Drying of moist porous media, such as pulp and paper, is an energy-intensive process. Traditional drying technologies have disadvantages including high energy consumption, thermal degradation of the samples, and high capital cost. In the current study, a novel drying technology using ultrasound mechanism for paper drying is introduced. Specifically, the sample weight and surface temperature have been monitored during the experiments using piezoelectric transducers. The experimental results show a significant impact of the ultrasound on the surface temperature and the drying rate. This research is the foundation of the future studies for providing a fundamental understanding of ultrasound drying technique and its potentials for reducing energy consumption and CO2 emission, globally.
