<p><span style="font-family:Verdana,Geneva,sans-serif"> A new device for retaining heavy impurities in seed cotton raw material doubles the efficiency of separating small and large particles, eliminating the risk of damage to the components of cotton processing machines. The working part of the device is equipped with pockets and plates that remove heavy impurities outside. These plates automatically open and close, preventing air ingress. The device is controlled via artificial intelligence through a smartphone and computer, making the removal of contaminants more convenient. A spring plate installed on the working surface prevents damage to the cotton during processing. This device helps maintain cleanliness at cotton processing plants, improves the performance of fiber-separating machines, and protects drying equipment from fire hazards. Moreover, it prevents damage to cotton, fiber, and seeds.</span></p>
