This is achieved, in terms of method, by means of the following steps: comminuting the grist by means of breaking it in beater impact mills (3) and/or corrugated rollers (16), screening the mixture of coarse and fine particles produced, separating the plant shells (fibers) and proteins by using water (5, 18), drying (6) the components, and pressing (8) the woody components into pellets as fuel for energy production.Type: ApplicationFiled: October 14, 2010Publication date: February 14, 2013Inventors: Erhard Bazak, Andreas Freiherr von Tautphoeus
