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.
