Abstract: A spray drying apparatus has a spray drying chamber; a liquid feed atomizer; a drying gas disperser; a perforated bottom; and a plenum chamber with an outlet below the perforated bottom. At least one guide plate is provided in the plenum chamber to direct gas, which is passing through the perforated bottom into the plenum chamber, towards the bottom of the plenum chamber. The guide plates have lower edges extending on average down to at least half-way between the perforated bottom of the spray drying chamber and the bottom of the plenum chamber.
