Definitions

  • the invention relates to a method and a plant for the treatment of tobacco ribs for the production of cut tobacco for smokable items.
  • Tobacco leaves from which smokable items, especially cigarettes, as well as fine cut for
  • the self-made cigarettes are made from sheet material and Ribs that on the one hand have a very different consistency and on the other hand very have different taste properties and therefore both the technique of Tobacco preparation as well as the taste impression of the respective smokable article very much strongly, but influence differently.
  • ribs on the one hand and sheet material on the other hand in tobacco preparation on two completely separate processing lines be driven, the so-called “rib line” and the so-called “Sheet line", the respective conditioning devices, cutting devices, Sauceing devices for the application of casing, heating devices and dryers contain.
  • On the rib line is also for the purpose of rolling out the ribs in front of the A rolling mill required to cut the "CRS” (for Cut Rolled Stems) to produce rolled and cut rib pieces which are then immediately in front of the Flavor drum can be added to the sheet material.
  • CRS Cut Rolled Stems
  • DE-PS 19 21 072 is a device for increasing the degree of moisture Tobacco ribs, in which heated sauce (casing) is applied to the ribs then be heated in a heated drum. After the subsequent drying these ribs are rolled.
  • US Pat. No. 3,513,857 shows a method for treating tobacco ribs which softened and warmed with a solution of enzymes and casing and then, e.g. by Rollers or scissors are flattened. The ribs are then dried and cut. The purpose of this process is to introduce the enzyme solution into Ribs.
  • the invention is therefore based on the object of a method and a system for Treatment of tobacco ribs to create cut tobacco, in which the Disadvantages mentioned above do not occur.
  • the advantages achieved with the invention are based on the fact that by over-moistening the Ribs with a sauce and then over-drying the pipe ribs very homogeneously are moistened, which is particularly the case today when using Rib blends is a big advantage since the individual ribs are usually one have different dampening behavior and thus the usual normal Moisture did not always lead to a homogeneous treatment of the ribs. Also have these ribs have a better cutting behavior if they follow the subsequent rib process, e.g. B. the CRS method described above, which in turn leads to a less winnowing attack.
  • the ribs are expediently moist with a maximum of about 40%, in particular with a moisture content of about 35%, because of this the Energy expenditure can be further reduced.
  • the sauce is expediently applied to the uncut ribs before application a temperature between about 30 to 50 ° C, in particular to a temperature between about 40 and 45 ° C, heated to prevent the sauce from penetrating into the Ribs and thus to support homogeneous moisture penetration.
  • “Over-drying" the sauced ribs means drying on one Moisture value, which is below the usual moisture value of the untreated ribs of around 18 % lies. Particularly good results are achieved with overdrying to a moisture level of less than about 10%, preferably to a moisture of about 8%, reached the sauce to drive into the ribs.
  • the over-drying of the sauced ribs is advantageously carried out in one Steam dryer, especially a drum dryer or a Burley dryer, such as they are available in the usual tobacco preparation.
  • the sauced and over-dried ribs re-moistened, e.g. B. in a conditioning drum or the last chamber of the Burley dryer mentioned, so that they are the optimal for the subsequent rib process Have moisture.
  • untreated ribs such as those from the producing countries Cigarette manufacturers are delivered, or untreated ribs, which are caused by a Steam treatment to a humidity between about 16% and 20%, in particular about 17 % or 18% have been preconditioned.
  • preconditioned ribs are made according to a preferred embodiment stored in a closed envelope for at least 1.5 h, in particular about 2 h, so the entire rib mixture can reach this moisture value and is therefore a very homogeneous overall condition.
  • the ribs prepared in this way can either use the CRS process described above or be fed into one of the new rib processes, as used in Germany Patent application 195 43 262 or in European patent application 96 115 458.0 to be discribed.
  • the untreated ribs are optionally in a conditioning device preconditioned by steaming to a moisture level of about 17% or 18%.
  • preconditioned ribs are kept in a closed wrap for about 2 hours stored.
  • the over-dried ribs in a conditioning drum or last chamber of the Burley dryer rewet to about 33% and then the Rib cutter fed.
  • Fig. 2 shows an embodiment of a plant for the production of cut tobacco for smokable article, in which the tobacco ribs prepared according to the invention initially alone further treated and then mixed with leaf material and winnowings, as in the European patent application No. 96 115 458.0 is explained. This mixture will then then processed into tobacco strands.
  • the ribs prepared in the system according to FIG. 1, the one Moisture of about 33% have been fed to a rib cutter, the preferred one Cutting width is about 0.2 mm.
  • the pre-cut ribs are provided with casing again.
  • the pre-cut ribs are then subjected to an expansion process, as is known for example from German Patent No. 37 10 677.
  • the expanded ribs are fed to a separator that separates fluid used for expansion.
  • the separator can do this, for example be used according to European Patent No. 0 301 217.
  • the pre-cut and expanded ribs are then placed on a feed trough, which leads to a mixing container (leaf mixing box), which is also preconditioned Sheet material is fed.
  • This mixing container is a conditioning drum for upstream of the leaf material, a touch of smoke in the leaf material for cigarette production of about 17.5% and sheet material for the fine cut production a moisture of about 24% received.
  • a sauce device intended for applying casing to the sheet material.
  • a "winnowing line” is provided, which the winnowings that occur during tobacco preparation.
  • This Winnowings are conditioned in a steam tunnel that is filled with water as well Steam works, so the winnowings conditioning with a moisture of about 30% to 35% leave.
  • the conditioned winnowings are stored covered for about 2 hours and then in one Rolled roll, which has a gap width of about 0 mm.
  • the rolled and conditioned winnowings are then over another Feed channel also fed to the mixing container (leaf mixing box).
  • the mixture of ribs, leaf material and winnowings from the mixing container is made with a cutting width of about 0.85 mm for the production of cigarettes and one Cutting width of about 0.4 mm for the production of fine cuts, the The moisture of the mixture practically does not change.
  • the cut mixture of leaf material, ribs and winnowings goes into one Preheating drum, where it is moistened and heated with water and steam, so that it leaves the preheating drum with a humidity of about 22%.
  • This mixture is then dried in a hot air dryer, from which it is mixed a moisture of about 14.5% emerges and then in further steps the Tobacco preparation is fed, for example a cooling and screening drum and one Flavor drum.
  • a system without Winnowing line can be used, i.e. only pre-treated ones are used in the leaf mixing box Ribs and pretreated sheet material are mixed and then further processed fed.
