Definitions

  • the present invention relates to an improved method for expanding and drying of tobacco, and a plant for implementing the method.
  • tobacco means any treated or non-treated part of the plant (leaf, rib or stalk), shredded or not shredded, provided it is usable in a productive process for smoking products.
  • Tobacco expansion methods are known; they are aimed at reducing the weight of the tobacco with which the smoking products are produced, while at the same time obtaining the desired organoleptic characteristics for the tobacco.
  • these tobacco expansion methods are based on the principle of saturating the tobacco with a fluid, for example water, carbon dioxide or other easily evaporable fluid, then causing it to rapidly evaporate in order to stress the cells which form the leaf tissue (lamina or rib) and cause them to increase in volume.
  • a fluid for example water, carbon dioxide or other easily evaporable fluid
  • the tobacco is fed through a rotary valve into a substantially flat horizontal expansion conduit, and made to advance therethrough by a flow of hot process fluid between 1.5 and 3.5 kg having a velocity between 12 m/sec and 100 m/sec.
  • the process fluid and tobacco are then fed through a tube into a drying tower fed at its base with a rising flow of hot air.
  • Tobacco expansion is known to be caused by the condensation of superheated steam onto the tobacco.
  • the contact time between the steam and the tobacco for causing expansion of this latter is equal to a fraction of a second, with the quantity of steam which condenses onto the tobacco being inversely proportional to the process gas temperature.
  • the water contained in the tobacco cell is made to migrate by diffusion or capillarity towards the outer surface of the tobacco, to be transformed into steam.
  • the migration velocity, and hence the tobacco drying rate depends, for equal conditions, on the temperature difference existing between the tobacco and the process fluid.
  • the drying capacity of the superheated steam is less than that of hot air of the same temperature, until a value is reached known technically as the "inversion point", which varies depending on the material dried.
  • the expansion is reduced and/or even converted into a shrinkage effect.
  • the process fluid temperature has to be increased, however such an increase automatically causes an undesired reduction in the tobacco expansion.
  • the main object of the invention is to propose an improved method which optimizes the tobacco expansion and drying while at the same time results in an energy saving.
  • Another object of the invention is to propose a plant which uses said method while being of simple, quick and low cost construction.
  • the plant 2 comprises a tobacco feed station 4 provided with a rotary valve 6 having the double purpose of feeding the tobacco in volumetrically metered manner while at the same time reducing air ingress into the downstream part of the plant. This prevents the oxygen contained in the air being able to set fire to the tobacco and in any event prevents the air from being able to alter the heat exchange.
  • the feed station 4 suitably receives the shredded tobacco from an upstream soaking plant, not shown.
  • the outlet of the rotary valve 6 opens into a feed channel 8, for example a hopper preferably of vertical extension, provided with a lateral conduit 10 for introducing saturated steam.
  • the conduit 10 is suitably controlled such as to introduce saturated steam into the feed channel 8 in a weight proportion to the tobacco weight of between 0.15 and 0.5.
  • the feed channel 8 flows into an expansion channel 12, preferably of horizontal extension, provided with a first centrifugal fan 14 fed with process fluid originating from an entry conduit 16.
  • the process fluid consists partly of air and preferably of an air and steam mixture.
  • the tobacco which enters the expansion channel 12 is made to advance therealong, urged by the first centrifugal fan 14, which regulates the hourly flow rate and the pressure of the process fluid originating from the conduit 16.
  • the characteristics of the expansion channel 12 could be those described in Italian patent application VE2010A000035 , which for this purpose is to be assumed to be entirely contained herein.
  • the conduit 10 also communicates with the fan 14, via a connection conduit 17, such that the steam introduced into the feed channel 8 through said conduit 10 can be mixed, before contact with the tobacco, with the process fluid originating from the fan 14.
  • the steam introduced via the conduit 10 reduces the oxygen content present in the process fluid such that, for equal conditions, the process fluid which is mixed in the expansion channel 12 requires a smaller steam quantity to achieve the desired tobacco expansion.
  • the process fluid present in the expansion channel 12 has a velocity between 14 m/s and 60 m/s, preferably between 20 m/s and 50 m/s, and a temperature between 110°C and 210°C.
  • the concentration of the air and steam components present in the superheated process fluid are controlled such that the weight quantity of O 2 present in the fluid is between 0.5% and 3% on the total process fluid weight.
  • the expansion channel 12 flows into a dryer 20 fed via a conduit 22 with process fluid originating from a heat generator 24.
  • the conduit 22 leaving the heat generator 24 is arranged to feed into the tower of the dryer 20 a further quantity of heated process fluid such as to modify the weight ratio of tobacco to the heating process fluid.
  • the process fluid fed through the conduit 22 has a temperature between 140°C and 280°C, preferably between 160°C and 250°C, the concentrations of the air and superheated steam components present in the process fluid being controlled such that the weight quantity of O 2 present in the fluid is between 0.5% and 13% on the total process fluid weight.
  • the outlet of the dryer 20 is connected to a tangential separator 26 arranged to separate the tobacco from the heating process fluid.
  • the tangential separator 26 is of suitable shape and dimensions defined on the basis of the tobacco and heating fluid characteristics, and is also provided with a rotary valve 28 for discharging the dried tobacco treated in this manner to the outside of the plant.
