Abstract

L'invention concerne la fabrication de pâte de bois. Elle se caractérise en ce que le défibrage s'effectue dans une enveloppe fermée 2 avec des sas 7, 8 pour l'amenée du bois et une conduite fermée 10 pour l'évacuation de la pâte de bois, afin de pouvoir travailler en surpression et à des températures supérieures à 100 degrés C. L'invention s'applique à des défibreurs à presses et à des défibreurs continus.The invention relates to the manufacture of wood pulp. It is characterized in that the defibration is carried out in a closed envelope 2 with airlocks 7, 8 for the supply of wood and a closed pipe 10 for the evacuation of the wood pulp, in order to be able to work under overpressure and at temperatures above 100 degrees C. The invention is applicable to press defibrators and continuous defibrators.
