The Spray Dryer Apparatus demonstrates the drying process where liquid feed is atomized into hot air to produce dry powder. It enables the study of parameters such as air temperature, feed rate, and particle size. The setup includes an air heater, atomizer, drying chamber, and control instruments. Students can analyze moisture removal and drying efficiency. Suitable for engineering colleges, polytechnic institutes, and ITIs, this durable unit simulates real industrial drying systems safely and efficiently.
