Abstract: A method of controlling a spray dryer apparatus having a spray dryer chamber (1), an air inlet (2), an inlet air control system (11) including a fan (13) and an air heater (14), a feed inlet (3), and an exhaust air outlet (4), comprising determining a content (Y) of moisture of inlet air, determining an inlet air temperature set value (Tinlet) in dependence of the inlet air moisture content (Y), determining an inlet air temperature measured value of inlet air between the air heater (14) and the spray dryer chamber (1), and regulating the inlet air temperature in dependence of the inlet air temperature set value and the inlet air temperature measured value, and determining an outlet air temperature of the exhaust air and regulating an inlet air flow rate in dependence of the outlet air temperature.
