1. A liquid separating drum (1) for use with a manure separator (3) in order to separate liquid material (11a) from solid material (11b) in a mixture material (11) of manure to be processed, the liquid separating drum (1) comprising:

  • an elongated main body (5) having a longitudinal axis (7), the main body (5) being removably mountable about a base frame (9) of the manure separator (3) so as to be rotatable with respect thereto, the main body (5) having an inlet (5a) for receiving the mixture material (11) of manure to be processed, and an outlet (5b) for releasing processed manure material, the main body (5) comprises a plurality of longitudinal slits (15) operatively connecting the interior (17) of the main body (5) to the exterior (19) thereof, the longitudinal slits (15) extending longitudinally with respect to the main body (5) and being provided circumferentially about said main body (5), each longitudinal slit (15) being profiled and defining an interface (21) configured for allowing liquid material (11a) to evacuate out from the interior (17) of the main body (5) via the interface (21) in a diverging manner through the slit (15), while retaining solid material (11b) inside the main body (5);

    a plurality of supporting ribs (23) disposed along the longitudinal axis (7) of the main body (5) and extending transversally with respect to said longitudinal axis (7); and

    a plurality of profiled bars (25) mounted circumferentially onto the supporting ribs (23) and extending longitudinally with respect to the main body (5) so as to define complementary profiled longitudinal slits (15), each slit (15) being configured for allowing liquid material (11a) of the manure to be processed to evacuate out from the main body (5) through said slit (15), while retaining solid material (11b) of the manure to be processed inside the main body (5), each profiled bar (25) comprising a central axis (27), and each profiled bar (25) being mounted onto supporting ribs (23) so that its central axis (27) is disposed at a given angle (Ω

    ) ranging with respect to a corresponding radial axis (29) of the liquid separating drum (1), the given angle (Ω

    ) ranging between about 2 degrees and about 4 degrees so as to provide the main body (5) with an inner peripheral contact surface (31) that is serrated, and the main body (5) of the drum (1) being configured for mounting at a positive inclination (β

    1) with respect to a longitudinal axis (9a) of the base frame (9), so that the outlet (5b) of the main body (5) be located higher than the inlet (5a) thereof.
