Abstract
A system and method for extracting botanical herbal oil is disclosed. The method includes washing plant material with liquid solvent forming a solvent-oil extract solution, pumping the solvent-oil extract solution to an atomizer, pumping vapor solvent to the atomizer, atomizing the solvent-oil extract solution with vapor solvent forming an atomized mixture, and vaporizing the atomized mixture to isolate the botanical herbal oil from the mixture. The system includes a first pressure vessel to chill a solvent, a second pressure vessel to wash plant material with liquid solvent forming a solvent-oil extract solution, an atomizer to mix the solvent-oil extract solution with vapor solvent forming an atomized mixture, a liquid transfer pump to pump the solvent-oil extract solution to the atomizer, a vapor transfer pump to pump the vapor solvent to the atomizer, and a vaporizer to vaporize the atomized mixture and isolate the botanical herbal oil.
