| description | Disclosed is a modified refiner system for the acetylation of wood chip and/or wood fibre. The invention comprises a process for the acetylation of wood chip in a refiner system including a feed hopper component, a non-steam digester component and a refiner (defibrator) component in which the chip is contacted with an acetylating fluid between the hopper and the digester components within a connecting multi-zone compression feed screw.
L'invention concerne un système de raffineur modifié destiné à l'acétylation de copeaux de bois et / ou de fibres de bois. L'invention comprend un processus d'acétylation de copeaux de bois dans un système de raffineur comprenant un composant de trémie d'alimentation, un composant de digesteur ne fonctionnant pas à la vapeur et un composant de raffineur (défibreur) dans lequel les copeaux sont mis en contact avec un fluide d'acétylation entre les composants de trémie et de digesteur à l'intérieur d'une vis d'alimentation de liaison à compression multizones. |
