Wheat starch processThe commercial separation of pure starch from wheat is achieved by a two phase process. In the first phase, the wheat kernel is ground or converted into wheat flour by a dry milling process.
The second phase then separates the ground wheat or the wheat flour into its separte components (starch, gluten, solubles, fibre) by a wet separation process. The process is operated as an enclosed system in which process water is recycled in a closed circuit. The addition of fresh water is linked to a few points in the process.
