Fluid bed technologyPresent challenges facing the pharmaceutical industry
include flexibility in production, processes that
are optimized for the long term, and fast production
procedures. Fluid bed technology from Hüttlin
offers all of these features and helps you to gain a
competitive lead.
Our Solutions have one thing in common – Quality
Hüttlin fluid bed lines make it possible to carry out drying, granulating
and coating/layering with just one product container. As a result,
it is no longer necessary to exchange the container. A more efficient
operation is ensured.
Making drying more efficient
The patented process gas distributor plate Diskjet ensures
fast and uniform mixing. Regardless of the drying conditions,
it allows for uniform fluidization of the entire batch.
The high exit speed of process air prevents sticking and
clogging of the product on the bed resulting in a product
with uniform residual moisture and improved reproducibility
of processes.

Process times significantly reduced Ñ
No dead zones in the product container Ñ
Reduced filter load Ñ
Processing of materials with different Ñ
densities is possible

Granulation better than ever
Depending on product characteristics and used binder,
the particle size of granulate can be controlled and
reproduced by selecting specific parameters. The uniformity
of the granulates and their homogeneous size distribution
produce excellent flow and pelletizing characteristics.
The efficiency of the system prevents large agglomerates
from forming in most products rendering classification in
a sieving mill unnecessary.
Coating and layering in a quality that has never been
seen before
Combined with the Diskjet, the three-compo-nent nozzle
delivers spray fluid straight into the fluidized product.
The fluid is coated at the site where the speed of the
product is highest ensuring even distribution of the spray
medium. The thin layer on the surface dries fast, with
virtually no agglomerates forming. In addition, the
evaporation energy above the Diskjet prevents thermal
load near the bottom from developing.
Granulating
Process times significantly reduced Ñ
Very homogenous granulate Ñ
No size calibration needed Ñ
Excipients (lubricants) can be added Ñ
High output on tablet press Ñ

Convinced by top-notch results
Hüttlin fluid bed granulation technology does not involve any milling of
the granulate for many products – a process that is still standard in
traditional fluid bed lines. The uniformity of the granulate means that
excipients (lubricants) can be added in the unit.

Any company laying claim to leadership in fluidized-bed technology must
constantly tread new paths to open up new horizons. This results in
technological feats such as the Diskjet gas distribution plate (patented),
the dynamic filter system (patented) and the three-component spray
nozzle spraying system.
Perfect mixing behaviour
The patented process gas bottom
ensures fast and thorough mixing as well
as short drying periods. Independently
of drying conditions, Diskjet produces
even fluidization of the entire filling.
A homogeneous air stream provides
optimum exchange of substance and

energy. The tangential gas exit improves
the efficiency of the filter system. The
high exit speed of process air prevents
the product from settling on the bottom
resulting in uniform residual humidity
of the product and processes with
enhanced reproducibility.
Inspired to think ahead

Optimum combination of fluid bed lines
Pneumatic discharging into two barrels
Hüttlin fluid bed lines have a modular design. The base devices are
designed as heavy-duty 10 bar or 12 bar pressure shock resistant and
can be adjusted using various options.
Depending on the requirements, product
containers are available either without
spraying systems, with tangential spraying
systems for simple or underbed spraying
systems for demanding applications.
The patented dynamic filter can be fitted
with different filter materials including
a fully CIP-compatible metal filter.
Pneumatic/gravimetric filling and
pneumatic discharging as a further option
offer significant advantages. As a result
they are generally used as a standard.

A retractable jet cleaner in the centre of the unit
rounds off the UltraClean system. With three
different positions, the 360°-rotating cleaning
nozzle guarantees that the unit is cleaned
completely. Thanks to computer-assisted
calculation of the spray nozzle opening combined
with the rotation speed of the jet cleaner it is
possible to optimize the cleaning design towards
the equipment requirements.
UltraClean (pat. pend.) – CIP in action
Hüttlin has made the CIP metal filter a viable solution. Metal filters with
mycron meshed screens collect cleaning solution in the clean gas side.
This can lead to long draining times in the cleaning cycle. Especially
products prone to swelling amplify this problem. Hüttlin has come up with
an ingenious solution: a metal filter that opens. An internal cone in the
filter cartridge such as the one used in the proven dynamic filter is pushed
downwards via a piston rod and the filter opens. This makes it possible to
rinse away solids on the clean gas side of the filter quickly, thus reducing
cleaning time significantly without compromising cleanliness.
Retractable jet cleaner
Fluid bed systems | 11
1. Preclean the product
area and the metal filter
from the outside with
the jet cleaner and blow
clear the metal filters
with compressed air.
5 Steps to perfect cleaning of the unit
CIP can be this easy when UltraClean (pat. pend.) is used.
2. Clean the metal filters
with the inside CIP nozzles.
This opens the metal filters.
3. Proceed with the main
cleaning of the unit using
the jet cleaner and rotating
spray nozzles in the
peripheral devices. Various
cleaning agents can be
added to the warm water
during this process.
4. Rinse the entire unit
and peripheral devices with
DI water as for the previous
step. The filters can
alternately be cleaned from
their inside and outside.
5. Dry the unit with
preheated process air while
the filter cartridges
alternate through an open
and close cycle.

Inline process – overall perfection
Inline process at Hüttlin means that the high-shear mixer granulator is
physically attached to the fluid bed system using a product transfer line.
The product is extracted from the high-shear mixer granulator using
negative pressure and transported to the fluid bed with the process air.
Regardless of whether a cone mill is interposed or whether the product is
a difficult one, Hüttlin can rise to the challenge. Minimum transfer times
combined with a maximum degree of emptying are proof of this. Closed
product handling is proven technology at Hüttlin.

*** For standard applications
The variety in requirements on modern control systems means that it
must be possible to adjust them flexibly. Hüttlin’s control systems
were developed based on this premise. Their modular structure can be
adapted very easily, from control of an individual machine to entire
production lines and integration into ME-systems.
Based on a Siemens or Allan Bradley PLC,
the control system was consistently
developed according to GAMP guidelines
and is extended to include a PC above
a certain scope. Provicon fulfills all
requirements of the FDA 21 CFR part 11.
PAT Integration
Process monitoring is one of the most
important measures for meeting and
reproducing the required quality.
Device control and process monitoring
In addition to monitoring conventional
indicators such as temperature, torque,
pressure and flow rate for liquid binder
and strip gas, Hüttlin provides monitoring
of product humidity and particle size
distribution. A NIR (Near Infrared) sensor
can be integrated for inline monitoring
of the product quality, residual
humidity, mixing quality and particle
size distribution.
