A press developed at MIT's D-Lab, for example, is capable of exerting 800–1,000psi to extract peanut oil. [2] Industrial machines for extracting oil mechanically are call expellers. Many expellers add heat and pressure, in order to increase the amount of oil extracted. If the temperature does not exceed 120 °F, the oil can be called "cold ...
Many oils are marketed as first cold pressed or cold extraction. "Cold" means no heat is added during extraction. "Pressed" means that the olives are crushed in a mill to extract the oil. [19] In the EU, these designations are regulated by Article 5 of Commission Regulation (EC) No 1019/2002 of 13 June 2002 on marketing standards for olive oil.
In many parts of the world, such as Australia, producers using centrifugal extraction still label their products as Cold Pressed. First cold pressed means "that the fruit of the olive was crushed exactly one time – i.e., the first press. The cold refers to the temperature range of the fruit at the time it is crushed". [78]

A kitchen hood in a small apartment. A kitchen hood, exhaust hood, hood fan, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. [1]

In the processing of edible oils, the oil is heated under vacuum to near the smoke point or to about 232 °C (450 °F), [33] and water is introduced at the bottom of the oil. The water immediately is converted to steam, which bubbles through the oil, carrying with it any chemicals which are water-soluble.
Cooking oil (also known as edible oil) is a plant or animal liquid fat used in frying, baking, and other types of cooking. Oil allows higher cooking temperatures than water, making cooking faster and more flavorful, while likewise distributing heat, reducing burning and uneven cooking. It sometimes imparts its own flavor.
