Drying technology is very old in human history and is not only related to the food processing industry, but also extends to a broad range of applications in the chemical, biochemical, pharmaceutical, and agricultural sectors. The drying of various materials at different conditions in a wide variety of industrial and technological applications is a necessary step either to obtain products that serve our daily needs or to facilitate and enhance some of the chemical reactions conducted in many engineering processes or make them environmentally safe. Drying processes consume large amounts of energy, and any improvement in existing dryer design and reduction in cost will be immensely beneficial for the industry. Drying is inherently a cross- and multidisciplinary area because it requires optimal fusion of transport phenomena and materials science because the objective of drying is not only to supply heat and remove moisture from the material but also to produce a dehydrated product of specific quality.

In order to improve the drying efficiency, lower the drying cost, and get the high quality product, the researchers and engineers have done all kinds of study. This special issue is seeking papers related to the study of the engineering applications devoted to the drying technology. Potential topics include, but are not limited to:

• Theory and its application
• Modeling and simulation
• Advanced drying technology
• Green drying technology
• Control and optimization
• Dewatering
• Energy and environmental implication
