NOVELTY - The device comprises: a mixer (1), which is filled with a raw material; crushing device for crushing the raw material; a collection device (3) for collecting and conveying the crushed raw material; a pelletizing plant (12), which is produced by the pellets pressed from the crushed raw material; a measuring device for detecting a moisture content of an uncrushed and/or crushed raw material; and control device (18) depending on the moisture content of a humidifying device and a drying device. The measuring device for detecting the moisture content comprises a sensor in or on the mixer.    USE - The device is useful for producing pellets made of biomass, and heating additional buildings.    ADVANTAGE - The device is capable of simply and economically producing pellets with high quality and strength.    DETAILED DESCRIPTION - The device comprises: a mixer (1), which is filled with a raw material; crushing device for crushing the raw material; a collection device (3) for collecting and conveying the crushed raw material; a pelletizing plant (12), which is produced by the pellets pressed from the crushed raw material; a measuring device for detecting a moisture content of an uncrushed and/or crushed raw material; and control device (18) depending on the moisture content of a humidifying device and a drying device. The measuring device for detecting the moisture content comprises a sensor in or on the mixer. The drying device comprises a blower for blowing of heated air or a heated air mixture in the mixer with the raw material. A rotatable agitator is arranged in the mixers, and comprises a hollow shaft by which the heated air or the air mixture is blown into the raw material. A cutting device for crushing the raw material is arranged in a bottom region of the mixer, which comprises a bottom side of an opening adjustable in a size. A metal cutter and a mineral separator are provided behind the mixer. The crushing device comprises a hammer mill. The crushed material is supported by the crushing device over a cyclone to the collecting device. The collecting device and the humidifying device for increasing the moisture content of the crushed material are provided. The agitator and the crushing device are driven by a motor (17) whose waste heat is used for heating the air or the air mixture of the drying device. A tube-shaped conveying device is moved behind the pelletizing plant in which a cooling blower flow is conducted. An INDEPENDENT CLAIM is included for a method for producing pellets made of biomass.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic view of a device for producing pellets made of biomass.
