US Patent:

20200009205, Jan 9, 2020

Filed:

Aug 23, 2019

Appl. No.:

16/550145

Inventors:

Jose RIVAS - San Francisco CA, US

International Classification:

A61K 36/185

Abstract:

In a multi-step process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step of the process provides a low-temperature, robust essential oil/terpene capture that also dehydrates and decarboxylates the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. By doing the terpene capture under vacuum distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids. The process includes additional steps of: extract cannabinoids from the dehydrated cannabis to produce a crude extract via a supercritical CO2 extraction process; purify crude extract of fats, lipids, plant material; and distill relevant cannabinoids from the purified crude extract via a wiped-film process. Selected terpenes and cannabinoids are then recombined in predetermined proportions to achieve extracts of unusual purity and having targeted therapeutic profiles.

Abstract:

In a system and process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step provides a low-temperature, robust essential oil/terpene capture that also dehydrates and decarboxylates the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. By doing the terpene capture under vacuum distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids. The system includes an oil/water separator configured to prevent leakage of ambient air into the system.

International Classification:

H01P 1/213
H01P 1/161
H01P 1/17
H01P 1/165

Abstract:

A method includes receiving, through a vertical polarization port of an orthogonal-mode transducer (OMT), a vertical polarized signal from a vertical polarization diplexer, and receiving, through a horizontal polarization port of the OMT, a horizontal polarized signal from a horizontal polarization diplexer. The method also includes receiving, through a common port of the OMT, a circular polarized signal comprising the vertical and horizontal polarized signals. The common waveguide includes a septum polarizer configured to split or combine between the circular polarized signal, and the vertical polarized signal and the horizontal polarized signal.
