Actual methods for obtaining vegetable oil from oilseeds
Actual methods for obtaining vegetable oil from oilseeds. Vegetable oils are an important component for both food (for feeding, margarine and canned food industry, bakery, confectionery) and for non-food industry (production of detergents, paints, special varnishes, fatty acids, pharmaceuticals and cosmetics products, and painting).

Methods of Extraction for Vegetable (Carrier) Oils
Methods of Extraction for Vegetable (Carrier) Oils Cold Pressed or Cold Expeller Pressed: Cold pressed oils, also known as cold expeller pressed oils , have been mechanically pressed from the fatty portions of the botanical while ensuring that the maximum temperature (caused by friction) does not exceed 120 degrees.
Solvent extraction is a chemical oil extraction method to process oil out from vegetables, oilseeds and nuts by solvent, and Hexane is the preferred choice. Industrial oil processing for the edible oil generally involves the solvent extraction step which may or may not be preceded by pressing.

To extract isopropanol, four different type of vegetable oil have been used. Since most of the vegetable oils have similar properties so they can be used as a
Comparing with pressing method, solvent extraction method is more mechanized and the whole line is automatic to working. So operators needed in edible oil solvent extraction plant is much less than thant in edible oil pressing plant. Meanwhile, energy consumption for solvent extraction method is also much less than pressing method. 2.

Oil separation by extraction - Gustav Heess
During extraction, a solvent - normally food grade n-hexane - is used to separate the vegetable oil from cellular material. In order to ensure that the solvent enjoys unobstructed access to the interior of the seeds, the cell walls need to be broken down and diffusion pathways need, at the same time, to be kept short.

Mechanical Extraction Processing Technology for Biodiesel
Chemical extraction uses a solvent to remove the remaining oil that mechanical press cannot. Chemical, mechanical, and solvent extraction are terms accepted and understood by the industry. Small biodiesel businesses will likely extract oil from seeds using a mechanical method – a press that squeezes the oil out – rather than a chemical method, which is expensive and complicated.
