2.1.2. Atomization. Atomization is a very important operation in spray drying process. It determines the distribution of droplet sizes in the resulting cloud and determines the energy required for atomization, the trajectory and velocity of particles leaving the atomizer forces the appropriate shape of the drying chamber. The droplet size …

Spray Dryers are designed for drying of slurries and liquids. Sprays Dryers can be configured in numerous ways from co-current to counter-current and the slurry or liquid can be introduced to the process via high pressure atomizing nozzles or high-speed wheel atomizers. Capacities range from 100 kg/hr to in excess of 30 tph.
