DE4334222C2 - Stick-shaped smoking product - Google Patents

Description

The invention relates to a stick-shaped smoking product having a strand-shaped core of crushed smoking tobacco, which is produced by a Sheath made from a papermaking process Tobacco foils is surrounded, according to the preamble of claim 1.

It is common knowledge tobacco foil, also called sheets made from reconstituted tobacco, according to Papierher position procedure z. B. according to US 4,182,349. In this type of procedure, a first stage stems of the tobacco plant, tobacco stems and others at Tobacco components that cannot be used in cigarette production especially fines but also tobacco leaves and with, for example, heated water or other aqueous Liquids of certain temperatures mixed or selected rule, after which by means of a sieve device of the wasserlösli Chen components-containing extract is withdrawn; in a second stage the cellulosic ingredients are optional after further intermediate stages such as homogenization, repeated Sieving or cleaning, along with fillers and others Additions to the sieve after further intermediate stages Papermaking device given. On the thus obtained The concentrated tobacco extract is applied to the raw film and this processed into the final tobacco film.

The tobacco foils produced by such an extract process have so far been used once in small chopped form for stretching used by smoking tobacco in cigarettes or cigarillos, whereby primarily those unsuitable for making cigarettes Use the fines and ribs as smokable material could. On the other hand, such tobacco foils were because of their uniform structure and better mechanical properties used as wrappers for cigarillos.

The use of tobacco foil as a binder or cover sheet for Smoking products is problematic for a number of reasons, because the tobacco foils are sensory due to the tobacco raw material insufficient and / or because of the darker color for the Consumers are not very appealing. There are numerous attempts been undertaken to remedy these disadvantages, such as for example se through enzymatic processing of the extract. Such Measures have so far been unsuccessful and have also led to Products that did not comply with legal requirements. In addition, there were considerable difficulties in this regard Lich the required properties of such tobacco films in terms of their tear resistance, their water resistance or saliva resistance or in general with regard to their Smoking properties such as porosity, burning behavior, ash stop and in particular with regard to the consumer's habit ten smoke aromas.

To remedy these disadvantages, an attempt has been made once to use the An share of tobacco stems compared to the share of tobacco leaf waste, such as tobacco grits or tobacco dust, to increase there through better processability on papermaking to allow directions with correspondingly better tear resistance lichen. The "scratchy" Ge that occurs in these tobacco foils the taste was altered by the addition of non-tobacco chemicals diminishes. On the other hand, it was suggested to use the extract from ta to treat bake-own substances accordingly or the proportion to reduce tobacco stems.

In detail according to the first mentioned procedure rensweise z. B. in accordance with LU 66 490 A a paper-like tobacco foil was milled on a Fourdrinier paper machine from 60% by weight Tobacco stems, 30 wt .-% tobacco leaf waste such as grit or dust and 10% by weight sulphate pulp produced; since this tobacco foil ge was unsatisfactory in taste turned into taste enhancement tion, based on the dry substance 5 wt .-% organometallic Chelate or complex compounds added. According to US 3,729 009 were analogous to a papermaking process Ta bak foils made of tobacco rib material on the one hand and tobacco leaf from case like tobacco dust, on the other hand, in a proportion of 3: 1 used and the addition of one of these components obtained extract in one on the dried end product related amount of 50 wt .-% provided, because of the in too elongated taste, which also accounts for most of the Ta bread crib material is based, for flavor enhancement up to 3% by weight carbamide and up to 4% by weight of a C16 to C18 fatty acid reseife, based in each case on the weight of the Ta bakrippen, admittedly. These tobacco foils can also be found under Zu set of about 20 wt .-% foreign cellulose and produced as Wrapper or binder can be used for cigarillos. Since the Addition of organometallic chelates or of carbamide and Fatty acid soaps not too tastefully acceptable either due to legal ordinances regarding permissible additives led to non-marketable products was the above suggested another alternative mentioned by z. B. according to GB 1 093 696 proposed one as a cigar top suitable tobacco foil from leaf and stem components as well To use tobacco dust in a ratio of 3: 1 and the out centrifuge the extract obtained from these components and only part of the aqueous phase is the cellulose material to feed.

