277. In developing the separator the manufacturers have 

 tried to increase the capacity and still have efficient skimming, 

 also to overcome the interruption of the skimming caused by the 

 milk entering the bowl without interfering with the cream passing 

 to the center and the skim milk to the walls of the bowl. The 

 entering milk is now delivered in the bowl at a point 'between the 

 layer of cream and skim milk where the specific gravity is nearly 

 the same as that of the whole milk because the cream and skim

milk travel in opposite directions after entering the bowl, and the 

 continuous inflow should interfere as little as possible with these 

 currents. 



Advantages of Centrifugal Over Gravity Skimming 

 278. The same conditions that affect the cream rising by 

 gravity influence centrifugal cream separation, but to a less degree.
