Barigelli machines for those people serious about producing quality olive oil


All C5.10 models feature:
  • Supporting frame on vibration dampers for vibration damping
  • Device for the continuous discharge of solid material dried (scraper)
  • Drum drive via belt drive
  • Digital Tachometer for drum speed display

The decanter is a horizontal centrifuge used to separate the olive oil from the water and solid phases of the olive paste. Two main types of decanters are used in commercial olive oil production:
  • Two-phase decanter: This system does not require the addition of water, resulting in denser pomace and higher retention of phenolic compounds. The absence of added water enhances the oil’s antioxidant properties and produces oils with stronger sensory characteristics such as bitterness and pungency.
  • Three-phase decanter: This method involves adding water during the centrifugation process. While this dilutes phenolic compounds, it allows for the retention of tocopherols and carotenoids, which are crucial for oil stability and nutritional value. Three-phase systems produce oils with more pronounced fruity notes, but generally lower antioxidant content compared to two-phase systems.

A critical factor in the decanter’s performance is Dn, or the differential speed between the drum and the screw. The drum rotates at a high speed to generate centrifugal force, while the screw moves at a different speed to transport the solid residues (pomace) out of the decanter. The speed difference between these components directly impacts the efficiency of separation and the quality of the oil:
  • Higher Dn (e.g. Dn16): A greater difference in speed leads to faster separation of the olive oil from the paste, reducing the oil’s exposure to oxidation. However, faster separation can result in less time for the extraction of phenolic compounds and other antioxidants from the paste.
  • Lower Dn (e.g. Dn11): A smaller differential speed slows down the separation process, allowing for more thorough extraction of phenolic compounds but potentially increasing the risk of oxidation due to prolonged contact with oxygen and water.
