Abstract: In the method and apparatus (1) for drying a fluid or wet product, a drying chamber (2), an air inlet, a feed tank (3), and a product recovery system (14) are provided. During operation, a fluid or wet product is fed from the feed tank into the drying chamber at a predetermined flow rate, and finished dried product is fed into the drying chamber at a flow rate corresponding to controllable settings. The fluid or wet product is mixed with the finished dried product in the drying chamber. The mixture of fluid or wet product and finished dried product is dried in a gas containing finished dried product, and the product is recovered from the gas in the product recovery system.

Abstract: 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 (1) extending axially between an upstream end and a downstream end, having a feed liquid conduit (2), a feed liquid inlet (3) positioned at the upstream end and a feed orifice (4) positioned at the downstream end, and a co-axial first gas pipe (5) extending radially outside the inner feed liquid pipe (1) and forming a first gas conduit (6) between the first gas pipe (5) and the inner feed liquid pipe (1), the first gas pipe (5) having a gas outlet slit (7) 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.
