When it comes to drying, how do
Fluid bed dryers do it best?
Introduction
• Nowadays, fluid bed dryers are widely used in the food processing
industries. The primary reason for such popularity is that these
machines improve the quality of products and reduce the drying time.
Moreover, this equipment operates hygienically and ensures excellent
safety. It is not only beneficial to the environment but also increases
cost-effectiveness by reducing energy consumption. VJ Instruments
consists of various products ball mill machine in pharmaceutics, cone
blender, morris water maze.
Fluid bed dryers are the equipment used in
pharmaceutical industries for different applications
such as mixing, drying, granulation etc.
• Fluid bed dryer are the equipment used in pharmaceutical industries
for different applications such as mixing, drying, granulation etc. The
fluidized air is used to provide an effective method of drying.
Everything about Fluid Bed Dryer can be explained
by dividing them into a fluidized bed and a drying
chamber.
• The main part of a fluid bed dryer is the drying chamber. This is the
box where you put your product, and it's what helps keep everything
moving. The walls of this chamber are made up of perforated trays
that hold a certain amount of drying medium.
• The second part of a fluid bed dryer is called the fluidized bed. This is
where most of your action happens: all those little holes in those
perforated trays allow air to flow through them, and when heated,
these air currents lift all your granules or powdery bits so they can get
evenly exposed to heat from above (from infrared lamps or
microwaves).
The fluidized bed is mounted on top of the drying
chamber.
• The fluidized bed is mounted on top of the drying chamber. It consists of two
concentric cylinders. The inner cylinder has a series of holes in it and the outer
one is made up of perforated plates. A high-velocity air stream blows through
these holes and carries with it all powders as well as gases produced by the
heating process, thus causing them to rise into a fluidized state.
• The powder mixture enters from below into this fluidized-bed where it gets
evenly distributed over its entire surface area due to turbulence caused by
high-velocity airflow. This ensures even drying of all ingredients present within
the mixture since there are no dead spaces left behind at any point during the
drying process which could prove detrimental to quality in case they were not
exposed to the sufficient amount of heat required for complete chemical
transformation (if any).
The fluid bed has an air inlet to provide the air and
a pre-filter to remove the dust particles from the
air.
• The fluid bed has an air inlet to provide the air and a pre-filter to
remove the dust particles from the air. The pre-filter is very important
because it helps prevent product damage caused by foreign particles
entering the drying chamber. The main purposes of this type of dryer
are mixing, heating, and cooling processes. It is used mainly for drying
all kinds of granular products like grain, feedstuff and pellets etc.; also
it can be used for liquids such as paints etc., which are commonly
applied by spray guns on various substrates (e.g., coils).
The air first enters the drying chamber and then via
a perforated plate or baffles into the fluidized bed.
• The air first enters the drying chamber and then via a perforated plate
or baffles into the fluidized bed.
Air is forced through the product layer with enough
energy to support it in a fluidized state.
• Air is forced through the product layer with enough energy to support it in a fluidized state. This means that there
are enough particles of air moving around the product to keep it “fluid” and not allow static electricity to build
upon the product's surface. Static electricity can cause problems when handling your dried product because you
will tend to pick up more than you intend due to its attraction properties.
• The fluidized air system also allows for better heat transfer rates than other types of dryers because air gets so
close to each piece of material as it passes through into the drum, which results in quicker drying times overall
because there is less opportunity for water molecules being left behind on any surface they come in contact with
during this process (including any type). There are also fewer chances for condensation inside between layers since
there is no pressure difference between areas where moisture may be present (such as at the bottom) compared
with those areas where little or no moisture could exist at all (like the top).
• As a result, everything gets mixed up very nicely due to which better quality granules can be made.
• As a result, everything gets mixed up very nicely due to which better quality granules can be made. The particles
can collide with each other more effectively and they can grow rapidly.
This process is generally called "Granulation".
• Granulation is the process of mixing and forming granules. In this
process, the wet powder is mixed with air at high velocity and at high
temperature to form granules. This method of drying is generally
called “Granulation”.
• Therefore, for granulation, the wet powder that has been added to
the pan of an fbd machine is mixed with air at high velocity to make
all particles behave as an aerated liquid, which allows each particle to
collide with other particles more effectively and rapidly resulting in
the rapid growth of granules.
Fluid Bed Dryers are useful for pharmaceutical
industries for mixing and drying purposes.
• Fluid bed dryers are used in industries to mix and dry. The main
purpose of using a fluid bed dryer is to ensure that the products are
dried uniformly.
• Fluid bed drying is done by heating the material inside a chamber that
has a circulating fluidized bed of tiny particles and hot air. This helps
in mixing, granulating, drying and so on. The heat transfer rate
through convection is higher than conduction because fluidization
increases the contact area with heated surfaces as well as increases
particle velocity which results in faster heat transfer rates than other
methods of drying like tray or belt type dryers.
Conclusion
• Our team at VJ Instruments has been in this industry for years, and
we know the ins and outs of fluid bed drying. We care deeply about
our craft and our customers, so if you have any questions, feel free to
reach out to us at any time. We look forward to hearing from you!
