The exploitation of the LEOPARD multi-phase decanter from Pieralisi gives our oil mill high standard in matter of innovation, competitiveness and respect for the environment:
Superior quality of the extracted oil without water addition
One of the highest yield on the market
Reduced consumption of energy and water
technology of the multi-phase decanter has been developed in order to
avoid the addition of water to the olive paste during the extraction
process. As a consequence, it produces as side products a dehydrated pomace suitable for pellet production and the olive pulp named patè,
ideal as food supplement or for sheep feeding.
All this allows the reduction of
the environmental impact of the oil industry as well as an enriched
polyphenol content in the extra virgin olive oil obtained. In fact,
these antioxidants are water-soluble and usually washed off in the
extraction with water, but in this case they are retained in the oil

Olive oil extraction process
In our oil mill the superior quality extra virgin olive oil is obtained by cold pressing and it undergoes only mechanical methods, ensuring the preservation of its properties such as color, smell and taste.
The olive oil extraction process in an oil mill equipped with a modern continuous cycles system like ours is divided in five steps.
Once the oil drops extracted from the pulp have coalesced, the olive paste is centrifuged. Thanks to the latest generation Leopard multi-phase decanter, the olive paste is separated into three different fractions according to their specific weight: crude oil, patè and pomace.
The waste is represented by the patè (skins and part of the pulp dispersed in the vegetation water of the olives) and pomace (wet solid fraction containing pulp and kernels).
The final step involves the removal of the residual vegetation water from crude olive oil.
The separation is carried out by mean of a vertical centrifugal separator, that rotates at about 6000-6500 rpm.
The crude oil is inserted from above and it is purified from water and small solid impurities because of their different specific weigth.
