Definitions

  • the invention relates to a method for producing a smokable tobacco product.
  • DE-33 39 247 C1 discloses a process for producing crimped fiber pieces from reprocessed tobacco, in which tobacco dust and / or tobacco waste are processed with binders and, if appropriate, additives to form a plastifiable mixture.
  • a cylindrical strand of the plasticized mixture is formed into a thin-walled, continuously expanding hollow body and divided into thread-like, crimping intermediate products, which are then separated into individual, crimped fiber pieces.
  • DE-38 19 534 Cl discloses a method for producing tobacco foil pieces from reprocessed tobacco. Dust-like tobacco waste and / or tobacco flour is mixed with binders and possibly additives and the mixture thus obtained is plastified in an extruder. The plasticized mixture is divided into an even number of mechanically / geometrically identical cylindrical strands via flow paths of exactly the same length. Two adjacent, identical ones
  • Strands are rolled together to form a film strip, which is then cut into pieces of film.
  • the mixture is plasticized in the extruder at temperatures of 90 to 120 ° C and pressures of 50 to 100 bar.
  • the cylindrical strands have a diameter of 2 to 7 mm.
  • DE-40 05 656 AI describes a process for producing a tobacco-containing film with increased filling power.
  • the moist raw mass is then extruded in an extruder with a temperature profile of approx. 30 ° C. to approx. 160 ° C. at a pressure of approx. 10 to approx. 200 bar and pressed through a nozzle provided with an exit gap, whereby the tobacco Foil is created.
  • This tobacco film is then strongly heated from both sides, as a result of which largely gas-impermeable cover layers form on the tobacco film. Due to a further strong supply of heat, the water in the tobacco foil is evaporated between the cover layers, whereby bubble-shaped cavities are created.
  • the object of the invention is to develop a novel smokable tobacco product or a method for its production.
  • the plasticized mixed mass which is porous through the through-flow channels, is expanded or foamed by a drop in temperature and pressure, solidified as a continuous, porous, cylindrical strand and cut to length in the desired lengths.
  • the channels created by introducing water vapor into the mixed mass remain in the extruded strand in the form of longitudinal and radial channels.
  • the strand produced according to the invention is also air-permeable in such a way that the combustion air is sucked evenly through the strand cross-section and the strand length when being smoked, the tensile resistance given by the strand not exceeding an upper value.
  • Native and / or modified starch can be used as the binder, the proportion of the binder advantageously being about 15% by weight.
  • humectants can be added, such as. B. glycerin, molasses and / or other hygroscopic substances.
  • fire improvers can be provided as additives, for. B. organic acids to produce a white fire of the ashes and / or carbonates or wetting agents to improve the smoldering ability.
  • flavors and / or flavorings can also be provided as additives, such as. B. aroma precursors, extracts and steam distillates from ripened leaves of plants other than tobacco plants.
  • Biological film-forming additives are also advantageous additives.
  • PVA polyvinyl alcohol
  • PVAC polyvinyl acetate
  • additives from gene-assisted production can also be used.
  • a water vapor pressure of 50-120 bar, preferably approximately 80 bar, is selected to generate the channels required for smoking.
  • the tobacco particles used for the mix can be produced by crushing mature tobacco leaves, but can also be waste from conventional tobacco processing. Tobacco particles are preferably used in a sieve size of about 3 to 5 mm.
  • the mature tobacco which is packaged in a commercially available manner, has undergone a lengthy biochemical development: Even before the leaves are harvested, tobacco degradation occurs in the field, which continues after harvesting with increasing yellowing, drying and fermentation.
  • the ripening chemistry is essentially dependent on the slowest possible water loss.
  • the starch and protein concentrations which were initially relatively high in the vital state, are hydrolyzed with still high water content up to about 80% by weight and converted into soluble sugars and nitrogen compounds. If the water content is ⁇ 80%, the enzymes that trigger these processes become inactive; the so-called leaf death occurs.
  • the strand sections produced according to the invention are conditioned in a ventilated, climate-controlled environment, that is to say they are kept in air-permeable containers in climate-controlled chambers.
  • the conditioning takes place up to a final moisture content in the strand of about 10 to 13% at about 50 ° C.
  • the transfer to the last production stage then takes place in this state:
  • the so-called "aging” consists of storing the strand sections over a period of about 0.5 to 2 years at 20 ° C. and 60 to 75% atmospheric humidity. The final packaging then takes place.

Abstract

L'invention concerne un procédé de production d'un produit de tabac à fumer. Ce procédé qui permet de réaliser un produit de tabac à fumer, d'un genre nouveau, comprend les étapes suivantes: a) production d'une matière mixte comprenant des particules de tabac, de l'amidon ou un produit contenant de l'amidon comme liant et des additifs; b) la matière mixte est comprimée dans une extrudeuse par apport d'énergie thermique et mécanique, puis plastifiée; c) de la vapeur d'eau sous pression est ensuite injectée dans la matière mixte de manière à former des canaux; d) à sa sortie de l'extrudeuse, la matière mixte plastifiée à laquelle les canaux de passage ont conféré une structure poreuse, est expansée et moussée sous l'effet de l'abaissement de la température et de la pression, elle est solidifiée sous forme de jonc continu, cylindrique et poreux, puis est mise aux longueurs voulues.
