• Gold medal winning Opti-Grape™ technology: up to five times better cleaning performance
• Honourable mention for in-cab anthocyanin readings: monitor grape maturity in real time
New Holland has received a gold medal and an honourable mention at the 2013 Sitevi awards. A gold medal was bestowed on Opti-Grape™ technology, which delivers best-in-class cleaning performance. The CAN bus system, which displays the data from FORCE-A’s real-time grape maturity sensor on the IntelliView™ III monitor on Braud 9000 machines, was recognised with an honourable mention.
“We are delighted that these advances in grape harvesting technology have been recognised.” Stated Gaffoglio Maggiorino, Head of the Grape Harvester business. “We are fully committed to ensuring that our complete range of Braud grape harvesters delivers unsurpassed quality for today’s exacting viticulture businesses and customers.” Opti-Grape™ technology: up to five times better cleaning performance
The gold medal winning Opti-Grape™ technology uses a unique in the industry system, which delivers an air cushioned blowing surface: a rotary turbine blows air through a fine mesh to eliminate all material other than grape (MOG) before it falls down into the hopper. Situated at the end of the cleaning system and above the hopper, the driver adapts the air cushion’s strength by changing the turbine speed depending on the desired quality of sorting. As a result, the driver can directly adjust the quality of grape cleanliness. The air flow is directed through 4300 2mm diameter holes to remove even the tiniest impurities such as petioles, stalks, wood, bits of leaves and stems, together with dried, mouldy and botrytised grapes. This material is blown above the grapes and removed. The result is a higher quality, less ‘green’ tasting wine, which enhances grower profitability and the desirability of the harvest.
The high pressure air cushion surface technology has been developed in addition to an host of improvements in the cleaning system, which include a new pre sorter ; two sets of rollers in the pre-selection area, which enhances cleaning efficiency by up to 20%, as MOG simply falls away through the gaps. Furthermore, the top aspirator on the receiving conveyor has also been upgraded to remove even more debris during the initial cleaning process. Grape quality has improved significantly, as only the grapes which remains on the bunch pass through the final destemmer, protecting those which have already been separated.
The Opti-Grape™ system underwent rigorous field testing, both in the Northern and Southern hemispheres and when compared to traditional cleaning technologies, the Opti-Grape™ system dramatically reduces MOG levels by up to five times, with MOG content as low as 0.1%. This can assist grape growers in maximising profitability, as the need for additional MOG sorting is substantially reduced. The system has no productivity impact, and can be used at normal harvesting speeds for most varieties of red grape. Operators which harvest both red and white grapes can simply disengage the system from the cab. By removing MOG, but also dry, mouldy and botrytised fruits, the system influences the grapes at the beginning of the vinification process, which directly impacts the quality of the final product. In-cab anthocyanin readings: monitor grape maturity in real time
New Holland has developed full compatibility between the Braud 9000’s CAN bus network and FORCE-A’s Multiplex® sensor to display real-time anthocyanin readings on the IntelliView™ III colour touchscreen monitor. Available across the entire Braud 9000 range, this Multiplex® sensor is situated above the hopper and uses unique optical technology to determine the anthocyanin content of the grapes, a key indicator of grape maturity. This solution is instantaneous and non-invasive, so maintains grape integrity. Operators can view and record the milligrams per litre of anthocyanin as well as monitor the heterogeneity of the hopper on the IntelliView™ III screen thanks to CAN bus technology. The anthocyanin reading is displayed for each load, which helps in the decision making process for subsequent vinification. This system can also be linked to the Braud 9000’s integrated mapping functionality. In conjunction with GPS data for positioning, a map of the anthocyanin spatial variability of the entire parcel can be produced to enable vineyards to tailor inputs to ensure optimal grape maturity, as well as selecting individual parcels for particular blends of grape. This data can be fully integrated with that obtained from EnoControl to further refine the grape harvesting process.
