OILPRESS
Expeller pressing (also called oil pressing) is a mechanical method for extracting oil from raw materials. The raw materials are squeezed under high pressure in a single step. When used for the extraction of food oils, typical raw materials are nuts, seeds and algae, which are supplied to the press in a continuous feed. As the raw material is pressed, friction causes it to heat. In the case of harder nuts, which require higher pressure, the material temperature can exceed 120 °F (49 °C). "Expeller" is a trademarked term of Anderson International Corporation since 1900, although it has become genericized, is often confused with screw press equipment in general, and does not indicate whether oil extraction is done hot or cold.
