Abstract
A useful substance is extracted from botanical feedstock by mechanically compressing the feedstock and pumping a solvent through the compressed feedstock at high pressure while applying compressive mechanical force against the feedstock. Movement of pressurized solvent through the compressed feedstock may increase the volume of solvent in contact with the feedstock. Flow of solvent under pressure may also present a shearing force that facilitates dissociation of the useful substance from the feedstock.
Claims23
A method comprising:
- mechanically compressing a botanical feedstock into compressed botanical feedstock;
- pumping a solvent through the compressed botanical feedstock while applying compressive mechanical force against the compressed botanical feedstock, an amount of at least one substance present in the compressed botanical feedstock dissolving into the solvent to produce partially loaded solvent;
- and
- recovering the partially loaded solvent.
1 more element
An apparatus comprising:
- a first solvent reservoir;
- a second solvent reservoir;
- a high pressure pump having an inlet port that is connected to the first solvent reservoir;
- and
- a hydraulic extraction device that is connected to the high pressure pump and the second solvent reservoir, the hydraulic extraction device applying compressive force against a botanical feedstock while solvent is drawn from the first solvent reservoir by the high pressure pump, pressurized by the high pressure pump, passed through the botanical feedstock in the hydraulic extraction device, and captured in the second solvent reservoir.
2 more elements
An apparatus comprising:
- a base having a cylindrical post section;
- the base having a channel formed there through via which a fluid can traverse the post;
- and
- a cylindrical bore adapted to be temporarily mounted to the cylindrical post section of the base;
- and
- a cylindrical ram adapted to move slidably into the cylindrical bore, the ram having a channel formed there through via which a fluid can traverse the ram.
