Cream Separator, How Works[edit]

Centrifugal force is used to separate the cream from the milk. The receptacle for the milk is arranged with a spindle passing through the casing, so that it can be revolved at the rate of from 1,000 to 1,500 revolutions per minute. The centrifugal force throws the heavier milk near the outer part of the receptacle, where it is drawn off through a pipe for the purpose. The lighter cream, remaining near the center, is drawn out through another pipe. There is also a supply pipe so that the original milk can be run in while the machine is in operation.
