Work Principle
The powder granule in vessel (fluid bed) appears in a fluidized
state. It is preheated and mixed with clean and heated air. At the
same time the solution of adhesive agent is sprayed into the
container. It makes some of the particles become granule that
contains adhesive. Being of unceasing dry through hot air, the
moisture in the granule is evaporated and the adhesive agent is
solidified. The process is carried out continuously. Finally it
forms ideal, uniform and porous granules.
Process technical features
Mixing, granulation and drying processes are completed in one step
inside the machine;
The operation is safe because the anti-static filtering cloth-bag
is applied for the bag filter.
By powder granulation process, the fluidity is improved and the
dust leakage is reduced;
By powder granulation process, its solubility is improved,the
prepared granules are instant , and granules are soluble, tablets
are easy to disintegrate.
It's safe for operator if explosion takes place, because an
explosion proof type pressure-releasing vent is set, as is
described that turn to the Ex-type of Fluidized bed dryer, we set
the explosion release vent on the machine. Once the explosion
happened , the machine will release the explosion to outside
automatically and safely, it will make/obtain a very safe condition
to the operator.
For the process of loading material, we have choices such as vacuum
feeding, lifting feeding, negative pneumatic-conveyance feeding and
manual feeding for customer selection.
No dead corners. Therefore the loading and unloading are quick, and
it can be washed clean, so it meets the requirements of GMP.
The degree of automation is further improved, and the operation is
simple, so the stability of product quality can be effectively
guaranteed. This machine adopts PLC automatic control, all the
operation according to the requirements of the user to set the
process parameters automatically, can print all the process
parameters, the original record is true and reliable. In full
compliance with the GMP requirement of pharmaceutical production.
In order to guarantee the stable quality, PLC automatic programming
control mode is adopted, and working point flow chart with
computerized dynamic display system for operation control;
excellent operation control configurations guarantee the high
reliability for plant’s movement and that the running parameters in
the system will not be influenced by artificial and outside
factors. The operation control principles are as below:
① For critical control points, we adopt imported electrical
components, setting multiple interlocking and mutual interlocking;
② Digital instrument display, control for inlet and outlet
temperature, over-temperature alarm; display , control and alarm of
the temperature inside fluid bed;
③ Proportional adjustment valve realizes precise temperature
control, whose accuracy reaches to ±1℃；
④ Differential pressure indicator for air distributor and filter;
⑤ Safe pressure-releasing: There equipped with an Expro. Membrane
(venting channel) at the side, and once the pressure is excessively
high inside of drying chamber,the membrane will be broken through
and the high pressure will be released outside of the chamber;
For the machine, CIP and WIP is available, as is based on
customer's choice.
It is particularly suitable for powder or granular material, and
due to the drying time is short, and the relative velocity between
material and hot air is big, therefore it is suitable for
heat-sensitive material.
Drying capacity is high: due to the material is exerted by the
wash-out, bumping, and omni-bearing drying by the hot air, thus
specific surfacial area is enlarged, accordingly it strengthens the
mass and heat transfer, and the drying capacity is high.
Efficiently controlled final moisture: generally the moisture of
material can be controlled within a certain scope, plus free
setting of drying time, through the united co-ordination with inlet
and outlet temperature, finally the fluid bed drier can control the
final moisture index.
The new and original pulse type duster: filtration core is made of
stainless steel woven mesh screen specially. This kind of
corrugated filtration core possesses: big air-ventilating amount,
high filtration efficiency, easy washing, a strong replacibility,
good performance of anti-static and high-temperature resistance.
Obtaining environmental protection standard: the system runs in a
sealed and negative pressure situation, which avoids dust flying
out; meanwhile there is no dead corners for cleaning and washing,
either there is no intersecting contamination, therefore the
potential risk of contaminating the operation environment is
eliminated.
Low labor intensity: according to different material, different
methods for feeding and discharging are adopted as to obtain
automatic and continuous feeding and discharging.
Plant advantages in Configuration
The main configuration components of the plant are powerful in
functions, advanced in design, superior in performance, and
reliable in quality and etc.. These all ensure that this plant has
a high cost performance from all aspects, so that customers can buy
happily and use it with confidence.
