New technology accelerates drying of renewable cellulose nanocrystals

Researchers at the University of Illinois Urbana-Champaign and Purdue University has introduced a novel multi-frequency ultrasonic drying technology that enhances efficiency and sustainability in the production of cellulose nanocrystals (CNCs). This method not only accelerates the drying process but also reduces energy consumption compared to traditional drying techniques such as hot air, spray, and freeze drying.
