A method of extracting an essential oil from plant matter, starting with providing plant matter to an interior of an extraction vessel, wherein the plant matter includes at least one essential oil. Next, at least one vacuum pump is used to reduce the pressure within the interior of the extraction vessel with the plant matter therein to an absolute pressure of less than 400 mm Hg absolute pressure. Microwave energy is applied to the plant matter while the interior of the extraction vessel is under the reduced pressure, thereby forming a vapor including at least a portion of the essential oil. The vapor is directed from the extraction vessel to at least one condenser vessel. Finally, the vapor is condensed to a liquid state such that the vapor includes at least a portion of the essential oil, by utilizing the at least one condenser vessel.

The disclosed embodiments include systems and methods for the solvent extraction of a substance from a material. The disclosed systems include multiple tanks and an extraction chamber in communication with the tanks. Solvent transport is accomplished by heating and/or cooling selected tanks to cause the solvent to be transported between tanks.

In a system for perorming 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 process for dehydrating and decarboxylating the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. An important by-product of the dehydration/decarboxylation is a terpene-rich distillate. 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.

A system and method for extracting essential oils is provided. One embodiment comprises an extractor assembly with an extractor cover, an extractor container, and an extractor assembly base, wherein the extractor container is secured between the extractor cover and the extractor assembly base during an extraction process; a bowl cover assembly with a collection bowl, and a bowl cover assembly base, wherein the collection bowl is secured between the extractor assembly base and the bowl cover assembly base during the extraction process; and a canister compression holder assembly, wherein a cannister containing a solvent is secured within the canister compression holder assembly during the extraction process. A solvent that is released from the cannister passes into the extractor container that contains matter that is to have essential oils extracted therefrom. The extracted oils exits the extractor assembly base into the collection bowl that collects the solvent with the essential oils.

A device for automatic extraction, storage and encapsulation of fatty compounds, the device may include: an extraction unit configured to provide a liquid mixture comprising fatty compounds extracted from biological material and a liquid solvent; an evaporation and reaction unit; a storage unit comprising one or more storage outlet ports; and a controller configured to: control delivery of the liquid mixture from the extraction unit to the evaporation and reaction unit; control evaporation of the solvent from the liquid mixture in the evaporation and reaction unit; control delivery of the liquid mixture from the evaporation and reaction unit to the storage unit; detect safe connection of each of at least one of one or more capsules to one of the one or more storage outlet ports of the storage unit; and control filling of at least one of the one or more connected capsules with the liquid mixture.

The present disclosure discloses a method for extracting a plant essential oil with dual auxiliaries, which includes: using an aromatic plant as a raw material, adding an extracting liquid prepared from the dual auxiliaries and water, stirring evenly for raw material wetting back, then distilling and collecting the essential oil, where the dual auxiliaries include a component A and a component B, the component A includes at least one of choline chloride and betaine, and the component B includes at least one of a natural acid, an amine, an alcohol and a saccharide.

A method of modifying a naturally occurring Cannabis raw plant material, a purified Cannabis product from a naturally occurring Cannabis raw plant material, and a modified Cannabis product from a naturally occurring Cannabis raw plant material. The method includes selectively extracting at least some volatile organic compounds from a naturally occurring Cannabis raw plant material. At least some of a naturally occurring potential cannabinoid content in the Cannabis raw plant material is retained after removal of the at least some of the volatile organic compounds as well as substantially all of the physical structure of the Cannabis raw plant material.

An organic based extraction system is described. Embodiments of the extraction system include a first vessel, a second vessel, a third vessel, a pump, and a plurality of sight lenses. Generally, each of the vessels and the pump can be set up to form a closed loop system adapted to recover and reuse a solvent. A fluid flow from the first vessel to the second vessel, from the second vessel to the third vessel, from the third vessel to the pump, and from the pump back to the first vessel can be implemented. Typically, an extract from organic matter can be recovered in the third vessel. In one embodiment, the plurality of sight lenses can be implemented to determine if more solvent is needed and to check the extract while an extraction process is running.

A two stage system for extraction of oil from whole citrus fruit is provided. The first stage is known in the art and includes a first plurality of toothed rollers which convey citrus as the teeth penetrate and rupture oil glands. The oil passes into a first water pan. A novel second stage uses a second plurality of toothed rollers to continue the penetration and rupturing of oil glands. The second plurality of rollers are positioned in an isolated second pan to partially submerge the citrus. A middle phase liquor with extremely low oil concentration is transferred into said second pan to initiate desorption of oil from the citrus. The desorption technique in one embodiment increases yield by 4% or more. This technique is expected to increase yield even more as the recovery by the first stage is reduced.

The present invention relates to the field of perfumery, that is, the art or process of making a fragrant substance be it natural or synthetic.

The present invention discloses a method of obtaining a better reconstituted absolute NNA+ (Near Natural Absolute) comprising the steps of: a) mixing a synthetic absolute or raw reconstituted absolute with an alcohol; b) freezing the solution of step (a); c) filtering the solution of step (b) through a propylene cloth to separate out non-alcohol soluble substance and to obtain a crystal clear percolate; d) transferring the percolate obtained from step (c) to an alcohol extraction unit, where said solution is boiled in a glass vessel at high temperature and vacuum to separate the alcohol; e) allowing the solution of step (d) to stand for maturation of the reconstituted absolute NNA+.
