Heated process air is supplied to a special perforated distributor bed plate. Via the bed plate the hot air flows through the layer of solids at a velocity sufficient to support the weight of particles in a fluidized state. The heat in the air is used to evaporate moisture from the product. The drying air picks up moisture and cools down during the evaporation. This means that for example the supply air can be 90°C but as a result of […]
