摘要

Method and device for improving mass transfer processes at low temperature by using high intensity ultrasound. The present invention relates to a method to accelerate and improve the transfer of at least one solvent, entrapped in a solid matrix or semisolid, a gaseous medium at an absolute pressure less than 0.5 atm and at a temperature exceeding 15 ° C characterized by comprising the application of an ultrasonic field high intensity equal or higher than 150 dB. It is also object of the invention the device for carrying out said method and its use in the food, chemical, cosmetic and / or pharmaceutical field.
