Abstract
Embodiments of the inventive technology may be described as a plant biomass extraction apparatus for production of liquid extract from plant biomass, using carbon dioxide, including one or more of: carbon dioxide chiller, extraction chamber, extract collection chamber, at least one valve, and fluid conveyance componentry, configured to define a closed loop for passive, pump-free extract production. Certain embodiments may avoid saturation of the extractant, and the resultant compromise of process effectiveness that may be seen in those apparatus relying on mechanical pump(s) for flow and/or may present a tabletop, closed loop liquid carbon dioxide extraction apparatus for the production of an extract from plant biomass or other matrix.
Claims20
A plant biomass extraction apparatus for production of liquid extract from plant biomass, comprising:
- a carbon dioxide chiller configured to chill carbon dioxide, said carbon dioxide exiting said chiller as liquid carbon dioxide;
- an extraction chamber established downflow of said carbon dioxide chiller, and configured to contain said plant biomass for extraction, said liquid carbon dioxide contacting said plant biomass to generate a liquid carbon dioxide-liquid extract mixture;
- an extract collection chamber established downflow of said extraction chamber;
- a heater configured to heat said liquid carbon dioxide-liquid extract mixture in said extract collection chamber to convert at least some of said liquid carbon dioxide of said liquid carbon dioxide-liquid extract mixture in said extract collection chamber to gaseous carbon dioxide, said liquid extract remaining in said extract collection chamber;
- and
- fluid conveyance componentry that fluidically couples said carbon dioxide chiller, said extraction chamber and said extract collection chamber to define a closed loop, said apparatus being pump free and operable to produce said extract from said plant biomass via passive, pump-free, closed loop processing.
