For starch recovery clarifying decanters are installed in different process stages depending on the raw material.
For starch recovery clarifying decanters are installed in different process stages depending on the raw material.
For potatoes and tapioca they are used for fruit water separation and pulp dewatering, in the corn starch process GEA decanters are used for fine fiber and gluten dewatering. For the potato and tapioca starch processes it is important to remove the fruit water and with it the proteins and gums as soon as possible from the starch recovering process.
Decanters, with their high centrifugal force, offer the best performance in separating the fruit water and gums or proteins. In the corn starch process the dewatering of fibers and gluten helps to reduce the energy costs in the drying stage.
