Powders are challenging materials to work with. Flow properties have critical significance in the pharmaceutical industry, which is why understanding powder behaviour in various unit operations like blending, compression, volume filling and various other scale-up techniques as well as in the storage and transportation is utmost important. Although there are many well established tests to evaluate flow properties, they lack to interpret the effect of process and test conditions on the flow behaviour. With the help of Powder Rheometer, the process conditions can be simulated thereby enabling one to evaluate the powder flowability in consolidated, aerated and confined states. Rheometer is also called as the ‘Universal Powder Tester’ as it evaluates powder flow in bulk, dynamic and shear states with accuracy and sensitivity. This paper provides insights about the powder characterization in dynamic flow, bulk and shear by FT4 Powder Rheometer.
