Experimental investigation of drying behaviour of raw wool in an ultrasound assisted low temperature convection dryer

Drying is a process which conventionally consists of the steps heating trying air then loading heated air with moisture by crossing it over wet matter and finally discharging the air to atmospher or reuse of air after condensation of water in drying air and possible to be increased its performance via some additional physical effects. When studies are examined, it was determined that the ultra sound supported waves have effects on drying process, which shorten the drying times and allow drying at lower temperatures. Currently, ultrasonic sound waves with a frequency level of over 20,000 hertz used in processes such as surface cleaning by immersion in liquid, pulverization of open-surface fluids; Detecting the effects of drying on the drying process by ultra-sound drying of the raw wool material and determining the drying efficiency increase provided by the ultrasound support will form the basis of this thesis.
