Definitions

  • the invention relates to a method for producing cut tobacco from relatively dry tobacco from sheet material or ribs, which is pressed into bales which are heated dielectrically (by high-frequency electrical fields or microwaves).
  • the invention also relates to a system for producing cut tobacco from relatively dry tobacco from sheet material or ribs, which is pressed into bales, with a treatment arrangement for dielectric heating of the tobacco by means of microwaves or high-frequency electrical fields.
  • tobacco After harvesting, tobacco is dried relatively strongly, ie to a residual moisture content of about 8-11%, and is usually pressed for dispatch in cuboid or cylindrical bales or packages, although other forms of compression are also possible.
  • the tobacco can be pure pre-stripped leaf material (without essential rib parts); the ribs removed before drying, which are processed separately and mixed again with the leaf tobacco, can also be pressed and shipped in a dry state.
  • the compressed and relatively dry tobacco can also be stored for a long time in this condition. Should this relatively dry tobacco be used for smoking products, e.g. As cigarettes are processed, it is necessary in the known processing methods to separate and separate the individual sheets (or sheet pieces) or ribs (or rib pieces) from one another in the pressed bales.
  • the tobacco is compressed very strongly by means of converging press chains (one speaks of a "tobacco cake") before slices of fiber can be cut off on a mouthpiece by rotating knives.
  • the cut tobacco must then be dried again to the processing moisture of 12.5 to 13.5%, in which he z. B. is processed on a cigarette machine to cigarettes.
  • GB-OS 2 187 632 describes a method and a plant for cutting tobacco, wherein bales of relatively dry tobacco are heated by means of microwaves and then fed to a tobacco cutter before cooling.
  • the bales (or bale pieces thereof) have the same size in terms of width and height, for which purpose the mostly larger shipping bales first have to be divided into suitable sections.
  • the object on which the invention is based is to further develop the known method such that the tobacco does not have to be conveyed to the tobacco cutter in suitable sections, the question of remaining pieces arising, but can be supplied without this restriction.
  • this is achieved in that the relatively dry tobacco in the heated bale or pieces thereof (bale pieces) is subjected to a dissolving step before cooling and the loosened tobacco is fed to a tobacco cutter and cut.
  • Dielectric heating increases the suppleness of the pressed tobacco parts in that crystals in and on the parts dissolve.
  • the term "before cooling” therefore means further processing at a time when the crystals have not yet formed again.
  • the term "loosening" of the tobacco in the heated bale or a part thereof does not mean that all or most of the leaves are detached from the adjacent leaves. Although this may be the case, it is sufficient for the invention that the bales are broken up to such an extent that the single sheets and / or smaller or larger lumps thereof the press chamber of the tobacco cutter before it Fill the knives sufficiently homogeneously.
  • the tobacco is advantageously heated above 30 ° C.
  • a particularly good detachment of the tobacco parts from one another is at temperatures above 60 ° C, z. B. between 60 ° C and 90 ° C reached.
  • the invention can also solve the problem of continuously loading tobacco cutters.
  • the bales or bale pieces, the z. B. have passed through a continuously operating microwave treatment system, then dissolved immediately after leaving the treatment system, ie the tobacco in the bale is sufficiently isolated.
  • the loosened tobacco is conveyed to the tobacco cutter in a relatively dry state, that is, with its shipping moisture content of 8-11%, and is increasingly pressed by its press chains and cut from rotating knives to tobacco fibers in the mouthpiece area.
  • the heated tobacco bales can also be fed to a so-called release additive after leaving the treatment system, which converts the bale into a continuous flow when released, which is fed to the detection area of the tobacco cutter.
  • a measuring arrangement for the amount of dissolved tobacco located there can be arranged in the detection area.
  • a corresponding quantity-dependent measurement signal can control the quantity flow of the warm, dissolved tobacco supplied in the detection area in the event that the quantity of tobacco deviates from a desired value in such a way that the quantity is kept at the desired value.
  • control of the mass flow can be connected to the dissolving process itself in such a way that if a large mass flow is required, a lot of tobacco is dissolved per unit of time and vice versa. This minimizes the undesired cooling of the dissolved tobacco.
  • the warm and dry cut tobacco (leaf cut, rib cut, mixture of leaf and rib cut) leaving the tobacco cutter is, preferably immediately afterwards, d. H. before cooling, moistened, which can be done in a conventional manner in a wet drum, as z. Described in U.S. Patent 4,054,145 or 3,948,277.
  • the cut tobacco is moistened in a so-called steam tunnel, which has a vibrating delivery channel with steam inlets and z. B. is described in US-PS 4 004 594 or GB-OS 2 138 666.
  • the tobacco moisture can be increased in order to minimize the amount of energy used until the processing moisture (12 to 13.5%), which the tobacco has after cooling to room temperature and with which it is processed in cigarette machines. However, it can also be moistened to higher degrees of moisture (over 20%) in order to increase its filling power, after which it is dried down to the processing moisture.
