    • 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 material impinging thereon to migrate downwardly under centrifugal force, thereby providing a self-cleaning type action impeding the detrimental accumulation of excess pulp material over the fiter surface. Means are provided for selectively releasing the accumulated pulp material from within the rotating fiter without significantly interrupting the operation of the apparatus, and for collecting the released pulp in removable pans at the bottom of the apparatus enclosure.
    • 离心机用于通过离心力粉碎和过滤从植物材料如水果或蔬菜中提取果汁成分。 与固定料斗的开口顶部相接触的植物材料在与快速旋转的板构件的表面延伸穿过料斗的开口底部的一系列快速移动的非叶片钝的突起接触时被粉碎。 然后将所得的果汁和纸浆混合物在离心力下通过形成在固定料斗的底部和旋转板的上表面之间的预定高度的环形空间向外抛出。 附接到旋转板构件并围绕旋转板构件的截头圆锥形过滤构件妨碍了粉碎植物材料的纸浆组分向外运动,允许汁液组分通过。 将如此分离的果汁组分收集在围绕旋转过滤器和板的固定外壳内,并根据需要传导至设备外部进行分配。 过滤器的壁朝向其底部向外倾斜,以促使撞击在其上的植物材料的插塞部件在离心力下向下移动,由此提供自清洁型作用,阻止过量纸浆材料在叶轮表面上的有害积聚。 提供了用于在不显着中断装置的操作的情况下选择性地释放积聚的纸浆材料的装置,并且用于将释放的纸浆收集在装置外壳的底部的可移动盘中。
