In Bischofswiesen in Bavaria, Kasper Stangassinger has a very flexible round bale drying system with a dehumidifier. The system was extended from the original 9 to 27 drying holes. For this purpose, an additional air duct was built and supplemented with a corresponding high-performance ventilator. Rapid drying is ensured by a high-performance dehumidifier that is infinitely variable up to 24 kW and thus continuously increases the temperature and lowers the relative humidity.
