Optical sorting line x-tri

The DEFRANCESCHI group is pleased to present the x-tri optical sorting line. The development is the result of the collaboration with the company PROTEC, active since 1991 in the field of selection, equipped with optical sensor.

The x-tri line is composed of destemmer, vibrating feeding table and optical unit. Elevator belts might be needed to compensate different heights. The optical unit is manufactured by PROTEC, but the distribution in the wine world is an exclusive of DEFRANCESCHI group (excluding the United States of America).

Operation x-tri: the berries on the outlet from the destemmer are spread on the vibrating feeding table and from there on the belt of the optical unit. The optical sensor recognizes the defects (vegetal elements, insects and foreign bodies) and actuates the ejecting system (air nozzles). The clean product is transferred into the crusher for further processing. The optical system can also recognized unmature berries (different color) and eject them with the other defects.

The defects to be eliminated can be set trough the use interface. The x-tri line can work up to approx. 15 t/h. This capacity depends on the grape variety, maturity and quantity of defects.

The setup was extensively tested during last harvest in Italy and France. Excellent results were achieved with different varietals at Château Reillanne (Le Cannet des Maures, France), Château Mont-Redon (Châteauneuf-du-pape cédex 1, France) and Ruffino - Tenuta La Solatia (Monteriggioni, Italy).

During next SITEVI at Montpellier, France (1-3 december 2009) the x-tri will be presented on the DEFRANCESCHI AMOS stand (Hall 234, n° 234 F 078)
