The diagram illustrates the process of olive oil production.
Overall, the process is divided into seven distinct steps, starting with olive harvesting and ending with the storage and sale of the finished product.
The first step in the production of olive oil is the manual harvesting of olives from trees, after which they are transported on a belt to be cleaned with cold water to remove any impurities, and then they are crushed with a machine to form a paste, which is then placed in bags with holes so that the oil can be extracted from the paste.
The next crucial step is to press the olive paste with a mechanical press to extract the oil and olive stones. The mixture of water and oil is then treated in a tank that is intended to keep the two substances apart. As the production process comes to an end, the pure olive oil is stored until being made available for purchase in stores.
