Detailed explanation-1: -Two methods of milling can be used for wheat, stone grinding and roller milling. Stone grinding is the traditional method of grinding the wheat between two large, heavy circular stones, where the top stone revolves on the lower one. The stones are grooved to assist in the grinding process.
Detailed explanation-2: -Grain processing as exemplified by flour milling (Fig. 15.4) is essentially a physical process whereby the kernel is cleaned, adjusted to an appropriate moisture content and then mechanically reduced to the desired particle size to produce a flour and by-products (e.g. bran).
Detailed explanation-3: -The wheat is grounded by a machine that crushes it into pieces. It is then put through sifters from which the meal obtained is processed further with repeated grinding and sifting. Then, the meal becomes fine flour, wheat germ and wheat bran.
