Cleaning and Conditioning: The grains are first cleaned to remove impurities like dirt and stones. Sometimes, the grains are conditioned by adding moisture to make them easier to mill.
Milling: The conditioned grains are fed through a series of steel rollers. These rollers are set at precise distances to crush and break down the grains into smaller particles. The process is usually done in multiple stages, with the rollers getting progressively finer to achieve the desired flour consistency.
Separation: After milling, the flour is separated from the bran and germ using sifters or air classifiers. This step ensures that the flour has the right texture and quality for various baking needs.
Blending and Packaging: The final flour may be blended with other types of flour or additives to achieve specific qualities before being packaged for distribution.
