Low screw speed was found to have greater effect on the properties of the foams than did the high screw speed.
According to Table 3, screw speed (8.12 %) and melt temperature are significant factors.
Residence time distributions differed according to starch type (amylose content, hydroxypropylation) and screw speed.
The mixing time, temperature, and screw speed were set at 5 min, 280 °C, and 45 rpm, respectively.
The processing temperature and screw speed of the extruder were adjusted at 190 °C and 250 rpm, respectively.
The optimal condition of extrusion parameters was obtained as screw speed 70.30 rpm, temperature 68.10 °C and brix 18.0°.
At low SFL the median residence time was mainly fill-level dependent and at higher SFL mainly screw speed dependent.
This approach allowed evaluating the influence on the process of four variables (ultrasonic amplitude, temperature, screw speed and flow rate).
The first architecture (Configuration Chain) predicts the process variables screw speed N and water content w starting from product characteristics.
For concentrations of MWNT near the percolation threshold, the processing conditions (screw speed and mixing time) were varied.
Liquid to solid (L/S) ratio, screw configuration and screw speed parameters on the twin screw granulator were varied, with output granule and tablet properties characterised.
