  • the plant fibers include one or more selected from the group consisting of hemp pulp, bamboo pulp and wood pulp.
  • the plant fibers are pulverized and defibered under an anhydrous condition to generate a base sheet by a dry air forming manner, which includes performing a destaticization process on monofilament fibers obtained by the pulverizing and defibering.

  • the production process mainly includes the processes of tobacco powder preparation, coating liquid formulation, base sheet forming, coating and drying, adding smoke agent and/or top-note-flavor type tobacco essence flavor, etc.
  • the tobacco raw materials may be pre-treated by means of microorganisms or bio-enzymes, etc., so that the macromolecular substances of the tobacco raw materials become micromolecular substances which facilitate the sensory quality for the products and volatilize more easily.
  • the pre-treated tobacco raw materials after being directly pulverized and screened, are all used in coating liquid formulation, prevent the loss of effective ingredients from the tobacco raw materials, and thereby improving the comprehensive utilization ratio of the raw materials.
  • the process of coating liquid formulation can not only achieve a basic function of the effectively mixing of the tobacco raw materials, adhesive, smoke agent, tobacco essence flavor and other minor ingredients, but also the demand that a large portion of materials e.g. smoke agent and tobacco essence flavor need to be added into the heat-not-burn cigarette core can be satisfied,.
  • This can not only avoid too viscous coating liquid due to the addition of a large portion of smoke agent and tobacco essence flavor or the like, which affects the coating process and thus leads to unstable product quality, but also ensures that no extra pressure will be created to the drying process, such that the process is adjustable, controllable and flexible.
  • the process of base sheet forming is a low quantitative base sheet forming process which can eliminate static flocculation. Not only is the process of base sheet forming applicable to a single addition of common plant fibers e.g. wood pulp, hemp pulp and bamboo pulp, but also the process of base sheet forming allows simultaneous additions of the aforementioned plant fibers, tobacco stems or even various raw fiber materials in special fibers such as tea steams, agarwood, agarwood leaf and liquorice fiber. The process has relatively good adaptability.
  • the process of adding smoke agent and/or top-note-flavor type tobacco essence flavor is an innovative means which is designed to avoid the drying process and ensures, in the case of fully-dried products, that the smoke agent and top-note-flavor type tobacco essence flavor have an obvious influence on the heat-not-burn cigarette quality and fully preserve the highly volatile ingredients. In this way, the qualities of the heat-not-burn cigarette core materials and the cigarette products made from such core materials are further guaranteed.
  • the smoke agent includes but is not limited to glycerol, propylene glycol and sorbitol
  • the top-note-flavor type tobacco essence flavor include but are not limited to burley tobacco absolute oil, cocoa extractive, tobacco leaf extractive and aromatic tobacco concrete.
  • the above materials may be directly added to the coating liquid or added separately, or may be added to the coating liquid after being processed by certain technical means, a method of which includes but is not limited to concentration and microencapsulation, so as to improve the stability and the retention rate of the above materials in the production process.
