As it follows from the presented data, application of ultrasonic assisted
osmosis enabled to shorten the drying time by about 40 min, both
in stable and in intermittent conditions. However, the combination
of osmotic pretreatment with ultrasounds and convective intermittent drying shortened the drying time more than an hour (i.e.
about 70 min), compared to continuous air drying preceded by
assisted UD osmosis.
