<??>Said groove may comprise a central semi-circular inlet part (3) in fluid communication with a peripherial main part (4) concentric to the center (6) of said disk. Preferably, said main part is extended by a radially inwardly curved end part (5).
<??>In said main part and/or the end part of the groove there are separate outlet holes (7, 8) in communication with slits or channels on the other side of said disk for withdrawing of the separated fractions.
<??>Especially there is provided a disposable package of supoporting means, separation unit or disk, housing and a stationary transferring element, which is adapted to be mounted on any existing drive-shaft for rotation. </p> |
