Fonction

TO SEPARATE CREAM FROM MILK BY APPLICATION OF A CENTRIFUGE SYSTEM

Technique

The continuous centrifugal cream separator, developed in Europe and introduced to Canada in the 1880s, transformed dairying. Early centrifugal machines had to be stopped to remove the separated cream and skim milk, but in 1878 Gustav De Laval of Sweden developed a continuous flow cream separator featuring an airtight bowl containing the milk and that rotated at high speed. Centrifugal force moved the skim milk to the outside of the container, leaving the lighter cream inthe centre for removal while the machine was in operation. Although the centrifugal seperator was far more efficient that the old setting method, it still left 0.16 per cent butterfat in the skim milk. The addition of baffles to the original hollow bowl diverted and elongated the paths of the skim milk and cream through the bowl, reslting in better separation. Pertrie's Magnate cream separator features baffles. A well-adjusted baffle bowl separator would leave approximately .1% fat in the skim milk.
