Microwave drying (Figure 10) is extensively used to dry food materials due to the high drying rate and uniform drying (Nair et al., 2011). Microwave drying can also improve the quality of some food materials. Microwave drying can enhance the drying rate during falling rate period (final stage of drying). During falling rate period, conventional drying results in the shrinkage the samples and low surface moisture content. However, during microwave drying, vapors are generated in the interior of food materials due to volumetric heating. These vapors are forced to move outside due to the pressure gradient. Hence, microwave drying can prevent the shrinkage of food materials. In order to improve the drying efficiency and quality of dried product, microwave drying can be combined with other drying methods.
