The equipment used to separate the oil from olive paste is crucial to the olive oil production process. This equipment can range from traditional stone mills and hydraulic presses to modern, continuous systems employing centrifuges and decanters. These systems typically involve a series of steps, including crushing and malaxation of the olives, followed by separation of the oil from the resulting paste and wastewater.
Efficient oil separation contributes significantly to the quality and yield of the final product. Modern methods offer advantages in terms of hygiene, processing speed, and automation, leading to higher production volumes and reduced labor costs. Historically, olive oil production relied on simple mechanical methods, evolving over centuries to incorporate technological advancements that maximize oil extraction and preserve its desirable characteristics. The evolution of these methods reflects the enduring importance of olive oil as a culinary staple and economic commodity.
