 The figure makes clear the fact that if cream with a high 

 percentage of fat has been separated, no more fat has

been obtained from a given amount of whole milk than 

 if the cream has a low fat-content, for the weight of the 

 cream is less. 



If a well-made centrifugal separator is operated properly, 

 it will separate cream containing as high as 45 to 50 per 

 cent of fat, and there will be only the normal loss of fat 

 in the skimmed-milk. Usually it is not desirable that 

 cream should contain more than 40 to 45 per cent, for 

 very rich cream is wasted by adhering to cans, dippers, 

 and other utensils, and it is difficult to obtain a representa- 

 tive sample of it for testing.
