A filter press used for Ethanol extraction can quickly and efficiently separate biomass from the crude extract. A maceration of groundup hemp or cannabis is mixed with a solvent such as ethanol. The solvent strips out the CBD Oil of the plant fibers, and then the maceration is run through a filter press as a slurry. The biomass is captured between the plates, and the extracted cbd oil can be ...
