This pre-cleaner is designed for fast removal of light and rough impurities in the cereal. It is essential for the quality of the cereal that a pre-cleaner is installed at the dryer inlet. It homogenizes the product, preventing clogging and reducing energy consumption. The version with aspiration reduces the emission of dust into the atmosphere.
The product enters by gravity into a cylindrical rotating drum with changeable perforated screens. The good product passes through pre-set holes, while the rough impurities come out at the end of drum. The choice of screen perforation size depends on the product, the moisture content and the type of reject to separate.
