Extraction devices, systems, and methods

An extraction device, comprising:

• a solvent reservoir having a top surface, sidewalls, and a bottom surface, the solvent reservoir including a solvent inlet valve and a solvent return port positioned on the top surface and at least two spacers attached to the bottom surface, the solvent reservoir structured to store a solvent that includes butane having a solvent volume within the solvent reservoir;
• a solvent reservoir thermal housing surrounding the sidewalls and the bottom surface of the solvent reservoir, the solvent reservoir housing spaced apart from the sidewalls and the bottom surface by a gap configured to store a cold bath, the at least two spacers positioned to support the gap between the bottom surface and the solvent reservoir thermal housing;
• a solvent release valve configured to release at least a portion of the solvent from the solvent reservoir;
• a solvent sanitary fitting fittingly engaged with and positioned vertically below the solvent reservoir, the solvent sanitary fitting configured to receive at least a portion of the solvent released through the solvent release valve;
• a plant material reservoir disposed vertically below the solvent reservoir and the solvent sanitary fitting, the plant material reservoir fittingly engaged with the solvent sanitary fitting and structured to receive the released solvent from the solvent sanitary fitting, the plant material reservoir structured to house cannabis plant material and to expose the cannabis plant material to the released solvent to produce a cannabinoid-solvent solution of extracted cannabinoids and excess solvent;
• a plant material temperature control jacket configured to receive a warm/hot bath that heats the plant material reservoir or a cold bath that cools the plant material reservoir;
• a plant material reservoir release valve configured to release at least a portion of the cannabinoid-solvent solution from the plant material reservoir;
• a plant material sanitary fitting fittingly engaged with and positioned vertically below the plant material reservoir, the plant material sanitary fitting configured to receive at least a portion of the cannabinoid-solvent solution released through the plant material reservoir release valve;
• a collection reservoir having a top surface, sidewalls, and a bottom surface with at least two spacers attached to the bottom surface, the collection reservoir disposed vertically below the plant material reservoir and the plant material reservoir sanitary fitting, the collection reservoir fittingly engaged with the plant material sanitary fitting and structured to receive the cannabinoid-solvent solution;
• a collection reservoir thermal housing surrounding the sidewalls and the bottom surface of the collection reservoir, the collection reservoir housing spaced apart from the sidewalls and the bottom surface by a gap configured to store a warm/hot bath, the at least two spacers positioned to support the gap between bottom surface and the housing of the collection reservoir;
• a collection reservoir release valve configured to release at least a portion of gaseous phase solvent separated from the cannabinoid-solvent solution from the collection reservoir;
• a collection reservoir-solvent return sanitary connector having a first end attached to the collection reservoir release valve and a second end;
• and
• a solvent return extending between and attached to the second end and the solvent return port of the solvent reservoir, the solvent return structured to provide a pathway for the gaseous phase solvent to travel from the collection reservoir to enter the solvent reservoir, wherein the solvent return comprises flow flow control features selected from the group consisting of a flow regulating valve, a purge valve, and a combination thereof;
• and
• wherein the solvent reservoir, the plant material reservoir, the collection reservoir, and the solvent return form a sealed, closed-cycle extraction environment.

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, 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;
• and
• wherein the solvent chamber, the plant material chamber, the collection chamber, and the solvent return form a sealed, closed-cycle fluid pathway.
