Spray dryer heat calculation

Elevating the temperature as high as the product allows without degradation yields extra capacity from the spray dryer by acquiring heat from a source other than the main air heater Finally, using the highest concentrations of feed solids yields greater capacity This topic, however, is beyond the scope of the spray dryer itself
