ABSTRACT:
An electronic fruit grading machine includes an endless chain having positioning rollers or bars which rotate and on which the fruit coming from a hopper is positioned in rows. The grading machine includes an electronic apparatus capable of detecting surface marks or defects in the fruit which is situated on the bars. The fruit is arranged in transverse rows and is displaced at a certain speed under a standard television camera. The feed of the fruit from the hopper to the endless chain is carried out by a cylindrical drum acting as a feeding device. On the surface of the cylindrical drum are rows of holes, and adjacent each hole is provided a wedge, one face of which follows the prolongation of a radius of the cylindrical drum and is arranged for the expulsion of extra fruit adhered to the periphery of the cylindrical drum.
