Automatic Control System for Spray Drier Pilot Plant

Spray drying consists of three process stages: • Atomization • Spray-air mixing and moisture evaporation • Product recovery Each stage is carried out according to the dryer design and operation and together with the physical and chemical properties of the feed determines the characteristics of the final product.

Control of Detergent Properties in a Spray Dryer Process

Spray drying is a process used to produce a dry powdered product, such as a detergent, from a liquid feed. The liquid feed is introduced into a spray dryer via an atomization device to produce a spray of droplets. These droplets are then dried by a hot air stream entering the spray dryer concurrently or counter currently to the spray direction.
