Abstract
An improved process for producing refined oils free of contaminating waxes, resins, and lipids from botanical plant matter using an improved in-line winterization process is disclosed. The biomass is fed into an extraction vessel where the oils are extracted using a solvent, followed by a two-stage separation. Both the temperature and pressure of the solvent going into the separators are controlled for effective separation. Additional solvent is added to enhance the separation efficiency between the refined oil and the undesired fraction containing the contaminants. This process provides an alternative to current wax mitigation techniques, such as alcohol based solvent winterization.
