The aim of the invention is to provide a method for the skimming of whey, resulting in better whey cream fat quality and allowing for automatic regulation of the concentration of whey cream. Raw whey is fed into a skimming separator and broken down into a skimmed whey phase and a whey cream phase. Whey cream is discharged through a discharge line and a part thereof corresponding to 0.5-2% of the volumetric flow of the raw whey that is fed into the skimming separator is returned to the feed line of the skimming separator by means of a recirculating device. A density transmitter can be arranged in the recirculating device so that density measurements can be carried out. The density values are transmitted to an evaluation device, enabling regulation of a control valve which is placed in the whey cream discharge line. The method and device for implementing the method are used in the processing of whey which is produced during the production of cheese after the cheese has been separated from the fat during the coagulation of the milk. |
