Low temperature ethanol extraction machine is specifically for extracting winterized and decarboxylated oil from hemp or cannabis. The machine is a whole continuous production line, it include ethanol cooling, extraction, fine filtration, first stage ethanol evaporation, second stage ethanol evaporation, decarboxylation, vacuum part, etc. Due to the extraction temperature can be less than -73℃, so the final oil is well winterized and good quality.
