Patent ID: 7635665

Claim:
A method for controlling the displacement loss of a chemical formulation when treating crops within a storage facility with an aerosol mixture of a chemical formulation where air intake to an aerosol generator comprises storage facility air in a range of about 10% to about 100% by volume or the mixture and air from outside the storage facility in a range of about 90% to about 0% of the volume of the mixture comprising the steps of: moving air from a gas re-circulation loop disposed within the storge facility through a first conduit to an inlet of an aerosol generator disposed external to the; storage facility generating with the aerosol generator the aerosol mixture of the chemical formulation using the air from the re-circulation loop; moving said aerosol from an outlet of the aerosol generator through a second conduit into the building to the re-circulation loop; and moving the aerosol through the re-circulation loop to treat crops stored within the re-circulation loop with the chemical formulation.
