Definitions

  • the present invention relates to the field of tobacco, and in particular relates to a heat-not-burn reconstituted tobacco and a process for manufacturing the reconstituted tobacco.
  • both smoked tobaccos include cut tobacco, tobacco fragments, tobacco particles, tobacco waste, and the like.
  • a heat-not-burn type heating tobacco product is smoked with a lower temperature at a tobacco site, which only heats the tobacco and does not burn the tobacco, so that tar production can be greatly reduced.
  • the temperature control of tobacco product heating is more precise, which can be more effective in avoiding excessive temperatures of a smoke-generating article, and preventing the overflow of more harmful substances.
  • Patent documents CA3135252A1 , CA2875167A1 and CZ291606B6 disclose reconstituted tobacco products that are used in devices for heating tobacco or in cigarettes.
  • the present invention aims to provide a reconstituted tobacco to improve the smoke-generating amount and stability of the reconstituted tobacco.
  • a reconstituted tobacco having a mass per unit area of 100-190 g/m 2 , a thickness of 0.13-0.18 mm and a density of 700-1400 mg/cm 3 , wherein a mass percentage of an atomization agent in the reconstituted tobacco is 15-30% and wherein a mass percentage of a tobacco matter in the reconstituted tobacco is 65-80%.
  • the thickness of the reconstituted tobacco refers to a dimension between the upper and lower surfaces of the reconstituted tobacco, and can be obtained by measurement.
  • the density of the reconstituted tobacco can be obtained through calculation by measuring the mass and volume of the entire reconstituted tobacco prior to cutting into shreds.
  • a combination of the mass per unit area, thickness, density and atomization content of the reconstituted tobacco of the present invention can advantageously improve the heat conduction properties of the reconstituted tobacco, and enables liquid components of the reconstituted tobacco to be controlled within a reasonable range.
  • the increase in water content can be slowed down, ensuring quality stability of a formed smoke-generating body, resulting in a more excellent smoke-generating effect of the final smoke-generating body.
  • the density of the reconstituted tobacco indicates the compactness of smoke-generating components of the reconstituted tobacco in a three-dimensional space, which has a large impact on thermodynamic performance.
  • An increase in mass per unit volume means that there are fewer pores inside the sheet and less air is contained. Air has a much lower thermal conductivity than a general solid, so the sheet with fewer pores has a higher thermal conductivity, and conducts heat quickly, facilitating the reconstituted tobacco to absorb and transfer more heat when heated.
  • the excessive density of the reconstituted tobacco can result in an increase in specific heat capacity, and even if more heat is absorbed, the temperature rise of the sheet is small, and it is difficult to release smoke.
  • the density of the reconstituted tobacco is controlled to be 700-1400 mg/cm 3 .
  • the thickness of the reconstituted tobacco directly affects its processability resistance during subsequent processing of cigarettes.
  • the reconstituted tobacco with a large thickness is bent under stress, its folding resistance is reduced due to a large difference in the stress change between its two surfaces.
  • the thickness is too large, then when a sheet is processed into shreds or when cut reconstituted tobacco is rolled into cigarettes, it is easy to cause the fracture of the cut reconstituted tobacco, which affects the length of the cut reconstituted tobacco, produces more broken cut tobacco and tobacco waste, and in turn affects the filling properties of the cut reconstituted tobacco, and the integrity of the end face of the cut tobacco of the cigarette, resulting in reduced stability of the reconstituted tobacco, and meanwhile, also affecting the smoke-generating effects of the entire rolled smoke-generating body due to unguaranteed filling properties.
  • the thickness of the reconstituted tobacco also affects the degree of curling after the reconstituted tobacco is cut into shreds, which in turn affects the filling properties of the cut reconstituted tobacco.
  • the absolute content of a tobacco matter and an atomization agent is insufficient, which affects the smoke-generating amount of cigarettes and is not conducive to presenting a strong aroma.
  • the thickness of the reconstituted tobacco is set to 0.13-0.18mm, which can avoid the increase of the curvature after the reconstituted tobacco is cut into shreds, while ensuring folding resistance.
  • the water content of the reconstituted tobacco is controlled. This is because moisture is detrimental to smoke formation and gaseous water produced after the reconstituted tobacco is heated affects the atomization effect of the atomization agent.
  • the current manufacturing method has controlled the water content within a reasonable range before rolling the reconstituted tobacco, the reconstituted tobacco itself will absorb a certain amount of moisture in a short time before it is packaged, resulting in excessive water content of the smoke-generating body when it is rolled into a smoke-generating body.
  • the mass per unit area of the reconstituted tobacco indicates the compactness of smoke-generating components of the reconstituted tobacco on a plane.
  • the inventors found through research that the mass per unit area on a flat surface has a greater influence on the rate of water absorption. If the reconstituted tobacco has a lower mass per unit area, higher in-plane filling power and roughness are caused, and the water absorption capacity is higher, which in turn affects the rate of water absorption. In addition to the atomization agent contained in the reconstituted tobacco, the water absorption capacity in the plane of the tobacco is further increased.
  • the mass per unit area of the reconstituted tobacco is too large, the effect of reducing the rate of water absorption is diminished, and it is also unfavorable for the release of nicotine and smoke.
