Orthos Engineering – How does a Fluid Bed Dryer work?

The shaking action of the bed assists in the transportation of the material over the length of the dryer. Moisture is carried away by the air into a dust recovery system, whereby the hot air can be recycled in a closed loop back to the process. The flow of air is controlled along the length of the dryer to maximise fluidisation, enabling very wet and sticky materials to be handled. As the ...
