For hot air drying, the temperature transfers from the surface of the material to the center, and the direction of moisture is opposite, that is to say, the transfer direction of moisture gradient and the transfer direction of temperature gradient are opposite. So the temperature gradient will be an obstacle to the diffusion of moisture along the moisture gradient

airjet impingement andhot air assisted radio frequency

Dec 01, 2019· Air jet impingement (AJI) was applied as the 1st stage drying method for fresh samples, and hot air-assisted radio frequency (HA-RF) was used for the 2nd drying stage to reduce the moisture content of semi-dried samples to the target level (<15 g/100 g w.b.)
