Short-path distillation is a technique used when the distillate travels a short distance at a reduced pressure in order to separate a liquid into different compounds to receive its desired materials. Short-path distillation allows different cannabis compounds such as CBD and THC to be separated from the untreated cannabis oil. After separation the compounds such as the CBD and THC can reach purity levels of over 80%. Untreated cannabis oil is heated to a certain temperature in which the solution evaporates and the THC and CBD vapor will rise to the top of the distillation unit. After it is condensed back into a liquid it successfully separates from the other substances.
When using a vacuum pump instead of heat to reduce the pressure and point of distillation taking place, the liquid mixture will be then be separated into the different compounds. There are a few different pumps that are the most applicable for cannabis distillation and can include diaphragm pumps, rotary vane pumps, hybrid pumps, diffusion pumps, oil-sealed pumps, turbo pump and dry-screw pumps. Those types of pumps have the specific power to pull a deep enough vacuum to separate the untreated cannabis oil into the two various different compounds.
