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
The positive impact of high temperatures has been observed in the pressing of sunflower seeds, where an oil extraction efficiency of 66% was obtained at 80°C, whereas 70% was obtained at 120°C
Recent industrials extraction of plants seeds oil used in the
This study aimed to assess the oil’s fatty acid composition and total tocopherol content. GC, GC/FID, and HPLC were used to analyze the fatty acid composition and concentration of total tocopherols. Compared to hexane/isopropanol extraction (8.3 2.7%), pumpkin seed oil obtained using Sc-CO2 extraction had a maximum yield of 24.3 0.4%.
Dehulled se are sflaked from dehulled sunflower se with d atwin,crew pr iss to 0.35 mm to rupture cell structures and free the oil, highly efficient. steam-cooked and partially dried, then expressed at 80-105°C and 4-7% moisture until 15-18% oil remains.

Research on mechanical‐structure properties during sunflower
A self-developed in-situ observation test rig and the FEM method were used to research the sunflower seed extrusion-structural damage evolution during extrusion-extraction. The research method can be used for better modeling and understanding the seed structural-mechanical and oil output property, leading to better oil extraction.

Supercritical extraction of sunflower seed oil: Experimental
Stahl et al. [3] measured the solubility of sunflower seed oil in CO 2 at various pressure values (in the range between 150 and 700 bar) and at a temperature of 40 °C; the authors [3] performed extractions with hexane at atmospheric pressure and with CO 2 in the pressure range between 250 and 350 bar, obtaining an oil yield (kg oil /kg seeds
exports sunflower oil to over than 100 countries of the world, which requires more efficient technologies for its production for the purpose of providing with world demand. For today, there are two methods of extracting oil plant raw materials: press and extraction. The advantage of the extraction method is the high degree of oil extraction of
A new twin-screw press design for oil extraction of dehulled
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.
Experimentally we investigated the kinetics of extraction of oil from shredding sunflower seeds n-hexane (t = 69 ° C) in Soklet apparatus for different mean grain diameters d aver = 0.7 mm, daver = 0.5 mm, daver = 0.25 mm. The research results showed that this process passes by a mixed mechanism (outer- and intra-diffusion mechanism).
