Dairy processing benefits from new processes and testing facilities

n 2010, SPX Corporation acquired Gerstenberg Schroder, a prominent Danish designer, manufacturer, installer and service provider of processing systems and components serving the global food industry


with particular emphasis on fats and oils including butter and spreads. Gerstenberg Schroder will greatly contribute


in SPX Flow Technology’s contract announced in May 2010 to custom design and install a fully automated, continuous margarine and butter processing system at the new Tine Jaeren plant in southwest Norway. In July 2010, SPX also completed its acquisition of Anhydro, a Soeborg, Denmark-based global supplier of liquid concentration equipment, powder processing solutions, and dewatering plants and equipment. New process solutions recently announced by the company include SPX APV GoldStream, ECA (electrochemically activated) Water, LeanCreme and the new modular FX Systems range of skid- mounted packaged process plants that offer very short times to production through short delivery and minimal site work since the units are delivered fully assembled and tested in a container. Ken Rodi, president, SPX Flow Technology


EMEA, says the new innovations will help customers to improve safety, profitability and process efficiency. “With payback times of less than one year, there has never been a better opportunity to enhance food and beverage business performance,” he added. Take SPX APV GoldStream for example.


During the start-up, shut-down and cleaning processes in dairy plants, large amounts of highly diluted milk are typically poured down the drain. SPX APV GoldStream separates the milk from the water using a hygienic self-contained ‘plug and produce’ reverse osmosis process (Fig. 1). In a 1 million litres/day dairy plant, it can


recover 3.5 million litres of milk value per year and produce nearly seven million litres of useful clean water at the same time. The water can be used for cleaning in place (CIP) or can be further processed by an optional additional stage to provide polished water for more demanding applications such as process water for cheese or boiler feed water. “Nearly US$1.5 million of recovered milk, a


significant environmental benefit from reduced water use and reduced effluent all from a quick and easy-to-install unit with a typical pay back period of under one year result in an excellent example
