1. A process for treating polysaccharide containing biomasses characterized by subjecting a polysaccharide containing biomass having a final dry matter content of above 20% and comprising lignocellulosic biomass to:
a) enzymatic hydrolysis using at least one cellulase enzyme, and
b) mixing by a free fall type mixing that provides mechanical degradation of the biomass during hydrolysis,
wherein the mixed biomass is liquefied to a liquid without any or with only a few remaining large fibres and particles in the process.
