The ROTOVIB is the latest development in quality wine grape processing equipment. Its goal is to provide the gentlest handling of fruit, yielding the maximum number of whole berries and a minimum of stems. It’s patented vibration technology is used to “pluck” the grapes from the stems without the need to thrash the clusters within the destemming cylinder. Pin shaft speeds can therefore be reduced by 60% or more. Under-ripe or raisined fruit remain on the stems, increasing product quality.
Though first trialed in Europe, the North Americans are the first to truly embrace the ROTOVIB concept. Many units were delivered in the United States during both 2007 and 2008. Most often these destemmers are coupled with Vaucher-Beguet grape sorting equipment to optimize fruit quality. Standard features include a variable frequency pinshaft drive and reversing destemming cylinder. Some of the options available for the ROTOVIB include crushing rollers, swivel casters and custom frames to fit a variety of production layouts.
