Particle-level residence time data in a twin-screw feeder

Modeling Residence Time Distribution in a Twin-Screw Extruder as a Series of Ideal Steady-State Flow Reactors

Knowledge about and control of residence time distribution (RTD) is critical for determining optimal conditions in an extrusion process. In this paper, previously proposed models for RTD have been summarized and compared with the experimental data. The best-fit model was found to be a plug flow in series with a finite number of constantly stirred tank reactors having dead volume fractions. Para...

Sequential calculation of torque in procedure of twin screw extrusion

The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...
