Question

How is cream separated from milk?

Answer 1

1. Separating cream from milk is easily accomplished using centrifugation.
2. The process of separating the suspended particles of a substance from a liquid in a mixture by churning it at high speed is called centrifugation.
3. In this process the milk is rotated at a high speed in a centrifuge.
4. As the cream is lighter, it floats on top of the heavier and skimmed milk.
5. When the centrifuge machine is switched on, the milk is rotated at a very high speed in its container.
6. As a result of this centrifugal force acting on the milk, it helps to separate the cream from the skimmed milk.
