Solid dosage pharmaceuticals have often required a separate granulation step in the production cycle to avoid segregation and to produce a powder that has the correct flow properties to accommodate a high-speed tablet press.
When this cannot be obtained in a traditional
spray dryer, then the
Fluidized Spray Dryer FSD™ - where a granulation step is made an integral part of the continuous
spray drying process – is an obvious choice. The FSD™ concept is a technique pioneered by GEA Niro. The FSD™ technology can also be used to achieve low residual volatiles content in the final spray dried powder. This result in not only a more streamlined, efficient production process, but it also reduces cost and post contamination is avoided.
