WINERY & VINEYARD EQUIPMENT 106 WINES&VINES January 2016 ARMBRUSTER ROTOVIB The Armbruster Rotovib employs a patented vibratory movement to "pluck" grapes from the stems, allowing thorough berry removal at slower speeds. Destemmed berries fall onto the next stage of sorting, while un- ripe grapes and raisins stay af- fixed to the rachis and move into the waste stream. A new "Roller- sorter" add-on feature provides additional mechanical sorting with interlaced silicon rubber spools that carry berries toward the collection point while allow- ing MOG to fall through as waste. The machine is available in three models with throughput rates of 10-30 tons per hour. Distributed through Scott Labo- ratories. Price for Rotovib 10 with Rollersorter: $32,500. scottlab.com BUCHER VASLIN The Delta Oscillys machine by Bucher Vaslin uses inertia to separate grapes from the stems. Grapes enter the machine through a small hopper and fall into cylindrical cages that swing back and forth. The movement forces berries to separate from the stems, and they then fall onto a rolling sorter table. The manufacturer claims the Oscillys produces a grape stream of just 0.2% to 0.5% MOG. Throughput is 2 to 16 tons per hour and can be adjusted by the size of the cage holes and swinging speed. Price for Oscillys 100: $42,000; Oscillys 200 with two destem- ming cages: $56,000. buchervaslinusa.com PRODUCT FOCUS Destemmers The next generation of destemmers features new methods for removing MOG as well as variable settings for speed and motion that enable winemakers to further customize how they process grapes on the crush pad. Many of these machines feature optional crushers and additional sorting capabilities. By Andrew Adams Armbruster Rotovib Bucher Vaslin Oscillys 200
