Starchy Product: Coupling SME and Viscosity for a Better Prediction

The extrusion of starchy products is a tricky process as it modifies the basic structure of the material (loss of the grain structure, degradation of amylose and amylopectin chains…). The objective of this study is to predict with Ludovic® the starch transformation considering the influence of the Specific Mechanical Energy (SME) on the intrinsic viscosity. […]


Experiments of Classic PP Extrusion

As a classic thermoplastic, the polypropylene (PP) material presents a well known behaviour during the extrusion process. Its behaviour can be easily controlled during extrusion. In this context, the numerical simulation allows to quickly identify the key zones of the process. The PP behaviour in twin screw extrusion has been studied in many publications*. In […]
