Preferred Label : Direct Heating, Dilute Solids Bed, Spray Drying;
NCIt definition : Heat transfer is accomplished by direct contact between a highly dispersed liquid
and hot gases. The feed liquid may be a solution, slurry, emulsion, gel or paste,
provided it is pumpable and capable of being atomized. The fluid is dispersed as fine
droplets into a moving stream of hot gases, where they evaporate rapidly before reaching
the wall of the drying chamber. The vaporized liquid is carried away by the drying
gases. The solids are fully expanded and so widely separated that they exert essentially
no influence on one another.;
