摘要： 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 The heating steam is withdrawn in a steam turbine being part of a power/heating plant or a steam boiler and leaves the system preferably in the form of condensate water (32). The input (2) and the output (5) of the lignocellulosic material from the drying device (3) take place gastight and the same accounts for the torrefication chamber (4), which however in its output end can be openly connected to a gastight cooling device (7). During the drying of the lignocellulosic material evaporated gases, mainly water vapor, is fed to a condenser (12). Reactor gas formed during the torrefication process is fed (24) to a combustion oven (23) supplied with combustion air (22).
