MECHANICAL CONTINUOUS OIL EXPRESSION FROM

Abstract: Oil can be obtained from an oil seed through mechanical methods or solvent extraction. Mechanical expression of oil involves the application of pressure (using hydraulic or screw presses) to force oil out of the oil bearing material. In solvent extraction, solvent such as hexane is usually applied to remove oil from the material.

Expeller pressing

Overview. An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Other materials used with an expeller press include (but are not limited to) meat by-products, synthetic rubber and animal feeds. Raw materials enter one side of the press and waste products exit the other side.
