This equipment mechanically extracts oil from seeds, nuts, or fruits without introducing external heat. A hydraulic press or an expeller press is commonly used to exert significant pressure, squeezing the oil out while maintaining lower temperatures than traditional methods. This process typically yields higher quality oil with a richer flavor profile.
The lower processing temperature preserves delicate aromas, nutrients, and antioxidants, resulting in a product superior to oils extracted using heat. This method also avoids the use of chemical solvents, yielding a purer, healthier end product. Historically, similar techniques existed for centuries, but modern advancements have led to increased efficiency and scalability in oil production, making this approach accessible for both artisanal and industrial applications.
