Abstract

L'invention concerne un dispositif destiné à un appareil de raffinage d'une matière lignocellulosique. La vapeur d'eau engendrée dans l'intervalle de raffinage du raffineur pendant le processus de raffinage, qui reflue en direction du conduit d'alimentation en matière de départ, est extraite de ce dernier par une sortie dans laquelle se trouve un tamis laissant passer la vapeur d'eau et qui est ajusté de façon à coopérer avec un ou plusieurs éléments destinés à enlever les particules de matière entraînées par la vapeur d'eau et retenues par le tamis. Application à la production de pâtes à partir d'une matière lignocellulosique.
