Abstract
Methods and systems for treatment of grain in a storage container using ozone may be used for treating grain for toxins, insects, mold, and/or odor. Downdraft methods for applying high concentrations of ozone to grain in a storage container treat grain without generating ozone-related objectionable odors or with generation of only minimal ozone-related objectionable odors. A method for downdraft ozone treatment of grain with minimal generation of ozone-related objectionable odors involves providing a negative air pressure at a bottom of a volume of grain in a storage container. A high ozone concentration is generated in air above an upper surface of the volume of grain. The ozone is drawn down into the volume of grain using the negative air pressure for a treatment time sufficient to effectively treat the grain without causing significant ozone-related commercially-objectionable foreign odors in the grain.
