Oil expeller machines are a core part of the edible oil industry in India. They are widely used for extracting oil from seeds such as mustard, groundnut, coconut, sunflower, soybean, canola, and more. This article explains what an oil expeller is, how an oil expeller machine works, how it is manufactured, and what expeller-pressed oils really mean, from a professional and practical industry perspective.

What Is an Oil Expeller?

An oil expeller is a mechanical device used to extract oil from oilseeds by applying continuous pressure. Unlike solvent extraction methods, an oil expeller does not use chemicals. The oil is released purely through mechanical force, making it suitable for traditional, small, and medium-scale oil mills.

Oil expellers are commonly used to produce expeller-pressed oils that retain natural characteristics and are widely accepted in Indian and international markets.

At Rajiv Engineering Works, oil expellers are designed keeping Indian operating conditions in mind, focusing on durability, efficiency, and consistent oil output.
