Advantages
Top Spray Advantage :
Optimized solubility
Lower fine generation
Bulk Density can be controlled
Different coatings, taste masking possible
Bottom Spray Advantage :
Allows Control release coating
Allows Enteric Coating & Active ingredient
Layering As well.
Several layer of coatings can be applied
Special Design Distribution plate with Air
barrier for better performance.
Rotor Technology Advantage :
Comparatively highly spherical &
less porous granules, as particle is
permanently rolling on its own axis
Rotor induced centrifugal force
creates a denser film deposition.
The rotor process provides the
ability to granulate, spheronize,
coat and layer
Granules with good content
uniformity.
Special Features
Top Spray Granulation :
The fluid bed granulation process (also known as
agglomeration) involves suspending particles in
an air stream and a suitable binding agent is
sprayed from the top into the fluidized bed (top spray). Particles in the path of the spray get slightly
wet and become sticky. The sticky particles collide
with other particles in the bed of material and
adhere to them to form granules. The
agglomerates formed are subsequently dried. In
addition to the very effective drying process,
granulation and coating processes with the top
spray method offers many advantages in the fluid
bed.
Bottom Spray coating :
The basic concept in Bottom Spray (Wurster)
the coating is to separate the particles in the fluid bed
from one another in an air (gas) stream.
While the particles are suspended, a coating
the formulation is sprayed from the bottom of the bed
up onto the particles (bottom-pray).
Rotor Technology
This processing technique is with its
physical principles quite similar to bottom spray coating, only that the product motion
is provided by a motor-driven rotor disc.
High Centrifugal Energy is created & co
current spraying takes place in the product
bed resulting in denser lm deposition.
Rotor granulation can be accomplished by
spraying a suitable binder suspension on
powders, granulation & spheronization is
completed by the spherical rope motion of
the formulation. The final stage drying can
be rapidly achieved as the large free area
around rotor disc allows a throughput of large
air volumes.
