Definitions
- the present invention relates to a method and a plant for producing reconstituted tobacco, both of the conventional type and of the non- conventional type, the latter also referred to as H N B (Heat Not Burn).
- the reconstituted tobacco is obtained by using tobacco by- products and processing waste (ribs, small pieces of leaves, dust, etc.) which, properly shredded until they are practically reduced to powder and mixed with water, glycerine binders and other liquid additives, allow to obtain an extremely fluid mixture (slurry) having a liquid content of about 70% by weight, which is then poured into a veil on a steel belt and with this transferred into a drying oven.
- slurry extremely fluid mixture
- the evaporation of the liquid fraction of the mixture takes place, so that the solid residue forms a sort of continuous tobacco strip having approximately the same width as the steel belt.
- the strip of dried mixture is separated from the steel belt and is cut into pieces of various sizes depending on the request. These pieces are then transformed into thin filaments which, suitably mixed, are fed to a conventional packaging machine for cigarettes.
- the reconstituted tobacco is distinguished as conventional or unconventional.
- WO 2016/050469, WO 2016/050470, WO 2016/050471 , WO 2016/050472 describe known techniques of production of reconstituted tobacco, which require plants of considerable size and involve high energy consumption to bring the mixture, which when it is produced is rather fluid, to the consistency of a tobacco sheet. It is sufficient to point out that a drying oven can reach 100 m in length.
- Another drawback of the known techniques of production of reconstituted tobacco with the use of the by-products consists in the fact that the formation of the sheet starting from the layer of mixture is rather irregular, since the starting products are not homogeneous and their distribution on the steel belt is not uniform; it follows that the reconstituted tobacco sheet does not allow it to be reeled, nor to be cut regularly.
- the object of the invention is to eliminate these drawbacks and to produce reconstituted tobacco of both conventional and unconventional types, with implants of much smaller dimensions.
- Another object of the invention is to produce reconstituted tobacco with limited energy consumption.
- Another object of the invention is to produce reconstituted tobacco using equipment partly already available on the market, even if never used in this specific technical field.
- Another object of the invention is to produce reconstituted tobacco which is alternative to traditional methods.
- Another object of the invention is to produce reconstituted tobacco with characteristics suitable for satisfying different market demands.
- Another object of the invention is to produce reconstituted tobacco operating at low temperature and thus preserving all the aromas of tobacco.
- the method according to the invention for producing reconstituted tobacco is characterized in that it comprises the carrying out, in sequence, of the following steps:
- the solid components of tobacco are comminuted until they reach a granulometry of about 20 - 220 pm, preferably about 80-180 pm, - the comminuted product thus obtained is mixed with water, at least one binding agent and at least one material to form an aerosol until a mixture with a liquid content of about 30-50%, preferably about 35-40%, is obtained,
- said mixture is subjected to a first lamination to obtain a continuous strip having a thickness of about 1 -20 mm, preferably of about 1 -10 mm,
- Figure 1 shows in a schematic general view a plant for the production of reconstituted tobacco according to the invention
- Figure 2 shows its power supply section in the case that the plant is intended for the production of reconstituted tobacco of the conventional type
- Figure 3 shows its power supply section in the case the plant is intended for the production of reconstituted tobacco of the unconventional (H N B) type
- Figure 4 shows its feeding section of the ribs
- Figure 5 shows its milling mixing and storage sections
- Figure 6 shows in a schematic view its refiner displacements
- Figure 7 shows a plane view of its layering section in a different embodiment
- Figure 8 shows in a schematic view its hot air drier
- Figure 9 shows in a schematic view its hot air drier in a different embodiment.
- the plant for producing reconstituted tobacco according to the invention comprises several sections arranged in series and aimed at operating on the input raw materials until they are transformed into a continuous strip of reconstituted tobacco to be sent for subsequent packaging operations of the cigarettes.
- the plant according to the invention for the production of reconstituted tobacco comprises:
- said comminution unit comprises a mill 20 (preferably cryogenic) and/or a grinder 24 and/or a hammer mill 54;
- a kneading machine 80 which is fed with metered quantities of comminuted material, with water, with at least one binding agent and with at least one material to form an aerosol; said kneading machine being configured to obtain a mixture with a liquid content of about 30-50%, preferably about 35- 40%,
- a first lamination unit 100 for obtaining from said mixture a continuous strip having a thickness of about 1 -20 mm, preferably of about 1 -10 mm,
- a rolling line 1 16 located downstream of said first lamination unit 100 to carry said continuous strip to a thickness of about 90-280 pm, preferably about 140-200 pm,
- a drier 122 placed downstream of said rolling line 1 16, to bring the liquid content of said strip, laminated and coming out from said rolling line 1 16, to about 8-15%.
