Abstract
The separation of essential oils from a botanical biomass can be accomplished in a more effective way and with higher yields using microwaves to extract essential oils by dry or azeotropic distillation and isolating products from the essential oils.
Claims13
A solvent free method for the extraction of essential oils from a botanical biomass comprising:
- a) placing the botanical biomass in a microwave applicator;
- b) introducing an inert gas into the microwave applicator sufficient to purge oxygen from the microwave applicator;
- c) introducing microwave emissions from a microwave transmitter into the microwave applicator, wherein the microwave transmitter is kept at a temperature from about 5° C. to about 25° C. with the temperature in the microwave applicator kept at about 100° C. to about 200° C., until the essential oils from the botanical biomass are vaporized and extracted from the botanical biomass by dry distillation in a low oxygen atmosphere or by azeotropic distillation with the residual water in the botanical biomass;
- d) condensing the vaporized essential oils from the microwave applicator to liquid essential oils;
- and
- e) collecting the liquid essential oils and exhausting non-condensable gases by vacuum pump.
