Fluid Bed Dryers

SiccaDania fluid bed dryers are designed to be cost-effective. They are built according to the principle of modularisation. This allows for a customised design without adding extra costs. By having one air outlet for exhaust air, the installation and running costs of the fluid beds are also reduced. In the fluid beds, separation takes place above the perforated plates, which reduces the loss of fine powders and thereby increases the yield.

SiccaDania provides both internal and external fluid beds. Whether our spray dryers are equipped with an internal fluid bed or an external fluid bed or both depends on the application of the specific plant.

The internal fluid bed is often used for secondary drying at lower temperatures and to prevent deposits on the conical sides of the drying chamber. With an internal fluid bed, the operator has more control and can fine-tune to the exact product specifications. This is possible by controlling the retention time in the dryer by adjusting the powder layer by means of a weir.

The external fluid bed can be divided into several sections, depending on the application. The external fluid bed is either a standalone unit for specific functionality powders, or it is an integrated part of the spray drying system. Either of these configurations will apply the final drying and cooling of the product.
