Definitions

  • the invention relates to an apparatus for producing filters with a flavor for products of the tobacco processing industry having the features of the preamble of claim 1.
  • the filters are produced in a continuous strand from a so-called filter tow into which a flavor carrier soaked in or wetted with the flavor is introduced. It is also conceivable to produce the filters in several parallel strands, preferably with a production of the filters in two parallel strands in a double-strand machine.
  • the filter tow itself is made, for example, from a cellulose acetate which is treated with a means for dissolving the acetate fibers, in particular triacetin.
  • the flavor carrier itself may be formed, for example, by an endless carrier such as a cotton thread, an acetate thread, an absorbent tape or the like, which is soaked with a flavor and / or wetted and continuously introduced into the strand of filter material.
  • the flavoring agent may be, for example, menthol, which should give the smoking person a fresh taste.
  • the menthol is applied in liquid form as a hot menthol on the flavor carrier and has a temperature between 40 and 45 degrees Celsius at the time of application.
  • the temperature of the menthol decreases, there is a risk that the viscosity of the menthol increases and the menthol increases its flowability important for the distribution loses.
  • the temperature of menthol exceeds an upper limit, for example, 80 degrees, there is a risk that the taste properties of menthol will change. Up to a temperature of 70 degrees, a preservation of the taste characteristics can be assured.
  • the invention has for its object to provide a device with the filter with the largest possible amount of flavor in the most uniform distribution of the flavor in the longitudinal direction of the filter and in the cross-sectional area of the filter can be made.
  • a mixing chamber in which the flavor is applied in a supersaturated amount to the flavor carrier, and that between the feeder and the mixing chamber, a distribution portion is provided through which the flavor carrier with the applied flavoring passed is.
  • the flavor is according to the invention in a supersaturated amount, that is applied in an amount which is deliberately such that the flavor carrier can not absorb them completely, and the flavor adheres to the outer surface of the flavor carrier in a layer.
  • a flavor carrier can be loaded beyond its saturation limit with flavor and insert in the strand. Not only can the flavor penetrate to fill the free pore volume of a flavor carrier and reach a saturation limit of the flavor carrier, but it can also be loaded onto the flavor carrier.
  • the flavor is virtually entrained by the movement of the flavor carrier, without dripping from the flavor carrier. Because of the distribution portion provided between the mixing chamber and the feeder, the flavor on the surface of the flavor carrier is evenly distributed on the taste carrier due to the inertial forces acting through the speed of the flavor carrier and acceleration of the flavor, so that the flavor decreases adhering to the flavor carrier when passing through the distribution section as far as possible without drops or sections of greater layer thickness. This is the flavor carrier with the flavor deliberately moved over a longer distance in the distribution section at high speed, so that the flavoring has sufficient time to distribute itself on the flavor carrier due to the acting inertial forces.
  • the distribution section is therefore to be regarded as a section in which the flavoring agent can be distributed evenly over a longer distance under the effect of the lowest possible asymmetric radial forces on the flavor carrier.
  • the distribution section and the mixing chamber can also be combined in the form of a common component, so that a longer portion of the passage channel in the mixing chamber acts as a distribution section, or the flavor is applied in the distribution section. Further, the flavor may also be applied in addition to the application in the mixing chamber in the distribution section.
  • an amount of flavoring material can be kept, or the distribution section can be used as an intermediate buffer, in that buffering of excess flavoring material and subsequently, if necessary, can be applied again to the flavoring agent.
  • the distribution section should have a length of at least 20 mm, preferably at least 75 mm, particularly preferably at least 150 mm and 200 mm, for example, so that the independently brought about homogenization process and the flavor carrier in the sequence uniformly impregnated with the flavor or . is wetted.
  • the flavor is applied heated, and the distribution section has a heater.
  • the heater allows a needs-based Adjust the viscosity.
  • the heater can be used to prevent the hot applied flavor from cooling in the distribution section, thereby increasing the viscosity and causing the flavor to lose its important flowability for the out-of-balance effect.
  • the flavor is applied at a temperature of 40 to 70 degrees Celsius, preferably up to 60 degrees and particularly preferably up to 50 degrees Celsius, which then z. is maintained by a preferably the distribution section associated, controlled in the heating power heater.
  • the heating device is preferably regulated as a function of the temperature of the flavor adhering to the flavor carrier prior to introduction into the filter material.
  • the principle is that by applying the flavor with low temperatures low heating and gentle treatment of the flavor can be made possible.
  • the flavoring agent is a meltable additive, in particular hot menthol, and is applied with a fluidity-causing temperature of 40 to 70 degrees Celsius, preferably up to 60 degrees and particularly preferably up to 50 degrees Celsius.
