Microwave Drying of Food and Agricultural Materials

2012-1-24Microwave drying is based on a unique volumetric heating mode facilitated by electromagnetic radiation at 915 or 2 450 MHz The responses of a lossy food product to dielectric heating result in rapid energy coupling into the moisture and lead to fast heating and drying A significant reduction in drying time in microwave drying is often accompanied by an improvement in product
