Abstract

Drying wet particulate solids is part science, part craft. Striking the right balance between the nature of the product, equipment design, and operating conditions is essential, not just to maximise the yield in removing water, but to preserve product quality, and keep the whole process running smoothly in harmony with upstream and downstream operations. Air drying, which uses heated air to dry particles, is a critical operation in many process industries, including food, pharmaceuticals, chemicals, and minerals. Although it is widely used, it still presents challenges, especially when handling powders that tend to be sticky, cohesive, or poor-flowing.
