Industrial Spray Dryer

Spray Dryer technology is widely used in the industry for converting liquid solutions/ suspensions/ slurry /emulsions to powder, granules or agglomerates.

The advantages of spray drying are consistent product quality, with better control on product parameters like product moisture, bulk density, particle size, dispersion, flow ability etc.

AVM offers Customized Spray Drying Systems with variety of Configurations.

Air Flow Pattern Configurations :

• Co- current.
• Counter-current.
• Mixed flow.

Combination of Systems Configurations :

• Two Stage Spray Dryer : Spray dryer followed by fluid bed dryer for drying products which require longer residence time & product conditioning post drying.
• Three Stage Spray Dryer : Spray dryer with Internal fluid bed followed by external fluid bed dryer for producing dust free agglomerates.

Liquid Atomizer Configurations :

• Single Fluid Nozzle Atomizers : The liquid feed is atomized into spray droplets by using pressure energy.
• Two Fluid Nozzle Atomizers : The liquid feed is atomized into spray droplets by using energy of secondary fluid like Compressed Air, Nitrogen etc.
