At our training facility in Chojnów, the works including purchasing the grain and its cleaning and drying has been completed. At the moment, we take care about the quality of maize stored in silos. Besides the standard ventilation system, which is ventilators, we also have electric fans on the roofs of silos and we use innovative cooling system for grain – so called “refrigerators” that cool the grain up to a temperature of 8-10 °C for several days. For grain’s humidity and temperature control grain research we use temperature probes system. We are sure that our corn will be safe and will keep all its attributes.
