Spray drying is a continuous process used to manufacture free-flowing dry powders from a liquid feedstock. The liquid feedstock is atomized into a heated air stream where the droplets rapidly dry to form individual particles. The resulting product is a free-flowing powder. Particle size, morphology and moisture content can be controlled by
Spray drying is the most used encapsulation method because of its relatively low cost and equipment availability (Gharsallaoui et al., 2007); compared to freeze-drying, spray-drying is 30 to 50

SPRAY DRYERS AND SPRAY DRYING TECHNOLOGY What is a Spray Dryer? A spray dryer, as the name implies, is a device for drying, utilizing a spray.. A spray dryer mixes a heated gas with an atomized (sprayed) liquid stream within a vessel (drying chamber) to accomplish evaporation and produce a free flowing dry powder with a controlled average particle size
A spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporized. Solids form as
Drum drying: in drum drying, the heated surface is the envelope of a rotating horizontal metal cylinder. The cylinder is heated by steam condensing inside, at a pressure in the range of 200 to 500 kPa bringing the temperature of the cylinder wall to 120–155 C.The wet material is applied on the drum surface as a relatively thin layer by a variety of different methods to be described later
Column dryers consist of tall, vertical vessels often with baffles to cascade the material. Powders or bulk materials are fed down through the column and heated by contact with baffles or drying air. Disc dryers are drum-shaped units that are filled with a series heated discs. Disc motion or airflow is used to move powders or bulk material

Drum Drying also known as Roll Drying is a continuous process that creates dry powders and flakes from a liquid feedstock. The liquid feed is sprayed onto or in between two rotating drums. The drums are heated internally with steam to increase the surface temperature. As the material is sprayed onto the drums, it sticks and dries to the surface
The disadvantages of drum drying are the following:. Some products may not form a good film on the drum surface and are not suitable for drum drying.. Some products, especially those with high sugar content, may not be easily scrapped off from the drum.. Relatively low throughput compared to spray drying.. High cost of changing drum surface

Pure β-carotene was encapsulated in 25 Dextrose Equivalent maltodextrin by three drying processes (spray, freeze and drum). Stability was studied at 11% and 32% RH and 25 C, 35 C and 45 C
Product temperatures in freeze drying are generally below 0 C in primary drying and 20-30 C during secondary drying, whereas product temperatures in spray drying are regularly above 80 C. The direct impact of working with these higher (80 C) temperatures, will sometimes be an overall loss of sample quality post drying in terms of inherent
Feb 03, 2003 gkandy (Chemical) 3 Feb 03 00:19. In my view , drum dryers are used for large throughput of granulated products. Spray dryers on the other hand can be designed even to handle throughputs in the range of 0.5 - 1 MT / hr. Spray dryers produce fine powder ( spray dried milk powder, detergent powder , some fine chemicals etc. )
