GRAPE SELECTION LINES

COMPLETE GRAPE SELECTION LINE

Grape selection line is composed by MADRINA 50 or 100 stalk-removing pressing machine, vibrating selection table, motorized adjustable rubber rollers unit to properly press each grape variety and by product transfer PR 250 pump.
Selection belt and belt elevator can be added to grape feeding.
Grape selection line allows to process the best grape rejecting the non suitable ones to get top quality product.

VIBRATING AND BATCHING TABLE

The vibrating, batching table TDV.1200 is positioned before the sorting table or the stalk remover machine and allows to measure out the grapes regularly. The vibrations of the plate allows the grapes to move further and the holes in the table itself allow must recovery. It is equipped with electronic speed variator to adjust grapes movement.

BELT SORTING TABLE

The belt sorting table TSN is used to remove manually unripe or wasted grapes or bunches of grapes, leaves or any other kind of material. It is equipped with speed variator and adjustable feet in height. The belt is made of PVC, duly provided with food certification. The separation channels make the sorting procedure easier; the selected grapes run through the centre of the belt, meanwhile the dismissed parts are conveyed outside.

ELEVATOR BELT

The elevator belt EN is used to transport the grapes, stalks and rape. It is equipped with 4 wheels, where 2 are turning, and is available with different lengths. Moreover, it carries a hydraulic piston with manual pump to adjust height. The belt is made in food certified PVC and is equipped with series mechanical speed variator.

MADRINA 100

MADRINA 100 stalk remover-pressing machine is projected for a soft processing of the grapes; receiving hopper can be supplied with feeding screw or with direct skid to the holed basket. It is equipped with telescopic legs to be fitted into selection lines and with electronic inverter to change RPM. It has double holed stainless steel rotating basket, adjustable rubber paddles beater, motorized pressing rollers unit hinged to the hopper. Motor drive unit is assembled on the stalks outlet side and it is openable through hydraulic pistons. The basket, the beater and the roller unit are removable for easy cleaning.

VIBRATING SORTING TABLE

The vibrating sorting table TSV is suitable to sort manually or mechanically harvested grapes in order to remove all the unneeded parts. The motorvibrators allow the grapes to go further on the surface thanks to the vibrations of the working plate. At its beginning part, the table is equipped with a draining grid for the liquids with stocking tank, provided with plug (on demand). On one side it carries removable guards that make possible to separate the selected product from the dismissed one. Moreover, it has an electronic variator to adjust the moving speed of the product, 4 rotating wheels and 4 adjustable feet to reach therequested height.

MOTORIZED ROLLERS GROUP

The motorised rollers for grapes pressing receive the selected and stalk-removed grapes through a loading hopper with custom-made dimensions. The machine body is made up of the group of rubber pressing rollers with adjustable distance allowing a proper pressure of different berry sizes and of a variable speed geared motor for pressing speed adjustment. Besides it is designed in such a way that must can be unloaded onto a pump with a hopper and the frame height can be custom-made.

PERISTALTIC PUMP

The peristaltic pump is suitable for the processing of wine, whole, pressed and stalked grapes and rapes. Its functioning is based on the rotating rolls pression principle, where, the product is pushed away to the exit by pressing progressively a rubber tube. The alternation between compression and relaxation of the tube allows the continuous flow of the product into the system and consequently the product feeding never stops. This principle allows to work by avoiding any kind of oxydation, shaking, product emulsioning, grape crushing and the contact between pumping system and the product itself. The CVS (Continuous Vacuum system) consists of using an electric vacuum pump and a vacuum gauge whose goal is to make easier the total opening of the tube in the semi-hermetic sealed box. That allows to get higher performance in decantation with minor product crushing.

PR250

The PR 250 pumps are made of AISI 304 stainless steel and are suitable for transferring grapes and marcs. The product is sent into the hopper auger inside the pump casing where it is pushed to the outside by the elliptic rotor via 100 mm pipes for grapes and marcs (60 or 80 for grapes with stalks removed). The pumps can be fitted with a compensation chamber and with a speed variator. They are ideal for combination with the Precisa stalk remover-pressing machines manufactured by us.
