  • the device object of the present patent application allows to carry out both the malaxation step and the centrifugation step of the olive pulp to obtain an olive oil at home or wherever it is needed and whenever the oil is needed.
  • Olive oil is obtained by pressing olives through mechanical or physical means, therefore without the need of any chemical intervention.
  • the conventional method involves crushing the olives in stone mills, thereby obtaining a paste of crushed olives, malaxing the paste to break up the emulsions, spreading the malaxed paste on fibre disks which are stacked on top of each other alternating disk and crushed and malaxed olive paste, pressing the disks stacked on top of each other on which the paste was distributed to expel the oil.
  • Olive oil is a natural product that deteriorates over time. When it is just produced, it is rich in all its organoleptic properties, which are lost over time.
  • EP2796077A1 discloses an oil extraction device, the oil extraction device comprising: a malaxation and centrifugation vessel for malaxing and centrifuging milled olives having a hole in the lowest part of the malaxation and centrifugation vessel.
  • EP2796077A1 requires an additional container for the liquid produced during the centrifugation step, wherein a decanting tank is provided for separating oil from water.

Lastly, the oil falls onto a tray through a valve situated at the lower part of the removable container.
  • the device described in WO2017/051043A1 has several drawbacks.
  • said device is made to grind fresh olives and does not provide for the thawing step of the olive paste, whereby, even in the thawing step, the blades would spin in the frozen olive paste, thus risking breaking down.

  • said electronics operates the power of the motor by increasing it if the resistance of the pulp tends to decrease the number of revolutions by bringing them back to the desired ranges.
  • Another feature is that in the cap or in the containing drum or in the base there are a heating assembly and a fan.
  • the heating assembly is an electrical resistance provided with a temperature sensor.
