Vertical Fluid Bed Dryer

Hywell Machinery FG series vertical fluid bed dryers are ideal for products that are free flowing. This type of fluid bed dryer is referred to as a static fluid bed because the fluid bed dryer remains stationary during operation. The static fluid bed processer provides an effective method of drying relatively free-flowing particles with a reasonable narrow particle size distribution. The feed may take the form of powders, granules, crystals, seeds, pre-forms, and agglomerates. A static fluidized bed dryer can be batch operation. Because there is no mechanical drive system to move the product, the static fluid bed processors are lighter and simpler to manufacture – hence cheaper than the dynamic fluid-bed dryers.
Units in continuous and batch types for more uniform materials that do not tend to agglomerate.

Vertical Fluid Bed Dryer Introduce

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. About the detail of this line, please learn our granulation line.

If the raw material is metal powder or granules, it needs to be dried or calcined, and the metal recycling rotary kiln of our company needs to be used.

Fluidized Bed Dryer Description

A Fluidized Bed Dryer is a one-stop drying machine that includes air handling units, stainless steel main tower (base part, product container, expansion chamber, and fluid bed dryer filter chamber), and an exhaust air system.

The main air heating system of the vertical fluidized bed dryer supplies the drying chamber with the designed amount of air. The air rate is calculated with Hywell machinery’s process calculation program. The program is based on the actual ambient conditions at the physical place where the dryer will be installed.

The main air system of a vertical fluidized bed dryer consists of air filters, pre-heating systems, an air heater, a supply fan, and from time to time dehumidification system(option). The main air system of the vertical fluidized bed dryer is constructed according to the actual requirements of the product and the ambient conditions.

A bag filter of the vertical fluidized bed dryers can be a standalone solution as this technology is able to remove the required powder fines before outlet to the atmosphere. The fines are collected in a fines return system, thereby the powder loss is reduced to a minimum. The fines can be re-entered to the top of the drying chamber, to achieve agglomeration of the powder or they can be sent to the internal or external fluid bed. Again, the required powder specifications will decide the design of the fines system.

Powder sifter (Option): The final step of the fluid bed drying system is the powder sifter. The powder sifter will separate the large powder particles from the powder, size is determined for the separation. The off size is bagged off and the powder can be either directly packed into big bags or conveyed to a silo system for other packing systems.

Heating Method of Fluidized Bed Dryer Machine

For the heating method of the Fluidized bed dryer machine, it can use steam or an electrical or burning gas furnace as a heat source. Hywell machine can design the different kinds of heating ways based on the client site situation. FL-5 Fluidized bed dryer machine just can use the electrical heater.

How do The Vertical Fluid Drier works

A vertical fluid bed system is a machine in which a flow of “wet” powder, granular, or flakes material is conveyed over a perforated bed. Hot drying air is blown through the holes of a perforated plate. The wet solids are lifted from the bottom and cause the solids to behave as fluid. The air velocity is adjusted to keep the moving layer of material fluidized.
