Upgrading Crude Starch to High-Quality Starch

The quality and value of the final starch product is largely determined by the washing of the crude starch. White high-quality potato starch can be obtained only if fiber fragments, lipids, proteins, dissolved substances are washed out efficiently. Process steps in this stage are a multi-stage washing process, fine fiber separation, and starch recovery from wash water.

Multi-stage washing process

The starch is washed by concentrating the diluted starch in suspension and diluting it again with clearer water. In this way, contaminants are removed.

By using a counter-current flow principle, the amount of fresh water used is small. After this multi-stage process, almost all contaminants are washed out. Hydrocyclones are used in the washing stage. Applications of the Hovex Hydro Cyclone unit are concentration, peeler starch recovery and refining and washing of suspensions
