The decanter is integrated into the olive oil outlet and is designed to insulate the contact of the olive oil with the air. The olive oil coming out of the decanter firstly fills the pump oil transfer tank. When the tank is full it automatically actives and sends the olive oil to the filtration tank. No operators are needed for this operation. It is possible to see the outlet of the olive oil thanks to the plexiglass on the tank. Besides, visual and taste tests of the olive oil are performed from the sampling tap.
