Recovery Unit
Starch Recovery Unit
Striving to reduce costs for fresh water and for waste water disposal, the potato processing industry focuses on reduction of water consumption. By separating the starch from the potato cutting water and flume water, the life of the water can be extended, and the costs for waste water treatment reduced considerably. An additional advantage of starch recovery is that the recovered starch is a valuable commodity
Working Principle
Water from the process lines is fed to a rotating screen. Coarse parts and a major part of fibers are removed before the water enters into hydro cyclones. In the hydro cyclones the starch is separated from the water. The effluent is returned into the process. The concentrated starch is dewatered on a rotating vacuum filter and collected in big bags.
