Abstract
Extraction devices, methods, and systems are disclosed. Example devices have a solvent chamber, a plant material chamber, a collection chamber, and a solvent return that create a sealed, closed-cycle extraction and/or solvent purification process. Any extractable plant material can be used in the disclosed devices, methods, and systems although in some examples some form of the cannabis plant is used.
Claims28
A cannabinoid extraction device, comprising:
- a solvent chamber having a solvent chamber return inlet, the solvent chamber structured to store a solvent having a stored solvent volume;
- a solvent chamber-cannabinoid containing plant material chamber interface having a first side and an opposing second side, the first side attached to the solvent chamber and structured to receive solvent released from the solvent chamber;
- a cannabinoid containing plant material chamber attached to the second side of the solvent chamber-cannabinoid containing plant material chamber interface, the cannabinoid containing plant material chamber in fluid communication with the solvent chamber and structured to receive the solvent released from the solvent chamber, the cannabinoid containing plant material chamber structured to house cannabinoid containing plant material and to expose the received solvent to the cannabinoid containing plant material to produce a cannabinoid containing solvent-extract solution;
- a cannabinoid containing plant material chamber-collection chamber interface having a first side and an opposing second side, the first side attached to the cannabinoid containing plant material chamber and structured to receive the solvent-extract solution from the plant material chamber;
- a collection chamber attached to the second side of the cannabinoid containing plant material chamber-collection chamber interface, the collection chamber in fluid communication with the cannabinoid containing plant material chamber and structured to receive the cannabinoid containing solvent-extract solution from the cannabinoid containing plant material chamber, the cannabinoid containing solvent-extract solution including at least a cannabinoid produced from the exposure of the solvent to the cannabinoid containing plant material;
- a collection chamber-solvent return interface having a first side and a second side, the first side of the collection chamber-solvent return connector attached to the collection chamber and structured to receive the solvent in a gaseous form;
- and
- a solvent return attached between the second side of the collection chamber-solvent return interface and the solvent chamber return inlet, the solvent return structured to provide fluid communication between the collection chamber and the solvent chamber and to provide a pathway for the gaseous solvent to return to the solvent chamber, wherein the solvent return comprises flow control features selected from the group consisting of a flow regulating valve, a purge valve, or a combination thereof;
- and
- wherein the solvent chamber, the cannabinoid containing plant material chamber, the collection chamber, and the solvent return form a sealed, closed-cycle fluid pathway.

A cannabinoid extraction device, comprising:
- a solvent chamber having a solvent chamber return port, the solvent chamber structured to store a solvent having a stored solvent volume;
- a solvent chamber-cannabis plant material chamber interface having a first side and an opposing second side, the first side attached to the solvent chamber and structured to receive solvent released from the solvent chamber;
- a cannabis plant material chamber attached to the second side of the solvent chamber-cannabis plant material chamber interface, the cannabis plant material chamber in fluid communication with the solvent chamber and structured to receive the solvent released from the solvent chamber, the cannabis plant material chamber structured to house cannabis plant material and to expose the received solvent to the cannabis plant material to produce a cannabinoid containing solvent-extract solution;
- a cannabis plant material chamber-collection chamber interface having a first side and an opposing second side, the first side attached to the cannabis plant material chamber and structured to receive the cannabinoid containing solvent-extract solution from the cannabis plant material chamber;
- a collection chamber attached to the second side of the cannabis plant material chamber-collection chamber interface, the collection chamber in fluid communication with the cannabis plant material chamber and structured to receive the cannabinoid containing solvent-extract solution from the cannabis plant material chamber, the cannabinoid containing solvent-extract solution including at least an extracted cannabinoid produced from the exposure of the solvent to the cannabis plant material;
- and
- a solvent return attached between the collection chamber and the solvent chamber return port, the solvent return structured to provide fluid communication between the collection chamber and the solvent chamber wherein the solvent return comprises flow control features selected from the group consisting of a flow regulating valve, a purge valve, and a combination thereof;
- wherein the solvent chamber, the cannabis plant material chamber, the collection chamber, and the solvent return form a sealed, closed-cycle fluid pathway.
