Spray Drying
Spray drying is a process that turns a liquid or slurry into a dry powder by rapidly drying it with a hot gas.
The spray drying process involves the following steps
- Atomization: The liquid is dispersed into a controlled spray of droplets using a spray nozzle or atomizer.
- Drying: The spray is dried in the hot gas stream.
- Formation: The droplets form dry particles.
- Collection: The dry product is separated and collected from the drying gas.
Process of Spray Drying
Some advantages of spray drying include:
- Low operating costs: Spray drying is energy-efficient and has low operating costs.
- Fast processing: Spray drying is a fast process.
- High encapsulation efficiency: Spray drying has a high encapsulation efficiency.
- Encapsulated product stability: The encapsulated product is stable.
- Control over particle size: The size, shape, and morphology of the particles can be controlled.
