    • Fibre pulp is manufactured in a refiner with opposed refining members (22,23,24) rotary relative to each other and enclosed in a pressure-proof refiner housing (20). Steam is separated from the fibre pulp in the refiner housing (20) at the counter-effect of centrifugal forces generated by radial wing members (40) on a rotary refining member (23,24). The steam is led off separately from the refiner housing (20) through a steam outlet (42), which communicates with a space (41) radially inside of the wing members (40). The fibre pulp is discharged separately through a discharge device (50,60,70,80,90) while in the refiner housing the desired pressure is maintained.
