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. Its 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.
