A centrifugal separator for separating a dairy product into at least a liquid light phase and a heavy phase. The centrifugal separator comprises a disc stack of frustoconical discs arranged inside the centrifuge bowl. The disc stack comprises a first set of discs and a second set of discs. The discs in the first set of discs are separated from each other by spot-formed spacing members and with a distance that is smaller than 0.3 mm, and the discs in the second set of discs are separated from each other with a distance that is larger than 0.3 mm.

A method for processing milk, including separating raw milk into cream and skim milk, determining protein contents in the skim milk and the cream, dividing the skim milk into a first skim milk portion and a second skim milk portion, filtering the second skim milk portion into a permeate and a protein rich retentate, determining protein content in the permeate, calculating which flow rates are required for the first skim milk portion, the cream remix portion and the permeate to obtain a predetermined protein content of a mixture of the first skim milk portion, the cream remix portion and the permeate, which together form a standardized milk product.

A centrifugal separator for separating at least one liquid phase from a liquid feed mixture includes a frame, a drive member and a rotating part. The drive member is configured to rotate the rotating part in relation to the frame around an axis of rotation, and the rotating part includes a centrifuge bowl enclosing a separation space. The centrifuge bowl includes an inlet for receiving the liquid feed mixture, and at least one liquid outlet for a separated liquid phase. The separation space includes a stack of separation discs arranged coaxially around the axis of rotation. The separation discs include distance members arranged so that interspaces are formed between adjacent separation discs in the disc stack. A plurality of said separation discs include a throttle member other than the distance members and arranged to cause a decrease in pressure to a liquid flowing through the disc stack in the interspaces. The plurality of separation discs are configured to allow for a radial flow of liquid in the direction from the outer periphery of the discs to the inner periphery of the discs throughout a major portion of the discs.
