Description
An oil expeller, also known as an oil press or oilseed press, is a mechanical device used to extract oil from various oil-rich seeds or nuts. It works by applying mechanical pressure to the seeds or nuts to squeeze out the oil.Here's how an oil expeller typically workFeeding: The seeds or nuts are fed into the expeller through a hopper.Crushing: Inside the expeller, the seeds or nuts are crushed by a rotating screw or shaft. This mechanical action breaks down the seeds or nuts and releases the oil.Pressing: As the seeds or nuts are crushed, the oil is squeezed out through small openings or gaps in the expeller's barrel. The pressure applied by the screw or shaft helps to force the oil out.Separation: The extracted oil flows out of the expeller, while the solid residue, known as oil cake or meal, is expelled from the other end.
