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.

First claim

What is claimed and desired to be secured by Letters Patent is:

1. A method of treating a problem location of grain stored in a grain pile comprising:
piling the grain outdoors, thus producing the grain pile;
covering the grain pile with a covering;
monitoring temperature and/or odor of the grain pile;
upon detecting an abnormal temperature variance and/or an abnormal odor, determining the problem location in the grain pile;
creating an access hole in the covering proximate the problem location;
inserting a tube into the problem location of the grain pile through the access hole;
applying ozone through the tube to the problem location within the grain pile; and
removing the tube from the grain pile.

2. A method of treating grain as recited in claim 1 , wherein the method reduces one of: mold; and toxin.

3. A method of treating grain as recited in claim 1 , wherein a concentration of the ozone applied through the tube exceeds five thousand parts per million.

4. A method of treating grain as recited in claim 1 , wherein a concentration of the ozone applied through the tube exceeds ten thousand parts per million.

5. The method of treating grain as recited in claim 1 , further comprising patching the access hole.

6. The method of treating grain as recited in claim 1 , further comprising monitoring temperature at a plurality of locations of the grain pile.

7. The method of treating grain as recited in claim 1 , further comprising:
placing a retaining structure and an aeration outlet where the grain pile is to be placed; and
piling the grain within the retaining structure such that the aeration outlet is located with the grain.

8. The method of treating grain as recited in claim 7 , further comprising forcing air into the grain pile through the aeration outlet.

9. The method of treating grain as recited in claim 7 , further comprising drawing air out of the grain pile through the aeration outlet.

10. The method of treating grain as recited in claim 1 , wherein the covering is a tarp or plastic.

11. A method of treating a problem location of grain stored in a grain pile comprising:
monitoring temperature and/or odor of the grain pile;
upon detecting an abnormal temperature variance and/or an abnormal odor, determining the problem location in the grain pile;
inserting a tube into the problem location of the grain pile;
applying ozone having a concentration of at least 5000 ppm through the tube to the problem location within the grain pile; and
removing the tube from the problem location of the grain pile.

12. A method as recited in claim 11 , further comprising:
covering the grain pile with a covering;
creating an access hole in the covering of the grain pile; and
inserting the tube through the access hole.

13. The method of treating grain as recited in claim 12 , further comprising patching the hole in the covering.

14. The method of claim 12 , wherein the covering is a tarp or plastic.

15. A method of treating grain as recited in claim 11 , further comprising piling the grain outdoors, thus producing the grain pile.

16. The method according to claim 11 , further comprising:
placing a vapor barrier on ground;
placing a retaining structure on the ground; and
placing the grain on the vapor barrier and within the retaining structure, thus producing the grain pile.
