Separation of Cream and Skim milk is like all genius systems, amazingly simple.

The author has been working with a system where fresh milk is filled into a vat, not deep, but with a large surface. When milk was left nice and cold  overnight we could skim the necessary cream off in the morning with a special sweeper, like the one to the right

Mejeriet think the Dairy Industry around the World should send a lot of friendly thoughts to the Swedish Engineer Gustav de Laval who developed the continuously cream separator and thereby starter the development of Dairy development in many small Villages in the Countryside. The Danish Butter — Lurpak — Is a spin-of from this development

The Centrifuge or Separator is used in almost any industry where liquid need to be separated from something else e.g. oil from water, or getting rid of impurities

In the Dairy business, we also make use of a special Centrifuge, called Bactofuge to get rid of microorganisms in the milkge spoon in the morning.
