Applications of Spray Dryer:
1. Drying liquid or slurry materials into dry powder 
2. Atomizing type: centrifugal atomizer 
3. Evaporation capacity: 3-1000 kg/h 
4. Heat source: steam, electricity, oil/gas/coal fired hot air generator 


Working principle of spray dryer :
Working principle: Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals.
Liquid material is pumped into the top installed rotary disc atomizer by mono pump and atomized into fine droplets inside the drying chamber. Heated and filtered hot air will be blown into the air distributor at the same time. The evenly and swirly distributed hot air completely contacts with the droplets for heat transfer. In several seconds, the droplets will be dried into powder and sucked out into the cyclone for discharging via exhaust fan.


Application: LPG series spray dryer has been widely used in pharmaceutical, chemical and foodstuff industry for drying liquid material into fine powder.

Note:For the water evaporation capacity, material property,the inlet and outlet tempratures,please refer the following diagram for reference.
1.Fine droplets are dried in the drying camber by supplying hot air through the inlet.
2.The surface of the liquid drop is dried immediately to form a tough shell.
3.Further the liquid inside must escape by diffusing through the shell at a particular rate.
4.At the same time heat transfer from outside to inside takes place at a rate greater than liquid diffusion rate.
5.As a result heat inside mounts up which allows the liquid to evaporates at faster rate.
6.This tendency of a liquid leadsto rise in the internal pressure which causes the droplets to swell.
7.The shells thickness decreases where as permeability for vapour increases.
8.If the shell is neither elastic nor permeable it ruputur and the internal pressure escapes.
9.The temperature of the air is adjusted in such a way that the droplets should be compeletly dried before reaching the walls of the drying chamber.
10.The products should not be over heated at the same time.

Technical advantages of spray dryer :
1)  Particle size control: The dry particle size can be easily controlled by atomization of the liquid feed and the design of the hot gas inlet. This spray dryer can typically produce between 30 to 500 micron average particle size, in a bell shaped distribution.
2)  The evaporative cooling of product: The heat and mass transfer during drying occurs in the air and vapor films surrounding the droplet. This protective envelope of vapor keeps the particle at the saturation temperature. As long as the particle does not become "bone-dry", evaporation is still taking place and the temperature of the solids will not approach the dryer outlet temperature.
3) Short residence time: The surface area produced by atomization of the liquid feed enables a short gas residence time, ranging from 3-10 seconds depending upon the application, which permits spray drying without thermal degradation.
4) Flow properties of dry product: The shape of most spray dried particles is spherical, which provides for fluid-like flow properties.  This makes many downstream operations, such as packaging, pressing, filtering, and handling easier and less costly.
5) Size design of drying chamber: The size of drying chamber is specially designed to prevent droplets sticking to the inner wall, dried powder accumulating on the cone part and guarantee enough residence time.

1.Spray dryer can be used for drying of ny substances both in solution or in suspension.
2.Spray dryer are very useful for the drying of thermolabile substances.
3.Citric acid, borax, sodium phosphate, hexamine, gelatine and extracts are dried by a spray dryer.
4.The suspensions of starch, barium sulphate and calcium phosphate are also dried by the spray dryer.
5.Milk, soap and detergents too are dried by a spray dryer.
