Extracting oils from olives using a press is one of the oldest ways to make olive oil, dating back over hundreds of years to the ancient Greeks. A simple process that is undergone using an olive press. But before the press is used there are certain processes that must be undergone first. Once pressed the liquid is put into a decanter so that the liquids can be separated. Let us take a closer look at the complete process:
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.
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.
Every time the process of extracting oil from the olives all of the machines must be thoroughly cleaned and disinfected. This is because any paste or oils left on the machines can ferment and therefore contaminate any new oils that will be done in the future. After the cleaning is finished, a final inspection will take place to make sure they are fully disinfected.
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. - 24553
