Effectiveness of using acoustic oscillations of ultrasonic frequency on the process of removing moisture from porous material

The article presents the results of a study ultrasonic drying process which is promising way to intensify moisture removal at low temperatures. An experimental stand was developed for research. an dryer with automatic maintenance set temperature. A flexural-oscillating disk radiator used as source action. conducted studies have shown that changing speed agent from 0.1 m/s 0.2 during convective can slightly reduce time 100 minutes 90 (10%). Change allows reducing by 10 minutes, 80 70 Due exposure m/s, reduced minutes. At temperature 400C, 25% due (from 160 120 minutes).
