Mastering Drying and Granulation A Guide to
Fluid Bed Dryers and ONFD Machines from VJ
Instruments At VJ Instruments, we understand the
importance of efficient and reliable drying and
granulation processes in the pharmaceutical
industry. These steps directly impact the
quality, consistency, and functionality of your
final products. Here, we delve into the world of
fluid bed dryers (FBD) and Optional Nose Filter
Dryer (ONFD) machines, exploring their
functionalities and how they can empower your
pharmaceutical production. The Power of
Fluidization Fluid Bed Dryers (FBD) The FBD is a
versatile and widely used piece of equipment for
drying a range of materials, particularly powders
and granules. Its unique operation offers several
advantages over traditional drying
methods Gentle and Uniform Drying Unlike
conventional dryers that rely on direct heat
exposure, the FBD utilizes a fluidization
technique. Air, heated to a specific temperature,
is passed upwards through a perforated bed
containing the wet material. This creates a
fluidized state, where the particles behave like
a boiling liquid. This gentle, uniform drying
minimizes the risk of thermal degradation,
ensuring the integrity of your product. High
Efficiency and Fast Drying Times The fluidized
bed allows for excellent contact between the
drying air and the particles, significantly
accelerating the drying process compared to
static bed dryers. This translates to faster
production cycles and increased
efficiency. Improved Product Quality FBDs
promote a more uniform drying process, leading to
consistent moisture content throughout the
product. This consistency is crucial for
maintaining the desired characteristics and
performance of your final product, such as tablet
disintegration or capsule flowability. Closed-Loop
Operation Many FBDs operate in a closed-loop
system, minimizing dust exposure and solvent
loss. This feature is particularly advantageous
for handling potent APIs or volatile materials,
ensuring a safe and controlled work
environment. Applications of FBDs in the

The Enhanced Solution Optional Nose Filter Dryer
(ONFD) The ONFD machine builds upon the core
functionalities of the FBD while offering
additional benefits for specific applications.
Here's how the ONFD sets itself apart Improved
Fines Containment The ONFD incorporates an
additional filtration stage positioned above the
product chamber. This additional filter, also
known as a "nose filter," captures any fine
particles that may escape the main filter during
the drying process. This enhanced filtration
minimizes product loss and ensures a cleaner
working environment. Ideal for Potent APIs The
superior fines containment offered by the ONFD
makes it particularly suitable for handling
potent APIs. It minimizes the risk of operator
exposure to these potent materials, enhancing
safety and compliance with regulations. Reduced
Dust Emissions By capturing even the finest
particles, the ONFD contributes to a cleaner
production environment with minimal dust
emissions. This is especially beneficial for
processes involving materials with nuisance dust
or those that pose respiratory health
risks. Choosing the Right Drying Solution The
selection between an FBD and an ONFD depends on
your specific needs and the materials you handle.
Here's a quick guide FBD Ideal for most drying
applications in the pharmaceutical industry,
particularly when gentle drying and high
efficiency are the primary concerns.

ONFD Best suited for handling potent APIs,
materials prone to generating fines, or
situations where dust control is a critical
priority.
Beyond Drying Fluid Bed Granulation While drying
is the primary function of FBDs, some models
offer additional capabilities like granulation.
This process involves transforming fine powders
into larger, more uniform granules suitable for
tableting or capsule filling. Fluid bed
granulation offers several advantages Improved
Flowability Granules flow more freely compared
to fine powders, minimizing issues during capsule
filling or tableting processes. Enhanced
Disintegration Granules typically disintegrate
faster than powders when taken orally, leading to
quicker drug release profiles. Uniform Content
Distribution Granulation promotes a more uniform
distribution of APIs and excipients within the
final product, ensuring consistent dosage
delivery.
