An extraction system comprises an extraction chamber having an end cap at an one end accepting organic matter and gas or liquid solvent. A collection vessel is attached below the extraction chamber, a viewing vessel is sealed at an acute angle to a sidewall of the collection vessel enabling visual inspection at the collection plate. A gas tank is connected to the extraction chamber introducing solvent and a frame supports chamber by axles fixedly mounted on opposite sides of the extraction chamber, said axles supported by the frame structure enabling free rotation of the chamber about the axles. After gas is introduced to the organic matter, the extraction chamber is rotated vigorously about the axis, the one end is then connected to the open upper end of the collection vessel, and a lipid yield is collected at the collection plate.

A cannabidiol extraction and conversion process includes an extraction process including a sizing unit wherein raw Cannabis plant material is reduced to a uniform size, a blending unit wherein an extraction solvent is blended together with the Cannabis plant material to form an initial extract, and a primary solvent exchange rotary evaporator unit wherein an exchange solvent is added to the initial extract, and a processed extract rich in cannabidiol is obtained. A conversion process includes a conversion rotary reflux unit wherein the processed extract is combined and processed with an acidic component, a separator unit wherein a solvent is added and a separator organic effluent is obtained, a secondary solvent exchange rotary evaporator unit wherein a further solvent is added, and a fractionation unit wherein the tetrahydrocannabinol obtained is separated into a plurality of functional fractions for selective blending.

Described herein are examples of centrifuges. A centrifuge may include a basin to contain a solvent and a biomass. The centrifuge may further include a lid connected to the basin via a hinge and configured to selectively close a top opening of the basin. The centrifuge may further include circular basket disposed within the basin. The centrifuge may further include a balancing ring to counterbalance contents of the basin. The balancing ring may include two or more spherical weights and a race configured to receive the two or more spherical weights and configured to permit the two or more spherical weights to move within the race while the centrifuge is spinning, thereby counterbalancing the contents of the basin.

A method for extracting resins and oils from a plant includes: 1) tumbling, inside a container at a temperature of at most 50 degrees Fahrenheit with a tumbler, plant fibers having one or more portions that contain resins and/or oils; 2) colliding the tumbler with the plant fibers to release the one or more portions that contain resins and/or oils from the remainder of the plant fibers; and 3) segregating the one or more portions that contain resins and/or oils from the remainder of the plant fibers.

A system and method for extracting essential oils from organic material is provided. One embodiment places organic material into an extraction chamber that is a cylindrical wall of rigid material, wherein a diameter and a height of the extraction chamber is sized to define an interior that accommodates a desired amount of an organic material having essential oils; fills the extraction chamber with a solvent after the organic matter has been placed into the extraction chamber; and moves a vortex plunger disposed over the surface of the organic material in a repeated upward and downward motion during an agitation process so that the vortex vanes generate a fluid vortex in the solvent, wherein the fluid vortex causes the solvent to be drawn upward into the organic material and then to be pushed downward through the organic material so that the solvent extracts essential oils from the organic material.

An apparatus for extracting organic compounds from plant materials using subcritical or supercritical carbon dioxide is described. The apparatus has a sealable pressure chamber into which carbon dioxide dry ice and the plant materials are inserted, the pressure chamber, once sealed, self-pressurizing as the container and contents are warmed to a chosen temperature, converting the solid CO.sub.2 to liquid, or to a super-critical fluid as the temperature and pressure are raised above the Critical Point. The chamber can be rotated when subcritical CO.sub.2 liquid is employed to improve mixing between the liquid and the plant material. After a suitable extraction time, the carbon dioxide solvent containing the extracted material is directed into a separator such that the carbon dioxide and extracted material can be effectively separated, thereby avoiding significant quantities of viscous and waxy extracted materials remaining in the chamber and valves after the carbon dioxide solvent is warmed and allowed to exit the chamber.

The present disclosure is generally directed to the extraction of active compounds from plant biomass. In particular, the present disclosure is directed to the extraction of active compounds from plant biomass using solvents of different polarity.

In a process for removing dyes from a textile material, comprising or consisting of polyester fibers, or comprising or consisting of cotton fibers, a batch of said textile material is reduced to clippings having small size, treated with a solvent under stirring in an extraction chamber and centrifugated to remove the solvent, the solution comprising solvent and extracted material is used as a solvent to extract dye from another batch of textile material.

A system for extracting substances from a source material includes a chamber assembly, one or more ultrasonic transducers, and one or more convective mixing mechanisms. The chamber assembly defines a chamber. The chamber is configured to hold source material and a solvent such that at least a portion of the source material is immersed in the solvent. The one or more ultrasonic transducers are configured to produce ultrasonic waves that impinge on at least a portion of the portion of the source material in the solvent. The one or more mixers are configured to mix at least a portion of the source material.
