Definitions
- the subject invention relates to smokable filler materials and more particularly to agglomerated tobacco filler material, and smoking articles incorporating such material.
- 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.
- Such reconstituted products have fill values in the range of 2.5cm 3 /g to 3.5cm 3 /g, these fill values being substantially lower than those of cut tobacco (5cm 3 /g to 6cm 3 /g) and reconstituted tobacco sheet (8.0cm 3 /g to 8.5cm 3 /g).
- WO 01/74968 describes a method of producing smoking articles of reconstituted tobacco comprising 80% tobacco dust and 5% binder.
- the product produced by the method has a fill value of 3.8-5.0cc/g.
- the smoking article is a substantially cylindrical, foamed, extruded article comprising 5-98% tobacco particles and 2-40% of a cellulosic binder, with a density of 0.05 to 1.5g/cc.
- GB 2201081 discloses a reconstituted tobacco product comprising particulate tobacco and a binder up to 10% by weight.
- US 4611608 discloses a tobacco mixture for smoking articles comprising 10% tobacco dust, about 69% cut tobacco and 10% maltodextrin.
- 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.
- the present invention also has as an object an agglomerated tobacco filler material that is produced using fluidised bed technology and low process temperatures in a one-step procedure.
- '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 1kg extra weight) for 30 seconds. The residual height of the compressed sample is measured and converted to volume. Results are recorded in cm 3 /g. 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 in accordance with claim 1.
- the tobacco dust and binder are present at more than 90% by weight of the agglomerated tobacco filler material.
- the agglomerated tobacco filler material has a fill value in the range of 4.40cm 3 /g to 5.50cm 3 /g, and more preferably is in the range of about 4.90cm 3 /g to about 5.30cm 3 /g.
- the agglomerated tobacco filler material has a granule size up to 3.5mm. More preferably the granule size is at least 0.7mm and not more than about 2.0mm. Most preferably the granule size is in the range of about 0.8mm to about 2.0mm.
- the agglomerated tobacco filler material has a moisture content in the range of 8% to 18%. More preferably the agglomerated tobacco filler material has a moisture content in the range of about 10% to about 15.5%.
- 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.
- 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.

Abstract
Description
- The subject invention relates to smokable filler materials and more particularly to agglomerated tobacco filler material, and smoking articles incorporating such material.
- 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.
- 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 2.5cm3/g to 3.5cm3/g, these fill values being substantially lower than those of cut tobacco (5cm3/g to 6cm3/g) and reconstituted tobacco sheet (8.0cm3/g to 8.5cm3/g).
- 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.
- WO 01/74968 describes a method of producing smoking articles of reconstituted tobacco comprising 80% tobacco dust and 5% binder. The product produced by the method has a fill value of 3.8-5.0cc/g.
- In US 4,625,737 a foamed, extruded, tobacco-containing smoking article is described. The smoking article is a substantially cylindrical, foamed, extruded article comprising 5-98% tobacco particles and 2-40% of a cellulosic binder, with a density of 0.05 to 1.5g/cc.
- GB 2201081 discloses a reconstituted tobacco product comprising particulate tobacco and a binder up to 10% by weight.
- US 4611608 discloses a tobacco mixture for smoking articles comprising 10% tobacco dust, about 69% cut tobacco and 10% maltodextrin.
- 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 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 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.
- It is an even further object of the present invention to provide an agglomerated tobacco product capable of being used instead of, or in 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 tobacco.
- It is a yet further object of the present invention to provide an agglomerated tobacco filler material having acceptable handling properties and reduced frangibility such that the product may be directly incorporated into smoking articles without the need for further processing.
- The present invention also has as an object 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 1kg extra weight) for 30 seconds. The residual height of the compressed sample is measured and converted to volume. Results are recorded in cm3/g. Measurements of fill value were done with the equipment described.

- 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.

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 710µm before milling and the percentage of agglomerated tobacco filler material retained on sieves of greater then 710µm after milling.

- 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.
- Tobacco dust is ground to give a particle size of less than 500µm diameter and a bulk density of between 0.3g/cm3 and 0.38g/cm3. 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°C. The outlet air temperature is in the range of 27 to 39°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 approximately 10ml/min. for between 20 and 60 minutes. The resulting agglomerated tobacco product is thus agglomerated and dried in a single operation.

- It is interesting to note that as the fill value of the agglomerate is less than that of the tobacco blend, the density of a smoking article incorporating the agglomerated tobacco filler material would be expected to be higher than that of a smoking article not containing the agglomerated material. Instead the physical measurements show that the density of smoking articles incorporating the agglomerated product are lower than smoking articles not containing the agglomerated material.
