Abstract
L'invention concerne la fabrication de pâte mécanique. Le procédé décrit est caractérisé en particulier par le fait que, tout en maintenant une surpression dans le défibreur, on retire en continu la suspension de pâte mécanique en la faisant passer par un hydrocyclone dans lequel elle se débarrasse de vapeur d'eau. Ce procédé permet de substantielles économies d'énergies.
