spray dryer heat calculation

Evaporation is defined as the difference between inlet and outlet temperature, or ΔT, in the drying air. The larger the ΔT, the greater the capacity of the spray dryer. The goal in optimizing a spray dryer’s capacity is to increase ΔT by raising the inlet temperature or lowering the outlet temperature. What is the optimal outlet temperature?
