An oil extraction machine, also called an oil press or expeller, uses high pressure and heat to “squeeze” the oils out of a plant product. Those products — including seeds, nuts, vegetables, fruits and leafy plants — release their oils through this mechanical process, which is often done without adding any chemicals.The original oil expeller press was invented in the late 1800s by Anderson International's founder, Valerius D. Anderson. This patented mechanical screw press design was a radical departure from hydraulic presses used at the time.The Dutch, or stamper, press invented in the 17th century was used almost exclusively in Europe for pressing oilseeds until the early part of the 19th century, when the hydraulic press was developed.

Hydraulic oil press machine is an oil extraction machine that combines the traditional oil pressing method and modern oil extraction technology. The whole operation process is very convenient and easy. The pretreated oilseeds are loaded into the cylinder for oil pressing.Oil rigs and oil platforms are used to drill long holes into the earth to create an oil well and extract petroleum. After extraction, oil is refined to make gasoline and other products such as tires and refrigerators.Screw oil press is a compact-structured oil extrusion machine used for extracting edible oil from more than twenty kinds of oilseeds such as peanut, soybean, flaxseed, sunflower seed, rapeseed, etc.
