To celebrate National Dairy Month…
Located in the Smithsonian Libraries' Trade Literature Collection, the De Laval Cream Separators catalog from 1913 features over seventy pages of illustrations and articles. Published by the De Laval Separator Company, ten centrifugal-based cream separator models are showcased with schematics detailing their special features and construction. Their largest cream separator, the 'Improved No. 22,' separated 675 quarts per hour, while their smallest, the 'Improved No. 19,' separated 340 quarts per hour. Though intended to be powered by hand, De Laval Separator Company did offer specially adapted electric motors for their machines. In addition, various topics are covered concerning cream production and the implementation of De Laval Cream Separators.
In 1877, Carl Gustaf Patrik De Laval "evolved the first continuous separator, which discharged the cream and skim-milk separately while the milk was being fed into the machine, and its commercial manufactures was begun in 1878." De Laval's company, which has included the De Laval Separator Company, still exists today, focusing on dairy-related endeavors.—Mary Jinglewski, with assistance from Jim Roan
