Developing Adaptive Ultrasonic Drying Technology > <

Overview

The current ultrasonic drying system relies on generic transducers whose operating frequencies are not optimized for agri-food or pulp-and-paper materials, resulting in inefficient water removal. As samples dry and their acoustic impedance shifts dramatically from water to air, this mismatch further reduces power transfer and overall drying performance. Our project will implement a closed-loop feedback control system that continuously adjusts transducer operation—using real-time vibration and power measurements—to maintain impedance matching and intensify the drying process.
