INTRODUCTION
Â
A spray dryer is a complex instrument with different component. In most developed countries the presence of sophisticated spray dryer enhance the production of various plant which are in demand by developing countries.
Spray dryers are used to make homogenous powered substance whose particles are usually spherical in shape and approximately 10-140 micros. A spray dryer is used in chemical and foods processing to manufacture dried egges powdered milk, animals feed, cake mixes citrus juices, coffes cornyrup, cream, cramers, fish concentrate, infant formulas, potatoes shortening, starch derivatives, tea, tomato, pure, yeast and yogurt.
The spray drying process being as preheated solution is pumped to the atomizer. The atomizen increase the surface area of the solution by creating a fine mist. The mist is sprayed into a chamber of air heated to a temperature above the vapourizalion temperature of the solutions solvent. As the mist contacts the hot air, the sovent (typically water) vapourizes.
