A dryer for drying a liquid feed (11, 11') into a powder (35) comprises a drying chamber (3) defined by a chamber wall (5) including a bottom wall portion (7), a feed inlet for receiving the liquid feed (11) and dispersing particulate feed (13) into the drying chamber (3), at least one air inlet (15) for entering drying air into the drying chamber (3) and at least one drying chamber outlet (17) for dried powder and/or spend drying air from the drying chamber (3). The feed inlet comprises a decanter centrifuge (9) having an axis of rotation (19), a first axial end (21), a second axial end (23) and a solid phase outlet at the first axial end (21). The drying chamber has a common drying chamber outlet (17) for dried powder and spend drying air. A product conduit (25) is connected to the common drying chamber outlet for pneumatic conveyance of the dried powder through the product conduit. The air inlet (15) is configured to provide a swirl of drying air inside the drying chamber (3). The drying chamber (3) generally has a disk-shape with a circumferential wall (31), a part of which constitutes the bottom wall portion (7). The drying chamber (3) has a tangential drying chamber outlet (17) and preferably a tangential air inlet (15) for entering at least part of the drying air.
