Extraction devices, systems, and methods

摘要

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.

主权项

1. An 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-plant material chamber connector having a first end and an opposing second end, the first end attached to the solvent chamber and structured to receive solvent released from the solvent chamber; a plant material chamber attached to the second end of the solvent chamber-plant material chamber connector, the plant material chamber in fluid communication with the solvent chamber and structured to receive the solvent released from the solvent chamber, the plant material chamber structured to house plant material and to expose the received solvent to the plant material to produce a solvent-extract solution; a plant material chamber-collection chamber connector having a first end and an opposing second end, the first end attached to the plant material chamber and structured to receive the solvent-extract solution from the plant material chamber; a collection chamber attached to the second end of the plant material chamber-collection chamber connector, the collection chamber in fluid communication with the plant material chamber and structured to receive the solvent-extract solution from the plant material chamber, the solvent-extract solution including extracted plant material extracts produced from the exposure of the solvent to the plant material and solvent; a collection chamber-solvent return connector having a first end and a second end, the first end 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 end of the collection chamber-solvent return connector 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, the solvent return positioned to extend into the solvent chamber; wherein the solvent chamber, the plant material chamber, the collection chamber, and the solvent return form a sealed, closed-cycle fluid pathway.
