Spray Dryer

Spray dryers are mostly used for powder formation while a slurry or an undersaturated liquid is passed through hot air. Spray dryers are used to achieve a certain particle size distribution and for handling temperature sensitive materials during powder formation. With this model, the dryer dimensions and drying time can be calculated. Spray dryers have applications in industries such as food, pharmaceutical, ceramics and paint pigments.

The existing CHEMCAD model for dryer unit op only performs mass and energy balances.
