This research project aims to address the challenges faced by the vacuum freeze-drying industry, such as high operational costs and prolonged drying times. The focus is on the application of direct ultrasound in Atmospheric Freeze Drying (AFD) to enhance water diffusivity and improve drying efficiency. The research will involve modelling and fabricating a prototype of an Ultrasound-assisted AFD system. The effectiveness of this system will be assessed through the drying kinetics analysis and physical, and chemical characterization of apples and eggplants.
