Process of Converting Flour from Wheat in Roller Milling

The Process of converting flour from wheat in roller milling is to crush the grain between a series of fluted metal rollers using a reduction process; the fine flour particles are shifted out at each pass, returning to the next set of rollers. The rollers mills enable greater quantities of white flour to be made at high speed. Unless run at slow speed, the friction of roller milling can cause
