An automatic cream separator is a machine used to separate cream from milk. It is commonly used in the dairy industry to produce cream, butter, and other dairy products. The separator works by using centrifugal force to separate the cream from the milk. Milk is fed into the machine, and the rotating drum of the separator spins the milk at high speed. This automatic cream separator causes the heavier milk to be forced to the outside of the drum while the lighter cream is forced toward the center.
