NOVELTY - The method for drying biomass (10) such as wood chips and fermenting residues of biogas plant, comprises supplying the mass to be dried into a drying container via a lockable inlet (1), circulating and mixing the mass by a circulating drag chain (2) in a continuous or interval manner, and heating the mass by supplying dry air through a radial ventilator (3). Water is bound over an air circulation for air saturation. A uniform air pressure relationship is created with a base and spatial ventilation (4, 5). A drying fiber is added to the drying process during the air flow.    USE - Method for drying biomass such as wood chips, fermenting residues of biogas plant, paper slurries, clarifying slurries, industrial waste of mineral or organic source and other mud-like masses (claimed).    ADVANTAGE - The method is capable of economically drying biomass with a dry content of 80%.    DETAILED DESCRIPTION - The method for drying biomass (10) such as wood chips and fermenting residues of biogas plant, comprises supplying the mass to be dried into a drying container via a lockable inlet (1), circulating and mixing the mass by a circulating drag chain (2) in a continuous or interval manner, and heating the mass by supplying dry air through a radial ventilator (3). Water is bound over an air circulation for air saturation. A uniform air pressure relationship is created with a base and spatial ventilation (4, 5). A drying fiber is added to the drying process during the air flow. The emptying of the drying container takes place after switching off the radial ventilator over an outlet (7) by the drag chain. The heat air is saturated with 40-120 degrees C when flowing through the drying mass through the water absorption. A pre- and a final drying process take place as two-phase drying process with two drying containers. A vapor-air return is insertable and the drying system is adapted by the size of the drying containers. An INDEPENDENT CLAIM is included for a device for drying biomass.
