Researchers developed a new drying technique for cellulose nanofibers that uses counter-rotating vortices (“mini tornadoes”) of heated compressed air to rapidly dehydrate a wet cellulose slurry. The innovation of producing these mini tornadoes to dry cellulose nanofibers is more energy efficient, effective and scalable than the current freeze and spray drying methods.
