For many many years, going back to the ancient Greeks and Romans, people have used presses to extract olive oil from the olive, the press is used to separate the olive oil and vegetation water from the solid body of the olive. Once these two have been separated, a decanter is used to separate the oil from the water. In able to gain a fine olive oil, there is a process that must be used before the olive is pressed.
After the olive harvest has taken place, the olives are placed under a millstone or ground stone for thirty to forty minutes to ground them to a paste called olive paste. The olives are left under the stone for this amount of time to achieve the flavor they need and to form large olive oil drops. The aromas that the olive enzymes let out are also need to create a better aroma for the oil.
Once this process is over and the olives are converted into a paste, the past is spread onto fiber disks. Once fully and evenly spread onto the disks the paste is placed into the press machine. The press will then apply the necessary pressure needed to compact the past and percolate the oil forms and the water in the paste. Water is placed in the sides of the press to simplify the process of percolation.
When the pressing process is over the two liquids are placed in a traditional decanter to separate them, although this process can also be done using a vertical centrifuge. This process separates the two liquids a lot faster then when using a traditional decanter thus completing the process of olive oil extraction a lot quicker.
After the olive oil has been made and before restarting the process to make more, the materials used must be cleaned expertly to avoid any contamination to future oils caused by fermented paste from the olives that can get stuck on the disks and ground stones. Once cleaned the disk and ground stones undergo another examination to make sure that all excess pastes and oils have been removed.
The advantages of making olive oil using this traditional pressing method include a better grinding of the olive and easier to pomace as less water is added. But there are also disadvantages that include a difficult clean process, a lot more manual labor and a longer time space between harvesting the olives and pressing them.
