ABSTRACT
Drying is discussed in this chapter as a common and popular process technique in process engineering. Drying is applied in several types of industries for a diverse range of objectives. Quality enhancement, preservation, shelf-life improvement, size reduction, and waste recovery are among the vast range of drying targets. It is also considered an intensive energy-consuming process, mainly from the high latent heat of vaporization. Moist air is a mixture of gases that is a constant element of a typical drying process. In thermodynamics, a mixture of gas is addressed in separate chapters since the properties of components must be identified to have an engineering understanding of the mixture. The preliminary concepts to work out problems dealing with drying are provided for review. Then, the chapter covers a review of psychrometrics as a popular technique to solve the engineering properties of gas-vapor mixtures. Some general topics on drying methodologies are presented, and examples are solved for better understanding.