- the plant 1 also comprises a mixture forming unit 92 for forming a plurality of portions 97 of said mixture; suitably, therefore, the first lamination unit 100 is configured to obtain, from the portions 97 of said mixture, a continuous strip having a thickness of about 1 -20 mm, preferably of about 1 - 10 mm.
- the plant according to the invention comprises: - a pre-treatment section of the starting solid products (tobacco leaves, ribs, fragments of leaves, powder, etc.) for the preparation thereof to subsequent grinding treatments,
- the starting solid products tobacco leaves, ribs, fragments of leaves, powder, etc.
- said milling section comprises said comminution unit
- the section for preparing and pre-treating the starting solid products is different depending on whether the implant is intended to produce reconstituted conventional tobacco (fig. 2) or non- conventional type (fig. 3).
- it may be provided also a section of preparation and pre-treatment of the tobacco ribs (fig. 4), to be used for the production of reconstituted tobacco both conventional type that unconventional type.
- the preparation and pre-treatment section in the case in which the preparation and pre-treatment section is intended to supply a plant for the production of reconstituted tobacco of the conventional type (fig. 2), it includes a tilter 2 of cartons containing tobacco products, to overturn their contents on a feeder 4 of a vibrating conveyor 6, which separates any heavy bodies from the product to be treated.
- the heavy bodies are collected in a suitable container 8, while the product to be treated is transferred, through a pneumatic conveyor line 10, to a cyclone 12, a conveyor belt 14, provided with metal detector 16 for the removal of any metal bodies, and a pneumatic conveying line or 18, to a mill 20, advantageously of the cryogenic type.
- the preparation and pre-treatment section is provided for the preparation of reconstituted tobacco of an unconventional type (fig. 3), it comprises a feeding station with a counter 22 for unloading the bales of tobacco leaves from cartons of approximately 200 kg, which typically contain them, and the transfer of these to a grinder 24.
- the output of this grinder 24 is connected, through a pneumatic conveying line 26, to a cyclone 28, in which the transport air is separated from the solid product, which is transferred to a vibrating sieve 30 for the separation of the fine parts from the remaining parts of the product.
- the output of the fine parts is directly connected with the cryogenic mill 20, while the output of the remaining parts of the product feeds a conventional twine remove machine 32, which provides for eliminating any twine previously not removed from the bales of tobacco leaves.
- the exit of the twine remove machine 32 feeds a separation chamber 34 for the separation of any heavy foreign bodies from the ground tobacco leaves, which through a pneumatic conveyor line 36, a cyclone 38, a strip conveyor 40, provided with metal detectors 42 for removing any metal bodies, and a pneumatic conveyor line 44, are transferred to the cryogenic mill 20.
- the preparation and pre - treatment section for the preparation of the tobacco ribs to be used for the production of reconstituted tobacco of both the conventional and the non-conventional type (Fig. 4), it comprises a tipper 46 for cartons containing the ribs of tobacco, feeder 48 for the ribs to a vibrating conveyor 50, for the separation from these of any heavy bodies, and a pneumatic transport line 52 for their movement to a hammer mill 54, where they are comminuted.
- the hammer mill 54 has its output connected, via a pneumatic conveyor line 56 provided with cyclone filters 58, to one or more storage silos 60.
- the output of the of the storage silo or silos 60 is in turn connected, by means of a screw conveyor 62, to a metering device 64, which provides for dosing the shredded ribs before sending them to the mill 20, preferably cryogenic, through a pneumatic line of transport 66.
- the plant according to the invention also includes the mill 20 (Fig. 5), which carries out the grinding of various products received to bring them to an average particle size of about 20 - 220 pm, preferably about 80-180 pm.
- cryogenic rungs mill which allows the product to be kept at low process temperatures and therefore to retain tobacco aromas.
- the pinned-disk mill is in itself conventional and includes a closed structure with inside a fixed and a rotating disc or two counter-rotating discs, provided with rungs facing and partially interpenetrating each other. Being an apparatus in itself traditional, it has been globally indicated with 20 in fig. 5 but is not shown in its internal construction characteristics or in its operating modes Preferably, the rungs mill 20 is predisposed to make a cryogenic grinding, namely a grinding in the presence of liquid nitrogen.
