NOVELTY - Organic material treatment apparatus (1) comprises combustion chamber (5) for thermal treatment of organic material, combustion chamber comprising combustion apparatus (7) for heating combustion chamber, conveyor member (3) for conveying organic material during thermal treatment of organic material, feeding member (2) for receiving organic material and for feeding organic material to conveyor member, and removal member (4) for removing the thermally treated organic material from the conveyor member (3).    USE - Apparatus for thermally treating organic material to separate carbon from organic material used for producing biocarbon.    ADVANTAGE - The apparatus controls the amount of organic material for maximizing the separation of carbon from organic material.    DETAILED DESCRIPTION - Organic material treatment apparatus (1) comprises combustion chamber (5) for thermal treatment of organic material, combustion chamber comprising combustion apparatus (7) for heating combustion chamber, conveyor member (3) for conveying organic material during thermal treatment of organic material, feeding member (2) for receiving organic material and for feeding organic material to conveyor member, and removal member (4) for removing the thermally treated organic material from the conveyor member (3). A pipeline (8) is arranged outside of the combustion chamber for conveying pyrolysis gas coming through conveyor member and from the conveyor member through pipeline to the combustion apparatus such that the pyrolysis gas cools down and is burned in the combustion apparatus for creating heat inside the combustion chamber. An INDEPENDENT CLAIM is included for a method for using the apparatus.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the organic material treatment apparatus.
