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 into the waste receptacle and render the machine self-purging.
