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.
