can any one please explain how to do FBD equipment qualification, if possible pls share the draft copies
Hello and welcome!
A Fluid Bed Drier (FBD), just like any other critical equipment must be qualified. DQ, IQ, OQ, and most interestingly PQ. Most equipment share the same qualification methodology for their DQ, IQ and some OQ tests are very similar between different equipments; however, PQ tests differ greatly because they depend on the specific process and product characteristics.
One of the most important tests during FBD qualification is the testing of residual humidity in your powder, giving that this is the intended purpose of the equipment. Basically you take samples and test for residual moisture and make sure it meets specifications homoeneously in whole batch.
If you have a more specific question regarding the qualification if this type of equipment, let me know so that I can elaborate further.
