A wheat flour milling machine works by using roller mills, rollers made of special alloys, plansifters for sifting, dampeners, bucket elevators and conveyors to process wheat into flour. Key components include roller mills, plansifters made of high-strength steel and wood, stainless steel pipes and dampeners, with electronic parts and motors from Siemens. The machine can produce customized, fortified flour in a semi-automatic packaging process.
