The machine consists of a loading hopper, which contains the grapes to be
destemmed. At the bottom of the loading hopper, there is a auger feed that pushes
the grapes towards two rollers that will crush them.
It then conducts them into the lower part where, thanks to a circular movement, the
destemmer shaft paddles separate the grapes from the stems. The grapes, together
with the freshly squeezed must, fall into the lower bin through the grate situated
inside the machine. They are then taken by another auger feed into the centrifugal
must pump that transfers them into a fermenting vessel.
The destemmer shaft is manufactured in such a way that through its helical
movement, the welded paddles on it push the stems to the output shoot.

4. INSTALLATION
4.1 Preparation for installation
Before installing the machine, it is necessary to control the suitability of the place
where it will be located. It being understood that such evaluation must consider the
specific conditions of the location, some important general controls are the following:
Check the overall dimensions of the machine, leaving a distance of at least 70
cm from any type of fixed obstacle (walls, columns, walkways) to allow the
operator to move without impediments. Check that the foreseen location of the
machine does not interfere with any other machinery.
Check the suitability of flooring in terms of stability, cleanliness and slope.
Insure constant, uniform lightning to avoid risks due to shaded areas.
If the machine is positioned near to transit zones, you must place suitable
barriers around it for protection of accidental bumps with trolleys, trucks etc.
If it is located on intermediate floors, elevated floors or raised platforms, check
that the maximum carrying capacity is more than the overall weight of the
machine and any other accessories such as lifting equipment etc. always
considering an adequate safety factor.
4.2 Transport, unloading and installation
The machine is supplied already assembled into its operating configuration so the
risks due to movement concern the whole machine.
Transport must be by qualified transporters able to guarantee the correct movement
of the transported materials.
