Fluidized bed drying is the ideal process for controlled, gentle and even drying of moist powders, filter cakes and granulates with a high residual moisture. Thanks to the intensive heat and material transport, this process is both time-saving and effective. Drying in the fluidized bed is also suitable for ultimately eliminating residual moisture from granulates and particles after spray granulation. However, if a certain residual moisture is intentional, this can easily be achieved by set temperatures in the fluidized bed.
Process
Fluidized bed plants are ideal for drying wet solids. Hereby, the process air that flows through the fluidized bed is pre-dried and conditioned in such a way that it can absorb the moisture of the product to be dried. Another advantage of fluidized bed dryers: Thanks to the excellent material and heat exchange, the drying in the fluidized bed works efficiently even at low temperatures.
Fluidized bed drying also achieves optimum results as redrying– e.g. in spray-dried or spray-granulated, extruded or mixer-manufactured products. It guarantees perfect results when very low residual moisture values are demanded.
Advantages
- Evaporation of large quantities of water in a short time
- Homogeneous and gentle conditions
- Defined temperatures ensure the desired residual moisture
