Centrifugal separation is a crucial element for the industrial production of starch. The success depends on a combination of increased productivity, premium quality and the economical use of resources.

Starch is obtained predominantly from starch-rich plants such as corn, wheat, potatoes, rice, peas and tapioca. With its integrated process lines for starch extraction Westfalia Separator occupies the leading technological position in this important sector.

Starch production essentially breaks down into three distinct technical processes: classification, washing and concentration of the extracted starch. Westfalia Separator has the requisite technical expertise and the appropriate equipment for each of these processes. Just how diverse the possible uses of decanters and separators are is reflected in the following summary of the principle raw materials and processes:
