Methods for creating concentrated plant material solutions
Methods for creating concentrated plant material solution, including combining ethanol-soluble, water-insoluble concentrated plant material with ethanol to define mixtures and reducing the amount of ethanol in the mixtures until the mixtures have viscosities compatible for use with electronic cigarettes. Some examples include combining ethanol-soluble, water-insoluble concentrated plant material, hydrocarbon bases, and liquid solutions containing ethanol to define mixtures, removing the hydrocarbon bases from the mixtures, and reducing the ethanol content of the mixtures until the mixtures define viscosities compatible for use with electronic cigarettes. Some examples include extracting solute from source materials and including the extracted solute in the ethanol-soluble, water-insoluble concentrated plant material.

7. The method of claim 2 , wherein combining the plant material solution with ethanol produces a precipitate that is partially in solution with the mixture; and
further comprising filtering the precipitate out of the mixture.
8. The method of claim 7 , further comprising cooling the mixture below a predetermined precipitate removal temperature to solidify the precipitate out of the plant material solution in the mixture, the precipitate removal temperature being selected to cause the precipitate to separate out of the plant material solution in the mixture.
9. The method of claim 8 , wherein:
the precipitate is a paraffin wax; and
the precipitate removal temperature is selected to cause the paraffin wax to precipitate out of the plant material solution in the mixture.
10. The method of claim 8 , wherein filtering the precipitate out of the mixture includes directing the mixture through a filter defining a pore size of less than 6 microns to remove the precipitate from the mixture.
11. The method of claim 10 , wherein filtering the precipitate out of the mixture includes directing the mixture through a filter defining a pore size of less than 2 microns to remove small particulate impurities from the mixture.
12. The method of claim 1 , wherein the ethanol-soluble, water-insoluble concentrated plant material includes:
a hydrocarbon solvent;
plant material in solution with the hydrocarbon solvent; and
plant material solute extracted from the plant material in solution with the hydrocarbon solvent.
13. The method of claim 12 , further comprising extracting the plant material solute from the plant material.
14. The method of claim 13 , wherein extracting the plant material solute from the plant material includes:
depositing the plant material in a canister;
introducing a canister solvent into the canister;
exposing the plant material to the canister solvent for a predetermined period of time to create an extract mixture including the solute in solution with the canister solvent;
communicating, fluidly, the extract mixture to an extract container, the extract container in fluid communication with the canister;
separating the canister solvent from the extract mixture to define a recycled solvent, including heating the extract container to evaporate the recycled solvent; and
collecting the recycled solvent in a solvent collection container in fluid communication with the extract container.
15. A method for creating a mixture of concentrated plant material and a substantially water-based mixture, comprising:
combining ethanol-soluble, water-insoluble concentrated plant material, a hydrocarbon base, and a liquid solution containing ethanol to define a mixture;
removing the hydrocarbon base from the mixture;
reducing the ethanol content of the mixture until the mixture is primarily water and concentrated plant extract.
16. The method of claim 15 , wherein:
combining ethanol-soluble, water-insoluble plant material concentrate, a hydrocarbon base, and a liquid solution containing ethanol to define a mixture that produces a precipitate;
removing the hydrocarbon base from the mixture includes:
comprising cooling the mixture below a predetermined precipitate removal temperature to solidify the precipitate, the precipitate removal temperature being below the freezing point of the precipitate and above the freezing point of the ethanol-soluble, water-insoluble concentrated plant material, the hydrocarbon base, and the ethanol; and
filtering the precipitate out of the mixture, including directing the mixture through a filter defining a pore size of less than 6 microns.
17. A method for creating a mixture of concentrated plant material and a substantially water-based mixture, comprising:
depositing the concentrated plant material in a canister;
introducing a canister solvent into the canister;
exposing the concentrated plant material to the canister solvent for a predetermined period of time to create an extract mixture including the solute in solution with the canister solvent;
