Description

Improvements relating to Smokable Filler Materials The subject invention relates to smokable filler materials and more particularly to agglomerated tobacco filler material, and smoking articles incorporating such material.
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
As a result of primary and secondary processing, dust and fines of no further commercial use are produced. The fine tobacco may have a high silica content, which because of its abrasive nature renders the fine tobacco less than desirable for use in a further process which utilises cutting or grinding apparatus. The fine tobacco waste that cannot currently be processed further is taken for landfill. In the current economic climate reduction of landfill is desirable for financial and environmental reasons. Any process which maximises tobacco waste usage has great benefit.
Paper-making processes currently used for making reconstituted tobacco products need a high throughput to make them efficient and cost effective. Paper-making processes may not be suitable for certain factories due to lack of expensive apparatus or low volume of materials.
Any process utilising waste without the need for high cost apparatus would be of significant benefit.
WO 03/055337 PCT/GB02/05899 2 The utilisation of some tobacco dust in reconstituted products is long since known, for example in products such as reconstituted sheet material, bandcast sheet and extrusion products as previously described in our patents GB 2201081 and GB 2201080. Such products utilise processed tobacco dust and can be incorporated into smoking articles at inclusion levels of up to 30% by weight of material in the tobacco rod. Some of these products, in particular bandcast sheet and products of extrusion, have poor handling properties and are susceptible to degradation during further processing.
Such reconstituted products have fill values in the range of 2.5cm 3 /g to 3.5cm 3 these fill values being substantially lower than those of cut tobacco (5cm 3 /g to 6cm 3 and reconstituted tobacco sheet (8.Ocm 3 /g to 3 The agglomeration of tobacco dust and fines has been previously proposed as a means of generating reconstituted tobacco products.
In US 3,894,544 a process for the production of reconstituted tobacco material is described in which ribs and wastes are moistened with a liquid, kneaded together to form a dough-like mass which is then shaped to form leaf-like structures. The leaf-like structures are spread under pressure to form individual flakes.
3 DE 3 312 159 describes a method of manufacture for tobacco leaf-like material by pelletising a mixture of fine tobacco particles, fibres, water and binder and rolling out the pellets to a desired thickness to give a material that may be added directly to cut tobacco.
US 4,341,228 describes a process in which tobacco dust is mixed with a bonding material, the mixture is then treated so as to form agglomerated fibres. These agglomerated fibres are mixed with tobacco-parts in a slurry and formed into a sheet by means of a paper-making process. That sheet is then dried and shredded. The agglomerated tobacco dust particles are of a size such that they do not pass through a 56 mesh screen, and preferably do not pass through a 20 mesh (0.84mm) screen.
Each of these methods results in a product through compaction with added binders thereby resulting in a dense reconstituted tobacco product.
It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
It is an object of the present invention, at least in a preferred form, to provide an agglomerated tobacco product in which tobacco waste, and in particular tobacco dust currently of no commercial value may be utilised to give a product having a fill value substantially similar to that of cut tobacco.
It is a further object of a preferred form of the present invention to provide an agglomerated tobacco product which can use waste of high silica content, such waste usually being of no commercial value in conventional reconstituted tobacco products and processes due to silica being highly abrasive to grinders and cutters used in further processing.
1 IN 4 It is an even further object of the present invention, at least in a preferred form, to provide an agglomerated tobacco product capable of being used instead of, or in 00oO combination with, other reconstituted tobacco material in smoking articles, wherein the fill value of the agglomerated tobacco filler material is substantially similar to that of cut 5 tobacco.
oO It is a yet further object of a preferred form of the present invention to provide an agglomerated tobacco filler material having acceptable handling properties and reduced ri frangibility such that the product may be directly incorporated into smoking articles without the need for further processing.
Preferred embodiments of the present invention also provide an agglomerated tobacco filler material that is produced using fluidised bed technology and low process temperatures in a one-step procedure.
As referred to herein, 'fill value' shall be taken as meaning the volume measured in cubic centimetres taken up by 1 gram of product. Fill value is measured using a Borgwaldt Densimeter (DD 60A) by taking a known weight of sample contained in a stainless steel cylinder of known dimensions, for example a cylinder of 3cm radius, and subjecting the sample to pressure from a weighted piston (for example kg extra weight) for 30 seconds. The residual height of the compressed sample is measured and converted to volume. Results are recorded in cm 3 Measurements of fill value were done with the equipment described.
Bulk density shall be taken as meaning the weight of product (grams) per unit volume (cm 3 Results are recorded in g/cm 3 The present invention provides an agglomerated tobacco filler material comprising tobacco dust and binder, the amount of tobacco dust and binder being present at more than 90% by weight of the agglomerated tobacco filler material, said IN D O agglomerated tobacco filler material having a fill value substantially similar to the fill O-i value of cut tobacco, such that the agglomerated tobacco filler material has a reduced 0D 00 tendency to de-blend from cut tobacco than agglomerated filler materials having a fill value substantially dissimilar to the fill value of cut tobacco.
5 Unless the context clearly requires otherwise, throughout the description and the 0 0 claims, the words 'comprise', 'comprising', and the like are to be construed in an CI inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the CI sense of "including, but not limited to".

