| DESTEMMER - CRUSHERS - mod. DPO |
1. DESTEMMING UNIT
The unit is composed of an holed rotating cage and a counter-rotating beating shaft, each one independently driven by means of mechanical variable-speed drives The holed cage turns continuously, thus keeping always clean.
The cage holes are of decreasing diameter and their drawn edges are burr free for a better grape handling
The beating shaft is equipped with rubber shoes to avoid grape tearing.
The grape feeding is dosed by a screw positioned at the beginning of the beating shaft.
The slow variable speed guarantees a perfect soft destemming with whatever kind of grape. |

Inspection doors
In order to increase inspection/cleaning operation safety, access doors are equipped with special switches, locking system in opened position and closure oil dumper.
Destemming/no destemming system
With an easy movement, an inside device allows to cut out the destemming function.
Moreover a proper door positioned at the beginning of the holed cage allows a partial destemming. |
 |
Cage washing device
A drilled piping has been provided for a quick and
effective inside washing.
Eccentric mechanism
The machine is equipped with a device to adjust the axial position between cage and shaft, thus obtaining different clearances between rubber shoes and cage; this possibility is particularly helpful when processing mechanically harvested grapes, in order to assure the effective removal of leaves and shoots from the inner cage surface.

2. CRUSHING UNIT
MULTIPLE RUBBER CONES system.
Rubber cones set with special manufacturing shape assembled on two shafts counter-rotating at different speeds.
MULTIPLE RUBBER CONES ADVANTAGES:
- crushing capacity equal/higher than that of cylinders of more than double outer diameter (progressive crushing without the possibility of product accumulation inside the feed hopper).
- saw tooth shaped product passage (high efficiency with small cone size and low rotation speed).
- adjustable clearance between cones (from 2 to 32 mm) to carry out the requested crushing avoiding skin and stalk tearing.
Crushing/no crushing system
Wheel mounted crushing unit slide allowing both the crushing function cut out and a comfortable cleaning operation; a reference switch enables the crusher operation only when in position.

| PICKER-PRESSER-DESTEMMER – mod. SPD |
Thank to the total independence between destemmer and crushing unit, this machine has the possibility to work also as pickerpresser-destemmer.
Placing the crushing unit with the MULTIPLE RUBBER CONES over the feeding hopper, the “SPD” version is obtained.
Such shape is recommended in particular when processing traditionally harvested grapes; this work concept is very suitable also with mechanically harvested grapes.

1. PICKER-PRESSER
Grape picking+pressing operation is carried out by means of the MULTIPLE RUBBER CONES system; in fact the two shafts, counter-rotating at different speeds, originate a relative speed between the opposite cone lines, thus causing the berries to detach from the stalk under the smallest possible pressure.
This type of operation results in a kind of soft berries removal, since almost all the grape split at the attachment to the stalk, helped by the spiral movement of the bunch.
Moreover the possibility to differently space the rubber cones makes possible to carry out a typical kind of crushing, squeezing the grape without mashing the skin.

2. DESTEMMER
Once the berries have been separated from the grape stalks thank to the above operation, this unit, equipped with shaped rubber shoes, has the function to eject the stalks, intact and dried, as well as extraneous matters, out of the cage.
When processing grapes coming from mechanical harvest, the picker-presser placed before the destemmer allows the release of some liquid helping the removal of leaves from the cage inner surface.