Ultimately, according to EP 0 495 567 A2 for the production of a stick-shaped smoking product with a binder or cover sheet made of tobacco foil with a content of up to 5% tobacco stalks suggested that the extract only be used in a limited amount, namely not more than 20% by weight (based on the weight of the Tobacco foil). Here too she leaves taste quality or the aroma of such Product left to be desired.

All of these products have the disadvantage that once the Manufacture of tobacco foils used tobacco material to un loving flavors and the intrusive and heavy smell of secondary smoke from many smokers not ak is accepted. This taste and also the smell Impairment is given to a tobacco product with a Sheathing made from two tobacco foils, for example reinforced because this is about 20% by weight of the tobacco product make up against the core of crushed smoking tobacco and thus the taste impression of the main smoke considerably affect or reduce, as well as the odor impression of the Secondary smoke.

The invention is based on the object of providing a novel smoking product of the type mentioned at the beginning suggest, which once satisfies the typical taste expected by the smoker, that of with tobacco foil wrapped smoking products could not be achieved, and which on the other hand the Improved quality of secondary smoke. Finally, such a coated smoking product is proposed at in which the jacket formed from tobacco foils is designed in such a way with regard to the physical characteristics of the foil, that the smoking product is economically produced on conventional cigarette or cigarillo manufacturing plants and thus the requirements with regard to tear strength and elongation of such a jacket position fulfilled, furthermore smoldering speed and porosity enable control of the smoke supply chen.

To solve this problem, a smoking product is therefore proposed which, according to the main claim is designed, particularly preferred embodiments are listed in the subclaims. In particular the use of the smoking products as a new type of stick cigarillos is also proposed.

In principle, the rod-shaped smoking product according to the invention is used in the production of the tobacco foils to distinguish between two different papermaking processes, on the one hand the be described as TF-1 processes with partial extract recycling and use of tobacco stalks or of tobacco stalk or tobacco rib material and lamina tobacco material, as well as one for the Tobacco film production is a new process known as TF-2 without extract recycling and the use of exclusively lamina tobacco material, combined with an almost quantitative circulation of cold water soluble Tobacco extracts in the wire section of a paper manufacturing plant.

The tobacco foils are preferably used for the cover sheet, that is to say the outer casing of the rod-shaped Smoke product, according to the TF-1 process and for the binder, i.e. the (inner) covering of the core of the stick-shaped smoking product, manufactured according to the TF-2 process. Surprisingly, this results in a ge olfactory improvement of the secondary smoke of the product according to the invention compared to the secondary smoke of conventional, comparable products such as commercially available cigarillos. However, this does not involve the amount of secondary smoke, but only decisively improves its olfactory quality; the secondary smoke loses its obtrusive, dark, fragrant note, which is not accepted by many smokers.

However, this effect can in turn also unexpectedly be achieved with another, preferred one Embodiment according to the invention, in which exclusively tobacco films according to TF-1 are used, wherein however, considerably more tobacco extract is fed to or returned to the wrapper tobacco foil than the binder Ta bak foil. Overall, the jacket, which here consists of two layers, then contains the rod-shaped smoking product an amount of tobacco extract of more than 20% by weight based on the dry substance.

Ultimately, combinations of the tobacco foils produced by the two processes are also possible for the production of the Rod-shaped smoke product according to the invention possible, which at least partially the advantageous surprise the effects result in what makes smokers from, for example, "classic" cigarillos the switch to the invented Proper product presumably facilitated.

Tobacco foil according to TF-1

For the production of the stick-shaped smoking product according to the invention, it is essential that the after Papermaking process according to TF-1 tobacco film produced from 75 to 100% by weight essentially from Tobacco cellulose and tobacco extract consists of tobacco-own constituents, the tobacco cellulose from tobacco stalks or from cut tobacco mixture and tobacco stem or tobacco stalk material in one Ratio of 1: 1.1 to 1: 5 has been obtained while the tobacco extract is from a cut tobacco blend and tobacco stock has been obtained.

