Abstract
Kernel size uniformity is an important physical quality attribute in terms of processing efficiency, quality control, and milling yield. This study developed optimal grain sorting strategies for elevators to use to increase kernel size uniformity and determined the size of potential benefits from sorting. Cluster analysis and global optimization were used to sort grain loads to increase kernel size uniformity. Cluster analysis and global optimization increased the percent flour yield relative to no sorting by 0.13% and 0.32% respectively. Cluster analysis and global optimization increased the daily milling income relative to no sorting by 105 dollars (5%) and 266 dollars (13%) respectively.
