A new twin-screw press design for oil extraction of dehulled sunflower
A twin-screw press (screw diameter=136 mm, length/diameter=6.5, screw speed 15–100 rpm, feed rate=50–150 kg/h) was designed with partially intermeshing and counter-rotating screws and was tested on dehulled sunflower seed. The results were compared to a single-screw lab-scale press.
Besides the direct aqueous extraction of the oil from sunflower seeds (Evon et al., 2007), this study aimed to show that a co-rotating twin-screw extruder could also be used in an aqueous extraction of the residual oil from press cakes produced after pressing of the whole seeds to improve the total oil yield.
A Twin-screw extruder for oil extraction: I
A new process, in which sunflower seeds are pressed in a. twin-screw extruder, is examined here. The screw profile was. first optimized. Oleic sunflower seeds were crushed and 80% of. the oil
A number of authors have reported higher grade oil and press cake quality from twin screw extrusion, compared to single-screw extrusion (Offiah et al., 2018 and Kartika et al., 2010).
MATHEMATICAL MODELS FOR EXPRESSING THE OIL EXTRACTION AT SCREW PRESSES
the same thing happens when oil is expressed using screw presses, [12]. Vadke et al., [13], applied the Shirato model to a laboratory screw press and achieved relatively good results for the prediction of seed throughput and press cake residual oil, but only when the working conditions were very close to those of Shirato model.

Aqueous extraction of residual oil from sunflower
As it has been demonstrated for sunflower seeds that high oil recoveries of up to 85% can be reached through twin-screw extrusion-pressing without any solvent injection (Kartika et al., 2006), the
The results were compared to a single-screw lab-scale press. 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
- What is a professional sunflower seed oil press?
- The professional sunflower seed oil press is ZY24 (202-3) continuous oil extraction machine. In small and medium-sized vegetable oil plant, ZY24 (202-3) continuous pre-pressing machine is a popular equipment for pre-squeezing and leaching process.
- How much is a bag of sunflower worth in Zambia?
- Most farmers prefer to sell their sunflower as seeds and grain rather than process it because they receive sales income immediately. But now that Mrs. Kamuwikeni is adding value to her sunflower harvest, she is making twice the money she used to make. A bag of sunflower weighing 25 kilograms is sold at 150 Zambia Kwacha (about $6.60 US).
- How much does Naomi kamuwikeni sell a bag of sunflower?
- Mrs Kamuwikeni can sell a 25-kg bag of sunflower for 150 Zambia Kwacha ($6.60 US). Or she can process that bag into 10 litres of cooking oil and sell it for 430 Kwacha ($19 US). It¡¯s seven o¡¯clock in the morning and Naomi Kamuwikeni is quickly walking to the oil expeller at Gondar market. She is carrying sunflowers to process into oil.
- How much does a sunflower cake cost in Zambia?
- Another benefit is that she can collect a by-product called sunflower cake and sell this to sunflower cake vendors at 1.20 Zambia Kwacha (about $0.05 US) per kilogram. Each 25-kilogram bag of sunflower gives Mrs. Kamuwikeni 10 kilograms of sunflower cake.
