The diagram depicts the process of the oil production, outlining various stages involved.
Overall, it is evident that there are two main phases. The first one consists of three steps, from picking leaves to making two different products; the second one includes four more processes before olive oil ends up on the shelves of shops and storages.
Initially, olive leaves should be manually harvested, which is followed by rinsing in cold water to remove impurities. Then, they are subjected to smashing in a big container to produce olive paste and olive stones as a side product.
Moving to the final phase, olive paste is placed in bags with holes. The following stage is to press the paste in a large container until it becomes liquid. The next step deals with getting pure olive oil, separating it from water. Finally, the product may be transported to storage facilities and shops for sale.
