CLAIMS

1 . A centrifugal separator (100) for separating milk (RM) into a cream phase (CR) and a skim milk phase (SM), the separator (100) comprising

a centrifuge bowl (101 ),

a disc stack (102) of conical discs (103) arranged inside the centrifuge bowl (101 ), the disc stack (102) comprises

a first set of discs (106),

a second set of discs (107),

the discs (103) in the disk stack (102) comprises distribution openings (1 17) such that the milk (RM) passes the first set of discs (106) before passing the second set of discs (107), characterized in that

the discs (103) in the first set of discs (106) are separated from each other by a first distance (108), and

the discs (103) in the second set of discs (107) are separated from each other by a second distance (109) which is smaller than the first distance (108).

2. A separator according to claim 1 , wherein the number of discs (103) in the second set of discs (107) is higher than the number of discs (103) in the first set of discs (106).

3. A separator according to claim 2, wherein a ratio between the number of discs (103) in the second set of discs (107) to the number of discs (103) in the first set of discs (106) is in the range of 2 to 6, or in the range of 3 to 5.

4. A separator according to claim 2 or 3, wherein the number of discs (103) in the first set of discs (106) is in the range of 20 to 50 discs.

5. A separator according to any of claims 1 - 4, wherein a ratio between the first distance (108) and the second distance (109) is in the range of 1 ,2 - 2,4, or in the range of 1 ,25 - 1 ,60.

6. A separator according to claim 5, wherein the ratio between the first distance (108) and the second distance (109) is 1 ,33.

7. A separator according to any of claims 1 - 6, wherein the discs (103) in the first set of discs (106) are separated by 0,75 to 0,85 mm.

8. A separator according to any of claims 1 - 6, wherein the discs (103) in the second set of discs (107) are separated by 0,55 to 0,65 mm.

9. A separator according to any of claims 1 - 8, wherein discs (103) in the first set of discs (106) have an open center portion (1 10) for receiving a centering element (1 1 1 ) arranged in the centrifuge bowl (101 ).

10. A separator according to claim 9, wherein the discs (103) in the second set of discs (107) have a reduced diameter center portion (1 12) coaxially aligned with the open center portion (1 10) of the discs (103) in the first set of discs (106).

1 1. A method (200) of separating cold milk using a separator (100) according to any of claims 1 - 10, comprising

providing (201 ) a flow of the milk through the first set of discs (106) in the disc stack (102) arranged in the separator (100), and thereafter

providing (202) the flow of the milk through the second set of discs (107), which is stacked on top of the first set of discs (106).

12. A method according to claim 1 1 , wherein the cold milk is milk which is not heated.

13. A method according to claim 12, wherein the temperature of the cold milk is below 305C, or below 205C.

14. A method according to claim 12, wherein the temperature of the cold milk is below 11-C, or below 145C.

15. A method according to claim 12, wherein the temperature of the cold milk is below 135C, or below 105C.