- a cryogenic pin mill is somewhat more advantageous than a traditional mill, essentially due to the different ways in which the products to be ground are treated. In fact, grinding at room temperature can lead to obtaining products of poor quality, while grinding in the presence of liquid nitrogen preserves the physical properties and the chemical and organoleptic characteristics of the products.
- the amount of liquid nitrogen used in cryogenic grinding processes is a fundamental part to consider when the pros and cons of the process are studied and may vary depending on the materials processed.
- the liquid nitrogen at a temperature of -175°C is injected onto the product inside the chamber of a screw conveyor 68 which feeds the mill 20 and its residence time in contact with nitrogen is about 2 to 5 sec., which is also the transit time of the product inside the cochlea that feeds the pin mill.
- the temperature of the product coming out of the mill 20 is advantageously less than 10°C, in a way that the nitrogen vapours, which are released almost instantaneously upon contact with the tobacco to be cooled, travel upstream all of mill feed system, performing the desired pre-cooling effect.
- the flow of liquid nitrogen in the precooling system and the mill is controlled by thermocouples, that make the cryogenically grinding process fully automatic.
- cryogenic grinding the positive factors of cryogenic grinding are:

- the sieve with a fluidized bed therefore has the function of sorting the product and put back into the cycle in the mill 20 the one with fractions greater than 120 pm, after having them separated from those comprised between 20 pm and 120 pm, that through a line of pneumatic conveying 72 are sent to one or more mixing and storage silos 74.
- the output of the of mixing and storage silos 74 feeds, via a pneumatic transport line 76, and a cyclone filter 78, which has the function of breaking down the dusty air and more specifically to separate the dust, which then is recovered and fed back into the cycle, from the air, which can then be ejected.
- the output of the cyclone filter 78 feeds, through a continuous dosing system, preferably with a screw, the kneader 80, which can be of various types, for example of a horizontal type with overturning or a vertical spiral type.
- the kneading machine 80 is fed with a quantity of minced tobacco, water, at least one binding agent and at least one material to form an aerosol and is configured to obtain a mixture with a liquid content of about 30-50%, preferably by about 35-40%.
- the values of liquid or humidity are intended to be determined according to the measurement system on a wet basis.
- the humidity values are defined as the percentage of water contained in the total mass of the corresponding product and, in other words, it is the percentage ratio between the quantity of water and the total mass of the mixture.
- these values are obtained using the traditional methods provided in the literature for measuring the quantity of water in a product, such as those presented in“Tobacco Moisture, Water and Oven Volatiles - A status report of common moisture methods used within the tobacco industry” By Nils Rose ET AL. in “Analytical and bioanalytical chemistry” (1 July 2014, pages 1 -16).

- a stratification unit 1 10 is configured to lay out the continuous single-layer strip, having a thickness of about 1 -10 mm, which comes out of the first lamination unit 100, on several layers, so as to transform it into a multilayer strip having a thickness of about 2-20 mm., which is then sent to the rolling line 1 16.
- said stratification unit 1 10 consists of an upstream conveyor belt 1 12, which has the function of depositing on a lower downstream conveyor belt 1 14, preferably belonging to the rolling line 1 16, the product strip arranging it so that it is stratified on said downstream conveyor belt 1 14, for example folding it several times on itself.
- the upstream conveyor belt 1 12 is raised above the downstream conveyor belt 1 14 and is provided with a continuous advancement movement with respect to its supporting structure, and at the same time with a reciprocating motion with its supporting structure, parallel to the its longitudinal axis.

- the upstream conveyor belt 1 12 is disposed parallel to the downstream conveyor belt 1 14 provided it the rolling line 1 16 (fig. 1 )
- the upstream conveyor belt 1 12 is arranged orthogonally to the downstream conveyor belt 1 14 provided of the rolling line 1 16 (fig. 8), so that with its movements can distribute the product strip on the whole useful width of the rolling line 1 16.
- the reciprocating movement of the structure supporting the upstream conveyor belt 1 12 stratification unit 1 10 causes a stratification of the strip of product, which exits from the first lamination unit 100 on the underlying first downstream conveyor belt 1 14 of the rolling line 1 16 and the formation of a stratified strip of width substantially equal to the useful width of the rolling line itself.
