Process advantages
Pan coating is used primarily for masking taste or for applying
protective films.
Large particles, which are not suitable for the fluid bed process
(e.g. tablets, capsules and large pellets), can be coated with this
process.
The main advantage is the gentle mixing and coating of tablets due
to the geometry of the drum and the Fischer mixing blades specially
developed by Glatt. These ensure absolutely homogeneous mixing with
minimum stress on the product.
Overall, the sum of all the measures taken together guarantees an
extraordinarily high coating quality.
The shortest possible process times can be achieved due to the fully
perforated drum.
Principle of operation
Glatt offers Drum
Coaters with batch sizes from 500g to 2000kg/batch.
When Film Coating is
carried out in the Glatt pan coater, a film solution is applied
to the particles from above by means of a two-material nozzle.
The particles are moved and mixed by the rotating drum. The introduction
of the process air evaporates the fluid and dries the film coating.
Softening of the particle surface is avoided by the selection of
the appropriate process parameters.
The necessary efficient heat transfer is achieved by the fully
perforated cylindrical part of the drum. In the figurative sense,
this also applies to Sugar
Coating.
