Ethanol Extraction Equipment

Ethanol Extraction systems use food grade or USP grade ethanol as a solvent to extract plant  or cannabis material. Methods varies from vessels to reactors, filter reactors, spinning vessels to barrels. A popular process has the ethanol chilled to <-20°C (-4°F) either in a cold room or freezer and then pumped into a container of cannabis.

The ethanol solution is used to soak and is either filtered or the plant or cannabis material removed. The resultant mother liquor of ethanol and extract is then concentrated by removing the ethanol. Typical distillation apparatus used to remove the ethanol include rotary evaporators, falling film evaporators or a batch vacuum distillation system.
