Tests of Cream Separators. 



One of the most important points in the economy of butter manu- 

 facture is the efficiency witli which the cream is separated from the 

 milk. The introduction of the centrifugal separator marked a 

 great advance in this direction and the rapid development and 

 improvement of these machines, by the business competition of the 

 various manufacturers, renders the question of the most efficient 

 kind of separator an important one for the creamery operator or 

 private dairyman. 



During the session of our Shoit Dairy Course for 1894, a series 

 of tests of various styles and sizes of separators was made and 

 published in Bulletin 66 of this Station. Previous to this, and at 

 the same time, tests of separators were made at several other 

 Stations, notably in Vermont and Pennsylvania and to these 

 reference will be made later on. 



The edition of Bulletin 66 having been exhausted and inquiries 

 as to the matters contained therein still continuing, another series 

 of tests was made during the Short Dairy course of 1895. The 

 machines used were the same, with one or two exceptions, and were 

 as follows : 



The Butter Accumulator manufactured by the Swedish Cream 

 and Butter Separator Co., Bainbridge, N. Y. This machine was 

 run in our tests only as a separator. 



The DeLaval, Acme Alpha size, manufactured by the DeLaval 

 Separator Co., 74 Cortlandt St., New York, I^. Y. 



The DeLaval, Baby No. 3 size, manufactured by the DeLaval 

 Separator Co., 74 Cortlandt St., New York, N. Y. 



Reid's Improved Danish, manufactured by A. H. Reid, 30th and 

 Market Streets, Philadelphia, Pa. 



The United States, No. 3 size, manufactured by the United States 

 Butter Extractor Co., Newark, N. J. The Vermont Farm Machine 

 Co., Bellows Falls, Vt., sole agents.
