The invention relates to a device for drying solid biomass, comprising a plurality of cyclones (1A to 1E) arranged in series, each cyclone comprising a lower conical part. A first cyclone (1A) comprises a hot gas supply line (2) and a gas outlet line (3A), the other cyclones (1B to 1E) comprise a gas inlet line (4B to 4E) and a gas outlet line (3B to 3E), and each cyclone comprises a lower vertical line (5A to 5E) for the flow of the solids towards the top of the adjacent cyclone. According to the invention, the hot gas supply line (2) goes into the top of the upper cyclone (1A) and the gas inlet line (4B to 4E) of the other cyclones also goes into the top of the corresponding cyclone. |
