The present invention relates to a smokable filler for Smoking articles, in particular to agglomerated tobacco filler and Smoking products with this filler.

When the primary and secondary processing of tobacco formed dust and tobacco fines, which on an industrial scale is not used. In tobacco stuff usually contains a large number of abrasive silicon dioxide, which makes it unsuitable for further processing in machines for cutting or grinding tobacco. Not be further processed tobacco fines usually just goes to waste. On purely economic and environmental reasons, any reduction of waste requiring special disposal, at the present time is highly desirable. Therefore, any process, allowing maximum use of waste tobacco is without a doubt cost-effective.

Currently known papermaking techniques used for the manufacture of reconstituted tobacco, should for reasons of efficiency and cost of the final product to have a high performance. Due to the high cost of such paper technologies, their use in relatively small about the Birmingham production is economically disadvantageous. So any way to use tobacco waste without the use of expensive equipment must be economically very advantageous.

Tobacco dust has long been used in the manufacture of reconstituted tobacco, for example in the manufacture of sheet material from reconstituted tobacco and cast or extruded sheet of tobacco material, previously described in patents GB 2201081 and GB 2201080. Made of processed tobacco dust material added to tobacco products in the amount up to 30 wt.% in terms of a lot of the smokable material of the tobacco rod. Some species such tobacco products, in particular manufactured by casting or extrusion of a sheet of tobacco material, possess a poor technological properties and are prone to degradation during subsequent processing. This is made from reconstituted tobacco, tobacco products-stuffing, usually ranging from 2.5 to 3.5 cm3/g, significantly lower than that of rolling tobacco (5 to 6 cm3/g) and reconstituted tobacco sheet (from 8.0 to 8.5 cm3/g).

Currently, there are several ways to use agglomerated tobacco dust and stuff for the manufacture of various tobacco products from reconstituted tobacco.

In the US 3894544 described a method of manufacturing a tobacco material the material of reconstituted tobacco, which of the moistened and mixed with each other veins of leaf tobacco and waste get doughy mass, which is then formed into shaped leaves patterns. These shaped leaves patterns stretch under pressure to get the individual records of tobacco.

B DE 3312159 described method of manufacture is similar to leaf tobacco tobacco material from a mixture of tobacco particles in detail, fibers, water and a binder, after which the granulation and rolled to the required thickness can be immediately added to the cut tobacco.

In the US 4341228 described the way in which from the treated mixture of tobacco dust and a binder receive agglomerated fibers. Agglomerated fibers are mixed with parts of tobacco with obtaining a slurry from which the paper machine is formed into a sheet. The resulting sheet is dried and milled. As a result, the agglomerated particles of tobacco dust, that its size does not pass through a sieve with mesh size 56 mesh, preferably do not pass through a sieve with a mesh size of 20 mesh (sieve with holes with a diameter of 0.84 mm).

Each of these methods of manufacture of tobacco products requires the use of an appropriate binder, which imparts obtained from reconstituted tobacco products to the required density.

The purpose of this image is the shadow is the use of tobacco waste and in particular, do not have at present no commercial value tobacco dust for the production of agglomerated tobacco, which according to the degree of packing is not substantively different from fine-cut tobacco.

Another objective of the present invention consisted in the development of a method for manufacturing agglomerated tobacco with the use of waste with a high content of silicon dioxide, which is not currently used in the manufacture of conventional tobacco products from reconstituted tobacco due to the high abrasive properties of silicon dioxide and heavy wear on the further stages of the process mills and cutting machines.

Another objective of the present invention consisted in the development of a method for manufacturing agglomerated tobacco, which can be used in Smoking products instead of other tobacco reconstituted tobacco material from or together with him and that when it is used as filler density padding is essentially not different from fine-cut tobacco.

The present invention was further in the development of a method for manufacturing agglomerated tobacco filler, which has a fairly good processing properties and reduced brittleness and therefore can directly, without any additional about the processing used in Smoking products.

Another objective of the present invention consisted in the development of a method for manufacturing agglomerated tobacco filler method of fluidization at low operating temperature by only a single operation.

Found above the term "stuffing" means measured in cubic centimeters volume that can be filled with 1 gram of material. The pistons gaskets measured by a densitometer of Borgwaldt (DD60A), in which a sample of material of a certain mass is poured into a stainless cylinder of known dimensions, for example in a cylinder of radius 3 cm, and then within 30 pressed by the piston of known mass (for example, a piston mass of 1 kg). According to measured height of the compacted material calculate its volume. This volume divided by the mass of the sample and the results obtained are expressed in cm3/, In the examples below, the stuffing was determined using the above device.

When determining volumetric (bulk) density measure the mass of material (in grams)present in a specific volume (cm3). Quotient of the mass to the volume is equal to the bulk density of the material, expressed in g/cm3.

In the present invention proposes a solid agglomerated tobacco filler, which retains its quality during processing. This fact is especially important in the light of possible shredding tobacco material on the stages of primary and secondary processing. The strength of the agglomerated tobacco filler was determined by the method described below in example 3. The strength of the filler was evaluated by the amount of filler lost during grinding, i.e. resulting from grinding to reduce the size of its granules. The loss of agglomerated material was determined as the difference between the percentage of agglomerated tobacco filler, the OST is located on sieves with mesh size of more than 710 μm, prior to its reduction and the percentage of agglomerated tobacco filler remaining on sieves with mesh size of more than 710 μm after grinding.

FIELD: tobacco products.

SUBSTANCE: methods proposed refer to reconstituted leaf tobacco production, as well as to production of modified reconstituted leaf tobacco. The methods are designed for cigarette manufacturing. One of the version refers to method of reconstituted leaf tobacco with binder production. The method implies production of suspension from tobacco and binder in given correlation. Preliminarily produced leaf of reconstituted tobacco, containing given quantity of wood paste, is enveloped with the suspension obtained. The suspension is complemented with a flavouring agent. The reconstituted leaf tobacco is supplemented with wetting reagent. A leaf of reconstituted tobacco is sliced into stripes. Several such stripes are placed into cigarette so that the stripes are adjacent to tobacco core. The other reconstituted leaf tobacco production version implies manufacturing of suspension from binder, wetting reagent, tobacco and flavouring agent, following defined proportions. The suspension is produced by sequential dispersion of tobacco, binder, wetting reagent and flavouring agent in water solvent. Then leaf production technological procedure is as described above. It also refers to cigarette, containing tobacco core, which is wrapped into outer envelopment, as well as to incomplete inner envelopment, presented by one or several stripes, made from reconstituted tobacco leaf. The inner envelopment is placed along the tobacco core, between the latter and outer envelopment. It also refers to reconstituted leaf tobacco, containing wood paste, binder and tobacco in defined proportion. The method of modified reconstituted leaf tobacco production includes the following operations. First, tobacco particle suspension is prepared in water solvent. The suspension obtained is then subjected to extraction processing at temperature of approximately 160°F for a period of approximately 30 minutes. Then the suspension is divided into extract with components, soluble in water, and solid fraction, which is mixed with wood paste and formed into leaf of reconstituted tobacco, using Fourdrinier machine. The extract is centrifugated, concentrated, supplemented with first binder and wetting reagent, applied to leaf of reconstituted tobacco and dried. Afterwards, the leaf is processed as described above.
