Filtering versus decatting
Decanting is based on the difference in density between the two components (in this case the oil on one hand and the water with olive particles on the other), which causes them to remain at rest, both separating until the most dense in The bottom of the container containing them. In this way, we can empty the contents (ie, the oil) from above. <a href=”http://www.olicatessen.com/wp-content/uploads/2017/02/111_decantacio1-e1487155708498.jpg”><img src=”http://www.olicatessen.com/wp-content/uploads/2017/02/111_decantacio1-e1487155708498-300×173.jpg” alt=”decantacio” width=”300″ height=”173″ class=”size-medium wp-image-3100″ /></a> dipòsit decantació, deposito de decantación
Definition (Wikipedia): In the sedimentation separates a solid or liquid more dense of another fluid less dense and that therefore occupies the part superior of the mixture.
For example, if a certain (reduced) quantity of a water-oil emulsion is to be separated, it can be charged into a separating funnel, which after standing for a sufficient time for a clear separation of the two substances can be separated into Two fractions. To do this, the lower spigot is opened and the more dense liquid (in this case the water) is allowed to flow out, and just when the interface of both liquids approaches the valve, the flow is cut off. At this time the water is collected in a vessel, and the oil inside the separating funnel
Filtration Operation that consists of removing the solid waste that could have been suspended in the oil. (By Mercacei: http://www.mercacei.com/seccion/77/dictionary-del-sector/)
Filtration: Remove the suspended particles from the oil to avoid the cloudy appearance before the packaging.
Filtration is a technique, technological process or unitary separation operation, whereby a mixture of solids and fluids, gas or liquid is passed through a porous medium or filter medium which may form part of a device called a filter, Where most of the solid component (s) of the mixture is retained.
This technique, although it is true that it is faster and guarantees the elimination of water and particles of the olive, is also more aggressive, because in the filter, polyphenols are lost and non-recyclable waste is generated.
