Claims21
A cannabis oil extraction method, the method comprising:
- performing grinding assisted extraction comprising:
- grinding plant material in the presence of solvent to generate an extract process material mixture;
- performing co-solvent extraction using subcritical CO2 comprising:
- adding liquid CO2 to the extract process material mixture, and maintaining the extract process material mixture at a temperature and pressure combination sufficient to maintain the liquid CO2 in a subcritical state;
- degassing the CO2;
- and
- separating the extract process material mixture by centrifugation.
