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.
