Spray Dryer for Drying, Coating

The droplets are small, giving a large surface area for heat and mass transfer so that evaporation is very rapid. It can be used for drying heat sensitive or oxidized materials without degradation. It can be designed for drying under sterile conditions. The dried powder will have a uniform particle size and shape. Because of good flow properties, the spray-dried powder can be easily compressed into the form of tablets. It is useful in the coating and encapsulation of both solids and liquids. Labor cost is low since the material is dried in a single operation with no handling.
