Abstract
The disclosure relates to a method of improving the efficiency of fat separation in the separation of a liquid food product with a certain fat content. The method includes the method step that the liquid food product is caused to pass through a first separator where the product is divided up into a lighter and a heavier phase. The first separator is regulated so that the lighter phase will have a fat content which is less than 15%. The method also includes the method step that the lighter phase is caused to pass through a second separator.

A method for improving the efficiency of fat separation in the separation of milk with a certain fat content, comprising:
- passing the milk through a first separator where the milk is divided into a lighter phase which is cream and a heavier phase which is skim milk, the lighter phase of cream possessing a higher fat content than the heavier phase of skim milk;
- the first separator being regulated so that the lighter phase of cream produced after passing the milk through the first separator has a fat content less than 15%;
- and
- passing the lighter phase of cream divided out of the milk by the first separator and having the fat content less than 15% through a second separator different from the first separator to separate the lighter phase into a new lighter phase and a new heavier phase, wherein the new heavier phase possesses a lesser fat content than the new lighter phase.
A method for improving the efficiency of fat separation in the separation of whey with a certain fat content, comprising:
- passing the whey through a first separator where the whey is divided into a lighter phase which is fat and a heavier phase which is fat-free whey, the lighter phase of fat possessing a higher fat content than the heavier phase of fat-free whey;
- the first separator being regulated so that the lighter phase of fat produced after passing the whey through the first separator has a fat content less than 15%;
- and
- passing the lighter phase of fat divided out of the whey by the first separator and having the fat content less than 15% through a second separator different from the first separator to separate the lighter phase into a new lighter phase and a new heavier phase, wherein the new heavier phase possesses a lesser fat content than the new lighter phase.
