Systems and methods for ozone treatment of toxin in grain

A method for treating grain with ozone, the method comprising:

• separating grain based on density into a first, more dense batch having mycotoxins and a second, less dense batch having mycotoxins, where the first, more dense batch has less mycotoxins than the second, less dense batch;
• placing the second, less dense batch of the grain in a storage container having an aeration floor or perforated tubes along a bottom of the storage container;
• supplying a first concentration of ozone above an upper surface of the second, less dense batch of the grain at a concentration exceeding 200 ppm;
• drawing the ozone into the second, less dense batch of the grain for a first period of time;
• after the first period of time has passed, supplying a second concentration of ozone above the upper surface of the second, less dense batch of the grain for a second period of time, wherein the second concentration of the ozone is less than the first concentration of the ozone, thus producing ozone treated grain;
• removing the ozone treated grain from the storage container;
• and
• blending the ozone treated grain from the storage container with grain that has not been treated with ozone, thus producing a blend of grain having less than 2 ppm of mycotoxins.
