FG Series Fluidizing Bed Dryer

Because the FG series vertical fluid bed dryer is a vertical static dryer, the vertical fluid bed dryer occupies a small area, so it is very suitable for clean workshops.

The Fluidized bed drying machine is the optimal method for controlled, gentle, and even drying of wet solids. The intensive heat/mass exchange of the fluidized bed product makes this method particularly effective and time-saving. The technology is also suitable for post-drying of spray granulated or extruded products with very low residual moisture.

The Vertical fluid bed dryer can be used in the entire powder processing industry. In the pharmaceutical industry, this innovative method has replaced the time-consuming tray drying long ago: The drying process with fluidized bed drying reduces the drying time in the hot air drying oven by approximately twenty times. In addition, a fluidized bed drying machine provides controlled and uniform drying conditions compared to the uneven drying in trays.

No matter whether the product was produced in the fluidized bed granulator or a high-shear mixer, whether in batch or continuously: With a vertical fluid bed dryer, it must be ensured that drying always takes place in thermodynamic equilibrium. The inlet air temperature must be selected such that only so much moisture evaporates from the surface of the granulate as is transported through the capillaries from the interior of the granulate to the surface. If the inlet air temperature is too high, a surface crust will most likely form which will hamper or even prevent the moisture from being transported from deeper layers to the outside. This will delay the entire drying process rather than accelerate it.

A properly used, Vertical Fluid bed dryer provides an efficient solution for the gentle and even drying of your product.

The only difference between the fluidized bed granulator and the vertical fluidized bed dryer is the liquid spray system;  adding a set of liquid spray system to the vertical fluidized bed dryer becomes a fluidized bed granulator.

A vertical fluid bed dryers are an important equipments for solid dosage form lines (granulation line equipment). The solid dosage form line includes High shear granulator, conical mills, fluidizing bed dryer, Vacuum conveyor, IBC powder blender, Powder shifter and packaging machine.
