Changes in the parameters of the transfer function of a twin screw extruder
Journal Title: Annals of Warsaw University of Life Sciences- SGGW - Agriculture - Year 2015, Vol 66, Issue 66
Abstract
The objective of this work was to determine the static characteristics and then the transfer function of the process of extrusion for selected process variables, such as screw rotational speed (n) and raw material flow rate (Q). In the study, the process of extrusion of a mixture of raw brewers' grains and maize cereal of humidity of 18%. Tests were conducted using the Clextral EV25 twin screw extruder. It was found that the extrusion process was an object that reflected well the areas of variability of parameters, such as object gain, time constant and transfer function.
