Preparation pan. Located below the APS System, the preparation pan starts the cleaning process using its exclusive shaking action to stratify the heavier grain to the bottom and the lighter chaff to the top. Using this method to transfer grain to the sieves eliminates the need for shoe augers that not only complicate the cleaning process by keeping the grain and chaff mixed together but can result in added damage to the crop caused by the augers. Once material travels to the end of the preparation pans, the material flows over the dual ventilated cascade step allowing the chaff to be blown out of the sieve area.
This decreases the work load on the sieves, allowing for increased cleaning capacity. In-cab visual returns monitoring. 16
