Conversion of the feed into fine droplets achieved by spraying through a high speed rotating perforated disc is known as Rotary Disc Atomization and produces fine droplets resulting in fine powder particles of dried products. 

Conversion of the feed into fine droplets achieved by pumping the feed under high pressure through an orifice is known as Nozzle Atomization and is popularly used to produce coarse droplets resulting in large granular particles of dried products. 

Single stage spray dryers offer particle sizes of dried material from 50-250 microns. For producing large particles Fluidized Spray Dryers are employed. The atomization of the feed solution is done to produce large droplets and the drying in the first stage is done keeping the moisture content of the powder relatively high. The moist powder is dried in the integrated fluid bed system at the bottom of the drying chamber using hit air, and in the process, agglomeration of fines to larger particles takes place. The absolute fines are carried with the exhaust air leaving the drying chamber to be collected in the cyclone and further recalculated to the drying chamber. Tertiary drying systems comprise of employing additional external drying system to further increase the particle size. Shown in the layout is one of such system incorporating a fluidized spray dryer with vibratory fluid bed drier.

These are dryers used for drying the product in solvent base, by spraying the solution or slurries in a nitrogen atmosphere and recovering both the product and the solvent. The drying system can be equipped with fire detection, extinguishing and explosion suppressants. Such systems are ideal for handling solvents, heat sensitive products, prevent oxidation of dried product, and also provide aseptic condition.

A spin flash dryer produces powder from feed, which is viscous or gelatinous in nature, paste or filter cake. The two step process involves disintegration of the feed and drying of the disintegrated feed. Depending upon the nature of the feed material, conventional arm design could be used for crystalline, non-sticky material or Acmefil's specially engineered rotating spin design disintegrator could be used to handle sticky and gelatinous materials. 

Drying process is accomplished by contacting the powder with hot air travelling at high velocity. The heat is used for drying and the air pneumatically conveys the powder for separation in a cyclone or a bag filter. A product classifier ensures only dry powder leaving the drying chamber. 

SPRAY PYROLYSIS SYSTEMS is custom built drying system used for continuous transformation of liquid feed into a dried solid product by spraying the feed into a stream of hot drying air.

Spray Cooling is a process of conversion of molten mass into droplets which is exposed to cold air and thereby solidifying the liquid into defined particles size.
