How it is prepared


The decantation process consists in separating the olive paste in oil, mill waste water and marc; it can be carried out in two or three phases. Through the decantation in two phases, the mill waste water is obtained. This type of process does not require the addition of water to the decanter: this allows saving both drinking water and energy. On the other hand, a very humid, difficult to manipulate marc is obtained. Through the decantation in three phases, the marc obtained has an approximate humidity of 50%, whereas the process does require the addition of hot water, but gives, in return, a dry marc, easy to manipulate. The marc which is unloaded from the decanter is collected in a transporting worm, while the oil and the mill waste water pass through vibrating sieves that retain the solid suspended particles. The obtained oil is transported through a pump from the vibrating filter to a vertical centrifuge for an automatic cleaning. Here, by means of centrifugal force, the cleaning process starts, during which humidity, fine solids and impurities are removed. The oil remains dissolved so that it can be moved to the deposits. The clean olive oil is stored in tanks of stainless steel. To prevent rancidity or haze, the deposits must be made of an inert, opaque and waterproof material, unable to absorb odours. Besides, the temperature will be maintained around 15º C.