The agglomerated tobacco filler material of the present invention advantageously has a bulk density substantially similar to that of cut tobacco.
The bulk density value of a product is essentially equal to the reciprocal of the fill value for that product. For the agglomerated tobacco filler material the bulk density should advantageously be matched to that of cut tobacco, such that the agglomerated tobacco filler material will have a reduced tendency to de-blend when compared with products, such as the products described in GB 2201081, having a bulk density substantially dissimilar to that of cut tobacco.

Preferably the humectant is present in the range of 1% to about 5% by weight of the agglomerated material.
The humectant improves the flexibility and the moisture content of the agglomerated tobacco filler material such that the filler material is more robust during handling and storage.
The agglomerated tobacco filler material may additionally comprise inert fillers and/or flavourant material.
Suitably the inert filler may be one or more of the group consisting of silicates or alumino-silicates, such as perlite, vermiculite, diatomaceous earth, talc or colloidal silica; chalk, or metal oxides, metal salts or hydroxides such as magnesium oxide, magnesium sulphate, calcium or magnesium carbonate or alumina, or other inert fillers known to those skilled in the art.
The present invention also provides a smoking article comprising a rod of smokable material wrapped in a wrapper, wherein agglomerated tobacco filler material WO 03/055337 PCT/GB02/05899 of the present invention is blended with cut tobacco and/or reconstituted tobacco.

Advantageously a smoking article incorporating the agglomerated tobacco filler material of the present invention has a firmness value substantially similar to that of a smoking article incorporating a standard Virginia blend having 10% reconstituted tobacco sheet.
The present invention further provides a robust agglomerated tobacco filler material having improved handling properties. This is particularly advantageous in view of degradation suffered in tobacco primary and secondary processing stages. The agglomerated tobacco filler material has a robustness measured in accordance with the method described in Example 3 below. Robustness may be expressed as the loss of agglomerated tobacco filler material during the milling process, i.e. it is a measure of the size reduction of granules as a result of degradation. Loss of agglomerated product is the difference between the percentage of agglomerated tobacco filler material retained on sieves of greater then 710pm before milling and the percentage of agglomerated tobacco filler material retained on sieves of greater then 710pm after milling.
WO 03/055337 PCT/GB02/05899 12 Preferably the loss after milling is less than about by weight of agglomerated tobacco filler material, more preferably the loss after milling is less than about by weight of agglomerated material. The loss after milling is even more preferably less than about 32% by weight and is most preferably less than about 20% by weight of agglomerated tobacco filler material. The robustness of the agglomerated product may depend upon the binder used in the agglomeration process. The effectiveness of the binders in making a robust product may be listed from most effective to least effective as Apple Pectin PVP HPC Alginate Maltodextrin CMC.
Preferably the binder providing the most robust agglomerated tobacco filler material is Apple pectin.
The present invention further provides a method of producing the agglomerated tobacco filler material of the present invention, wherein tobacco dust of particle size not more than 500Am is fluidised in a stream of warm air and binder is applied to said fluidised tobacco dust, such that an agglomerated tobacco filler material is produced having a fill value substantially similar to that of cut tobacco.
Preferably the inlet temperature of the air is not more than 80 0
C.
Suitably the binder is sprayed onto the fluidised tobacco dust at a spray rate in the range of about WO 03/055337 PCT/GB02/05899 13 0.01431/min/kg tobacco dust to about 0.0571/min/kg tobacco dust. Preferably the spray rate is about 0.02861/min/kg tobacco dust.
Suitably the tobacco dust and binder are mixed using the method of the present invention for between 20 and minutes.
Preferably the agglomerated tobacco filler material produced by the method of the present invention has a fill value substantially similar to that of cut tobacco.
In order that the invention may be easily understood and readily carried into effect, reference will now be made to the following examples.
Example 1 Tobacco dust is ground to give a particle size of less than 500Am diameter and a .bulk density of between 0.3g/cm 3 and 0.38g/cm 3 300-350g of tobacco dust is loaded into the product container of an Aeromatic-Fielder STREA-1. The instrument is operated using the top spray nozzle and an inlet air temperature of 60 0 C. The outlet air temperature is in the range of 27 to 39 0 C. The dust is then fluidised in a stream of warm air. The agglomeration fluid, containing the binder, is sprayed onto the fluidised tobacco dust at a spray rate of WO 03/055337 PCT/GB02/05899 14 approximately 10ml/min. for between 20 and 60 minutes.
The resulting agglomerated tobacco product is thus agglomerated and dried in a single operation. The moisture content of the agglomerated tobacco filler material at the end of the agglomeration process is between 12 and 16%, and is ideally about 14%. Before incorporation into a smoking article, the agglomerated tobacco filler material is conditioned to a moisture content of between 11% and 16%.
