[0002] During the planting, harvesting, transportation and processing of soybeans, dirt, dust and other impurities often adhere to the surface of soybean particles. If these impurities are not effectively removed, it will have a serious impact on the subsequent production process and the quality of the final product. Especially in the process of processing soybeans into phospholipid oil, if the dirt continues to adhere to the surface of the soybeans, these impurities will enter the phospholipid oil, which will inevitably lead to substandard quality of downstream soybean products. Currently, common cleaning and impurity removal equipment usually soaks soybeans in water and washes them by flushing with water, but some dirt will still remain on the surface of the soybeans, and the cleaning effect needs to be further improved.
