A novel oil extraction process as such, including a first pressing step using an extruder configuration based on the one optimized by Kartika et al. (2005, 2006) for the pressing of sunflower seeds, and a subsequent second passage of the press cake involving the green solvent extraction of its residual oil, was considered by several researchers

Recently, however, the word „expeller“ has come to mean homogeneous pressing residues, while „oil cake“ is used to describe mixed pressing residues. Grain size: diameter 20 – 40 mm Oil content: 1.5 – 7.0% [1] Quality / Duration of storage Product intended for shipping must be adequately matured.

Production Process for Sunflower Seed Oil; Expeller pressed sunflower oil and solvent extraction methods are two common production processing for sunflower oil. Using the pressing method typically results in an oil residue rate of around 7%, whereas solvent extraction can reduce the oil residue rate to about 1%. It's worth noting that solvent

Why Is There A Lot Of Oil Residue In The Oil Squeezed Out By

• Usage: sunflower oil
• Voltage: 380
• Power (W): Standard
• Certification: ISO9001
• Weight: Standard
• Dimension (L*W) *H): Standard

There are a lot of oil residues in the oil squeezed out by the oil press because the oil cracks of the press bar are blocked by the oil residues or crushed pieces, or the press bar is too tightly packed. At this time, the oil residue should be cleaned up in time, and the pressing strips should be reinstalled.

Pressing: preheated sunflower seeds are fed into a mechanical oil press. The pressure and heat created by the press force the oil to be squeezed out of the seeds. Repeating the process of heating (reheating) raw materials and final pressing of the oil. Separation: The oil and solid residue, known as the slurry, are then separated.

Sunflower seed is one of the eight major oil crops and the fourth largest oil crop in the world after palm, soybean and rapeseed. Sunflower oil contains up to 48.3%-74.0% linoleic acid and is rich in vitamin E, sterols and other bioactive components, which has high nutritional value. In recent years, the process of frying sunflower seeds and then pressing them to produce concentrated sunflower oil has been popularized and applied.

When oleic sunflower oil is expressed, a longer reversed pitch screw improves oil yield, which can rise 80% in the optimized operating conditions (Lacaze-Dufaure et al., 1999a). When two reversed pitch screws are used, the oil yield increases with the distance between them and with the decrease of the screw pitch (Aindonesiaa Kartika et al., 2005a).

Expeller pressing is a mechanical extraction method that utilizes a screw-type mechanism to extract oil from sunflower seeds. This approach is favored for its simplicity and minimal use of chemicals. The seed is fed into the expeller machine, where it is crushed and heated, releasing the oil while leaving residue in the form of cake or meal.

Expeller pressed sunflower oil and solvent extraction methods are two common production processing for sunflower oil. Using the pressing method typically results in an oil residue rate of around 7%, whereas solvent extraction can reduce the oil residue rate to about 1%. It's worth noting that solvent extraction machine is costlier.
