CENTRIFUGAL SEPARATION 



As more milk flows into the bowl, the wall of milk extends 

 farther toward the center until the skim milk begins to discharge 

 from the skim milk outlet. As the inflow of milk continues the 

 wall of milk in the bowl increases in thickness until the cream 

 begins to escape through the cream outlet. Simultaneously the

discharge of the skim milk increases. When the discharge of 

 the skim milk and cream outlets equal the inflow of the milk, the 

 thickness of the wall of the milk in the bowl becomes constant. 

 The proportion of cream to skim milk in any given separator 

 is controlled directly and exclusively by the relative distances of 

 the two outlets from the center of the bowl, assuming that the 

 separator is operated under otherwise normal and uniform con- 

 ditions.
