A fruit destemmer leaving an endless conveyor belt made up of a plurality of counter-rotating metal rollers rotatably supported at each end by endless chains. The fruit destemmer has an inclined bed with a driven shaft at each end. Each driven shaft has a wheel at one end and a sprocket at the other with the positioning of the wheel and sprocket being reversed on the other drive shaft. The continuous chains are driven by spaced sprockets mounted on a shaft positioned below the inclined bed. A rotatably mounted shaft, having a wheel mounted on each end, presses each continuous chain into close contact with the driving sprockets. Any foreign matter which enters between an endless chain and a sprocket causes the endless chain to slip on the associated wheel thereby maintaining chain alignment. The rollers used to form the endless fruit conveying belt are made of hard anodized aluminum which has a surface pattern to reduce fruit skinning. The rollers are caused to rotate counter to each other by a pair of spaced segmented gear racks, each segment of which is individually adjustable. The number of segments in contact with the rollers can be decreased to reduce fruit damage as the fruit becomes softer as the fruit growing season progresses.
