Etymology
The term 'expeller' originates from the verb 'expel', which means to force out or release. The use of the word in the context of oil extraction dates back to the early 19th century when mechanical devices were developed for more efficient extraction of oils from various seeds. These machines employed mechanical pressure rather than chemical processes, distinguishing them from solvent extraction methods. The technology has evolved significantly over the years, with modern expellers designed for enhanced efficiency and yield. The food industry has adopted expellers to align with growing consumer demands for natural and minimally processed oils, thus ensuring the expeller remains relevant in contemporary oil production.
