The present invention relates to a process for liquefaction and
saccharification of polysaccharide containing biomasses, having a
relatively high dry matter content. The present invention combines
enzymatic hydrolysis with a type of mixing relying on the principle of
gravity ensuring that the biomasses are subjected to mechanical forces,
primarily shear and tear forces. Furthermore, the present invention
relates to the further utilisation of such processed biomasses, e.g. for
subsequent fermentation into bio-ethanol, bio-gas, specialty
carbohydrates for food and fees as well as carbon feedstock for
processing into plastics and chemicals.
