Can a counter-rotating twin-screw extruder be used with dehulled sunflower seeds?
The use of a counter-rotating twin-screw extruder with dehulled sunflower seeds seems to result in a particularly high process efficiency and productivity, at a relatively low cost (0.11 kW·h/kg oil produced) (Isobe et al., 1992). However, in this case, the cost of the dehulling treatment should be taken into account.
What is the oil extraction efficiency of rapeseed & sunflower seeds?
With this configuration, a high oil extraction efficiency of between 81 and 85% and between 85 and 90% was found for the pressing of rapeseed and sunflower seeds, respectively, at a feed flow rate of 70 kg/h (Bouvier and Guyomard, 1996).
Can a co-rotating twin-screw extruder extract sunflower oil?
A limited number of studies have been conducted on the development of an aqueous extraction process using a co-rotating twin-screw extruder for the recovery of sunflower oil (Evon et al., 2007, Evon et al., 2009, Evon et al., 2010a, Evon et al., 2010b).
Is twin-screw extrusion a sustainable vegetable oil extraction method?
Twin-screw extrusion shows high potential for sustainable vegetable oil extraction. Increased economic feasibility for twin-screw pressing versus single-screw pressing. Innovative extrusion processes combine pressing and green solvent extraction. Extensive additional research is necessary prior to industrial implementation.
How can reverse screw elements be used to extract sunflower seeds?
Spacing of the reverse screw elements, i.e. the positioning of a forward conveying screw elements in between two reverse screw elements, was shown highly effective as a means for increasing the extraction efficiency of the mechanical pressing process of sunflower seeds (Kartika et al., 2005, Kartika et al., 2006).
What is the effective filtration zone for thermomechanical pressing of sunflower seeds?
For the thermomechanical pressing of sunflower seeds, the reported effective filtration zone in terms of feed rate and screw speed corresponds to a filling coefficient CF of between 0.05 and 0.20 kg/h rpm, with superior extraction efficiencies for the highest levels of the filling coefficient (Dufaure et al., 1999a).
