Canada

Mechanical separation allowed dairy farmers to increase their yield of butterfat-and income. Hand-cranked mechanical separators began appearing on Canadian farms in the 1890s and were commonly used by farm women and children as part of their labour routine. Canadian manufacturers, such as The National Manufacturing Co. and the Renfrew Machinery Co, produced mechanical separators for the domestic market. De Laval was a Swedish company with factories in North America, including Peterborough, Ontario.

Fonction

TO SEPARATE CREAM FROM MILK BY APPLICATION OF CENTRIFUGAL FORCE

Technique

In 1878, Swedish firm De Laval developed a continuous flow cream seperator with an airtight bowl that contained the milk and rotated at highspeed. Centrifugal force moved the lighter cream to the centre of the container and the skm milk to the outside for removal while the machine was in operation. Earlier centrifugal separators had to be stopped to remove the separated cream and milk. This innovation transformed the dairy farm. In the 1890s, De Laval introdcced a lasting refinement by using conicalmetal disks that increased the separator's efficiency. Continuous flow cream separators were often manually operated, and later, power driven. Rural electrification meant that separators, such as this one, could be outfitted with an electric motor. De Laval also made all-electrically operated separators.
