In 2018 the store installed a 40tph Zanin rotary cleaner. This improves grain quality by removing fine and large impurities. The product is fed by way of gravity into a cylindrical rotary drum covered with interchangeable perforated screens.
The choice of screen depends on the size of the product, its humidity and the type of waste being separated. It is especially beneficial to malting barley with high levels of screenings, dramatically improving quality.
