Fluid Bed Rotor
Our organization manufactures high qualityFluid Bed Rotor.
Fluid bed rotor process by principle is essentially a horizontal
wurster process, because it fully utilizes the 3 main features below.
- Concurrent spraying takes places below the product bed without premature droplet evaporation.
- High centrifugal energy is created inside the product bed by the
rotating disc. The process air which enters the process chamber
vertically at the periphery of the rotating disc reinforces the
product's helical motion, so that practically every particle is
permanently rolling around its own axis.
- Regular, statistical reproducible exposure of the particles to the spray nozzle by means of a defined disc rotation speed.
Analysis have shown that the rotor induced centrifugal forces move the
entire product bed creating a denser film deposition. i.e. To obtain a
wurster identical drug release profile, one would have to apply a
little less coating agent with the rotor.
Our Rotor is not limited to film coating only, but permits a number of processing options.
Rotor granulation can be accomplished by spraying a suitable binder
suspension on powders. Both granulate production and spher'oidization
is completed by the spherical rope motion of the formulation. The final
stage drying can be rapidly achieved as the large free area around the
rotor disc allows the throughput of large air volumes.
Pelletization, such as the production of non-pareils, is accomplished
by rapid powder and binder addition onto dummy seals through a single,
combined bottom spray nozzle (in this case tangential spray). This
process allows weight gain of approximately 250% per hour.Specifications
