Abstract

A method of producing dried cellulose nanofibrils includes atomizing an aqueous suspension of cellulose nanofibrils and introducing the atomized aqueous suspension into a drying chamber of a drying apparatus. The aqueous suspension is then dried, thereby forming substantially non-agglomerated dried cellulose nanofibrils.
