Before the vinification, that concludes the wine process and it is at all effects an art, an activities set must be performed probably less noble but not less indispensable.
From the harvest to the grape squeezing many of these activities can be facilitated from the machines use.
GBM that works from years in the agricultural mechanization field has studied and get ready some machines specific for the treatment of one of the main sub products of the process the grape stalk or rachis so as it is expelled from the wine pressing machines.
The grape stalks represent a reject material of the process that can be disposed in the dump or used for the composting or reused in other processes as the distillation.
In every case the grape stalks must in any way be transported in the disposing place or reused.
The grape stalk constitutes only the 5% in weight of the bunch but its structure is such as to occupy over the 80% of its volume.
When it is held in a sufficient height pile, its fibrous consistency characteristic, when the subsidence coefficient changes, it determines a density from 100 to 150 kg/m3.
On the base of these data a simple calculation allows to evaluate the problem entity:
A wine pressing process able to elaborate a bunches capacity of 50000 kg/h
• produces (50000x0.05)=2500 kg/h of grape stalks
• which increase of volume to a rate not inferior to (2500/150)=16.7 m3/h
• In 4 hours the accumulated grape stalks volume is at least (16.7x4) =66.7 m3 that can be manipulated only with a bucket if it is necessary to load it on a transportation mean.
The TR set machines are specifically designed for the grape stalks reduction through a grinding system able to bear the product density to values not inferior to 800 kg/m3.
Taking the previous example the volume produced in 4 continue functioning hours of the plant pass from 66.7m3 to only 12.5m3 with a total reduction of 81%.
The unloaded product consistency from the TR set machines is that of a fine and consistent grit which can be easily manipulated with a mechanical paddle or livened quickly from a conveyer tape.
The cutting device
All TR sets machines are supplied with an effective crumbling device constituted from two knifes set in tempered steel, one mobile and one fixed.
The knifes, of particular form, are supplied with sharpened teeth that assure a net and precise of the grape stalk constitutions.
There are 40 mobile knifes assembled with a particular sequence on a proper rotor and are kept in position from shoulder washers in tempered steel; they besides are free to oscillate on apposite centering bushings always in tempered steel.
The mobile knifes work together with con 43 fixed knifes spaced out of 25mm of size studied to optimize the cutting action and allow to generate a product extremely uniform with a size of sizes inferior to 5mm.
The rotor rotation speed is about 3500 revolutions/min, so the mobile knifes peripheral speed is very high (reaches 300km/h).
The rotor, completed of knifes is equilibrated in class 6.3.
With the aim to avoid that the irregular feeding characteristic, own of the wine pressing machines
placed upstream of the machine, determine instantaneous peaks of the requested power, the rotor is supplied with a flywheel with an inertia moment such as to assure a regular and continue functioning.
The rotor is supported from two balls double corona bearings assembled in water capacity supports.
The motion transmission from the electric motor to the rotor is realized through narrow section belts of high performances. With the aim to assure a perfect centering and alignment, the high quality steel pulleys are fixed to the respective shafts through taper-lock conical compasses.

Equipment of starting electric panel and control
The supplied electric panel minimum configuration includes the following devices:
• Start and stop buttons
• Emergency button
• Motor thermal-ammeterical protection circuit with intervention signaling warning light
• Start/triangle starting device
• Thermometer and temperature control of the rotor bearings
Equipment automatic devices
Automatic lubrication device of the rotor bearings constituted from automatic supplier cartridges of lithium soap grease.
Feeding conveyer tape control devices for the feeding break in case of overloading.
Optional automatic devices
Internal washing device driven with temporized electric valve; the automatic intervention device avoids the product accumulation on the internal walls and allows the machine continue functioning, for the washing device use it is necessary to make available close to the machine water with a pressure not inferior to 2 bar.

Why buy a
GRAPE STALK SHREDDER
These machines are made of stainless steel; they have a electric engine with attached knives or blades that allows to shredder the stalks, and reduce the volume of the grape stalk up-to 85%.
Once processed, the stalks are moved in special containers for disposal.
Many companies also use a vacuum cleaner, which sucks the grape stalks and takes them directly to the collection points.
The stalk shredder gives a lot of advantages because it transforms the stalks, which are not considered by the current laws by-products of winemaking, in material that can be disposed of or used in other ways.
In fact, many farmers once shredder the stalks use them as fertiliser. It can also be used to produce energy.
All TR set machines are in conformance with the machines directive and are provided with CE marking and the prescribed documentation.
Although the machines are provided with all accident prevention measures necessary to guarantee the operator safety, they are provided with cutting devices that are however a ranger cause for people, animals or things that are accidentally introduced inside during the functioning.
The machines and their action zone must so be considered integrating parts of the process and as all other machines, placed under the safety responsible control.
The machine so as supplied from the manufacturer can be used only and exclusively for the grape stalks mincing generated after the grape bunches wine pressing used in the wine processes.
It besides must be fed only and exclusively through an automatic system that can be or a conveyor tape or an Archimedean screw system.
All models with Archimedean screw unloading produce a sonorous pressure inferior to 85 dB.
TR4 machine in basic version functioning at the maximum power generates in its proximities a sonorous pressure that can exceed 90 dB.
It so cannot be installed in closed rooms or in placed where restrictions are prescribed to the sonorous pressure value.
If these conditions take place an adequate protection must be prepared through acoustic insulation panels.
Its conduction must in every case be performed from personnel provided with adequate protection for the hearing.
