how does it work? the co2 from the dry-ice in the cryogenic tumbler “tumble freeze dries†the plant material by acting like a rotating pump to remove the water from the air surrounding the raw plant material. the cryogenic tumbler simply amplifies the “freeze fracturing†effect by applying stress and agitating the materials into smaller particulates at these very low temperatures lipid oils are broken down into a paraffin waxy powder which is extracted and then easily compacted by the extraction contraption. watch the short 2 minute video, seeing is believing! http://www.durokon.com/zenport-plant-essence-lipid-oil-extraction-contraption
