Abstract
L'invention est relative à un procédé de fabrication de pâte chimique par cuisson de matière cellulosique, dans lequel on amène la matière à un réservoir pour la préchauffer, après quoi on l'introduit dans un lessiveur pour cuisson, ce procédé étant caractérisé en ce que l'on introduit une partie de la vapeur de détente (vapeur de soufflage) dans la partie inférieure de la couche de matière contenue dans le réservoir, et en ce que l'on retire des gaz non condensés du réservoir.
