Spray drying produces engineered powders in one step from liquid feeds with applications across numerous industries. One major problem in spray drying is potential deposition of particles on the internal wall of the spray chamber. Such a problem can be severe if the operating parameters for a particular new feed is not known or if modifications are to be made in existing operations. The first part of this book introduces a rapid systematic approach to optimize the operation of a spray dryer. A new concept is introduced to reduce deposition via dryer wall surface energy...
