The Spray Dryer involving the conversion of fluid into fine droplets and exposing them to a hot drying media, so as to achieve defined dry particulate matter is spray drying. It is a widely used continuous industrial process which involves particle formation from feed fluid which may be in the form of the solution, emulsion or pumpable suspension into either dry powder or granules.

Spray drying involves following steps.

• Spray dryers are primarily used for drying of solutions and slurries into powders. We has serviced the industry by offering plants for a variety of applications ranging from heat sensitive products like enzymes, blood, flavours, to regular products like plant and animal extracts, milk, food and pharmaceutical applications, dyes and chemicals, detergents, catalysts to heat resistant products like ceramics, inorganic salts, glass and metals etc.
• Depending on the end product requirement there is different designs like rotary atomizer, pressure nozzle tower or two-fluid nozzle type spray dryer.

Other Details

• We have pilot plant facilities for conducting trials for products and for development of new procedures of drying. These facilities are available to end users and research institutes at nominal charges for development applications at mutually agreed terms

Atomization:

• Conversion of the feed into fine droplets is achieved by either pumping the feed under high pressure through an orifice or by spraying through a high speed rotating the perforated disc. The former is known as Nozzle Atomization and is popularly used to produce coarse droplets resulting in large granular particles of dried products. The latter is known as Rotary Disc Atomization and produces fine droplets resulting in fine powder particles of dried products.

Hot Air Mixing:
Air, which is, normally the drying media used, is heated to a predefined temperature depending upon the characteristics of the feed fluid and dried product either an indirect hot air generator or a direct hot air generator.

This hot air is brought in contact with the spray droplets in one of the following ways through the air distributor:

• Co-current-Air and particles move in the same direction.
• Counter-current-air and particles move in the opposite direction.
• Mixed flow - particles are subjected to co-current and counter-current phase.
• The thermal energy of the hot air is used for evaporation and the cooled air pneumatically conveys the dried particles in the system. The contact time of the hot air and the spray droplets is only a few seconds, during which drying is achieved and the air temperature drops instantaneously. The dried particle never reaches the drying air temperature. This enables efficient drying of heat sensitive materials without thermal decomposition.

Powder Separation:

• The dried powder is discharged continuously from the bottom of the drying chamber through the rotary valve and the air containing fines is taken to either a cyclone separator or passed through a textile fabric in a bag filter to recover the fines. The air is further scrubbed in a high-efficiency venturi scrubber before being exhausted out to the atmosphere.
• Special powder handling systems are used for industrial applications to either cool the dried powder or toe pneumatically convey the same to a product silo. These systems are tailor designed to suit the specific requirements and layouts. Spray dryer is an ideal choice as it offers defined end product characteristics in terms of particle size, moisture content, bulk density and particle shape.

Depending upon the process conditions, the type of evaporator is selected. Many times, the combination of stages is required or Hybrid evaporators are designed based on the process progress. Steam is normally the heating media, however, thermic fluid and other sources are also used. Waste heat recovery heat exchangers can also be offered.

Applications:

• Effluent concentrate before incineration
• Weak liquid low-temperature concentration
• Dilute Caustic lye solution concentration
• Herbal extract concentration
• Fruit juice concentration
