 What factors affect the cleaning of raw grain in flour mills

        During the flour production process, the raw grain may not be cleaned cleanly for the following reasons:
Source of raw grain: Some crops may be affected by pesticides during the planting process, and these pesticides will remain in the raw grain. Agricultural products may also be affected by impurities in the soil or pollutants in the atmosphere. These impure raw grains may not be easily removed completely during the cleaning process.
Raw grain storage and transportation process: If raw grain is not properly preserved and protected during storage and transportation, it may be affected by mildew, contamination, or insect damage. These problems may result in raw grain being stored for a longer period, making it difficult to clean thoroughly.
Cleaning equipment problems: The equipment and processes used to clean raw grains may also lead to incomplete cleaning. For example, improper screen aperture, insufficient vibration or wind power of the cleaning equipment, or wear and tear of the internal cleaning components of the equipment may result in the inability to completely remove impurities.
Incomplete cleaning process: In flour production, there may also be problems with the process of cleaning raw grains. For example, steps such as soaking, rinsing, winnowing, and magnetic separation during the cleaning process may not be fully performed, resulting in impurities not being completely removed.
To ensure the thoroughness of raw grain cleaning, flour production companies need to conduct strict quality inspections of raw grains and select high-quality raw grain suppliers. At the same time, it is necessary to optimize and improve the cleaning process, ensure the normal maintenance and operation of cleaning equipment, and train operators to improve the cleaning effect. In addition, strengthening cooperation with farmers, suppliers, warehousing and transportation is also key to ensuring the cleanup of raw grains.
