Abstract: In a produce peeler a plurality of rolls (14) are mounted in a "U" configuration around an auger (26) and are individually rotated by hydraulic drive motors (16) to peel produce passing through. The rolls are positioned in a hyperbolic configuration to enhance the produce tumbling and thereby improve the peeling action. The rolls are also interchangeable with separate speed controls for each.

Abstract: A color detecting device comprising a head (14) supported on an arm (30) for oscillatory motion over the product (11) being color measured to render a signal responsive to the average color of the product. A height detector (44) provides a signal indicating the distance between the product and head and is used to modify the color signal accordingly. A temperature sensor (39) in the head indicates an overtemperature condition for causing movement of the head away from the product. The screen (17) transparency is measured by the indicator (47, 48) to indicate when the screen is dirty.
