Inside the Wheat Milling Process: How Flour is Produced
Learn about the wheat milling process in brief through grinding, sifting, breaking, purification, reduction, and repeated cycles, leading to the production of flour. Various equipment such as roller mills, sifters, purifiers, and the break system are utilized to separate bran, endosperm, and impurities, ultimately creating refined flour.

Wheat Milling How Flour is Made Brief Overview
Grind and sift, grind and sift, grind and sift, grind and sift Breaker (rollers) Purification (sift) Reduction (Sift) Repeat!
Break System (Grind) The following occurs in a roller mill: Wheat kernel during this process. opens the wheat kernel scrapes the endosperm from the bran keeps the bran in as large of pieces as possible, keeping small bran pieces and bran powder to a minimum. Wheat bran that has been separated from the endosperm.
Purification System (First Step in Sifting) The following occurs in a purifier: removes impurities removes smaller bran pieces reduces coarse chunks of endosperm to fine, equally sized particles (sizings) (referred to as semolina in this video, which is made from durum wheat) Wheat purifier that removes impurities.
Reduction System (Sift) The following occurs with a sifter: reduce purified large course particles (middlings) into flour with the least amount of bran and germ contamination Purified middlings Particles from this reduction system go back to the roller mill to start the grinding and sifting process over! Flour is made after the middlings have been being grinded and sifted repeatedly
