SCIENCE AND PRACTICE OF DAIRYING. 



Antonine Prandtl in Munich, regarding the separation of cream from 

 milk by centrifugal force. In consequence of this, in 1873, experi- 

 ments were conducted with the Eimer centrifugal separator, and an 

 engineer, Mr. P. J. Winstrup, undertook the construction of a 

 milk-separator. He made experiments in 1878 with a separator 



constructed by himself 

 in the dairy of States- 

 Councillor Valentine 

 in Jeddesdal, and in 

 1878 brought out a 

 workable separator, 

 which, however, was 

 not largely adopted in 

 practice. In the mean- 

 time, several other en- 

 gineers, particularly 

 L. C. Nielsen, had been 

 occupying themselves 

 with the construction 

 of milk-separators. In 

 the year 1878, there 

 had been set up on a 

 farm near Copenhagen 

 a separator for regular 

 work, Kongen's Ny torf 

 separator No. 10, de- 

 vised by L. C. Nielsen, 

 and made in the manu- 

 factory of Peterson 

 Brothers in Magle- 

 kilde, near Roskilde. 

 In the course of a year 

 it was distinctly im- 

 proved, and in the year 1879 it was changed into the form which 

 it at present possesses, and quickly became known under the name 

 of Nielsen & Peterson's patent separator. In the year 1881, the 

 Engineering and Ship-building Co. of Burmeister & Wain bought 

 the patent of 1878, and since that time the separator has been 

 known as Burmeister & Wain's separator (fig. 39). It has been 

 extensively used, especially in Denmark itself. It is warranted, and
