A pre-cleaner machine is an essential component in agricultural and food processing operations. It is designed to efficiently remove larger impurities and foreign materials from grains, seeds, and other bulk agricultural products before further processing or storage. This machine typically uses a combination of screens, sieves, and air currents to separate items like sticks, stones, leaves, and other debris from the main product. By eliminating these contaminants in the early stages of processing, pre-cleaner machines help improve the overall quality of the agricultural product, prevent damage to downstream machinery, and enhance the efficiency of the entire processing line, ensuring a cleaner and safer final product.
