Apparatus for Ultrasonic Drying of Disperse Materials

The article is devoted to describing of construction and determining of main technological parameters of apparatus for drying of disperse materials. It is presented the mathematic model describing the processes of transferring of heat and mass from surface of disperse particles transported by air flow. The model allows to calculate the main technological parameters developed drying apparatus. Influence of ultrasonic vibrations on efficiency of heat and mass transferring from surface of disperse particles is taken into consideration for the first time. Model calculations of drying apparatus for productivity equaled to 1 t/h in dry matter (by example of sawdust) are provided.
