GIUBILEO - cold extractor
Giubileo (cold extractor)
Giubileo, synthesis of tradition and vanguard technology
in a machine that is unique in its kind.
More than twenty years after the first patented refiner for fruit
and tomato Butterfly and after hundreds of successful
installations all over the world, we, at Rossi & Catelli have
accepted the challenge of a global market which demands
more versatility, more reliability and higher performances: our
reply is Giubileo the newly designed refining unit which
distinguishes itself among all existing units on the market, both
from the technological and manufacturing point of view.
Designed in every detail to grant higher performances and
maximum functionality, Giubileo represents all Rossi & Catelli’s
know-how and, thanks to its versatility, allows to process a
wide range of products – whole or destoned fruit and various
kinds of vegetables – to obtain finished products capable of
meeting the strictest quality parameters.
The Genius in Food Processing
Versatility which has A Copernican
no fear of comparison revolution
Versatility means to convert in a quick,
effective and economic way one’s
extractor into a refiner or a press with no
need of returning the unit to the
manufacturer nor long preparation times.
This not only means being able to process
pears from October to November, apples
in January and so on, but also to
Cold-Break process tomatoes in July
and Hot-Break process tomatoes in
August.
In order to assure top performances in
such a delicate and strategic point of the
process, as the refining is, we wanted to
put in the middle of our universe those
who better than anybody else know
product characteristics as well as
processing cycle in its complexity:
the machine users.
As a matter of fact, with Giubileo, the
protagonist no longer is the manufacturer,
but the user who, based on the processed
product as well as on specifications, can
act on a wide range of different
parameters, such as rotor rotation speed,
dimension of screen holes and, patented
absolute novelty, paddle angle of attack.

Technical features
Giubileo shows the new and original
design of a platform technologically in the
van, which is the beating heart of the
machine onto which a wide range of
customized solutions can be fitted, and
meet various production requirements.
The platform includes:
• The frame: made in AISI 304 stainless
steel and fitted with connections for
handling and rails for moving back of
shaft support and rotor during
maintenance.
by a manual butterfly valve installed
beside the body and acts both on
screens and on the rotor.
• The rotor: made in AISI 304 stainless
steel and fitted with paddles micro
casted in high resistant alloy.
Paddle angle of attack can be adjusted
and allows to control product residence
time inside the screens and to have the
machine run in both directions.
• The shaft support: made in AISI 304
stainless steel and placed on bronze
sliding blocks allowing the simultaneous
extraction of support, motor and rotor,
thus making any maintenance
intervention easy; it is also fitted with
a practical plug for oil charging, as well
as with a sight glass to check oil level.
• The motorized system for rotor
removal: allows an easy and safe
maintenance at the end of processing
season.
A motoreducer drives a worm screw
acting on a nut thread fixed on to the
structure to be moved back; the
engagement between these two
components allows to move them.
The system is supported by two ball
bearing devices placed on the
machine frame.
• The body: made in AISI 304 stainless
steel and fitted with connections for
washing circuit and adjusting devices
allowing a perfect aligning between
screen and rotor.
The washing circuit can be controlled
• The driving group: composed by the
motor, the joint and the motor support
and can be customized according to
various needs and various powers, by
choosing among the traditional IEC
motors and the U.S. NEMA ones:

• The “Extractor” product feeder:
installed on the machine cover and allows
to feed whole fruit without stones (pears,
apples, kiwis, tomatoes) or destoned fruit,
such as peaches and apricots.
It consists of a screw, driven by a 4.5 kW
gear-motor, which feeds a pre-impeller
integral with the rotor, fitted with sliding
blades. Sliced product is then softened
and reduced to a puree by means of a
pre-screen integral with the rotor, and
then enters the screens where it is refined.

The Genius in Food Processing
Innovations and
patents
Among the innovative technological
features of this machine, the most
significant one is no doubt the rotor, fitted
with adjustable paddles, designed for
controlling product residence time inside
the screens and, consequently, humidity
degree of pomace being discarded.
The new rotor, covered by an international
patent, allows to vary in a quick and easy
way the angle of attack of all paddles.
This adjustment allows to vary the angle
of attack of all paddles fitted on the rotor
from 0° to 6° in respect of machine axis,
and from 0° to -6° when rotation direction
is reversed.
The process
Fruit entering the machine is sliced and
cut in middle-size pieces by the
pre-impeller, the paddles of which are
designed to allow the passage of whole
seeds, thus avoiding their breakage.
A pre-screen reduces fruit pieces to a
gross pulp where whole seeds and stems
are still to be found.
This pulp is then fed to rotor paddles
which, acting together with the main
screen, transform it into a top quality
puree, eliminating at the same time all
impurities and keeping the product
organoleptic properties unaltered.
Peels, stems and seeds are pushed,
thanks to the paddle set fixed on the
rotor, to the discharge side.

