In the receptical you can see as oil appears on the surface, floating on the pastea.
The olive bulk is distribuited over the “capachos” (special esparto containers) in order to give a uniform pressing.
We put one “capacho” over the other with the olive bulk and when they get the maximum height it is time to put them into the hydraulic press.
It´s surprising to see how oil floats in the same light truck before entering the press.
The Oily Must that comes from the press goes to these deposit wells.This liquid is made up of vegetable water from the olive itself (alpechin) and oil. They are separated due to the difference in density: Oil 0,916 / Alpechin 1,052 . The result is that the oil floats because it is lighter and water stays at the bottom. This is due to the difference in density.
Experiment: We will need ½ glass of water and some oil. In the glass of water we add some oil, enough oil to cover all the surface. We will try to mix them using a small spoon and stirring well. Once this is done, let the mixture go down and see how the oil and the water separate completely.
