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.
Mechanical Continuous Oil Expression from Oilseeds: A Review
The oil extraction by mechanical pressing is the most common method for continuous treatment of oleaginous seeds without solvent. Different types of presses can be used depending on the purpose (expeller, expander, and twin-screw extruder) and on the capacity range (3 kg h−1 to 150 t day−1). At the laboratory scale, many authors have highlighted the effect of operating parameters (screw
Box-Behnken design of response surface methodology was used for the study considering 80–95 g dehulled sunflower, 5–20 g wheat bran, and 6%–10% (w.b.) sample moisture while press head temperature was 50–90°C. Important oil expelling parameters viz. oil recovery, residual oil, free fatty acid, etc., was evaluated.

Influence of Grinding Degree and Screw Rotation Speed on Sunflower Oil
solutions [21–23]. Understanding the underlying physical changes during sunflower seed pressing is essential for optimizing the extraction process and achieving higher oil yields. Factors such as the seed moisture content, pressing temperature, and screw press design influence specific physical transformations.
Fig. 9 A and B show the different screws and set nozzles of the screw presses, and in Fig. 10 A–C, the sunflower cake at the exit of the screw presses. In cold pressing, the seed goes into a central hopper of the press, and is moved through one or more screws, crushed against a nozzle and screens to extract oil without heating the seed above a temperature of 50°C (120°F).
- Does a screw press machine affect oil yield of N sativa seeds?
- Deli et al. (2011) studied the effects of physical parameters of a screw press machine on oil yield of N. sativa seeds using a KOMET Screw Oil Expeller. Different nozzle size, extraction speed and diameter of shaft screw were applied in their study.
- Who developed a screw press for sunflower oil expeller?
- Bamgboye and Adejumo (2008) also developed and modified a screw press for sunflower oil expeller. Modh and Mevada (2011) designed and made improvement in some components of oil expeller machine and also carried out the thrust ball bearing analysis and results to compare with analytical results.
- What are the disadvantages of screw press expeller?
- Some major drawbacks of available screw press expeller were identified from this customer survey which includes poor oil extraction efficiency, heavyweight, high purchasing cost, difficulties in maintenance and cleaning mechanism etc.
