Apparatus and method for dispersing or refining of organic material, such as cellulose fiber and organic waste

An apparatus for dispersing or refining organic material the apparatus comprising:

• a rotor shaft extending along a rotation axis;
• a rotor connected to the rotor shaft so that when the rotor shaft is rotated, the rotor is rotated around the rotation axis,
• a housing arranged around the rotor, the housing having an inlet for receiving the organic material and an outer wall;
• wherein the housing is further arranged with a stator disc, and the rotor is arranged with a rotor disc, the rotor disc and the stator disc having material engaging elements, and the rotor disc and the stator disc being arranged opposite each other so that a gap is defined between them, whereby when the apparatus is in use, organic material introduced through the inlet will be fed by the rotating rotor through the gap between the rotor disc and stator disc to a dilution zone and towards the outer wall of the housing,
• the housing further having:
• an outlet arranged in the outer wall, through which outlet dispersed organic material is fed for transportation out of the apparatus, a flow path for organic material being defined by the inlet, the gap, the dilution zone, and the outlet in succession, and
• at least one dilution inlet arranged in the flow path downstream of the gap, in the outer wall and through which at least one dilution inlet dilution liquid is fed into the dilution zone, wherein the at least one dilution inlet is directed into the apparatus so that an axis of the at least one dilution inlet at an outlet of the at least one dilution inlet is angled in a plane that is substantially perpendicular to the rotation axis, towards a radial of the rotation axis.
