the effect of shear rate on dissolution of carbon dioxide in viscoelastic wheat flour matrix and cell density in a glass barrel twin screw extruder is investigated. it is found that by increasing the shear rate there will be a decrease in the required thermodynamic conditions and hence, it improves blowing agent dissolution and increases the cell density. shear rate breaks up big bubbles and he...

blends of sorghum and soybean flours were processed in a co-rotating twin screw extruder to prepare expanded product. response surface methodology (rsm) was used to study the effect of soya level (sl), feed moisture (fm), barrel temperature (bt) and screw speed (ss) on extruder system parameters and physical properties of the extrudate. response variables were product temperature (pt), motor to...

A growth and digestibility study was conducted using Osmanabadi goat male kids by feeding complete diets in the form of mash or expander extruded pellets containing different levels of red gram (Cajanus cajan) straw (RGS). Two iso-nitrogenous complete diets were prepared by incorporating RGS at 35% and 50% levels. Half the quantity of each complete mash feed was then converted into pellets thro...

The objective of this study was to evaluate the feasibility of an aqueous process to extract the residual oil from sunflower press cakes using a co-rotating twin-screw extruder. Two different configurations were tested: the expression fromwhole seeds followed by the aqueous extraction, in two successive apparatus or in the same one. For the aqueous extraction stage, the oil yield depended on th...
