Spray Dryer
Spray driers are used for converting slurrier into fine droplets by spraying the material into a stream of hot gases. The slurry is pumped through an orifice at high pressure or through a high speed perforated rotating disc. The droplets are brought into contact with hot air and are converted to dry powder or granules used for drying of Detergents, Polymers, Dyestuff, Food, Ceramic, Chemicals etc.

Spray dryer consists of a large cylindrical & usually vertical chamber in which material to be dried is, in the form of small droplets and fed a large volume of hot air sufficient to supply the heat, necessary to complete evaporation of liquid.
Spray drying process is applicable to a wide range of products and industries.
SF ENGG WORKS handles the project ranging from laboratory size to large industrial spray dryer processing lines an plants.

Design Consideration
Co-current type : Feed and hot air enters 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 rotary atomiser and nozzle
Co counter type : Feed is from bottom side and hot air is from top (Fountain) side. Feed atomisation is through pressure nozzle or two fluid nozzles. |
