In a poster presentation at the 2009 AAPS Annual Meeting and Exposition, materials scientists from Freeman Technology will describe collaborative work with machinery manufacturer Harro Hofliger.
The joint development project was established to address the challenges of specifying low-friction materials of construction for pharmaceutical powder processing plant.
Using the Freeman Technology FT4 Powder Rheometer to test a variety of materials supplied by Harro Hofliger, methods have been developed for the consistent measurement of Wall Friction Angle for low-friction surfaces.
Low-friction materials allow powders to flow easily through the process with minimal residue and give process designers flexibility with respect to equipment wall and valley angles to promote mass flow.
The FT4 is a universal powder tester combining blade methodology for measuring flow energy with a range of shear cells, wall-friction modules and other accessories for measuring bulk properties.
The FT4 is sensitive in evaluating the force and torque on the powder/test material combination, and its control software automatically detects a steady state.
The exposition will take place on 8-12 November 2009 in Los Angeles, US.
