Oil extraction machines are equipment used to extract edible and industrial oils from seeds, nuts, and other oil-rich materials such as mustard, sunflower, sesame, and soybean.

The process begins with cleaning and crushing, where raw materials are prepared by removing impurities and breaking them into smaller pieces. Then, the material is fed into a pressing machine (expeller) that applies high pressure to squeeze out the oil.

In some systems, solvent extraction is also used to obtain maximum oil yield from the raw material. After extraction, the oil is filtered and refined to remove unwanted particles and improve quality.

These machines are widely used in the food and agro-processing industry and are related to Food Processing Technology.

Oil extraction machines improve efficiency, reduce manual labor, and support large-scale production of edible oils for commercial use.
