Ultrasound in wet biological materials subjected to drying
Stefan Jan Kowalski

T
he aim of this article is to present the effect of external action of air-borne ultrasound (US) upon biological wet materials
subjected to drying. The study allows determining the drying effectiveness of such products like fruits and vegetables
by convective drying with ultrasound enhancement. The vibration and heating effects induced by power ultrasound are
considered. The mathematical model of drying is developed and validated experimentally using the data obtained from the
experimental tests carried out on the hybrid dryer equipped with ultrasonic generator. The obtained results proved that the
vibration effect induced by ultrasound has a great impact on the acceleration of mass transfer without significant elevation of
product temperature and thus on the drying efficiency with respect to energy utilization and the quality of dried products like
fruits and vegetables.
