Abstract
The debranning type flour milling which is considered as a new technology for replacing the conventional wheat grinding system features the removal of the outer layers of wheat grains containing high ash and the possibility to produce high quality flour efficiently. In this study, at first small grains such as immature and shrinkage grains were experimentally removed through the slots of the debranning screens during the debranning process and the small grains and large grains were separately ground. It has been confirmed that this method is effective on the improvements of debranning performance and flour milling efficiency. Furthermore, during the experiments on the commercial mill, the screens of 1.6 mm slot were used to remove small grains and the removed grains were returned to the third breaking process (3B). The results have made it clear that this method increased the flour extraction by 0.8% and improved the ash characteristics.
