Definitions

  • the present invention relates generally to a shredder, and more particularly to a shredding member. Still more particularly the invention relates to a shredding member for use in juice extractors. e
  • Juice extractors can be divided into two basic categories, namely the one in which the material from which juice is to be extracted is subjected to pressure so as to extract the juice therefrom, and another category in which the materal (fruit, vegetables or the like) is shredded for the purpose of disintegrating its cellular Structure and to obtain the juice in this manner, the present invention is particularly concerned with this latter type of extractor.
  • the shredding member Will usually be located in a rotatable drum, with the fruit being fed into the proximity of the teeth of the shredding member via a feed hopper which extends into the drum and whose lower edge is located closely above the teeth of the shredding member, which latter rotates underneath this lower edge.
  • a feed hopper which extends into the drum and whose lower edge is located closely above the teeth of the shredding member, which latter rotates underneath this lower edge.
  • the present invention overcomes the aforementioned disadvantages.
  • the present invention provides a shredding member which is inexpensive to manufacture, simple to produce, and highly eiective in disintegrating the cellular structure of fruit or other materials from which juice is to be extracted.
  • the shredding member according "to the present invention is also very easy to clean, thus fulfilling another of the important requirements which are made of such articles.
  • a plate-like shredding member which consists of relatively thin elastically deformable material.
  • This member has a convex first side which is provided with a plurality of clusters of projecting teeth, and a concave second side.
  • the latter is adapted to overlie a substantially planar support surface in surface-to-surface engagement therewith in response to deflecting pressure which is exerted upon the convex first side, so that the shredding member is deflected into planar position overlying; the support surface and is reinforced by the same.
  • FIGS. 1 and 2 a supporting plate 1 of a juice-extracting centrifuge has mounted thereon a removable extracting basket or drum 2.
  • the drum 2 is mounted on a rotatable shaft 3 which in turn is connected with a nonillustrated electric motor of conventional type.
  • the drum 2 rotates with the shaft 3 in response to rotation of the latter, with which it is concentric.
  • the shaft 3 is, as evident from. the drawing, provided with external screw threads for a purpose still to be discussed.
  • This shredding member is identified with reference numeral 5 and is in the shape of a disc having a central opening through which the shaft 3 passes. It'consists of relatively thin elastically deformable sheet material, such as sheet steel or the like, which is not in itself capable of resisting deformation under the influence of torsionaltstresses which develop when the member is rotated in engagement with the fruit or other produce from which juice is to be extracted.
  • the disc 5 is of substantally concavo-convex configuration, as clearly seen in FIG. l, and is provided on its convex side, that is the side which faces away from the support surface constituted by ythe bottom wall 4 of the drum 2, with a plurality of clusters of teeth 6.
  • each of the clusters comprises no less than hree such teeth 6.
  • a suitable nut member 7 (compare FIGS. 1 and 3) is provided with an internal screw thread which meshes with the extemal screw thread of the shaft 3.
  • the shredding member of 5 is now reinforced and protected against torsional twisting so that the lower edge portion of a feed hopper 8 for fruit or other produce from which juice is to be extracted, can be placed into close proximity with the teeth 6 of the member 5.
  • the gap 9 which exists between the teeth and the lower edge portion of the hopper 8 will always remain unchanged, because the member 5 cannot become deformed, and the gap 9 is so small that only finely shredded produce can pass therethrough from the interior of the hopper 8.
  • a plate-like shredding member of relatively thin elastically deformable material said shredding member having a convex first side provided with a plurality of clusters of projecting teeth, and a concave second side adapted to overlie a substantally planar support surface in surface-to-surface engagement in response to deflecting pressure exerted upon said convex first side, whereby said member is reinforced by said support surface through such surfaceto-surface contact therewith.
  • a rotary support having a substantally planar support surface; a substantally plate-shaped shredding member of elastically deformable sheet material having a concave first side overlying said support surface, and a convex second side facing away from said support surface and being provided with a plurality of clusters of projecting teeth; and means operatively associated with said shredding member and releasably defiecting the same into surface-to-surface engagement of said first side with said support surface.
  • each of said clusters comprises a plurality of teeth.
  • each of said clusters comprises at least three teeth.
  • each of said clusters comprises a plurality of teeth, the teeth of each cluster being of identical length.
  • said teeth are constituted by portions of said shredding member which projects transversely from said second side in the direction away from said first side.
  • said shredding member comprises a plurality of apertures each associated with one of said clusters, and wherein the teeth of each cluster form an annulus about the respective aperture.
  • said shredding member is a disc, and wherein said apertures are arranged in form of a spiral on said disc.
