Drying (or dehydration) is one of the important unit operations in food manufacturing, mainly aimed at the preservation of foods by reducing the amount of moisture in the food matrix to levels that will slow down/inhibit microbial and enzymatic activities and the associated product quality deterioration (Sabarez, 2015). It involves the removal of water from a wet feedstock by inducing phase changes of water from solid or liquid into a vapor phase via the application of heat (except in the case of osmotic dehydration during which the water is removed without a change in phase by the diffusion of liquid water from solid foods to an osmotic solution through an osmotic pressure difference). Drying is (in most cases) an energy-intensive process, which usually leads to pronounced alterations in product quality attributes due to the exposure to long drying times at high temperatures. The process of drying food materials is extremely complex, involving coupled transient mechanisms of heat, mass, and momentum transfer processes accompanied by physical, chemical, and phase change transformations (Sabarez, 2014 and Sabarez, 2012).
