A twin-screw oil press can be expected to solve these problems because of the higher transportation force, similar to a gear pump, and better mixing and crushing at the twin-screw interface. A twin-screw press (screw diameter=136 mm, length/diameter=6.5, screw speed 1500 rpm, feed rate=5050 kg/h) was designed with partially intermeshing and counter-rotating screws and was tested on dehulled sunflower seed.
Dehulled sun-flower seed (wt, 6.0%; oil, 58.6%) without pretreatments (crushing or cooking) gave 93.6% oil recovery with the twin-screw press, in contrast to 20% oil recovery with the single-screw press. The oil expressed with a twin-screw press had less foreign material than the oil from the single-screw press.
Get PriceThe fatty acid methyl esters extraction of sunflower oil using a CLEXTRAL BC 45 co-rotating twin-screw extruder increased oil extraction yield up to 96% and decreased residual oil content in cake meal below 5% under solvent-to-solid ratio of 0.70 (Amalia Kartika et al., 2003). In addition, the solvent-to-solid ratio and the screw configuration affected oil extraction yield.

Get PriceAs well as screw configuration, the preparation of the raw material is also important to enhance oil extraction. The oil extraction yield from whole sunflower seeds in a contra-rotating twin-screw press was low (75%), but could be increased to 93.6% if raw materials was dehulled (Isobe et al., 1992).
