Description

Spin Flash Dryer is used for continuous powder production from pastes and filter cakes without the need for grinding. It was developed and introduced in response to a demand to produce a uniform powder on a continuous basis from high viscosity fluids, cohesive pastes and sludge.

Spin Flash Dryer can be described as an agitated fluid bed. The tangential inlet, together with the action of the rotor, causes a turbulent whirling gas flow in the drying chamber. Thus, a balanced fluidized bed is formed which contains all intermediate phases between raw material and finished product. The dry powder is carried away as soon as it becomes light enough and achieves the desired moisture content. The heating of air may be direct or indirect depending upon the application. The dry powder is collected through cyclone separator/ bag filter or with a combination of both. The whole process takes place in seconds.
