Abstract
The present invention relates to a method and a device for admixing of large amounts of gas into a fibre suspension of middle consistency (8 - 25 per cent) by means of a rotor provided with agitation means and arranged in a stirrer housing, the method substantially comprising the following steps: a) said gas and fibre suspension is introduced into the stirrer, b) said gas is admixed into the fibre suspension being in a fluidised state, while at the same time, the flow is restricted in such a way that the pressure variations caused by the inlet flow of the fibre suspension and/or outlet flow are prevented to influence the mixing process, and c) the mixture thus obtained is removed from the stirrer. <IMAGE>
