<p>A method and a means for manufacturing cellulose pulp from lignocellulose fibre material wherein the fibre material is treated under steam pressure. The treatment is carried out in a mill or similar means under such conditions that substantially all the liquid present in the material and/or added thereto during the treatment is converted into gaseous form or steam. The gas or steam thus generated, plus any added gas, is used to convey the cellulose material at high velocity to at least one subsequent separating vessel wherein the fibres entrained with the gas or steam are given a trajectory of motion in the course of which the fibre material is sorted with respect to weight, surface area, or other distinguishing characteristics.</p> |
