Abstract :
Ultrasound can enhance mass transfer rate inside and outside materials during dehydration, so it´s often used to strengthen osmotic dehydration. Yet osmotic dehydration can´t obtain dry products and is usually applied as pretreatment for other drying process. Ultrasonic osmotic dehydration combined hot-air drying process is investigated in this paper. The influences of operation parameters such as time, ultrasound power, solution concentration and system temperature on water removal ratio are discussed. The effects of ultrasonic osmosis on total dehydration time of drying carrot slices are also studied.
