Dry Powder Mixing Is Feasible in Continuous Twin Screw Extruder: Towards Lean Extrusion Process for Oral Solid Dosage Manufacturing
Contributor(s):: Mateo-Ortiz, Daniel, Villanueva-Lopez, Vladimir, Muddu, Shashank Venkat, Doddridge, Gregory D., Alhasson, Dana, Dennis, Michael C.
Using discrete element method (DEM) modeling and near-infrared (NIR) spectroscopy, the feasibility of powder mixing in the initial pre-melting zones of a twin screw extruder using two independent feeders was studied. Previous work in the pharmaceutical and food industry has focused on mixing when...
