The influence of ultrasound on convective drying of potato was analyzed. According to
research, ultrasound usage improves potato quality. Results from rehydration show
that the structure of biomaterial dried with ultrasound is characterized by minor
changes. From the viewpoint of its application in industry, ultrasound significantly
reduces the time of the process, from about five hours to three hours. This makes it
possible to reduce energy consumption and total costs of the process, which is crucial,
because drying is one of the most energy-intensive process in food industry
