Definitions
- the invention relates to a method for producing cut tobacco.
- Tobacco is dried in the growing countries after harvest, fermented and then packed. The dried tobacco leaves are pressed into bales and shipped for further processing of the tobacco.
- these tobacco bales are processed and conditioned. At the end of this process is Thomastabak, as it is provided, for example, the strand forming for the production of cigarettes.
- the cigarette should have a desired mechanical stability, while a head loss should be prevented.
- a high filling power in a cigarette can be achieved by, for example, expanding the rib portion or leaf portion.
- the object is achieved by a method for producing cut tobacco with the following steps:
- the harvested tobacco leaves are dried, pressed, packaged and then threshed.
- the term "green leaf” refers to a tobacco material, ie tobacco leaves, which is neither dried nor pressed or packed The green leaf is fermented and threshed but not pressed or dried.
- the green leaf has a higher relative humidity, which is about 19% Dried tobacco leaves from conventional processes usually have a relative humidity of about 12.5%. on.
- step a) takes place in Brazil, so the tobacco leaves are harvested in Brazil.
- cut tobacco having a high filling force can be produced.
- this cut tobacco has no or virtually no adverse effects on the manufacture and processing of the cigarettes and, above all, does not adversely affect the taste.
- the process without great technical effort, such. B. an additional expansion plant, feasible. It is therefore extremely efficient and economical because process steps are saved.
- the fermented tobacco leaves have a relative humidity of about 1 9% and in step d) the relative humidity of the threshed tobacco material to a value between 24% and 28%, in particular to a value between 25% and 27%, and in particular to a value of at least approximately 26%.
- the moisture of the fermented tobacco leaves is adjusted so that water absorption and cell penetration can best take place.
- the cells of the leaves are changed so that their structure changes from an elastic structure to a plastic structure.
- the method is further developed in that between step d) and e) in an additional step d 1) the moistened, threshed tobacco material, in particular with steam, is heated until the tobacco material has a temperature between 35 ° C and 40 ° C Has.
- Heating increases the consistency of the threshed tobacco mate- changed. It can be adjusted so that in the subsequent step of cutting a homogeneous cutting quality can be achieved.
- step e) the tobacco material is cut into cut tobacco with a width of between 1.3 mm and 1.7 mm, in particular with a width of between 1.4 mm and 1.6 mm.
- the mentioned cutting widths are larger than with conventional cut tobacco. In this way, an optimal volume can be achieved.
- the desired particle size is set, which can be tolerated maximally in the size distribution used for the production of the cigarette or for strand formation.
- step e) in an additional step e1) the cut and moistened tobacco material, in particular with steam, is heated to a temperature between 85 ° C and 95 ° C.
- a moistening is achieved.
- the cut tobacco material curls at the said temperature between 85 ° C and 95 ° C, so that a high filling force is achieved.
- the temperatures indicated are the temperature of the tobacco material itself.
- step f) the drying of the tobacco material takes place with hot air, which in particular has a temperature between 120 ° C and 150 ° C. Drying takes place, for example, in a drying drum, in other words in a drum process.
- the tobacco material undergoes a temperature shock, so that the existing water escapes at high speed from the tobacco material. This increases the plasticity of the cell structures.
- the method is further developed in that, after step f), the cut tobacco is cooled in an additional step g), the cooled tobacco material in particular having a moisture content of 11% by weight.
- This additional cooling causes the tobacco material to solidify in its shape.
- the air used for cooling is adjusted to provide optimum heat transfer, thus "freezing" the plasticity previously achieved.
- step c) in an additional step c1) a casing is applied to the threshed tobacco material and / or after step f) in a further step gl) at least one flavor is applied to the cut tobacco.
- a casing is applied primarily for the purpose of improving the resistance of the tobacco material to pressure, drying and cooling.
- a flavor introduced at the end of the process serves to specifically refine the taste of the cut tobacco.
- the cut tobacco is packed.
- the cut tobacco is packed in particular airtight, for example, in film in order to obtain the optimum humidity achieved.
- step a tobacco leaves of tobacco plants are harvested. This step takes place, for example, in Brazil.
- Brazilian tobaccos have proven to be particularly suitable for the process according to the invention.
- step b the harvested tobacco leaves are fermented.
- step c) the green fermented tobacco leaves are threshed and processed into threshed tobacco material.
- the tobacco leaves are not dried after threshing and also not packed or pressed.
- the green tobacco leaves have, in contrast to other methods, a higher moisture content of about 19%.
- threshed tobacco leaves have a moisture content of about 12.5%.
- step d) the threshed tobacco material is moistened.
- the tobacco material is brought to a humidity of, for example, 26%.
- step d 1) a casing order is made to make the tobacco material more resistant to the further process.
- step e) the wetted tobacco materials are cut and so processed to cut tobacco.
- step d 1) it is provided that before the tobacco materials are cut, they are heated.
- the tobacco material is heated by means of steam to a temperature between 35 ° C and 40 ° C.
- a serrated knife is used for the cutting in step e). These knives are commonly referred to as “castellated knives.”
- the selected cutting width which is between 1, 4 mm and 1, 6 mm, for example, between 1, 3 mm and 1, 7 mm, in particular at 1, 5 mm, is greater than the cutting width used in conventional methods.
- step e1) the cut and moistened tobacco material, in particular with steam, is heated to a temperature between 85 ° C and 95 ° C. This causes the tobacco material to curl, so that a high filling force can be achieved.
- the temperature indicated is the temperature of the tobacco material.
- step f) the tobacco material is dried.
- hot air is used, which has a temperature between 120 ° C and 150 ° C.
- step g) the tobacco material is cooled so that it solidifies in the desired shape.
- a belt or drum cooler is used. The cooled tobacco material then has a moisture content of about 1 1 wt.%.
- a flavor additive can be applied to the cut tobacco.
- the tobacco material is packaged in the optional step h) so that it retains its optimum moisture.
- the tobacco material is packaged in foil.
- the presented method of producing cut tobacco is much more efficient than conventional methods.
- the drive no or very little negative impact on the taste of the tobacco material.
- Another advantage is that the method with manageable technical effort is feasible. For this reason, the process is very economical. In the result cut tobacco can be provided, which has a high filling power and taste brings no disadvantages.
