Distillation of Hemp and Cannabis

Most crude hemp and cannabis oils processed in our distillation systems are typically derived from either supercritical CO2 Extraction, Hydrocarbon Extraction or Ethanol Extraction. The quality of the extract will have an impact on the downstream distillation, and impurities such as water or ethanol may preclude obtaining the high vacuum levels necessary to concentrate CBD or THC as distillates and need to be removed first. Also, acid precursors to CBD and THC, known as CBDA and THCA, must be decarboxylated before conducting high vacuum distillation.

Once ready, the oil is introduced into the evaporator and distilled in two fractions: The residue fraction, mostly comprised of chlorophyll and other triglycerides, is dark in colour and is ultimately discarded; and the distillate fraction, predominantly comprised of CBD and/or THC along with other cannabinoids, with its light golden colour, is the desired product. Terpenes are also collected, but due to their light molecular nature are predominantly collected in the cold trap.
