(EN) Separation disc and separator
Abrégé
(EN)
The invention relates to a separationdisc (3) and a milk separator comprising a rotor (1), which separationdisc together with other separationdiscs (3) forms a stack of separationdiscs (3) which are rotatable together with the rotor (1) about an axis of rotation (x). The separationdisc (3) comprises a truncated substantially conical portion (3a) and an annular flange element (3b) which is connected to the conical portion (3a) at the latters 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 separationdiscs (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.
