ABSTRACT A summary is presented of a long teaching experiment to incorporate principles of process design in a chemical engineering science course. Students are assigned real world dryer design problems following a series of lectures clarifying the basic terminology, psychrometry and principles of drying. Selected references relevant to specific dryer design problems are also provided. The instructor and teaching assistants act as consultants to the design groups consisting of up to six students. This paper will refer to authors' recent experiences with this assignment using design of spouted bed dryers for grains as illustration.
