Abstract This scientific report discusses the thermal dehydration process. Drying is a ubiquitous operation found in almost all industrial sectors, ranging from agriculture to pharmaceuticals. It is arguably the oldest, most common, most diverse, and most energy-intensive unit operation. Drying technology is an amalgamation of transport phenomena and material science as it deals not only with the removal of a liquid to produce a solid product but also with the extent to which the dry product meets the necessary quality criteria. This thesis discusses the phenomenal growth in drying literature as well as in new drying hardware. It is now virtually impossible for academic and industry personnel to keep abreast of the developments and evaluate them logically. Therefore, the main objective of this thesis is to provide an evaluative overview of the new and emerging technologies in drying, which are not readily accessible through conventional literature. We have attempted to provide a glimpse of the developments that have taken place in the past two decades and the directions toward which we see these technologies heading. We also discusses the energy issue in the industrial dryers with solutions to increase the dryer efficiency and also a recommendation for using the renewable energy like the solar energy. |
