Excellent En-Fab Incorporation is a trusted Manufacturer and Exporter of Spray Dryer in Bangladesh.
We are based in Ahmedabad, Gujarat, India.
A Spray Dryer is a highly efficient industrial drying system used to convert liquid or slurry into dry powder form by rapidly drying with hot gas.
Industries widely use spray dryers in food, chemical, pharmaceutical, and process applications because they produce uniform, free-flowing powder with controlled particle size.
Work (Function of Spray Dryer)
The spray dryer works by transforming liquid feed into dry powder in a single continuous process:
- The system pumps liquid feed into the drying chamber.
- A nozzle or rotary atomizer atomizes the liquid into fine droplets.
- The system simultaneously introduces hot air into the chamber.
- Hot air instantly evaporates moisture from the droplets.
- The system collects dry powder from the bottom or cyclone separator.
Components of Spray Dryer
A standard spray dryer consists of the following key components:
- Feed Tank – Holds the liquid solution or slurry
- Pump System – Controls and supplies feed into the chamber
- Atomizer / Nozzle – Converts liquid into fine droplets
- Drying Chamber – Main area where drying occurs
- Air Heater System – Provides hot drying air
- Cyclone Separator – Collects fine powder particles
- Bag Filter / Dust Collector – Ensures clean air exhaust
- Control Panel – Manages temperature, airflow, and feed rate
Working Principle
The spray dryer operates on the principle of atomization and rapid moisture evaporation:
- Liquid feed is atomized into a mist of fine droplets
- Hot air is introduced in co-current or counter-current flow
- Large surface area of droplets enables instant evaporation
- Moisture is removed within seconds
- Dry powder is separated and collected efficiently
