Abstract: A portable, automatic juice-extraction machine comprising a cabinet on which is mounted a hopper for loading with the juice source material, such as apples, pears and the like, a conveyor belt to transport the material from the bottom opening of the hopper into a loading chute for dropping into a grinder, where the material is ground into pieces and then dropped by gravity into a centrifuge where the pieces are further ground into a pulp for action by centrifugal forces to separate the juice from the pulp and transmit the juice into a holding tank for dispensing and the waste material into a garbage bag where the improvements include offsetting the loading chute into a slanted transition chute, to prevent blowback of the ground material, and a pair of spaced-apart projections directed outward from the top of the centrifuge bowl into a slanted area formed in the centrifuge lid to upset the cake buildup of the waste material thus allowing the material flung from the top of the centrifuge bowl to carry the cake

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.
