Sonic drying applications in agriculture
     In agriculture, the acoustic field of technical aids drying process, to accelerate the diffusion of substances to promote drying and dehydration. Study suggests. Acoustic irradiation fluid and the solid surface can be reduced in the boundary layer, to improve the concentration gradient and to increase the diffusion coefficient of substances. Out of this, ultrasonic irradiation can improve the "constant phase" of the drying speed, and to "constant phase" extension. Thereby improve the drying efficiency of dry machining. And high-speed gas drying, ultrasonic drying not only reduces the material due to high temperature caused by the possibility of oxidation or degradation. But also to avoid being blown off or damaged raw materials and other issues. High-intensity ultrasound technology for the processing of dehydrated vegetables showed that the new high-intensity ultrasound technology can significantly shorten the drying time, easy to reach a final moisture content of the requirements.