- the rolling line 1 16 is formed by several lamination stations, each comprising a pair of cylinders 118, which delimit between them an increasingly narrow passage to gradually reduce the strip thickness of the product being processed.
- the rolling line 116 is configured to progressively bring the endless strip to a thickness of 90-280 pm, preferably about 140-200 pm.
- a downstream conveyor belt 114 having a length of preferably about 1.5-2 m, which has the function to rest the product before it is subjected to the next step of lamination.
- the rolling line 1 16 is then completed with one or more calibration stations, each formed by a pair of calibrating cylinders 120.
- the laminating cylinders 1 18 and possibly also the calibrating cylinders 120 can be heated, so as to be able to start the drying step already during the rolling.
- the dryer 122 can be divided into two units 124, 126, placed in series with respect to each other. More particularly, the upstream unit 124 is provided to perform the first drying step and it presents in its interior a carrier made steel sheet or of a mesh conveyor belt for the transport of the product that comes out of the rolling line 16; the downstream unit 126 is provided to perform the second drying step and the subsequent cooling step and is provided inside with a mesh conveyor belt.
- the dryer 122 is advantageously provided at the entrance and exit of sensors 128, preferably with infrared rays, which control the product along its entire length.
- the containers of tobacco scraps are placed on the tipper 2, which reverses the products on the feeder 4, which transfers them to the vibrating conveyor 6.
- Flere takes place the separation of heavy bodies from the tobacco by-products: the former are collected in the container 8 while the latter are transferred by an air flux along the pneumatic conveying line 10 up to the cyclone 12, which separates the air from solid products and let these fall on the conveyor 14, for their transfer, through the pneumatic line 18, to the cryogenic mill 20.
- the cartons containing the tobacco leaves are placed in the unpacking bench 22, where the individual bales of tobacco leaves are removed from the cartons and sent to the grinder 24, which reduces the leaves themselves to a substantially uniform size of between 5 and 10 mm.
- the thus comminuted product is then transferred along the pneumatic conveying line 26 to the cyclone 28, which separates it from the air and makes it fall on the vibrating sieve 30.
- cryogenic mill 20 can also be transferred, if the recipe requires it, the shredded tobacco ribs, which can be used for the production of reconstituted tobacco of both conventional and non-conventional type.
- the shredded ribs, separated in the cyclones 58 by the conveying air, are transferred to the storage silos 60, from which the different types of ribs, coming from different qualities of tobacco, can be withdrawn and transferred through the screw conveyor 62 to the doser of the ribs 64, which doses them according to the particular recipe to be prepared.
- the ribs, shredded and dosed in the correct quantities, are transferred via the pneumatic line transport 66 to the cryogenic mill 20.
- a ground product with an average particle size of approximately 20 - 220 pm, preferably about 80-180 pm.
- the ground product which comes out of the sieve with a fluid bed fed by the cryogenic mill 20, has an average particle size of about 20 - 220 pm, preferably about 80-180 pm.
- the product thus ground is sent to the mixing and storage silos 60, from which the products can then be taken according to requirements and transferred to the kneading machine 80.
- the mixer 80 in addition to the ground tobacco (and preferably the solid products from blending silos and storage 60), also water, at least one binding agent and at least one material to form an aerosol are introduced. Preferably, compressed air and other additives are also added.
- the whole is then mixed together to form a mixture having a percentage of liquids (humidity) of about 30-50%, preferably of about 35-40%, by weight on a wet basis, i.e. a rather dense consistency.
- a percentage of liquids (humidity) of about 30-50%, preferably of about 35-40%, by weight on a wet basis, i.e. a rather dense consistency.
- the mixture thus obtained is transferred to the forming unit 92, from which a plurality of portions 97 emerge, preferably shaped like loaves.
- the portions 97 of mixture, which emerge from the forming unit 92 are transferred at the first lamination unit 100 which is configured to output a continuous ribbon thickness of about 1 -20 mm, preferably about 1 -10 mm.
- This continuous strip which comes from the first lamination unit 100, is directly transferred to the rolling line 1 16 or - by means of the stratification unit 1 10 - is folded onto itself so as to be deposited in stratified form on the input strip 1 14 of the rolling line 1 16.
- the stratification is obtained by dropping the continuous strip on the conveyor belt 1 12, which is made to advance with respect to its support structure, which moves of reciprocating motion, so as to have more than one layer of the product strip on said downstream conveyor belt 1 14.
