Chapter 7 Roller Milling of Wheat - ScienceDirect

Jan 01, 2007  The four possible break roll dispositions: sharp-to-sharp (S-S), sharp-to-dull (S-D), dull-to-sharp (D-S) and dull-to-dull (D-D). Returning to Fig. 5 , it is immediately evident that the particle size distribution produced from First Break, the first roller milling operation that the wheat encounters, determines the balance of stream flows ...

Effect of Roll Fluting Disposition and Roll Gap on ...

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-to-sharp, or dull-to-dull. Wheat kernel breakage under different dispositions during milling was studied using high-speed video imaging.

The breakage equation for roller milling allows prediction of the output particle size distribution from the feed particle size distribution in terms of a breakage function. Breakage functions were determined for First Break milling of hard and soft wheats under four roll dispositions: Sharp-to-Sharp (S-S), Sharp-to-Dull (S-D), Dull-to-Sharp (D-S) and Dull-to-Dull (D-D).
