Disclosed herein is an external mixing pressurized two-fluid nozzle for atomising a liquid by means of liquid pressure and gas, comprising an inner feed liquid pipe () extending axially between an upstream end and a downstream end, having a feed liquid conduit (), a feed liquid inlet () positioned at the upstream end and a feed orifice () positioned at the downstream end, and a co-axial first gas pipe () extending radially outside the inner feed liquid pipe () and forming a first gas conduit () between the first gas pipe () and the inner feed liquid pipe (), the first gas pipe () having a gas outlet slit () positioned at the downstream end. Said external mixing two-fluid nozzle provides a swirling motion of the gas, which combined with a pressurized feed liquid enables the production of spray dried powder at industrially applicable capacities with low energy consumption and a small particle size.