Furthermore, up to 20% by weight and preferably 8 to 14% by weight are used for the production of the tobacco films External cellulose such as softwood, hemp or flax cellulose is used. When the tobacco cellulose completely or partly from tobacco stalks, the proportion of foreign cellulose can be used without impairing the physical properties of the tobacco film are reduced accordingly.

It is advantageous if for the production of this tobacco sheet a little less than half that for the production of the Tobacco foil required tobacco material consists of a high-quality cut tobacco mixture, for example wisely made from a mixture of Virginia tobacco, Burley tobacco, Orient tobacco and the blistering ribs of Virginia tobacco consists.

With regard to tobacco cellulose, the proportion of tobacco stems required to produce the tobacco film is material slightly higher, which is necessary in view of the physical properties of the tobacco cellulose. However, the ratio of cut tobacco mixture to tobacco stems or tobacco stem material should not be used exceed a value of 1: 5, otherwise the aroma-determined smoking properties of the tobacco foil are disadvantageous to be influenced. If necessary, however, this can be done by adding tobacco flavors during the the last step of the film manufacturing process.

It is essential that in the production of the tobacco film, the extract in an amount of more than 20 wt .-% the tobacco sheet is applied to the cellulosic material obtained in this process. When the extract contains an increased proportion of a lamina tobacco extract, these will be used for the final smoking product necessary aroma components enriched.

Tobacco foil according to TF-2

This tobacco sheet made by a different papermaking process exists in terms of its tobacco mainly made of lamina tobacco material. This is based on the tobacco film in an amount of 75 to 80% by weight together with 10 to 20% by weight of long-fiber foreign cellulose and at almost complete circulation of the cold-water-soluble tobacco extracts in the wire section of a paper manufacturing plant received on this as a raw film. The usual additives such as binders, fillers, Burning-influencing agents and flavorings can be used in an amount of up to 15% by weight both at the manufacturer development of the raw film as well as later during the conditioning of this can be added.

It is advantageous if the tobacco film in its flavor-relevant tobacco mixture composition Composition of the cut tobacco mixture of the insert tobacco or the core of the rod-shaped smoke pro duktes corresponds. On the one hand, this is to achieve the desired flavor - preferably "American Blend" - required, on the other hand, with a view to simple, inexpensive production of the Rod-shaped smoking product overall advantageous, since both the coat and the tobacco mixture are made with the same tobacco mixture as well as the core can be manufactured. One can also deviate from the tobacco mixture together Change the setting of the tobacco film from the mixture composition of the insert tobacco.

To produce the tobacco film according to both TF-1 and TF-2, up to 20% by weight Foreign cellulose are added, whereby the physical properties of the tobacco film are improved.

Both tobacco films according to TF-1 and TF-2 can again be used as additives in the production Binders such as methyl cellulose, dextrins, pectins, alginates, starch, gums, amylose, carboxymethyl cellulo se, honey, corn syrup or other polysaccharides can be used. Calcium, for example, can be used as a filler carbonate or titanium dioxide can be used. Mostly alkaline earth carbohydrates are used as burn-up influencing agents nates and alkali salts of weak organic acids such as alkali citrates or acetates are used.

Tobacco own flavorings or extracts from tobacco blends can be added as flavoring substances is set, for example, by an online application of the actually finished tobacco foils by means of the Loading device from Kaymich (GB) (Kaymich applicator model FDU3 SYSM). In doing so he the aroma is preferably applied in an alcoholic solution, preferably on the inside of the tobacco foils, in order to avoid undesirable optical effects, over the entire surface or in longitudinal stripes. These subsequent slides Flavoring can be carried out both with the tobacco foil according to TF-1 and with the tobacco foil according to TF-2.