- the product strip can be arranged on several layers parallel to the longitudinal direction of the rolling line 1 16 or orthogonally to it.
- the strip of product undergoes a reduction in thickness, up to reach, in correspondence with the displaced output calibrating cylinders 120, the desired thickness, which has a value substantially constant of about 90-280 pm, preferably of about 140-200 pm.
- the strip has a liquid content lower to 20% or even 15%, in case the displaced cylinders 1 18 are heated and the water is removed already during the rolling process.
- the product strip coming out of the rolling line 1 16 is then subjected to drying in the dryer 122, where its liquid content is brought to about 8-15%.
- the dryer 122 is in air recirculation, which compared to the driers traditionally used in production systems of reconstituted tobacco is more advantageous in terms of complexity both in terms of encumbrance and in terms of energy consumption.
- the traditional systems treat a product (mixture) very fluid and little stable, unlike the treated product from the plant according to the invention, which is much denser and much more stable. Consequently, while the systems which treat slurries require traditional irradiation and conduction dryers, the plant according to the invention can advantageously use an air recirculating dryer 122 with a net conveyor or a combined system of steel belt conveyors for the first drying step and mesh strip conveyors for the second drying step and the cooling step.
- the product is ready to be wound in a reel or to be shredded into strands of the prescribed size, to be used for the packaging of cigarettes.
- the plant in case the plant is provided for the production of reconstituted tobacco of the unconventional type, in addition to using the different preparation and treatment section already described, it uses, as an alternative to the forming unit 92 or in addition and upstream of this, a refiner to cylinder refiner 130 which has the task of bringing the solid components of the mixture to a particle size of not more than 20 pm.
- the refiner (fig. 6) comprises within a closed container a plurality of cylinders 132 arranged in sequence in narrow closeness between them, so as to delimit the corresponding milling gaps.
- the lower cylinder 132 is mounted with the axis outside the plane containing the axis of all the other cylinders 132 and functions as a feeder of the mixture which is taken from the bottom of the container and made re rise upwards so as to pass between the lower cylinder and the one immediately above and then to follow among all the others.
- the various pairs of cylinders 132 between which the mixture passes rotate at different speeds, in the sense that the upper cylinder rotates at a speed greater than the lower cylinder, with which it cooperates, in order to subject the mixture to a stretch during the passing between the cylinders 132 of each pair and thereby reducing the particle size of the mixture itself.
- One of the fundamental parameters for the success of the refining process is precisely the different speeds of the different cylinders 132, from which depends the passage of the entire mass of the mixture which has passed through the milling gap.
- the pressure between the cylinders is hydraulically controlled.
- All cylinders 132 are cooled with cold water that circulates inside each cylinder and thereby counteracts the heat which is developed from mixing due to friction due to both the movement of the cylinders itself and the rubbing with the product. In this way the temperature of the product is reduced to 25°C.
- the action of friction which is exerted on the mixture by the cylinders 132 of the former, develops a considerable binding action of the cellulose fibres contained in tobacco and in particular in its ribs, and this generates the double advantage of developing the aromatic components of the product and eliminating the need to introduce other fiber into the mixture to obtain the required bonding effect.
- the operation of the plant in this different embodiment requires that the shredded leaves and chopped ribs coming from the preparation and pre- treatment stations are fed to a rungs cryogenic mill 20 in an amount proportionally metered according to the recipe to obtain, and from this are brought to a particle size of about 20 - 220 pm, preferably about 80-180 pm.
- the product is then transferred in the manner already described in the mixer 80, in which a product mixture is formed as described above.
- the mixture thus obtained is then fed to the cylinder refiner 130, which has the task of bringing the solid components of the mixture to a particle size not exceeding 20 pm.
- the action of friction exerted on the mixture by the cylinders 132 of the cylinder refiner 130 develops a considerable binding action of the cellulose fibers contained in the tobacco and in particular in its ribs, and this causes the dual advantage of developing, on one hand, the aromatic components of the product and, on the other hand, eliminating the need to introduce other fibers into the mixture to obtain the required bonding effect.
- FIG. 1 schematically indicates the position of the cylinder refiner 130 between the kneading machine 80 and the forming unit 92, but the invention also provides that the cylinder refiner 130 can be an alternative to the forming unit 92, and in this case the mixture which exits from the cylinder refiner 130 is transferred directly to the first lamination unit 100, for the continuation of the processing cycle according to the methods already described.
