2. GENERAL INFORMATION ON THE MACHINE
2.1Description of the machine and operation
More and more people in recent years have approached the natural products and the
packaging of homemade jams or fruit processing for subsequent distillation; for them
Grifo has created a very functional semi-professional pitting machine that allows the
user to quickly drip different types of fruit, such as cherries, apricots and plums using
the special grids provided.
The models referred to in this manual differ only for the material used, enamelled steel
or stainless steel; the catalog names of the models are as follows:
DESTONER BY ELECTRIC MOTOR WITH 2 S/STEEL BASKET (DENS)
The machine allows to separate the pulp from the stones, completely crushing the
fruit, creating a mush that can be used for jams, fruit jams, distillations or
fermentations. Composed of a funneled hopper and a case all in enameled steel and
thanks to an electric motor mounted on the machine, which allows all the
mechanisms present to be activated, the products pass through the rollers for a first
crushing and then arrive in the separation basket , where a beater with rubber
spatulas squeezes the fruit against the stainless steel grid dividing the pulp and the
juice from the pits. The removable grill is made of stainless steel while gears and
rollers are completely made of nylon. The rollers are also adjustable by a few
millimeters thanks to special supports. Robustness and long life are guaranteed by
the high quality materials used in the construction.

S/STEEL DESTONER BY ELECTRIC MOTOR WITH 2 S/STEEL BASKET
(DENI)
It is the version built completely in stainless steel. Grifo has created a very functional
and practical pitting machine that allows the user to quickly drip different types of fruit.
The possibility to install screens of various holes allows the use of the machine with
many types of product, and in particular: cherries, prunes, apricots (to extract the pulp).
The machine performs a complete separation of the pulp from the inner core, and
simultaneously crushes the fruit, creating a final product suitable for fermentations, fruit
juices (carrying out multiple steps), and jams. Composed of a funneled hopper and a
case entirely in stainless steel like all the screws.
Thanks to an electric motor mounted on the machine, which allows all the mechanisms
present to be activated, the products pass through the rollers for a first crushing and
then arrive in the separation basket, where a flap mixer centrifuges the product and
leaves it underneath the machine the pulp andthe juices andfrom the front the kernels.
The removable grill is made of stainless steel while gears and rollers are completely
made of nylon. The rollers are also adjustable by a few millimeters thanks to special
supports. Robustness and long life are guaranteed by the high quality materials used
in the construction.

responsibility of the user. Some useful indications in this regard are as follows.
Placement
The machine must be positioned so as not to constitute an
obstacle to the movement of people and equipment, and in
such a way as to ensure that all the points which may require
the presence of an operator are easily accessible.
Environment
The environmental conditions (temperature, humidity,
magnetic fields, etc.) must be such as to guarantee the
correct operation of the electrical components
Noise
The noise level of the machine is less than 70 dBA.
Any tampering of parts of the machine, and in particular of parts
connected with the safety of the same, relieves the manufacturer

4. INSTALLATION
4.1 Preparation for installation
Before installing the machine, it is necessary to evaluate the adequacy of the place
where it is to be positioned. Notwithstanding the fact that this assessment must
consider the specific conditions of the place in question, some important general
measures are as follows.
Check the overall dimensions of the machine, leaving a distance of at least 70
cm from any type of fixed obstacle (walls, columns, pedestrian crossings) to
allow the operator to move without obstacles.
Check that the intended positioning of the machine does not cause interference
with other machines.
Check the adequacy of the flooring in terms of stability, cleanliness and slope.
Ensure constant and homogeneous lighting to avoid risks due to shaded areas.
In the case of positioning the machine near transit areas, set up barriers around
it to protect it from accidental impacts.
If the positioning must be carried out on mezzanines, upper floors or raised
areas, check that the maximum capacity is greater than the total weight of the
parts to be supported and any accessory weights such as lifting means, etc.,
always considering an adequate safety factor .
4.2 Transportation, unloading and installation
The machine is supplied already assembled in the operating configuration so that the
risks due to the movement concern the whole assembly.
Transport must be carried out by qualified transporters able to guarantee the correct
handling of the transported material.
GRIFO Macchine Enologiche S.n.c. assumes no responsibility for
damage resulting from transport. The goods are intended to be
supplied ex works.

Upon receipt, check the integrity of the different parts of the machine and that there
are no missing accessories necessary for installation.
Verify that the supply matches the order specifications.
Complaints concerning the goods supplied must be sent, in writing, to the company
GRIFO Macchine Enologiche S.n.c. within 15 days of receipt of the game.
Pay the utmost attention when handling the machine, respecting
the provisions of current regulations and any safety procedures.
The machine must be moved by two adults, gripping the four support tubes at the
end.
4.3 Placement
In positioning the machine, in addition to respecting the general indications of
paragraphs 3.2 and 4.1, particular attention must be paid to the dimensional
compatibility between the support tubes and the container above which the machine is
placed. The container must be placed so that the stalks, coming out of the machine,
fall out of them.
The containers used must have a shape and size such as to guarantee the stability of
the machine. The distance between the points of support must be not less than 850
mm (Fig. 3).When positioning the machine, the height must be chosen so as to
guarantee the inaccessibility of the auger and of the rollers placed on the bottom of the
hopper. In this regard, the use of a protection box to be fixed by screws to the hopper
is provided.
Considering that the box has a height of 450 mm, the upper end of the box must be at
a height of not less than 1600 mm.
