The principle of impurity removal in flour processing
In the flour processing process, the different impurities are removed from wheat gradually by different devices according to the characteristics of impurities.
Particle sizes: Screening equipment can remove larger and smaller impurities in raw materials.
Different suspension speed or density: The air separation equipment can remove light impurities in the raw materials.
Magnetic characteristic: Magnetic equipment can effectively remove magnetic metal impurities in raw materials.
Different strength: by wheat scourer equipment, the impurities with lower strength than wheat are broken and then removed by screening.
