3. For commercial purposes. 

 4 To facilitate cream ripening. 

 5. To secure sweet skim milk. 



What are the different methods of cream separa- 

 tion? 



, f hand separators. 



1. Centrifugal j powerseparators 



C shallow-pan method. 



2. Gravity j deep-setting method. 



Lwater-dilution method. 



What are the advantages of centrifugal separation 

 over gravity separation? 



1. More rapid. 



2. More thorough. 



3. Better cream, that can be of any desired per- 

 centage of fat. 



4. Fresher skim milk. 



5. Fermentations can more easily be controlled. 



6. Centrifugal force removes insoluble dirt from 

 milk. 



7. Less danger of milk and cream absorbing bad 

 odors. 



8. Insures a more even quality of butter. 



9. Less labor involved. 



What are the advantages of the shallow-pan sys- 

 tem? 



1. Cheapness. 



2. Simplicity. 



What are its disadvantages? >
