Drying Solids: Theory and Types of Dryers

This lecture covers the theory and practice of drying solids, focusing on the removal of solvent to obtain a finished product. It discusses factors influencing drying, types of dryers, and the characteristics of different drying methods. The presentation delves into the mechanisms of heat and material transfer during drying, as well as the influence of physico-chemical properties on the process. Various types of industrial dryers are explored, including freeze dryers, fluidized bed dryers, and drum dryers. The lecture also addresses the criteria for selecting a dryer based on product constraints, energy efficiency, and manufacturing process requirements.
