Abstract
La présente invention concerne un procédé et un appareil de lavage d'un mélange de pâte à fibres permettant d'en éliminer l'eau entraînant avec elle les cendres et autres impuretés particulaires. En l'occurrence, on introduit entre deux toiles métalliques la pâte à fibres à laver de façon à faire passer par les deux toiles métalliques l'eau et les cendres à éliminer de la pâte à fibres. On fait alors défiler les toiles métalliques et la pâte à fibres sur une surface incurvée de façon à retirer tout supplément d'eau sous l'effet de la pression des toiles métalliques et de la force centrifuge. L'appareil comporte deux toiles métalliques (1, 2) et un poste d'essorage entre les deux toiles métalliques (1, 2), l'eau et les impuretés étant éliminées dans le poste d'essorage au travers des deux toiles (1, 2).
