The starch milk from the fine extractor is pumped into a two-stage separator for impurity removal from the protein. After passing to a second dewatering machine, the starch milk has the starch content up to 18–20 Baume´ . Then, the concentrated starch milk is pumped into dehydration horizontal centrifuges (DHC) to remove water before
drying. The DHC consists of filter cloth placed inside, rotating at about 1000 rpm to removewater from the starch milk.
