METHODS AND SYSTEMS FOR THE SELECTIVE EXTRACTION OF PHYTOCHEMICALS
20230293612 · 2023-09-21 ·

The present application relates to the extraction of phytochemicals, more specifically to methods and systems for the selective extraction of phytochemicals from biomass. A method may comprises placing the biomass into a thermal chamber, the thermal chamber being connected with an eductor through a suction connection, and a discharge port of the eductor being connected to a concentrate tank; generating a vacuum in the thermal chamber by circulating a motive fluid through the eductor; heating the biomass to volatilize one or more phytochemicals; condensing the one or more volatilized phytochemicals by contacting the volatized phytochemicals with the motive fluid; and collecting the one or more condensed phytochemicals into the concentrate tank.

METHOD FOR PREPARING CANNABIDIOL BY SEPARATION AND PURIFICATION USING HIGH-SPEED COUNTERCURRENT CHROMATOGRAPHY
20220009867 · 2022-01-13 · ·

The present invention relates to a method for preparing cannabidiol by separation and purification using high-speed countercurrent chromatography, comprising: alcohol extraction and water precipitation, adsorption with a macroporous resin, and high-speed countercurrent chromatography separation. The present invention separates and obtains high-purity cannabidiol from industrial hemp flowers or leaves, while at the same time removing the psychotoxic component tetrahydrocannabinol by combining a macroporous resin chromatographic column with a high-speed countercurrent chromatograph, and optimizing process parameters, and the solvent used therein being environmentally friendly, leaving no residues, having low cost and being recyclable. Therefore, the method is suitable for industrial production.

Method and apparatus for producing biofuel in an oscillating flow production line under supercritical fluid conditions.

The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

PROCESS FOR SELECTIVELY EXTRACTING CANNABINOIDS FROM CANNABIS PLANT MATERIALS
20220001297 · 2022-01-06 ·

The present disclosure relates to a process for producing a cannabis concentrate from a cannabis plant material via extraction using supercritical carbon dioxide (CO.sub.2) at temperatures in excess of 65° C., thus permitting the selective extraction of tetrahydrocannabinol (THC) over cannabidiol (CBD). Pressures in excess of 4200 psi (289.6 bar) also serve to further selectively extract THC over CBD.

Plant trichome filtration and concentration

Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.
