Reactive gas, reactive gas generation system and product treatment using reactive gas
A method of treating a product or surface with a reactive gas, comprises producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas; transporting the reactive gas at least 5 cm away from the HVCP; followed by contacting the product or surface with the reactive gas. The HVCP does not contact the product or surface.
1. A method of treating food with a reactive gas, comprising:
producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas;
transporting the reactive gas at least 3 meters away from the HVCP; followed by
contacting the food with the reactive gas;
wherein the HVCP does not contact the food,
the food is Salmonella, Listeria , and/or E. coli pasteurized by the contacting, and the reactive gas is gas produced by the HVCP.
2. The method of claim 1 , wherein the food is not sealed or substantially sealed inside a package during the contacting.
3. The method of claim 1 , wherein the food comprises grain.
4. The method of claim 1 , further comprising removing the reactive gas from contact with the food, after 1 second to 12 hours.
5. The method of claim 1 , wherein the reactive gas comprises ozone and at least one nitrogen oxide.
6. The method of claim 1 , wherein the working gas comprises MA65.
7. A method of treating animal feed with a reactive gas, comprising:
producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas;
transporting the reactive gas at least 3 meters away from the HVCP; followed by
contacting the animal feed with the reactive gas;
wherein the HVCP does not contact the animal feed,
the animal feed is Salmonella, Listeria , and/or E. roll pasteurized by the contacting, and
the reactive gas is gas produced by the HVCP.
8. The method of claim 7 , further comprising removing the reactive gas from contact with the animal feed, after 1 second to 12 hours.
9. The method of claim 7 , wherein the working gas comprises MA65.
10. The method of claim 7 , wherein the reactive gas comprises ozone and at least one nitrogen oxide.
11. The method of claim 1 , wherein the food is canning sterilized by the contacting.
12. The method of claim 1 , wherein the contacting is carried out with the food in a fluidized bed.
13. The method of claim 1 , further comprising removing the reactive gas from contact with the food, after 35 minutes to 12 hours.
14. The method of claim 1 , wherein the contacting is carried out with the food moving on a conveyor.
15. The method of claim 1 , wherein the contacting is carried out in a treatment chamber having a volume of at least 1 cubic meter.
16. The method of claim 1 , wherein the food is Salmonella pasteurized by the contacting.
17. The method of claim 1 , wherein the food is Listeria pasteurized by the contacting.
18. The method of claim 1 , wherein the food is E. coli pasteurized by the contacting.
19. The method of claim 7 , wherein the animal feed is canning sterilized by the contacting.
20. The method of claim 7 , wherein the contacting is carried out with the animal feed in a fluidized bed.
21. The Method of claim 7 , further comprising removing the reactive gas from contact with the animal feed, after 35 minutes to 12 hours.
22. The method of claim 7 , wherein the contacting is carried out with the animal feed moving on a conveyor.
23. The method of claim 7 , wherein the contacting is carried out in a treatment chamber having a volume of at least 1 cubic meter.
24. The method of claim 7 wherein the animal feed is Salmonella pasteurized by the contacting.
25. The method of claim 7 , wherein the animal feed is Listeria pasteurized by the contacting.
26. The method of claim 7 , wherein the ea mal feed is E. coli pasteurized by the contacting.
27. A method of treating fruit or seeds with a reactive gas, comprising:
producing the reactive gas by forming a high-voltage cold plasma (HVCP) from a working gas;
transporting the reactive gas at least 3 meters away from the HVCP; followed by
contacting the fruit or seeds with the reactive gas;
wherein the HVCP does not contact the fruit or seeds,
the fruit or seeds is Salmonella Listeria , and/or E. Coli pasteurized by the contacting, and
the reactive gas is gas produced by the HVCP.
28. The method of claim 27 , wherein the fruit or seeds are canning sterilized by the contacting.
29. The method of claim 27 , wherein the working gas comprises MA65.
30. The method of claim 27 , wherein the reactive gas comprises ozone and at least one nitrogen oxide.
31. The method of claim 27 , wherein the fruit or seeds are whole corn or whole wheat.
32. The method of claim 27 , wherein the contacting is carried out with the fruit or seeds in a fluidized bed.
33. The method of claim 27 , further comprising removing the reactive gas from contact with the fruit or seeds, after 35 minutes to 12 hours.
34. The method of claim 27 , wherein the contacting is carried out with the fruit or seeds moving on a conveyor.
35. The method of claim 27 , wherein the contacting is carried out in a treatment chamber having a volume of at least 1 cubic meter.
36. The method of claim 32 , wherein the fruit or seeds are canning sterilized by the contacting.
37. The method of claim 27 , wherein the fruit or seeds are Salmonella pasteurized by the contacting.
38. The method of claim 27 , wherein the fruit or seeds are Listeria pasteurized by the contacting.
39. The method of claim 27 , wherein the fruit or seeds are E. coli pasteurized by the contacting.
40. The method of claim 27 , wherein the fruit or seeds are human food.
