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
he 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)
here 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
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.

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