The present invention is directed to a method for preparing plant extracts comprising the steps of (i) preparing a soluble extract from (a) plants or parts thereof and (b) an aqueous, alcoholic or aqueous alcoholic mixed extractant; and removal of insoluble components, (ii) concentrating the extract to a dry substance content at which the contained lipids and lipoids form suspended and/or emulgated aggregates, (iii) separating the suspended and/or emulgated aggregates by microfiltration from the concentrated extract, and (iv) optionally removing the extractant. The invention further pertains to an extract and composition comprising said extract as prepared by this method.

A process for preparing a total extract which is a mixture of a fresh plant matter with a fatty matter includes a. contacting the fresh plant matter which comprises at least 10% of water by weight relative to its total weight before or after desiccation loss, with the fatty matter chosen from hydrogenated oil or fat at a temperature between 50° C. and 180° C.; b. grinding the plant matter-fatty matter mixture at said temperature between 50° C. to 180° C.; and c. recovering a total extract that is solid or liquid at ambient temperature with a concentration of less than or equal to 4% of water by weight relative to the total weight of the total extract. Extracts recovered from such process and treatments using the extracts are also disclosed.

A method of producing pure cannabidiol (CBD) isolate crystals including the steps of extracting the CBD compound from a cannabis plant; winterizing to remove fats, waxes and chlorophyll from the CBD extract; filtering the CBD extract through a series of filter plates; removing carboxylic acid and CO2 from the CBD extract; removing impurities from the CBD extract by distillation; and crystallizing the purified CBD extract to produce pure CBD isolate crystals and chopping the pure CBD isolate crystals to produce crystals of between 200 and 600 microns in size. A further embodiment includes the steps of grinding the crystals to produce micro-particles of between 1 and 5 microns and releasing the micro-particles into an air environment.

An apparatuses used for the safe dispensation of compressed liquid/gas butane from a compressed liquid/gas butane can for use in mixing this liquid/gas with parts of a marijuana plant within a glass tube of the apparatus to thereby remove the THC from the marijuana plant and disposing it and the residual liquid/gasses into a capture member for further processing.

The system and method of the present invention provides an automated washing and extraction system and method to removed trichomes from cannabis product to create hash resin. Inconsistency is removed from the hash extraction process by automating the washing and extraction cycles thereof. The system and method records the data and tracks all user functions. Manual labor is removed or significantly reduced and time to create the final product is greatly lessened. Thus, more hash can be produced in a shorter amount of time. Moreover, the present invention allows the end user a controlled and accurate and efficient way of producing large quantities of solvent-free hash in a short amount of time while doing so in a consistent, repeatable and cost-effective manner.

The invention provides a composition comprising 1,1-difluoroethene (R-1132a); a second component selected from the group consisting of hexafluoroethane (R-116), ethane (R-170) and mixtures thereof; and, optionally carbon dioxide (CO.sub.2, R-744).

The present invention describes a method and an automatic system for recovering protein powder meal, crude and pure omega-3 oil and purified distilled water from a mixture of animal tissue processed in a filter-drier-reaction tank. Animal tissue, for example fish, and organic solvent are directly or indirectly fed into the filter-drier-reaction tank. The filter-drier-reaction tank mixes, heats, and separates solid and heavy liquid portions of the mixture, the organic solvents are automatically recycled back in to the system after distillation. The solid portion is retained in the filter-drier-reaction tank and baked. Solid protein powder product (the protein powder meal) is thus recovered.

A closed loop extraction system for extracting desired components from raw plant matter and method of use is disclosed. The closed loop extraction system features a solvent source, a chill tank, a wash tank, a rinse tank, a centrifuge, and a feed tank all in fluid communication via a series of interconnected pump systems. The method of extracting the desired products from raw plant matter uses this system to perform the extraction with a reduced amount of solvent in an energy-efficient manner.

Provided are methods for selective extraction of cannabinoids, for example cannabidiol (CBD), from a plant source, by using tailored extraction media.

A super strong and tough densified wood structure is formed by subjecting a cellulose-based natural wood material to a chemical treatment that partially removes lignin therefrom. The treated wood retains lumina of the natural wood, with cellulose nanofibers of cell walls being aligned. The treated wood is then pressed in a direction crossing the direction in which the lumina extend, such that the lumina collapse and any residual fluid within the wood is removed. As a result, the cell walls become entangled and hydrogen bonds are formed between adjacent cellulose nanofibers, thereby improving the strength and toughness of the wood among other mechanical properties. By further modifying, manipulating, or machining the densified wood, it can be adapted to various applications.
