Abstract
Gas is removed from a fibre suspension of high consistency by means of an apparatus having a rotor chamber and a rotor disposed for rotation in the rotor chamber. The rotor has blades adapted to fluidize the fibre suspension and to cause a centrally located core of gas surrounded by a cylindrical layer of fibre suspension to form. The rotor has a plate located in the portion of the rotor opposite to the inlet of the rotor chamber which has an opening or openings close to the rotor axis. The gas is removed from the rotor chamber through the openings in the plate to a gas discharge and the fibre suspension essentially free of gas is discharged through an outlet. The operation of the apparatus is controlled by maintaining the pressure difference between the inlet and the gas discharge at a predetermined level.
