Evaluation of Polyvinyl Alcohol as Binder during Continuous Twin Screw Wet Granulation [PDF]

Pharmaceutics
Binder selection is a crucial step in continuous twin-screw wet granulation (TSWG), as the material experiences a much shorter residence time (2–40 s) in the granulator barrel compared to batch-wise granulation processes. Polyvinyl alcohol (PVA) 4-88 was

3D Population Balance Model for Continuous Twin Screw Granulator

Chemical Engineering Transactions, 2013
Continuous processes could be applied to improve cost-efficiency of pharmaceutical manufacturing that has traditionally relied on batch processing due to regulatory requirements and small lot sizes.

Twin Screw Melt Granulation of Simvastatin: Drug Solubility and Dissolution Rate Enhancement Using Polymer Blends [PDF]

Pharmaceutics
Background/Objectives: This study evaluates the efficacy of twin screw melt granulation (TSMG), and hot-melt extrusion (HME) techniques in enhancing the solubility and dissolution of simvastatin (SIM), a poorly water-soluble drug with low bioavailability.

Effect of Mixing Elements on Granule Formation in Hot Melt Twin Screw Granulation

Chemical Engineering Transactions, 2021
Twin screw granulation (TSG) has been applied to wet granulation, although its application in melt granulation has been more limited. This work explores potential advantages of hot melt granulation using twin screw extrusion.

Identifying Critical Binder Attributes to Facilitate Binder Selection for Efficient Formulation Development in a Continuous Twin Screw Wet Granulation Process

Pharmaceutics, 2021
The suitability of pharmaceutical binders for continuous twin-screw wet granulation was investigated as the pharmaceutical industry is undergoing a switch from batch to continuous manufacturing. Binder selection for twin-screw wet granulation should rely

Parametric Study of Residence Time Distributions and Granulation Kinetics as a Basis for Process Modeling of Twin-Screw Wet Granulation

Pharmaceutics, 2021
Twin-screw wet granulation is a crucial unit operation in shifting from pharmaceutical batch to continuous processes, but granulation kinetics as well as residence times are yet poorly understood.

Asymmetric distribution in twin screw granulation [PDF]

European Journal of Pharmaceutics and Biopharmaceutics, 2016
Positron Emission Particle Tracking (PEPT) was successfully employed to validate measured transverse asymmetry in material distribution in the conveying zones of a Twin Screw Granulator (TSG). Flow asymmetry was established to be a property of the granulator geometry and dependent on fill level. The liquid distribution of granules as a function of fill

Particle-Scale Modeling to Understand Liquid Distribution in Twin-Screw Wet Granulation

Pharmaceutics, 2021
Experimental characterization of solid-liquid mixing for a high shear wet granulation process in a twin-screw granulator (TSG) is very challenging. This is due to the opacity of the multiphase system and high-speed processing.
