The deep knowledge of powder Attributes and speedy and reliable measurement procedures become a prerequisite from the context of constant approach chains that will need to right away reply to product residence modifications to keep processes and item high quality steady in just specified ranges. To attain this, well-made design techniques need to be derived to predict and Handle any complex powder processing Procedure. This Special Situation is dedicated to in-depth reports presenting basic development from the scientific area of powder processing in pharmaceutical purposes. Contributions address extensive Perception into device operations using design strategies that present predictions of outcomes like overmixing, applied flow attributes, and residence time distribution dependant on product Qualities and method parameters.

To stop clogging with the valve orifice and to maintain the uniform application of powder, the particles should be of a particular size selection. For powder for being sprayed efficiently, it should contain particles smaller sized than 50 microns if it is to become packaged like a powder spray.
