The optical sorter not only used for the better quality it provides, but also color sorting machine save energy as it uses electronics rather than heavy motors. The color sorter requires reduced wear and tear maintenance. The color sorter first adopted in the durum milling process for the effective removal of ergot and black seeds contaminants to produce high quality, safer and cleaner semolina. Today, application of color sorters becomes wider in wheat flour milling to produce high quality and safe flour. The color sorting should be considered as a better option for inclusion in any modern wheat cleaning plant.
