Question # 1

How cream separator work

Ans 1: Cream separate is a high-speed spinner which acts on the principle of centrifuge machines. The bowl spins at very high speed causing the heavier contents of milk to move outward in the bowl pushing the lighter contents inward towards the spinning axis. Therefore, skimmed milk, which is denser than cream is collected at the outer wall of the bowl the lighter part (cream) is pushed towards the center from where it is collected through pipe
