  • 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.
  • 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).
  • What is a twin-screw extruder?
  • Specific designs of twin-screw extruders for the pressing of oilseeds were developed in the 1990s, a process that was mainly driven by extruder manufacturers (Bouvier and Guyomard, 1996). These extruders consist of two intermeshing, co-rotating or counter-rotating screws mounted on splined shafts and enclosed in a modular barrel.
  • Does a twin-screw extruder reduce oil recovery?
  • As an illustration, a decrease in oil recovery from 82 to 62% was found during the thermomechanical pressing of sunflower seeds using a twin-screw extruder of increasing volume and an increased feed rate from 14 to 22 kg/h, respectively, while maintaining the raw material characteristics and operating conditions (Dufaure et al., 1999a).
  • 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.
  • Does a twin-screw extrusion affect the pressing process?
  • Even though no studies analyzing the varietal effect or the influence of cultivation conditions on the pressing process have been reported for twin-screw extrusion so far, these parameters have been shown to exert a significant impact on the single-screw pressing process (Savoire et al., 2010, Zheng et al., 2003).
