoulement pour la vapeur.