  • the distribution section comprises a tube or hose section which is closed on the circumference, in particular being formed by the latter, which comprises the flavor carrier.
  • the flavor carrier is thereby with the applied flavoring transported together in a chamber-like space, which has only on the inlet side and on the outlet side in each case an opening for insertion and removal of the flavor carrier. This can prevent the flavor from escaping into the environment during the distribution process, instead of penetrating the flavor carrier or evenly distributing on the outer circumference of the flavor carrier, especially in an amount exceeding a saturation limit.
  • optimal for the distribution of the flavor temperature and / or vapor conditions can be created.
  • a device for applying a sealing air is provided on the inlet side of the mixing chamber.
  • the blocking air can be prevented that the flavor rises despite the supersaturated order against the direction of movement in or on the flavor carrier and escapes from the mixing chamber.
  • the removal of the flavor or the wetting or loading of the flavor carrier with the flavor can be made particularly effective by the flavor in the mixing chamber at an angle of 10 to 75 degrees, preferably 40 to 60 degrees, to the longitudinal axis of the flavor carrier towards the movement of the flavor carrier is applied.
  • the flavor is thereby applied to the flavor carrier with a velocity directed in the direction of travel of the flavor carrier.
  • the flavor itself is deflected less, whereby the asymmetric forces acting in the flavor are lower, and the flavor is subsequently distributed more evenly on the flavor carrier.
  • the removal of the flavor by the flavor carrier favors, since the flavor is less accelerated even when applied. Due to the lower acceleration of the flavor, the likelihood of the continuous flow of flavoring being reduced and the flavoring being applied in portions in a very uneven distribution is reduced.
  • the flavor carrier is guided at least upstream in the mixing chamber in a passageway which is narrowed by means of a passage narrowing the passage sleeve.
  • a passage narrowing the passage sleeve By means of the passage narrowed by means of the sleeve, the escape of the flavor from the mixing chamber against the direction of movement of the flavor carrier can be further reduced and, in addition, the guidance of the flavor carrier can be improved, in particular before the flavor is applied.
  • the sleeve can be formed both by a separate part and by an integrally formed on the passage channel paragraph.
  • the sleeve should have an inner diameter which minimally 1.5 times, preferably 2 to 20 times, more preferably 2.5 to 10 times and especially 3.0 to 7 times the outer diameter of the flavor carrier corresponds.
  • the flavor carrier is supplied to the filter material from below. This solution has the advantage that when the device is switched off, the flavor does not drip down the flavor carrier or down from the mixing chamber onto the filter strand and / or the subsequent assembly, such as the distribution section, thereby contaminating the device especially can cause problems in a subsequent startup of the device.
  • the strand speed of the flavor carrier is 200 m / min, preferably between 250 to 700 m / min, more preferably between 400 to 650 m / min, in particular 600 m / min.
  • the flavor is applied in an amount of from 200 mg / m to 900 mg / m, preferably from 300 mg / m to 850 mg / m, more preferably from 580 mg / m to 660 mg / m.
  • Surplus flavor may form a kind of bonding layer between the filter material and flavor carrier, wherein the adhesive effect of the tie layer may lead to a positive wedging in the fibers of the filter material, for example a resolidifying flavor, which has previously been melted for application.
  • a device which is a strand-shaped endless flavor carrier 1, for example in the form of a cotton thread via a deflection device 10 is supplied. Further, the device is fed to an endless strand 5 of a filter material. The strand 5 of the filter material is fed in a known manner via a funnel device 6 of a garniture consisting of a format base 8 and one or more upper format parts 7, in which the strand 5 is compressed to a smaller diameter and is fixed in shape with a wrapping strip. The strand 5 is then in a subsequent processing station cut into single or double-length filters of a predetermined length.
  • a second bore 12 is also provided, which is aligned at an angle A of about 40 degrees to the passage 13 and opens into the passageway 13.
  • a distribution portion 3 in the form of a hose provided with a heater, which is fastened with a fitting in a thread on the output side of the through-channel 13.
  • the flavor carrier 1 is introduced from above at an oblique angle relative to the transport direction of the strand 5 through the tube of the device 9 in the passageway 13 of the mixing chamber 2.
  • the flavor carrier 1 is guided in the sleeve 16, which has an inner diameter which is at least 1.5 times, preferably 2 to 20 times, particularly preferably 2.5 to 10 times and in particular 3.0 to 7 times the outer diameter of the flavor carrier 1 corresponds.
  • a metering device 11 is connected, which gives up a metered amount of a flavor 17 through the bore 12 on the guided in the passageway 13 flavor carrier 1.
