Process and device for mixing fluid into a pulp suspension of cellulose-containing fibre material, in which the pulp suspension is pumped in through a pump inlet, brought into rotation and, at the desired reaction pressure, mixed with the said fluid while passing through a reaction sector comprising a stator shell, a rotor which is coaxial therewith, and at least one fluid inlet, after which the pulp mixture leaves the reaction sector through a pulp outlet, in which the fluid, via the said fluid inlet, is supplied in the vicinity of the centre of rotating pulp suspension, where the local pressure in the pulp suspension is lower, due to the centrifugal force increasing radially outwards, than the reaction pressure prevailing at the periphery of the pulp suspension.

Procédé et dispositif servant à mélanger un fluide à une suspension de pâte composée de matières fibreuses à base de cellulose. On introduit par pompage la suspension de pâte dans l'orifice d'entrée (17) d'une pompe, on met en rotation la pâte et, une fois obtenue la pression réactionnelle voulue, on la mélange audit fluide dans une zone de réaction comportant une enveloppe de stator (1), un rotor (7) coaxial par rapport à l'enveloppe, et au moins un orifice d'entrée (23) pour le fluide. Ensuite, le mélange de pâte quitte la zone de réaction par un orifice de sortie (20) de la pompe, dans lequel le fluide, introduit par ledit orifice d'entrée (23), est amené au voisinage du centre de rotation de la suspension de pâte en rotation, où la pression locale dans la suspension de pâte est moins élevée que la pression de réaction régnant à la périphérie de la suspension de pâte, puisque la force centrifuge s'accroît dans le sens radial et vers l'extérieur.
