Abstract
Systems and methods for treating grain stored in a grain pile with ozone are effective for treating grain for toxins, insects, mold, and/or odor. A method according to embodiments of the invention involves monitoring at least one of temperature and odor at a plurality of aeration outlet locations spaced around the grain pile. When an abnormal temperature variance or odor is detected at one or more of the aeration outlet locations, a determination is made as to a problem location within the grain pile where a treatment of ozone should be applied, and a further determination is made as to how best to apply ozone to the problem location. Ozone is then applied to the problem location within the grain pile to minimize nascent problems in the grain pile. The ozone treatment may reduce molds and toxins.
