Despite all these studies, no commercial scale installation of the ultrasound drying technology has been developed to date
(Kowalski and Pawlowski, 2015; Soria and Villamiel, 2010). This is due to some technological challenges in achieving an efficient
transmission of acoustic energy and the practical difficulties in adapting the technology at an industrial scale. Hence, there is still
considerable scope for significant improvements in bringing the application of ultrasound technology closer to industrial drying
operations. Together with future advancements in ultrasonic designs, further research efforts in understanding the fundamental
mechanisms for effective ultrasound application will provide the basis to build upon the development of this technology for adoption
in industrial drying practices.
