Abrégé
(EN)
588344 A separation disc 3 for a milk separator comprising a rotor 1, which separation disc together with other separation discs 3 forms a stack of separation discs 3 which are rotatable together with the rotor 1 about an axis of rotation x. The separation disc 3 comprises a truncated substantially conical portion 3a and an annular flange element 3b which is connected to the conical portion 3a at the latter’s smallest radius and extends therefrom radially inwards substantially perpendicular to the axis of rotation x, which flange element 3b has a radial extent corresponding to at least 10% of the radial extent of the substantially conical portion 3a. The inner radial edge of the flange element 3b is provided with a number of recesses 3d distributed along the circumference of the edge and adapted to protrusions 4a on a column 4 which is connected to the rotor 1 and which extends coaxially through the stack of separation discs 3. The recesses 3d are so configured that the protrusions 4a fill substantially the whole of the recesses 3d and the radial extent of the recesses 3d corresponds to at least 20% of the radial extent of the flange element 3b, the column protrusions 4a being adapted to entraining the cream during operation of the milk separator.
