ADVANTAGES OF CENTRIFUGAL SEPARATOR 



115 



Effect of Slime in Bowl of Separator on Richness of Cream. 

 Experiments conducted by Guthrie and Supplee 1 show that 

 deposits of slime in the bowl do not have any appreciable effect 

 on the richness of the cream so long as the slime does not clog 

 the passages. 

 Advantages of Centrifugal Separator over Gravity Creaming. 



The operation of the centrifugal separator has undisputed 

 advantages over the gravity systems of creaming. The chief of 

 these are: 



1. Greater skimming efficiency. 



2. Richer cream. 



3. Better quality of cream and skim milk 



4. More uniform richness of cream 



Greater Skimming Efficiency. The centrifugal separator is 

 the most efficient apparatus available for the separation of milk. 

 Below table shows the relative skimming efficiency as secured 

 experimentally. 2
