[0002] Wheat flour, a powder made from ground wheat, is a primary food ingredient. During the growing, harvesting, storage, and transportation of wheat, various impurities, such as stones, dust, husks, insects, and their excrement, may be contaminated. These impurities not only affect the purity and taste of the flour but may also contain substances harmful to the human body and cause moisture, caking, mold, and deterioration. Therefore, wheat flour needs to be screened during production to ensure more uniform flour particles, facilitating subsequent processing.
