Spray drying process is very fast and efficient drying process and which allows a short time for evaporation to takes place and for this it is very essential that the feed can be adequately be atomized into a spray of droplets for successful spray drying. This causes fast drying of the droplets as evaporation occurs from the large surface area is generated by the atomizer.
The important factors in the atomization are viscosity, size and surface tension , shape and physical behavior of suspended components which determines how well the feed atomises.Advantages
- Highly viscous material can be handled.
- High solids can be handled resulting better economy.
- Large quantity of material can be handled.
- Different wheel types can be designed according to the different material characteristics.
