Solids Processing and Particle Technology: Principles of Drying - Theory and Practice

AIChE Webinar
Originally delivered Sep 7, 2011

Drying is a commonly used unit operation in the process industry and is responsible for a significant amount of energy usage. Yet drying often results in both process inefficiencies, usually manifest as lack of production rate, or poor product attributes such as out of specification moisture and particle properties. These properties may include taste, texture, color, etc.

This webinar outlines the basics of drying and reviews the characteristics of the most commonly used dryers.The concept of generation and use of drying data for scale-up is examined in detail for both convective and contact dryers with particular emphasis on the use of the single particle drying curve. Lastly, since dryers usually operate as part of a larger system, the impact and selection of the ancillary equipment is discussed and its role in design of a successfully drying system.
