Spray dryer is a drying machine used to process solutions, suspensions, or materials in a slurry state.
Spray dryers are commonly used in the food, pharmaceutical, and chemical industries to produce powders from a variety of materials, including milk, coffee, antibiotics, and detergents. They are known for their efficiency, speed, and ability to produce powders with a consistent particle size distribution.
ADVANTAGES OF SPRAY DRYING
- 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.
