Discuss about Dria - coater? (Industrial Pharmacy - l)
Answers
Integrated Plenum Coating Pan
Partially perforated pans with integrated exhaust plenums were introduced to circumvent patents on the fully perforated side-vented pan. This design ensures that all the inlet air entering the pan is used in drying the product bed.
Potential Issues of Use for Film Coating Applications
Less efficient airflow
Cleaning of the exhaust ducts, which form part of the pan wall, may be difficult
Equipment Examples Include:
Freund Hi-Coater (Vector, USA)
Driam Driacoater (Driam, USA)
A partially perforated design was introduced by Driam, called the Driacoater. In this version both the inlet and exhaust air are via the perforated panels. This enables a reverse airflow option to be selected which may be valuable when coating very small tablets or particulates
