PREDICTION OF BREAKAGE DURING ROLLER MILLING OF …

2013-7-15 · dull-to-dull (D-D) roll dispositions. During milling, the breakage of wheat kernels during first break roller milling depends on many factors, including the disposition of the fluted rolls. Dull-to-dull gives slippage between the flutes and the kernel, and thus imparts less shear strain than sharp-to-sharp (see Figures 2 and 3).
