Abstract: A semiautomatic pineapple peeler in which adjustable width knife blades sever the ends of the pineapple and concentric cylindrical knives core and peel it, leaving the detached core in the peeled pineapple. The one step process is driven by two D.C. electric linear ball screw actuators, sequenced by an integrated circuit logic board and magnetic proximity limit switch arrangement. The peel is split in half by two radially mounted fins on the top and bottom of the large cylindrical knife, allowing the waste to be collected below.The pineapple machine completely removes all of the peel and cores a single pineapple automatically, eliminating the two step manual operation of first cutting the ends off and then using the existing labor intensive lever operated coring and peeling devices.
