Anew market opened in 1983, when Roger Fair and George Conrad developed an experimental continuous centrifugal for lactose production and tested it at the Dairy Products Company in Litchfield, Minnesota. Prior to that, cheese producers typically dumped unneeded whey on fields as fertilizer, but it was recognized that lactose sugar and pharmaceutical lactose sugar could be extracted from the whey. Strict dairy industry regulations demanded an entirely new design that could be cleaned in place without being disassembled. Dubbed the CP-30, the product survived an excruciating USDA review process before being approved for lactose production. In addition to producing centrifugals for the industry, Western States even constructed a complete lactose factory for the Valley Queen Cheese Company of Milbank, South Dakota. Leveraging New Technologies CHAPTER 9 left: The Quadra-Clean™ centrifugal by Western States was the first USDA approved clean-in-place (CIP) basket centrifuge. The first installation occurred in 1982 at Le Sueur Cheese Company, located in Le Sueur, Minnesota, to process milk sugar.
