Abstract: A method for refining pellets, in which, in a first step, pellets that have been pressed from a biomass are provided. A heat treatment is carried out, involving heating the pellets to a temperature between 210° C. and 390° C. The heat treatment takes a period of time of between 1 minute and 30 minutes. Also described is a device that is suitable for carrying out the method. The pellets treated in this way are water-repellent and so can be stored outdoors.

Abstract: The method for disintegration of materials containing lignocellulose to fibers is characterized in that roller pressure is applied to the material containing lignocellulose in a flat die pellet mill by pinch rollers which can have an offset from the die of several millimeters, said pressure being applicable over a wide area, and the material being in a mixture with fiber-improving agents and moist on the surface, whereby the fiber improving agents, supported by the high moisture in the pore interiors, enter far into the interior of the fiber material and react spontaneously or with a delay, wherein finally the disintegrated and refined material is pressed through the bores of the flat die.