  • the moistening preferably takes place immediately after cutting, so that the relatively dry but still warm cut tobacco reaches the dampening device before it has cooled down.
  • the cut tobacco can be flavored, e.g. B. sauce and / or flavor. If it is Burley tobacco, the temperature can be raised to ammonia expulsion levels.
  • the tobacco fibers of different types or types of tobacco can be mixed with one another, for which purpose a system according to US Pat. No. 4,116,203 is suitable.
  • the plant described at the outset, in which the method according to the invention can be implemented, is characterized by a release device for releasing the relatively dry tobacco into the heated bales or pieces thereof and by a conveyor for conveying the heated dissolved tobacco to a tobacco cutter in which the dissolved heated tobacco is cut.
  • Microwave treatment systems are particularly suitable for dielectric heating. However, treatment systems which work with electrical high-frequency fields (capacitor fields) are also suitable. B. in the megahertz range (z. B. in the range of 10 - 20 MHz) can be operated.
  • FIG. 1 shows a treatment plant for tobacco, which has a microwave treatment arrangement 1, a release device 5, a tobacco cutter 2 and a dampening device 3 in succession in the conveying direction of the tobacco.
  • the microwave treatment arrangement is described in detail in U.S. Patent 4,799,501. It has a conveyor belt 8 guided over rollers 6 and 7, which can be driven by a drive (gear 9) and on which bales or pieces of bale 10 made of relatively dry (approx. 8 to 11% relative humidity), pressed tobacco, as it stands in the tobacco preparation is at the beginning of the treatment after shipping and storage.
  • the treatment is shown for leaf tobacco, although rib tobacco can also be processed with corresponding known modifications. 11a ...
  • the bale pieces 10 guided along the arrow 14 through the treatment chamber 12 are heated to temperatures of at least 30 ° C., preferably between 60 and 90 ° C., the inside of the bale also being heated due to the microwaves passing through the bale pieces.
  • the plant can be controlled with respect to the bale temperatures by controlling the power of microwave generators in dependence on temperature sensors, not shown, e.g. B. by switching on or off microwave generators (magnetrons) or power variation of so-called klystrons.
  • the bale pieces 10 are fed to the releasing device 5, in which a belt 15, which is equipped with pins 15a and is driven to circulate and which is guided over rollers 15b and 15c, continuously removes warm tobacco from the foremost heated bale 10a and towards it of the arrow 15d at an angle upwards.
  • the dissolved warm tobacco 20 goes directly into the detection area A des Tobacco cutter 2, the converging press chains 16 and 17, which form the press channel 18 (press section), can also be driven by the gear 9.
  • the loosened tobacco 20 is conveyed by the converging press chains 16, 17 from the detection area A to a mouthpiece 21, the movable upper part 22 of which, together with the upper press chain 16, is loaded by a force element 23, so that the tobacco is strongly compressed in the mouthpiece area.
  • the knives 24 of a rotating knife drum 26 successively cut homogeneous slices of fibrous cut tobacco 27, which forms a cut tobacco stream 27a of warm, relatively dry tobacco.
  • the cut tobacco stream 27a passes via a conveyor belt 28 directly to the dampening device 3, in which the cut tobacco is moistened.
  • a dampening device are suitable drums, such as are described, for example, in US Pat. Nos. 4,054,145 and 3,948,277. But vibration channels with steam and / or water supply are also suitable, in which the tobacco can be moistened quickly, gently and intensively.
  • Such a channel is e.g. B. in US-PS 4 004 594 or GB-OS 2 138 666 described.
  • the last-mentioned vibration channel works with steam of higher pressure, through which the tobacco can be humidified to processing moisture, whereby it can reach high temperatures of over 100 ° C in the desired manner. If he should also be moistened, water, z. B. heated or hot water supplied.
  • Figure 2 shows a variant of the release device 5. This is not, as in Figure 1, placed in the conveyor path between the microwave treatment arrangement 1 and the tobacco cutter 2; rather, it has a bale container 41 with a bottom band 42 which is guided over rollers 43, 44. Roller 44 can be driven by a drive motor 46, which can be controlled by a control amplifier 47 in the sense of higher or lower speeds.
  • the pin strap 15 is mechanically coupled to the base strap 42.
  • a measuring arrangement 48 e.g. B. a photoelectronic level sensor, emits a signal when the amount of dissolved warm tobacco 20 in the detection area A of the tobacco cutter 2 deviates from a desired value.
  • the signal then, depending on the sign of the deviation, controls the drive motor 46 so that the desired quantity in the detection area A is maintained again. It is also important in the arrangement of FIG. 2 that tobacco is removed from the bale 10a while it is still in the heated state. The removed tobacco 20 must also be fed to the tobacco cutter 2 when warm.
  • the treatment plant described above is suitable for processing relatively dry, pressed leaf tobacco of a kind (e.g. Burley tobacco) into cut tobacco.
  • cut tobacco can be used for other types of tobacco (e.g. Virginia tobacco and Orient tobacco, which are used for conventional tobacco blends ) from relatively dry, pressed leaf tobacco.
