Effect of Roll Fluting Disposition and Roll Gap on Breakage of
ABSTRACT. Breakage of wheat kernels during first-break roller milling depends on many factors, including the disposition of the fluted rolls: sharp-to-sharp, sharp-to-dull, dull Dull-to-dull gives slippage between the flutes and the kernel, and thus imparts less shear strain than sharp-to-sharp. The planes with principal strain are shown in Figure 2 .Forces experienced by kernels during sharp-to-sharp and dull-to

different roll dispositions were made as described previously (Fang and Campbell 2002). Figure 2 illustrates the process of a kernel being broken under a dull-to-sharp (D-S) disposition. The black arrows show the points of initial contact on each roll, while the white arrows on the fast roll are shown for reference.Predictions have been developed for both sharp-to-sharp and dull-to-dull roll dispositions, and show encouraging agreement with independent data.
