The Drum Dryer apparatus demonstrates continuous drying of liquids and slurries using a rotating heated drum. Students learn how temperature, drum speed, and feed rate affect drying efficiency. The setup includes a stainless-steel drum, feed arrangement, scraper, and control panel for operation. It enables measurement of drying rate, heat-transfer coefficient, and product moisture. Ideal for engineering colleges, polytechnic institutes, and ITIs, this trainer provides real-world understanding of industrial drying processes and heat-transfer applications.
