Abstract
A centrifuge-type apparatus for extracting, by pulverization and filtering under centrifugal force, the juice component from plant materials such as fruits or vegetables. Plant material introduced into the open top of a stationary hopper is pulverized upon contact with a series of fast-moving non-bladed, blunt protrusions extending upwardly from the surface of a rapidly rotating plate member extending across the open bottom of the hopper. The resultant juice and pulp mixture is then thrown outwardly under centrifugal force through an annular space of predetermined height formed between the bottom of the stationary hopper and the upper surface of the rotating plate. A frusto-conical filter member attached to and surrounding the rotating plate member impedes the outward motion of the pulp component of the pulverized plant material whle permitting the passage of the juice component. The juice component thus separated is collected within a stationary enclosure surrounding the rotating filter and plate, and conducted to the exterior of the apparatus for dispensation as desired. The wall of the filter is slanted outwardly toward its base to encourage the plug component of the plant mater…