  • conduit 30 for the spent process fluid separated from the dried tobacco.
  • This conduit 30 is connected to a second fan 32 which feeds the process fluid into the heat generator 24 through a further conduit 34.
  • a conduit 36 is also connected to the conduit 34 to introduce saturated steam in order to reduce the oxygen content of the process fluid circulating through this conduit.
  • a conduit 38 is also provided to expel a part of the process fluid to the outside of the plant 2.
  • the conduit 30 which leaves the tangential separator 26 is also connected via a recirculation conduit 40 to a third fan 42 which feeds the process fluid, via a further conduit 44, to the conduit 16 which feeds the fan 14 with the process fluid originating from the heat generator 24.
  • the process fluid in the recirculation conduit 40 has a temperature between 120°C and 200°C, the weight quantity of O 2 present in the fluid being between 1% and 13% on the total process fluid weight.
  • connection conduit 46 to the inlet conduit 16 of the fan 14.
  • an inlet 48 is suitably associated for a possible further introduction of saturated steam into said conduit in order to reduce the oxygen content of the process fluid circulating through the conduit 46.
  • the process fluid in the recirculation conduit 46 has a temperature between 140°C and 240°C, the concentrations of the air and superheated steam components present in the process fluid being controlled such that the weight quantity of O 2 present in the fluid itself is between 1% and 3% on the total process fluid weight.
  • Means are also provided at the inlet conduit 16 to the expansion channel for controlling the mixing of the process fluid originating from the recirculation conduit 46 with that originating from the conduit 44.
  • the aforedescribed plant operates in the following manner.
  • the tobacco originating from the feed channel 8 then passes into the expansion channel 12 where it encounters the flow of process fluid urged by the fan 14. This flow causes a second and further expansion of the tobacco.
  • a part of the steam fed through the conduit 10 is, before entering into contact with the tobacco, mixed with the process fluid originating from the fan 14, through the connection conduit 17, such as to reduce the oxygen content of the fluid.
  • the temperature of the process fluid in the expansion channel 12 is regulated by mixing within the inlet conduit 16 the heated process fluid originating directly from the tangential separator 26, with the heated process fluid which emerges from the heat generator 24.
  • the temperature of the process fluid in the expansion channel 12 can be furthered lowered by feeding saturated steam through the inlet 48 and into the recirculation conduit 46 connected to the conduit 22 leaving the heat generator 24.
  • the tobacco After undergoing a first expansion in the feed channel 8 and a second expansion in the expansion channel 12, the tobacco leaves this latter and is introduced into the dryer 20 where it is dried by the further hot process fluid originating from the conduit 22.
  • the temperature of the process fluid in the conduit 22 can be suitably increased such as to increase the drying capacity of the dryer 20, and hence increase the productive capacity of the entire plant.
  • the tobacco is separated from the heating fluid and discharged, via the rotary valve 28, to the outside of the plant 2 or to a subsequent station, while the spent fluid is fed into the conduit 30. From there, the fluid is drawn into the recirculation conduit 40 by the third fan 42, and is fed thereby into the inlet of the conduit 16 and to the fan 14, to be returned into the expansion channel 12.
  • the spent process fluid fed into the conduit 30 from the tangential separator 26 is also drawn in by the second fan 32, and a part is discharged to the outside via the conduit 38, while a further part is fed into the heat generator 24, to be then fed to the dryer 20 through the conduit 22.
  • the said process fluid present in the conduit 22 is also fed, via the recirculation conduit 46, to the conduit 16 and to the fan 14 to be returned to the expansion channel 12.
  • the method and plant according to the invention are particularly advantageous, in that the introduction of saturated steam into the tobacco feed channel 8 enables the tobacco to be subjected to an initial expansion treatment, such that when the tobacco is brought into contact in the expansion channel 12 with the process fluid, which is under the ideal physico-chemical conditions for the properties to be obtained, it undergoes a second thermal stress with consequent further expansion.
  • the tobacco undergoes two consecutive expansion treatments, one within the feed channel 8 and one within the expansion channel 12, the final expansion achieved thereby taking account of the plastic deformation undergone in both treatments, in accordance with that envisaged by Hooke's law and by the relative elastic modulus of the material.
  • the fact of using in the plant expansion channel 12 a process gas temperature less than that of the feed channel 8 enables the best expansion and drying conditions to be defined, and hence the tobacco organoleptic characteristics to be optimized.
  • the introduction of steam into the feed channel 8 enables the steam quantity fed into the conduit 36 to be reduced. Consequently for equal tobacco expansion, the overall plant yield is improved.
  • the method and plant according to the invention also result in a considerable energy saving as the flow of process fluid used in the expansion channel 12 is obtained by suitably mixing the fluid recovered from the outlet conduit 30 from the tangential separator 26, with that recovered from the outlet conduit 22 of the heat generator 24.
  • the quantity of process fluid introduced into the expansion channel 12 can be controlled simply by varying the r.p.m. of the fan 14.
  • the method and plant are more advantageous than the traditional ones, in that for equal energy consumption they enable the tobacco expansion to be optimized, while enabling a greater tobacco quantity to be dried. Moreover, this optimization of the expansion and drying step is achieved by using a single heat generator 24; in particular, the presence of two separate heat generators in order to independently control the temperature of these two steps is not required.
