Sunflower Seed Preparation and Oil Extraction
Sunflower is crushed for oil recovery via one of two process methods, hard pressing or prepress solvent extraction. Hard pressing relies upon exerting high pressure on the prepared seed to separate oil from the solids fraction, historically recovering about 25% oil from the seed. Prepress solvent extraction relies on exerting medium pressure on
Sunflower oil production has the following manufacturing processes: cleaning of the seeds, grinding of the seeds, pressing and extraction of crude oil from these seeds and then further refining the oil obtained before packaging. A volatile hydrocarbon like hexane is used as a solvent to extract the oil. Cleaning.
Expeller Pressed Sunflower Oil vs Solvent Extraction Methods
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.
The residual oil rate of sunflower seed cake after pressing is about 6%. After pre-pressing, part of the sunflower oil and sunflower seed cake will be obtained. 2, SUNFLOWER SEED CAKE SOLVENT EXTRACTION PROCESS.

From Seed to Oil: Unveiling the Sunflower Oil Extraction Process
The process of extracting sunflower oil involves various steps, such as: cleaning. dehulling. cooking. pressing. refining. The extraction method used depends on the desired quality and yield of the oil: Mechanical pressing is a popular method that involves squeezing the seeds using a machine to extract the oil.
The extraction mixture consisted of approximately 10.0 ± 0.1 g of sunflower collets and 180 mL of ethanol (95%, bp 78 °C), corresponding to a collet-to-solvent ratio of 1:18 (g/mL). The agitation rate was kept constant in all experiments, being sufficient to maintain a well-mixed fluid and the particles in suspension.
A Step-by-Step Guide on How Sunflower Oil is Made
Solvent extraction is the part of the sunflower oil making process in which almost every last drop of oil is extracted from the sunflower seeds. Hexane is the most widely used solvent for this. The process begins with the pouring of hexane over the leftover cake from expeller pressing.
The solvent extraction process has the advantage of a much higher oil yield (
The sunflower seeds oil extraction: the mechanism
Oil effective diffusivities were 9.94 10 À10 at 50 C and 3.11 10 À9 m 2 /s at 60 C. From the point of view of the quality of the obtained products, this work demonstrated the feasibility of using ethanol as an alternative solvent to hexane in the oil extraction from sunflower collets.
In addition, oil extraction yield increased as screw rotation speed and feed rate were simultaneously increased to Q S /S S ratio of 0.2. Highest oil extraction yield (98%) with best cake meal quality (residual oil content lower than 3%) was obtained under screw rotation speed of 185 rpm, feed rate of 30 kg/h, and solvent-to-solid ratio of 0.55
