Distribution of binder in granules produced by means of twin screw granulation [PDF]

International Journal of Pharmaceutics, 2014
According to the quality by design principle processes may not remain black-boxes and full process understanding is required. The granule size distribution of granules produced via twin screw granulation is often found to be bimodal. The aim of this study was to gain a better understanding of binder distribution within granules produced via twin screw ...

Granule breakage in twin screw granulation: Effect of material properties and screw element geometry [PDF]

Powder Technology, 2017
Abstract This study is the first to explicitly measure the influence of material dynamic yield strength (DYS) and screw element geometry on the breakage process in twin screw granulation. Granule breakage is the key mechanism for controlling granule size within the Twin Screw Granulator.

Continuous twin screw granulation: Influence of process variables on granule and tablet quality [PDF]

European Journal of Pharmaceutics and Biopharmaceutics, 2012
The aim of the current study was to screen theophylline (125 mg) tablets manufactured via twin screw granulation in order to improve process understanding and knowledge of process variables that determine granule and tablet quality. A premix of theophylline anhydrate, α-lactose monohydrate and PVP (ratio: 30/67.5/2.5,w/w) was granulated with ...
