Application of High-Power Ultrasound for Dehydration of Vegetables: Processes and Devices
9 páginas, 12 figuras.High-intensity ultrasound is a tool with a great potential for
vegetable dehydration. Airborne ultrasonic waves have been used
for drying materials in combination with hot air systems to obtain
adequate drying rates at lower temperatures. Nevertheless, the
extension of this technique has been limited because of practical
difficulties in the efficient generation of high-intensity ultrasound
in air. The implementation of a new technology of plate-transducer
power ultrasonic generators has opened up new possibilities in this
area. This article reviews the development and testing of an
ultrasonic technology for vegetable dehydration based on the
application of the new power ultrasound generators. Two
experimental procedures have been carried out by airborne
ultrasound and ultrasonic vibration in direct contact with the
vegetable.Peer reviewe
