Definitions

  • This invention is for improvements in orrelating to crushing machines, expressing machines (i. e., machines for extracting .Y liquids from solid or semi-solid matter) and the llike (hereinafter generally referred to collectively as crushing machines).
  • the invention is particularly concerned with a machine for expressing oil from nuts and seeds.
  • the well known worm-expeller type of expressing machine is open to the objection that friction on the worm and cage by the material being operated upon rapidly results in wear of said parts and entails frequent replacement thereof. This frictional wear cannot be avoided'because a certain amount of friction between the worm and the material is Anecessary for the operation of the machine. f
  • An object of the present invention is to provide a crushing machine in which there -is little or no relative movement, between the crushing members and the material being treated, tending to cause serious and rapid wear of said members.
  • a further object of the presentinvention is to provide a crushing machine inwhich a positive crushing pressure is exerted on thematerial to be treated which pressure is not -dependent to any great extent, if at all, on the frictional properties of the material.
  • a still further object of the invention is to provide an improved crushing machine of simple andirobust construction.
  • a still further object of-'the invention is to provide a machine in which the crushing pressure is applied to the material without an objectionable increase in the temperature thereof.
  • a crushing machine comprising two c members which constitute opposite walls of a wedge-shaped or tapered space or chamber, a step-by-step mechanism for feeding material step-by-ste'p through said space, and means for moving at least one of saidmembers towards ⁇ ment to one of said members relatively tothe other to feed material step-by-step through said space or chamber, and pressure applying means for moving at least one of said members towards andaway from the other, duringhaltsfinsaid nitermlttent movement of one member. SQ as to crush the material in the wedge-shaped space or chamber.
  • a crushing machine comprising a wheel and a crushing member, the rrim of the wheel and the crushing memberl constituting opposite walls of a wedge-shaped or tapered .crushing space or chamber, a step-by-step mechanism for imparting intermittent movement tothe wheel relativefly to the Ycrushing memberto feed material stepby-step through said space or chamber, and pressureapplying means-'for moving the crushing member towardsand away from the rim of the wheel during halts in the intermittent movement thereof so a s to crush the materialin the wedge-shaped space or chamber.
  • the crushing member is pivoted to the machine frame, for movement towards and away from the rim of the wheel, and said pivot is arranged, ywith respect tothe Wheel, so that the space between the rim and the ⁇ crushing member is of the l required wedge form, said space decreasing inV adirection vfr pm the feeding to the pivoted ⁇ end of the crushing member.
  • the material is f ed. into the space between the rim of the wheel and the crushing member, by a feeding member and during the crushing operation confined in said space by the feeding member.
  • the wheel takes several step-by-step movements in ⁇ traversing the complete span of the v crushing member so that each charge of material Vis ⁇ subjected tof several crushing operations,
  • the crushing operation will be of increasing severity so thatthorougn extraction of the liquid will b e obtained without an excessive and objectionable squirting-out" in the initial stages.
  • vthe crushing member may be Ymade of hollow or cavity construction so that a heating or vcoolingffluid can be introduced into it in cases*A where temperature control of the material being treated is advantageous.
  • he permeable rim of the wheel or the permeable part ⁇ o fethercrushing member may com-- prise a series ofv bars clamped together withA .shims or narrow spacing piec es' between them so that a plurality of intersiis are f c'rmed..
  • a method of crushing materials (e. g. to express liquids from solid or semi-solid material) which comprises the steps of feeding material mechanically, by a Yconveyorhaving a permeable support for the material, through a wedge-shaped ortaperingcontractible crusing chamber, halting said material intermittently in said crushing space and applying pressure to express the liquid by contracting the. crushing space during such halts, whereby: the, material is subjected to a series of crushing operations of increasing severity.
