Mills in Altoaragón - aceitero


Buera is situated not far from Alquézar. From Barbastro take the road that longs the Río Vero and passes through Castillazuelo, Pozán and Huerta de Vero. At some point Buera is signposted to the right. Drop your vehicle at the designated spot at the entrance of the village. From there it is only a short walk to the Torno which is signposted. The mill is restored and a museum now. Visits are guided, most interesting, and include a tasting of some kinds of olive oil.

(1) Torno de Buera - entrance
The main exhibition shows the situation in the first half of the 20th century. First a stationary Motor Vellino Type CZ (6) was installed and somewhat later, in 1927, a hidraulic press (5) and a batidora (3).

Before that time the miller had to work with a huge prensa de viga y quintal, a cantilever press. It was a slow process requiring several hard working people and with the risk of a fracture of the beams always present. The original press did not survive, but a life size replica has been built and is on display. This type was also used in e.g. Aguinalíu, Castarlenas.

(2) Exhibition of the main tools: torno, oil pump, mixer, hydraulic press (r -> l)

(3) Batidora (mixer)

(4) Bomba (oil pump)
There was a diesel engine and later on an elec­trical one so the work in the mill could be mecha­nised. Belt and cog wheels drove the oil pump and the mill stone (2) and a batidora was introduced.

A batidora (3) is a device which stirs the mash of olives and heats it up to the right temperature for fur­ther processing. It means a considerable reduction of work for the miller.

An endless screw gobbles up the output of the mill (3r) and lifts the paste up to the top of the contrap­tion. The mash is heated and homogenized and then released at the bottom (3l) where it waits, ready to be scooped between the capachos, or esteras, which are double layered discs originally woven from the grass Stipa tenacissima but are nowadays made from syn­thetic fibers.

(5) Prensa hidráulica (hydraulic press)

(6) Motor Vellino Tipo CZ — cooling system removed
The esteras are stacked into a vagoneta (notice the wheels) which was then pushed into the press (5). The press comes from Talleres de Baró in Tortosa a company founded in 1886 by Francisco Baró Ginestar. Baró invented several tricks to improve the yield of its tools. Other Baró installa­tions can be seen in Angüés and in Castillazuelo.
Motores Vellino was once a very popular brand of stationary engine. We have seen other types of Vellino in Palo and Banastón where I give a short history of the brand.
