An apparatus with method to conduct extractions from plant matter using liquid Butane as solvent and process quantities ranging from an eighth of an ounce to two ounces is disclosed. The apparatus is meant for individual use offering the convenience of size that allows it to be carried in a backpack, a suitcase, a handbag, a purse or a small bag. It is designed to be operated safely almost anywhere by almost anyone following a few simple instructions without requiring to be versed in the art of extractions using liquid Butane in commercial equipment. The risk of fire is minimized to the risk of using a common cigarette lighter due to the small volume of liquid Butane required to operate the extractor.

This disclosure describes systems, methods, and devices for phytochemical extraction. One example extraction system includes two solvent columns, a material column, and a dewaxing column. The solvent columns store and provide solvent for stripping target chemicals from plant material in the material column. The solvent mixed with target chemicals passes into the dewaxing column, where the target chemicals are separated from waxes and lipids. Cooling is applied to elements of the system by way of an open-loop CO2 refrigeration method. Solvent is moved from the solvent columns to the material column by creating a pressure differential between the two solvent columns.

A process for obtaining enriched fractions of assets from the genus Artemisia, enriched fractions obtained by the process and bioactive composition having fraction enriched from Artemisia. The process uses extraction with supercritical fluid in which the differential consists of sequential extraction, in an unprecedented association of specific conditions and steps with an advantageous effect not previously found, thus obtaining enriched fractions of bioactives with different chemical compositions for a given application. The enriched fractions of assets of the genus Artemisia and/or its so-called bioactive compositions having fraction enriched from Artemisia obtained have application mainly in the pharmaceutical and cosmetic fields.

Disclosed herein is a method for obtaining compounds and compositions from plant and fungus materials by thermal treatment, affinity capture, filtration, and release through multi-phasic transitions between gas, solid, and liquid states. The compounds of interest are obtained by manipulating the temperature and pressure of the heating chamber. The compounds in gas phase are passed through an affinity medium which captures the compounds of interest in either solid or liquid phase by exposing the compound of interest to the localized micro-affinity environment of the medium. The compounds are separated from the medium using direct competition with solvent or buffers optimized for the specific chemical properties of compounds.

An apparatus and method of high pressure treatment of bulk material by extraction and/or impregnation may involve treating bulk material in an internal volume of a pressure vessel apparatus at a high pressure level in a range from 40 to 1000 bar under isolation from the environment. The high pressure treatment may be performed charge-wise in a closed system in the pressure vessel apparatus in that the bulk material is supplied charge-wise to the internal volume with the pressure vessel apparatus closed and is positioned in at least one treatment plane. Upon completion of the high pressure treatment, the bulk material is discharged charge-wise from the internal volume with the pressure vessel apparatus closed. This also gives advantages in terms of handling, especially also with regard to material flow, and with regard to operational reliability.

An apparatus and method for high pressure treatment of bulk material by extraction and/or impregnation may involve high pressure treating bulk material in a high pressure treatment volume of a pressure vessel apparatus at a high pressure level, especially high pressure in the range from 40 to 1000 bar. The method comprises at least the three following step sequences that are each controllable individually: pressurization, high pressure treatment, and depressurization. The high pressure treatment is performed in a continuous manner in the high pressure treatment volume. The high pressure treatment volume or the entire pressure vessel apparatus is in a fixed arrangement during the high pressure treatment. The continuity of the high pressure treatment is ensured solely by means of the high pressure treatment volume. This especially enables engineering optimization of high pressure treatment processes, for example extraction.
