Fluid Bed

The fluidized bed dryer puts fluid materials such as powders, pastes (or even suspensions and solutions) on a perforated plate and other air distribution plates, and sends them into a drying medium with a considerable speed from the lower part. When the flow rate of the medium is low, the gas flows between the material particles, and the entire material layer does not move; gradually increase the gas flow speed, the material layer begins to expand, and the gap between the particles increases; then increase the gas flow speed, and a considerable part of the material is suspended. , Forming a gas-solid mixed bed, that is, a fluidized bed, because the suspended material in the fluidized bed is like a boiling liquid, it is also called a fluidized bed, and it presents fluid properties in many aspects. Therefore, the air flow speed is the most fundamental control factor of the fluidized bed dryer, and the appropriate air flow speed should be between making the material layer begin to fluidize and bringing the material out.
