Definitions

  • the present invention corresponds to the technical field of diffusion bands used in diffusers to extract the sugars of different raw materials through the continuous washing of the raw material chopped and deposited on the diffusion band and in particular to the afofador of the situated raw material on said diffusion band to sponge the bed of raw material located therein.
  • the afofadores are necessary because, during the course of advance of the bed of raw material on the set of palettes of the band of diffusion, said bed is receiving the repeated impacts of the jumps of juice that provide the flips of the balances. These repeated impacts of juice, make the bed of raw material is compacted and consequently, that it becomes impermeable and makes it difficult to pass the juice through the bed and the set of pallets. This same effect of compaction of the raw material occurs in diffusers that use a continuous washing of the raw material.
  • afofadores are arranged along a diffusion band, as many as the type of raw material that is being processed requires, since there are more prone materials to be compacted that require more quantity of afofadores than materials with less capacity to compaction
  • These chokes are located just a few centimeters above the vanes or set of blades that make up the diffusion band by placing the shaft of the choker in a transverse position to the movement of the blades and parallel to them, so that they can focus part of the raw material bed, without interfering with said pallets.
  • the spreader for the diffusion band used in diffusers to extract the sugars of different raw materials through the continuous washing of the raw material chopped and deposited on the diffusion band, where the stiffener is located on the diffusion band to sponge the bed of raw material located therein, it comprises a central axis arranged horizontally, transverse to the direction of advance of the raw material and such that it covers the total width of the diffusion band, and from which at least one longitudinal fin
  • At least one end of the central axis is connected by means of connection to a geared motor that generates the rotational movement of the at least one fin on the surface of the raw material bed.
  • said at least one fin has a width such that the end thereof, in its lowest rotation position, is comprised between the plane defined by the diffusion band and the upper plane defined by the raw material to be treated.
  • the spreader comprises means for fastening the ends of the central axis to the side walls of the diffuser, formed by rolling supports.
  • this central axis supported at the ends can have intermediate supports that avoid this flexion.
  • the at least one fin is radially arranged.
  • the at least one fin is helically arranged.
  • the at least one fin is continuous along the entire length of the central axis, while in another preferred embodiment, the at least one fin is discontinuous.
  • the central axis has at least two longitudinal fins arranged equidistant from each other.
  • Figure 1 Shows a perspective view of the spreader for diffusion band, for a preferred embodiment of the invention.
  • the spreader (1) for diffusion band used in diffusers to extract the sugars of different raw materials through the continuous washing of the chopped raw material and deposited on the diffusion band that is proposed here, it is located on the diffusion band to sponge the bed of raw material located in the same.
  • This chiller (1) comprises a central axis (2) arranged horizontally so that it covers the total width of the diffusion band, and from which at least one longitudinal fin (3) emerges.
  • a central axis (2) arranged horizontally so that it covers the total width of the diffusion band, and from which at least one longitudinal fin (3) emerges.
  • this preferred embodiment of the invention as shown in Figure 1, from the central axis (2) a total of three fins (3) arranged radially and equidistant from each other emerge.
  • these three fins (3) are continuous along the entire length of the central axis (2). It should be noted that the number of fins will depend on the characteristics of the design, being able to make solutions with less or more fins according to interest.
  • one end (4.1) of the central shaft (2) is connected by means of connection to a gearmotor (5).
  • This gearmotor (5) is the one that generates the rotation movement of the three fins (3) on the surface of the raw material bed.
  • the three fins (3) of the chiller (1) have a width such that the end thereof, in its lowest rotational position, is comprised between the plane defined by the diffusion band and the upper plane defined by the Raw material to be treated.
  • the spreader (1) comprises means for fastening the ends of the central shaft (4.1, 4.2) to the side walls of the diffuser, formed by rolling supports (6). If necessary and in the case of central axes of great length and to avoid bending thereof, central or intermediate supports can be provided on said axis.
  • the means for connecting one of the ends (4.1) of the central shaft (2) to the gearmotor (5) are formed by a mechanical coupling.
  • the chiller (1) comprises means for blocking the operation of the diffusion band that prevent its operation when the geared motor (5) of the chiller (1) is stopped.
  • the diffusion band is prevented from continuing to operate if the gearmotor (5) of the choke (1) stops, as this could cause damage to any of the internal components of the diffuser or even in the chiller itself (1).
  • a chiller is achieved in which, thanks to its horizontal arrangement that covers the entire width of the diffusion band, with a single unit of it, it is possible to flush the entire section of raw material that circulates through the band. This results in a greater homogenization of the upper surface of raw material and therefore a lower possibility of forming preferential juice paths.
  • the number of afofadores needed is reduced and above all, the number of gearmotors used, since with a single gearmotor is sufficient. This is an important cost reduction, both investment and maintenance.
