Enhancement of heat and mass transfer in drying systems for bio-economy and sustainable development

Drying techniques have been developed and improved over the course of human development since prehistoric times. Originally developed for the preservation and storage of food, drying techniques have been applied in many areas of industrial processes to achieve faster progress and development. Conventional and advanced drying techniques can be applied to achieve solutions for the numerous problems and challenges faced by humans now. In addition to the routine applications in daily life, drying techniques have been an integral part of bio-processing, food processing, thermo-chemical conversions, waste treatments, and so on. This review gives a brief overview of the developments in drying techniques that help in the progress of the bio-economy, thus achieving sustainable development goals for humanity.
