Abstract: A method for drying nanofibrillated polysaccharide to obtain a substantially dry nanofibrillated polysaccharide product, comprising the following steps: (i) providing an aqueous suspension of nanofibrillated polysaccharide; (ii) increasing the solid content of said suspension, thereby forming a high solid content microfibrillated cellulose suspension; and (iii) drying said high solid content microfibrillated cellulose suspension, through a simultaneous heating and mixing operation.

Abstract: The invention relates to a process for treating cellulose fibres which process comprises the steps of providing a slurry comprising cellulose fibers, adding anionic polyacrylamide (A-PAM) with high molar mass to the slurry in a first step and subjecting the slurry comprising fibers and A-PAM to a mechanical treatment in a second step thereby forming a composition comprising microfibrillated cellulose. The invention further relates to a composition produced according to the process.
