  • Preservation and closed-loop processing for oil extraction of fresh plant materials
    Patent number: 12343367
    Abstract: Devices, systems, and methods are presented that allow processing of fresh plant materials to produce a stabilized liquor that preserves various compounds in the liquor over extended periods of time. Contemplated systems and methods advantageously obviate the need for drying and prevent oxidative and other degradation of valuable components. Moreover, the systems and methods contemplated herein will form a liquor enriched in desired hydrophobic components and depleted of undesired hydrophilic components.

  • Devices and methods for essential oils, terpenes, flavonoids, and hydrosols extraction
    Patent number: 11813549
    Abstract: Devices, systems, and methods are presented that employ high-surface gaseous solvent extraction of terpenoids, essential oil, and/or flavonoids from a liquid raw material at controlled temperature and pressure conditions. In some embodiments, the extraction is based on a rotary or falling film evaporator in which a steam jet is directed at a heated liquid film of raw material at elevated temperatures and reduced pressure.
