HOW FLOUR IS MADE
The flour production process begins with wheat stored in large silos, each holding several hundred tonnes. Upon arrival, wheat is weighed and checked for moisture levels, as damp grains can spoil in storage. From the silo, the wheat moves to a screen room, where impurities are removed through a series of sieves, de-stoners, and magnets. Conditioning follows, during which moisture is adjusted to make the grain suitable for milling, and different types of wheat are blended to achieve the desired qualities in the final product.
Milling is a multi-stage process. First, the wheat passes through breaking rollers that peel it open without crushing the bran, followed by sifting to separate the bran from the endosperm. Air purifiers further segregate lighter bran from the heavier endosperm. Reducing rollers then finely grind the remaining endosperm into flour. After the milling, flour is packed for distribution, with quality control measures in place at each stage to ensure consistency. Extraction rates determine flour types, with wholemeal flour retaining all parts of the grain, while lower extraction rates yield finer white flour.
