Kind of product:
The
olives collections come from lands of our associates, locate
for the major quantities around Vetralla Common .The
remaining product , approximately 10 %, is located around Viterbo
Common.The extraction of oil happens through the preparation
of a paste of olives obtained using stone grinders and
subsequently pressed to cold temperature using hydraulic presse.
The traditional job process
of olives.
The traditional job
porcess of the olives
allows to obtain the best EXTRAVIRGIN OLIVE OIL, which being obtainable only with the "cold
pressure" (with grinders and presses) it this process is
the only one that leave intact the
content of vitamins, and permit to maintains the olive organic property
unchanged and it permit also to have a product more assimilable and much
delicious. The
oleic acid content in olive oil don't permit to go up the
cholesterol rate of who consumes it.
This technique today is
little bit used because it has higher
costs than the modern lines of extraction. The job
process
happen for single stock of product , directly follow on each
job passage directly from the
Associate, that holds a part of production for familiary use. The Cooperative systematically executes controls
on the entire cycle production, engaging itself for commercialization
only Extravirgin olive oil that corresponds to best quality criteria and
particularly integrity.
The
olives collection.
The collection of the olives happens
between the end of October and the first days of the new year,
and can be made with various methodologies: hand made
collection "brucatura" - mechanical collection - with machine
named "scuotitori" - that knocking down or
collection to earth. The most traditional it's hand made
collection , that consists in detaching manually the olives
from coppers: this is an optimal system, the best one from the
point of view of quality, because it permit to collect the
olives to the just degree of maturation and l without any damage to the fruit
and the plant. Our Associates they are still using this
collection mode, even if its cost is highest for the
number of people
employes for olives collection, infact this collection determine
the high cost for the
total cultivation.
Olives transportation.
The transport
covers an importat rule for a good oil production ,
if it's done by alimony boxes, the olives property remain
totally free from bruise and without any lesion. For this reason it is absolutely
indicate that the transport of the olives pressate can't
make with bags,
but only carried out in plastic alimony boxes.
The olives cleaning.
Before the "molitura
process" it is important the clean of the olives:
this happens by machinery called (defogliatrici) in which
happen for ventilation power, the olives cleaning from eventual presence
of stranger bodies on the surface of the fruit. This important
phase don't permit to the the oil prodution to assume anomalous colors
bad taste.
The molitura
This s is the
operation that serves to transform the olives to be one homogenous paste to subject subsequently to
"spremitura". This
operation is carried out with use of grinders, constituted by large "wheels" of granito (traditionally
called grinder).After "molitura" it is very important, to
facilitate the spremitura, the delicate continuous
remix of the olive paste ("gramolatura"):
thanks to this operation the oil, under shape of drips permit
to obtain form small oil particles (5-6 micron of diameter),
some particles
more bigger , and therefore more easy to drain.
The must pressure.
The pressure of olive must is
completed with hydraulic presses that generates pressures at 400
atmospheres just to obtain from the olive paste an oleic must.
The paste of olives comes therefore disposed in thin
layers from leaking diaphragms, called "FISCOLI", the process form,
is one
over the other just to arrive to construct an"open tower". Finished to the jam and the
drips of oleic must, the solid parts that remain (said
SANSE) it will be transported to specialized farm. Oleic must with the jam of the olive paste, for
arrive to Extravirgin olie need to be cleaned (separated) from the WATER OF
VEGETATION, and eventual heavy particles. A long time ago the separation
process was made by SETTLING method for the gravity
power the oil ends in order to float on the water.
Today this system has been replaced by the SEPARATION WITH
CENTRIFUGE, arranges faster and precise. The methodology is done by vertical centrifugator,
called SEPARATORS, which take advantage of the
principle classic of the separation for centrifuge of a liquid
composed by various elements for specific weight: for physical
effect lightest the heavier materials are offered to the outside and
to the inside. After to be passed from a series of cones that withhold the impurità,
comes to being collected in the inner tube and starting on the containers.
