How Do You Get Olive Oil From Olives?

By Brandino Z Borgattelli

Using a traditional press to extract olive oil from olives has been used for hundreds of years. This process consists of extracting the oil and water from the olive paste. A complete process is needed in able to make olive oil, which once finished with the pressing process; it must also be put through a decanter in order to separate the vegetation water from the olive oil itself. Here is the full process that is needed:

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.

After the necessary time the olive paste is removed from the millstones or ground stones and put onto special disks called fiber disks. The paste must be spread over the disks and completely cover it. They are then placed into the press, piled on top of each other. The machine will then press the paste and begin to compact it so the oils will start to percolate. So the percolation is easier water is poured down the sides of the press.

After the pressing process is over the liquids are removed from the presser and taken to a separate machine called a decanter. The decanter is used to remove the excess water from the olive oil, leaving a pure olive oil. There is another process that can be used to separate the water from the oils, it is called vertical centrifuge and is normally a lot faster than using a decanter.

Once the extraction process has been fully completed, the cleaning process begins. This process has to be done thoroughly because if not the remaining past will begin to ferment on the millstones and disks causing other oils to get contaminated and change the taste of the oil completely. Every time new oil is to be made, a complete check that the press and millstones are completely clean must be done.

There are both advantages and disadvantages when using this method of extraction to make olive oil. The advantages are that there is a better grinding of the olives and due to less water usage; the oil is pomaced a lot easier. The difficult cleaning process, a wider time between the harvest and the pressing of the olives and the amount of manual labor are some of the disadvantages.
