ABSTRACT OF THE DISCLOSURE The invention provides an improvement in a continuous sulphite or bisulphite cooking method for pulp, in which the pulp containing cooking liquor is removed from a digester to a subsequent defibrating step. The improvement relates to the pulp being cooled before defibrating to a certain temperature range and the pulp is defibrated substantially without washing of the pulp following discharge from the digester. The invention also provides an apparatus for carrying out the above.
