Independent claims
What is actually asserted, verbatim.
1. A safer and more reliable extraction process for extracting cannabinoids and to reduce chlorophyll and wax co-extraction from a cannabis, or hemp plant substrate comprising, wherein the process excludes use of liquid carbon dioxide, in combination, (i) pre-processing comprising lowering the temperature of a solvent to a range of −30 degrees C. to −50 degrees C., (ii) contacting at −30 degrees C. to −50 degrees C., wherein there is a contacting time between the cannabis plant substrate and the solvent to create an emulsion, (ill) evaporating for reduction of the emulsion by means of atmospheric evaporation of the solvent, (iv) recovering for recovery of the solvent from the emulsion, (v) purging under vacuum to remove remaining solvent from the extract whereby a resu tory extract is substantially free of any lipids and chlorophyll, wherein optionally, (a) the solvent is 95% ethanol and 5% of a solvent that is another solvent that does not comprise ethanol, or (b) the solvent is at least one solvent-like material selected from the group consisting essentially of heptane, hexane, isopropyl alcohol, and menthanol.
