Abstract
This disclosure describes systems, methods, and devices for phytochemical extraction. One example extraction system includes two solvent columns, a material column, and a dewaxing column. The solvent columns store and provide solvent for stripping target chemicals from plant material in the material column. The solvent mixed with target chemicals passes into the dewaxing column, where the target chemicals are separated from waxes and lipids. Cooling is applied to elements of the system by way of an open-loop CO2 refrigeration method. Solvent is moved from the solvent columns to the material column by creating a pressure differential between the two solvent columns.
Claims19
A phytochemical extraction system, comprising:
- a first solvent column that includes a jacket that surrounds an inner vessel configured to contain a solvent in a gaseous state, wherein an inlet port of the jacket is connected to a source of pressurized liquid CO2, such that when the liquid CO2 is introduced into the jacket, a first portion of the liquid CO2 boils and a second portion of the liquid CO2 freezes into dry ice snow which accumulates inside the jacket and cools the inner vessel thereby condensing a portion of the gaseous solvent into a liquid state, wherein the first solvent column inner vessel includes an output port;
- and
- a material column that includes a jacket that surrounds an inner vessel that contains plant material, wherein the material column vessel includes an input port that is connected to the output port of the first solvent column inner vessel such that liquid solvent flows via the output port of the solvent column into the material column and washes the plant material, wherein the material column vessel includes an output port.
