A one dimensional model for the prediction of extraction yields in a two phases modified twin-screw extruder [PDF]

, 2002
Solid/liquid extraction is performed on raw plant substrate with a modified twin-screw extruder (TSE) used as a thermo-mecanochemical reactor. Visual observations and experimental residence time distributions (RTD) are used to develop a solid transport ...
