Berry/Cherry grading machine sorts cherries according to needed calibration values. In its essence, the calibrator is a drum type of device. Can be manufactured with one or two drums. Fruit is fed to the grading machine by means of a blade elevator mounted on a wash tank for preliminary fruit washing and for separation of light impurities (leaves, stalks, etc.). Main fraction of fruit is discharged by means of a longitudinal belt conveyor positioned underneath the grading machine. Remaining fractions are lead out through laterally mounted chutes.