Advantages and
points of strength
The Giubileo cold extraction system,
designed to obtain top quality finished
products, has revolutionized all old
production standards and is being
adopted by the most important food
processing Companies.
Unlike what used to happen in the past,
the first operation of the processing cycle
consists in puree extraction from the
whole fruit at ambient temperature.
This technological solution, extremely
rapid, allows to minimize initial oxidation
which normally used to affect product,
prior to heating.
The advantages granted by the Giubileo
extraction at ambient temperature are
particularly important:
using a 0.8 mm screen.
• Integrity of seeds and stems, thus
avoiding taste alteration during the
subsequent heating and the presence
of unpleasant black specks in the
final puree.
• Achievement of a top quality puree
without pigmentation even when using
red peel fruit.
• Drastic reduction in puree of pesticides
usually present on fruit and vegetables
peels, preventing them to enter the
puree.
• Refining of a wider range of product
finding every time the ideal combination
in relation to the type of screen, speed
and paddle angle of attack.
• Introduction of an additional adjustment
parameter – paddle inclination –
completely independent of centrifugal
force which allows fine adjustments of
the machine according to product
• Elimination of peeling and cutting lines
when processing fruit without stones,
thus allowing significant money savings
at the time of the line purchase, as well
as a remarkable reduction in waste and
product oxidation percentage.
• Constant and high output: when
processing apples, for instance,
Giubileo can attain a 96% of finished
product with only just 4% of waste,
The diagram shows that by reducing paddle inclination from 4° to 2,5°, humidity in waste
reduces from 59% to 47%, while motor amperage increases from 72 A up to 86 A.
A less inclined paddle retains product inside the machine for a longer time thus resulting
in a higher product squeeze.

processed and of the characteristics
of the finished product desired.
Comparison with the Butterfly unit,
Rossi & Catelli’s unit which, for over twenty
years has represented the most reliable
reference point for the food processing
industry worldwide, further stresses the
advantages offered by the Giubileo unit:
A - VERSATILITY
C - WEAR AND TEAR
Formerly:
1. A different unit for each function
2. A different frame for each
motorization
Formerly:
1. NO possibility of reversed
motion – fixed paddle rotor
2. NO possibility of interchanging front
and rear screens
With Giubileo:
1. One platform only for three functions:
- Refiner for pumpable products, both
Hot-Break and Cold-Break
- Cold extractor for whole fruit without
stones (pears, apples, kiwis,
tomatoes…) or destoned fruits such
as peaches and apricots
- Press for pomace
2.One frame only for 6 different
motorizations
B - ADJUSTMENT
Formerly:
1. Rotor rotation speed (centrifugal
force)
2. Screen hole diameter
With Giubileo:
1. Rotor rotation speed (centrifugal
force)
2. Screen hole diameter
3. Angle of attack of the paddles, with
the possibility of adjusting product
residence time in the rotor.
With Giubileo:
1. YES reversed motion – adjustable
paddle rotor
2. YES interchangeable screens
D - MAINTENANCE
Formerly:
1. Handling of heavy weights
2. Necessity of transport to the
workshop for maintenance
With Giubileo:
1. NO handling of heavy weights
2. Maintenance on site
GIUBILEO - cold extractor
Maintenance
The Giubileo unit is equipped with a
motorized system for rotor removal, which
allows to carry out maintenance at the
end of the processing season directly on
site, with minimum time consumption and
an ergonomically favourable position.
In such a way, the operator can carry out
the whole maintenance operation without
handling heavy weights by hand, nor
requiring lifting devices which are often
cumbersome and dangerous.
Cleaning
Extreme functionality and easiness
characterize the sophisticated CIP
automatic washing system, which allows
total automation of cleaning cycles of
both rotor and screens while the machine
is running and the cover closed.
The drainage of washing fluids is also
automatic.
The Genius in Food Processing
Reliability, long life
Aiming at further increasing the long life
of components subject to wear and, in
particular, of screens and rotor paddles,
Giubileo gives the possibility to reverse
the rotation direction of the rotor and, at
the same time, to reverse paddle angle
of attack, to grant a wear and tear more
uniform over time.
Moreover, screen dimension has been
unified by means of a single constructive
shape which grants higher mechanical
resistance and evident advantages as far
as screen life as a whole is concerned.
For example, the infeed and discharge
screens are interchangeable, so that their
wear and tear can be uniformed and their
life lengthened; or they can also be used
on the short refining unit, where one single
screen is installed.
All the units undergo a strict testing
process in our workshop, also including
rotor balance at 1500 rpm to guarantee
the maximum stability under all working
conditions.
All units bear the
mark and are fitted
with all safety devices – such as block
micro switches – and with the proper
signs required for a safety operation.
Each unit is accompanied by the user
and maintenance manual, according
to
regulations.

Customization kits
Based on various production needs, the Giubileo unit can be
customized by means of two different kits.
SCREW
PUMPABLE FLUID
• The “Screw” feeder allows to feed
products such as pomace, or product
discarded by presses for limpid juices,
or other products which cannot be
easily pumped.
Such a kit allows to use the machine
as a press for discards or as a seed
separator.
It is composed of an AISI 304 stainless
steel hopper, an AISI 304 stainless steel
double-screw and a 0.92 kW
motoreducer.
• The “Pumpable Fluid” feeding unit
allows to feed fluid products, such as
chopped tomatoes or fruit, by means
of volumetric pumps. The feeder is fitted
with a valve for sectioning infeed
product flow.
