NOVELTY - A pyrolysis machine for pyrolytic processing of biomass material into useful byproducts comprises a pair of axially parallel, rotating rollers in an enclosure, wherein the rollers are narrowly spaced-apart to grab and crunch the biomass material fed between them; heating mechanism for heating the rollers to an incinerating temperature; and feed mechanism for feeding the biomass material between the rollers.    USE - For pyrolytic processing of biomass material into useful byproducts (claimed), e.g. oils and other liquids and carbon particles and other solids, wherein the biomass material is e.g. vegetation, paper or worn tires.    ADVANTAGE - The invention accomplishes pyrolysis in a single and continuous operation which is easily controlled and self-regulating, at a great economy of energy.    DETAILED DESCRIPTION - A pyrolysis machine for pyrolytic processing of biomass material (2) into useful byproducts comprises an enclosure (5); a pair of axially parallel, rotating rollers (3, 4) in the enclosure, wherein the rollers are narrowly spaced-apart to grab and crunch the biomass material fed between them; rotation mechanism for the rollers; heating mechanism for heating the rollers to an incinerating temperature; feed mechanism for feeding the biomass material between the rollers; and extraction mechanism for extracting the byproducts from the enclosure. An INDEPENDENT CLAIM is also included for a pyrolytic method for converting biomass material into useful byproducts, which comprises ablating and pyrolyzing the biomass material between highly heated, counter-rotating crunching rollers.
