Definitions

  • the invention relates to a method for producing a smokable tobacco product.
  • DE-33 39 241 C1 describes a process for the production of revealed crimped pieces of fiber from recycled tobacco, for tobacco dust and / or tobacco waste with binders and possibly additives to a plasticizable mixture are processed.
  • a cylindrical extruder is used Strand from the plasticized mixture to a thin-walled, continuously expanding hollow body reshaped and in filamentary, ruffled intermediates divided that then cut into individual, crimped fiber pieces.
  • DE-38 19 534 C1 discloses a process for the production of pieces of tobacco foil from recycled tobacco.
  • Here becomes dusty tobacco waste and / or tobacco flour with binders and possibly additives mixed and the resultant Plasticized mixture in an extruder.
  • the plasticized Mixture is made into a straight line via flow paths of exactly the same length Number of mechanically / geometrically identical cylindrical Strands divided. Two adjacent, identical ones Strands are rolled into a film strip, which is then is cut into pieces of film.
  • Plasticizing the Mixtures in the extruder take place at temperatures from 90 to 120 ° C and pressures from 50 to 100 bar.
  • the cylindrical Strands have a diameter of 2 to 7 mm.
  • DE-40 05 656 A1 describes a method for producing a described tobacco-containing film with increased filling power.
  • the moist raw mass is then in an extruder with a temperature profile of approx. 30 ° C to approx. 160 ° C a pressure of approx. 10 to approx. 200 bar and extruded through pressed through a nozzle provided with an outlet gap, which creates the tobacco foil.
  • This tobacco foil will then Heavily heated on both sides, causing it to stick to the tobacco foil form largely gas impermeable cover layers.
  • Another strong supply of heat is the tobacco foil Any water present between the outer layers evaporates, causing bubble-shaped cavities arise.
  • the invention has for its object a novel smokable tobacco product or a process for its production to develop.
  • the generated by the introduction of water vapor in the mixed mass Channels remain longitudinal in the extruded strand and radial channels.
  • the same process takes place as with a conventional one manufactured tobacco rod with the difference that the Combustion air through the solidified air channels instead of through Gaps in the cut tobacco is sucked.
  • the strand produced according to the invention is permeable to air, that the combustion air when smoking is even is sucked through the strand cross-section and the strand length, where the tensile resistance given by the strand is one does not exceed the upper value.
  • the proportion of the binder advantageous is about 15% by weight.
  • Humectants can be added as additives, such as e.g. B. glycerin, molasses and / or other hygroscopic Fabrics.
  • Fire improvers can also be provided as additives e.g. B. organic acids to produce a white fire Ash and / or carbonates or wetting agents to improve the Smoldering ability.
  • flavors and / or flavorings can also be used as additives be provided such.
  • Advantageous additives are also film-forming additives biological basis.
  • PVA polyvinyl alcohol
  • PVAC polyvinyl acetate
  • the tobacco particles used for the mixed mass can be can produce by shredding mature tobacco leaves but also waste from conventional tobacco processing be. Tobacco particles are preferably in a sieve size from about 3 to 5 mm.
  • the mature tobacco packaged in the trade has a lengthy process undergone biochemical development: even before Leaf harvesting still occurs in the tobacco on the field, that after harvest with increasing yellowing, drying and Fermentation is continued.
  • the chemistry of ripening is depends essentially on the slowest possible water loss.
  • the initially relatively high concentrations in the vital state of starch and protein with a high water content up to about 80% by weight hydrolyzed and in soluble sugars and transferred nitrogen compounds. With a water content ⁇ 80% the ferments that trigger these processes become inactive; the so-called leaf death occurs.
  • it is therefore desirable to dry to be completed within 100 hours; during this Time will raise the temperature from 32 ° C to 80 ° C and the relative humidity from 80% to 10% with increasing Increase the ventilation shutdown.
  • the invention will now be used proposed to manufacture the tobacco particles for the above
  • the mixed mass described has not yet matured tobacco leaves to use and crush, then the ripening of the tobacco in the extruded strand, i.e. in the almost finished product perform.
  • the manufactured according to the invention String sections in a ventilated, climate-controlled environment conditioned, i.e. in air-permeable containers in climate controlled chambers. This is where the conditioning takes place up to a final moisture content of about 10 to 13% at about 50 ° C. The transfer then takes place in this state in the last stage of production:
  • the so-called "aging” consists of storing the strand sections over a period of about 0.5 to 2 years 20 ° C and 60 to 75% humidity. Then the Final packaging instead.
