Spray dryers consists of a large
cylindrical & usually vertical chamber. In to which material to be dried
is fed in the form of small droplets. And hot air is fed to supply the heat
necessary to complete evaporation of liquid.
Spray drying process is applicable to a wide range of products and
industries.
Shachi handles the project ranging from laboratory size to large industrial
spray dryer processing lines and plants.
Design Consideration
Co-current type : Feed and hot air is from same side. Feed is from rotary
atomiser and nozzle.
Counter current : Feed is from top side and hot air from bottom side. Feed
is from from rotary atomiser and nozzle.
Co- counter type : Feed is from bottom side and hot air from top (Fountain)
side. Feed atomisation is through pressure nozzle or two fluid nozzle.