  • the amount of flavoring agent 17 is 200 mg / m to 900 mg / m, preferably from 300 mg / m to 850 mg / m, more preferably from 580 mg / m to 660 mg / m when operating at a strand speed of flavor carrier 1 of 200 m / min, preferably between 250 to 700 m / min, more preferably between 400 to 650 m / min, in particular of 600 m / min and thus corresponds to a supersaturated amount, which can not be absorbed by the flavor carrier 1 consciously.
  • the addition of the flavor 17 is reduced, so that in turn the desired loading of the flavor carrier 1 is realized, which is still a supersaturated amount in the sense of the invention. Since the flavor carrier 1 is transported by the endless strand 5 of the filter material, the strand speed of the flavor carrier 1 also corresponds to the strand speed of the strand 5. The addition of the flavor 17 is controlled depending on the desired loading and strand speed being traveled.
  • the flavor 17 Due to the aligned at an angle of 40 degrees to the passage 13 bore 12 of the flavor 17 is given with a direction of movement of the flavor carrier 1 rectified component of movement on the flavor carrier 1.
  • the flavor 17 is thereby less deflected and accelerated in the task on the flavor carrier 1, which is positive for the subsequent distribution effect, since the flavor 17 is thereby subject to lower forces during application, and subsequently in a more uniform distribution of the flavor carrier 1 adheres.
  • the directed application of the flavoring agent 17 can reduce the likelihood that the flavoring agent 17 applied in the supersaturated amount rises in the direction of the device 9 counter to the direction of movement on the flavor carrier 1.
  • the flavor carrier 1 impregnated or wetted with the supersaturated amount of the flavorant 17 is then passed through the distribution section 3, which in the illustrated embodiment is formed by a heated flexible hose with a length of 200 mm.
  • the flavor 17 is distributed on the flavor carrier 1 to a uniform layer due to the speed and the acting inertial forces, so that the flavor 17 in spite of the supersaturated amount after the exit of the flavor carrier 1 from the distribution section 3 in a layer without drops and without Sections of larger or different thicknesses adheres to the flavor carrier 1. It is important that the flavor carrier 1 in the distribution section 3 is as far as possible not deflected so that no uneven radial forces act on the flavor 17 distributed over the circumference of the flavor carrier 1.
  • the distribution section forms, apart from the supply and the export opening for the flavor carrier 1, a closed chamber-like space in which there is a temperature which is slightly higher than the temperature of the flavor 17, so that the flavoring substance 17 on passing through the tube no case cools.
  • the flavor 17 can be heated by a higher temperature in the tube even in addition to the surface, whereby the distribution effect of the flavor 17 to be achieved can be further promoted, as a result the flowability of the flavorant 17 adhering to the flavor carrier 1 on the outside can be further improved.
  • vapor flavor vapor ratios may also be established which, firstly, prevent the flavor 17 from continuously evaporating and, secondly, provide improved heat transfer to the flavor 17.
  • the flavor carrier 1 supersaturated with the flavor 17 is then introduced into the continuous strand 5 of the filter material via a feeder 4 in the form of a finger in the form of a finger in front of the pattern in a section downstream of the funneling device 6 in relation to FIG Transport direction of the strand 5.
  • the flavor carrier 1 is supersaturated in the already precompressed in the hopper 6 strand 5 of the filter material introduced, in such a way that it comes to lie approximately in the middle of the strand 5.
  • the strand 5 is transported further with the inserted flavor carrier 1 via a resting on the format base 8, driven conveyor belt and further compressed on a two-part in this case format upper part 7 with the format parts 7a and 7b different shape and fixed by a peripheral glued wrapper strip.
  • the flavoring agent 17 despite the higher proportion in a uniform distribution in the strand 5 of the filter material, both in Longitudinal and distributed over the cross-sectional area is present. This is because the flavor 17 after dispensing in the mixing chamber 2 in the distribution section 3 was uniformly distributed on the flavor carrier 1 by the flavor carrier 1 over a free distance of at least 20 mm, preferably at least 75 mm, more preferably at least 150 mm and, for example, 200 mm was transported substantially without deflection. This improved distribution of the flavorant 17 present in a larger amount results in the flavorant 17 entering the filter material in a greater amount with a more even distribution.
  • the flavor carrier 1 is heated with the applied flavor 17 in the distribution portion 3, so that the flavor 17 does not cool and thereby loses its flowability, so that the distribution effect is not inhibited by a possible cooling. Namely, it has been found that the flowability of the flavor 17 is very temperature-dependent, such that the viscosity of the flavor 1 increases with decreasing temperature and fluidity thereby decreases.