  • the mass percentage of the atomization agent in the reconstituted tobacco needs to be controlled at 15-30%. Too low content results in insufficient smoke-generating amount, and too high content results in a higher specific heat capacity of cigarettes, and a slow temperature rise and also a large smoke volume cannot be achieved. In addition, too high content of the atomization agent can also accelerate the water absorption rate of the reconstituted tobacco.
  • the mass per unit area of the reconstituted tobacco to be 100-190 g/m 2
  • the thickness to be 0.13-0.18 mm
  • the density to be 700-1400 mg/cm 3
  • the reconstituted tobacco has a density of 900-1100 mg/cm 3 , and a better smoke-generating effect is achieved.
  • the reconstituted tobacco has a mass per unit area of 150-190 g/m 2 , and the water absorption rate of the reconstituted tobacco within this range is low, and generally the water content of the tobacco does not significantly change prior to rolling during production, leaving sufficient time for the rolling process of cigarettes.
  • the nicotine release rate of the reconstituted tobacco within this mass per unit area range is significantly improved.
  • the reconstituted tobacco of the present invention it is more appropriate to control the water content of the reconstituted tobacco to be 4-8%. It is found through research that the higher the water content in the smoke formed is after the reconstituted tobacco is heated, the weaker the smoke visual effect of the aerosol formed is. If the water content of the reconstituted tobacco is too low, its brittleness will be enhanced and its folding resistance will be reduced. In the processing process, when the reconstituted tobacco is subjected to a force perpendicular to the plane of the sheet, it is easy to break, resulting in the increase of broken cut tobacco content.
  • the mass percentage of the atomization agent in the reconstituted tobacco is 20-25%.
  • the reconstituted tobacco within this range can maintain sufficient smoke-generating amount while still maintaining significant smoke-generating amount after a number of puffs without making the cigarettes too moist.
  • the atomization agent includes, but is not limited to, one or more of glycerol, and propylene glycol, more preferably the atomization agent employs glycerol. When glycerol is used as the atomization agent, less peculiar smell is produced.
  • the mass percentage of a tobacco matter in the reconstituted tobacco is 65-80%.
  • the percent mass of the tobacco matter in the reconstituted tobacco directly affects the sensory quality of the reconstituted tobacco during smoking, and the content of the tobacco matter being 65-80% is conducive to the formation of smoke with strong tobacco flavor.
  • the tobacco matter may be different types of tobacco raw materials such as flue-cured tobacco, air-cured tobacco, sun-cured tobacco, open-flame flue-cured tobacco, aromatic tobacco, and the like.
  • the tobacco matter used may be de-stemmed leaves, and stems of the tobacco. More preferably, the tobacco matter used preferentially selects de-stemmed leaves, because the lignin content is less and the aroma substances are more in the leaves, which is advantageous for enhancing the smoking taste of the reconstituted tobacco.
  • the reconstituted tobacco may also include essence or spices.
  • the essence and spices can be used as a supplement of aroma substances, and can be added according to the sensory quality design goal, generally 0-15%, to increase the tobacco flavor or give other flavor characteristics to the reconstituted tobacco.
  • the tensile strength of the reconstituted tobacco of the present invention can reach 0.4 kN/m or above.
  • a water content increment within 1h is less than 0.6% at 22°C, and 65 RH%. Ensuring a tensile strength of 0.4 kN/m or above can significantly reduce the generation of broken cut tobacco.
  • the reconstituted tobacco of the present invention has a tensile strength of 0.4-0.5 kN/m.
  • the reconstituted tobacco of the present invention has a water content increment of less than 0.6% within 1h after being unpacked under the temperature and humidity (22°C, 65 RH%) environment in a general cigarette production workshop, which is very beneficial to the control of the water content of cigarettes.
  • the present invention provides a smoke-generating body, including the reconstituted tobacco.
  • the smoke-generating body has a better smoke-generating amount when used, debris is not likely to fall off at the end of the smoke-generating body, and the smoking experience is good.
  • the present invention also provides a process for manufacturing the reconstituted tobacco, including steps of preparing tobacco raw materials into tobacco powder; mixing water, an atomization agent and an adhesive to prepare a wet material; mixing the tobacco powder with the wet material to prepare a formed sheet; and drying the formed sheet to obtain the reconstituted tobacco.
  • preparing the tobacco raw materials into the tobacco powder includes incoming material blending, impurity removal, moisture conditioning, coarse crushing, and fine grinding.

  • Impurity removal refers to removal of non-tobacco substances such as metal, plastic, etc. in raw materials, and can be achieved by a metal detector or winnowing.
  • Moisture conditioning means that ultra-fine tobacco powder should have a water content of 12% or less before crushing, if the water content is too high, the brittleness of the tobacco is insufficient, which is not conducive to crushing, if the crushing time is too long, it is easy to heat the tobacco material, and then the original flavor of the tobacco is changed. For example, there will be a burnt taste, which makes the sensory quality of the reconstituted tobacco poor.
  • the incoming tobacco sheet or stem When an incoming tobacco sheet or stem has a moisture content of 12% or above, the incoming tobacco sheet or stem should be dried by drying equipment such as an oven or a drying barrel to reduce the moisture content to 12% or less, and then crushed.
