Abstract
In the process, a starch-containing suspension 1 is divided at admixture of washing liquid 5 in a centrifuge "A" into starch-containing concentrate 2, a first liquid phase 3 with primarily dissolved substances and a second liquid phase 4 with primarily undissolved substances. The first liquid phase 3 is especially suitable as washing liquid in counterflow washing processes as it contains no obstructive undissolved substances. Also, the disposal of this liquid phase is simpler. The second liquid phase 4 with the undissolved substances is generated in higher concentration compared to conventional processes so that the processing of this phase is less cumbersome.
