Rotary Atomizers are used in Spray Drying for atomizing the feed into fine droplets. In Rotary Atomizers, the kinetic energy of wheel rotation is used for atomization of the liquid.
Droplet size of atomized liquid depends upon liquid properties, disc speed, disc configuration etc. Bulk density is also one of the critical product requirement of spray dried products. The desired results can be achieved by using different Atomizer wheel configurations and optimizing atomizer speed, optimizing relevant feed properties
