Definitions

  • the present invention relates to an installation for drying wet composite materials.
  • the invention applies in particular to the drying of so-called cut pasta.
  • Known pasta drying devices comprise a succession of several drums supported and driven in rotation by rollers.
  • Each drum comprises a plurality of conduits or conveyor tubes arranged in a ring.
  • These tubes or pipes include a means for advancing the pasta, for example an archimedes screw or similar systems with inclined faces, these tubes are fixed relative to the drum which alone is driven in rotation. This rotation ensures the longitudinal advance of the pasta in the tubes.
  • drums are located in air-conditioned enclosures in temperature and humidity.
  • drums are aligned in separate enclosures and are driven at separate speeds, elsewhere there is only one rotary divided into several drums the whole being located in a single enclosure, nevertheless partitioned to the right of each passage of one drum to the next so as to separate the climatic zones.
  • the doughs go back and forth in two adjacent conduits so that the inlet and the outlet are located on the same side and there can then be several drums arranged not in line but side by side.
  • the object of the present invention is to produce a drying assembly at good flow rate, as short as possible, with enclosure and single drive device, while ensuring excellent quality of the product treated.
  • the subject of the invention is therefore an installation for drying wet composite materials comprising an enclosure divided into n climatic zones by partitions and inside which is located a single drum comprising means for driving in rotation, said drum being divided into as many zones as said enclosure by partitions and comprising a plurality of pipes parallel to the axis of the drum, each pipe being provided with means causing, by the rotation of the drum alone, the axial advance of the materials contained therein, said means comprising inclined surfaces having a pitch, said drum comprising means for supplying said conduits and, at the outlet, evacuation means, the conduits of the first zone of the drum being distributed in a single circular ring around the axis of the drum, characterized in that in the second zone of the drum, the pipes are divided into two concentric circular rings, in that the name bre of pipes of the inner circular ring is equal to qq being an integer and p being divisible by q, the number of pipes of the outer circular ring being equal to% and in that at the outlet of the pipes of the first zone, the content of
  • said drum comprises three zones, the third zone comprising the same number of pipes as the second zone and distributed in the same manner, the materials making, in this third zone a triple path according to a outward journey, a return and a new go in three consecutive lines.
  • the step of advancement of the means allowing the axial advancement of the materials is smaller in the third zone than that of the second zone.
  • the installation for drying short pasta comprises an enclosure 1 divided into three climatic zones 2, 3 and 4 by two partitions 5 and 6.
  • Each climatic zone is provided at its upper part with a heating battery 7, constituted for example by finned tubes traversed by hot water.
  • a fan 8 driven in rotation by a motor 9 sucks through the battery 7 and discharges downwards towards a longitudinal drum 10 of axis A supported and driven in rotation by rollers 11.
  • the drum 10 is also divided into three corresponding zones to the three zones 2, 3, 4 of the enclosure 1, by internal partitions 12 and 13.
  • the enclosure 1 also includes, for each climatic zone, an opening 14 in the low position for the entry of air and a sheath 15 , provided with a tilting flap 16, is situated in the upper part on the opposite face for the extraction of the air laden with moisture after passing over the pastes situated in the drum 10.
  • the drum 10 comprises a plurality of pipes parallel to the axis ⁇ of the drum.
  • the pipes 17 are distributed according to two concentric circular rings: pipes 18 on the crown and outside and pipes 19 on the inside crown (see fig. 4).
  • FIG. 8 shows the diagram for the passage of the pasta in the various pipes from the entry into the drum to the exit during the rotation of the drum.
  • the pasta advances in the conduits 17 then passes into the second zone 3 in the conduits 19 of the inner ring, each conduit 19 receiving the contents of three conduits 17.
  • the contents of the pipes 19 flows into one out of two of the pipes 18 to travel in the second zone in the opposite direction then finally a new go in a new pipe 18 to end up in the third zone 4 in one out of two of the pipes 20, return to a pipe 20 neighbor then new go to the pipes 21 of the internal crown.
  • lines 17 to 21 are for example constituted by archimedes screws ensuring the advancement of the pasta by the only rotation of the drum.
  • a neighboring advancement system known per se is used, based on inclined surfaces having a pitch as shown in the figure, 7.
  • the pipe has two solid faces 22 and 23 and two mesh faces 24 and 25 allowing the passage of air in the pipes.
  • the advancement system comprises two series of offset parallel faces: 26 and 27 and inclined faces 28 and 29 connecting each face 27 to two neighboring faces of the series of faces 26.
  • the faces 28 and 29 are half the height of the faces 26 and 27.
  • the faces 28 connect the faces 27 and 26 to their upper part and the faces 29 to their lower part.
  • the pasta is introduced into the drum 10 by an introduction chute 30 which pours the pasta into a collector 31 which distributes it in the various conduits 17 during the rotation of the drum. Similarly, at the outlet of the drum, the pasta leaves the pipes 21 of the inner ring in a collection 32 which pours into a discharge chute 33.
