The production of olive oil begins with the picking of olives, continues with their transport and ends up with their processing in olive mills. After harvesting, any remaining leaves are removed; the olives are washed, and are ground into a pulp using a revolving mill, usually constructed with stainless steel or granite. The entire olive, including the pit, is pressed until it becomes a paste, which is then whipped, adding water. Next comes the phase to separate solid from liquid, either by the traditional process, or by a continuous system 3-phase centrifuge process.

 

The main Olive Solid Residues which are generated during the olive oil production is named “Virgin olive pomace”: 

 

The residual paste after the olive oil extraction. It is constituted from a mixture of olive pit/stone, olive pulp & skin, as well as pomace olive oil plus the water added in the olive mills. 

 

The moisture content is between 25-30% in the pressing system, and 45-60% in 3-phase centrifugal systems. It’s used as solid biomass fuel, or it can be transformed into Charcoal. Using Centrifugal machine, pits can be separated from the pulp and it can be used for Industrial combustion or it can be transformed into powder for Industrial, Pharmaceutical or Cosmetics industries.
