  • Publication number: 20110154684
    Abstract: The present invention relates to a method and an apparatus for the manufacture of torreficated lignocellulosic material. Finely divided lignocellulosic material is exposed in running order for drying, heating to at least 200° C. in the absence of oxygen (the torrefication process itself) and cooling to a temperature preferably being below 130° C. The drying device (3) and the torrefication chamber (4) are jacketed, which allow performing of the drying as well as the torrefication with steam at over-pressure using indirect heating with the result that the heating medium is not contaminated during its cycle of operation. The heating steam is withdrawn in a steam turbine being part of a power/heating plant or a steam boiler and leaves the system preferably in the form of condensate water (32).
