Technical Field
The invention relates to the field of production of heating cigarette products, which prevents water in the external environment from diffusing into cigarettes by sealing the end of a cigarette core end of each cigarette by adopting a thermoplastic material, is beneficial to realizing the drainage and moisture prevention of the cigarettes and belongs to the field of production and processing of heating leaf-rolled products.
Background
The reconstituted tobacco used in the heating non-combustion cigarette products in China mainly adopts five types of preparation processes of a paper-making method, a paper-making thick pulp compounding method, a thick pulp method, a rolling method and a dry paper-making method. Different from the traditional cigarette products, the glycerin is added into the heated cigarette as a smoke agent, and the heated cigarette is heated by the heat source temperature between 200 ℃ and 400 ℃ so that the effective components in the tobacco materials are volatilized. The addition of the glycerin causes the reconstituted tobacco to be extremely easy to absorb moisture, and the increase of the moisture in the reconstituted tobacco is easily caused by the high relative humidity in the production or storage environment, thereby seriously influencing the quality stability and sensory evaluation performance of the heated cigarette product.
The regulation and control of the moisture absorption performance of the reconstituted tobacco become a great challenge for restricting the improvement of the comprehensive competitiveness of the industry heating cigarette products. Compared with the moisture absorption risk of the reconstituted tobacco special for the heating cigarette developed by international tobacco companies, the moisture absorption risk of the reconstituted tobacco is obviously improved in the domestic industry, and the product stability is high; the research on the field of regulating and controlling the moisture of the reconstituted tobacco special for the heated cigarette is still in the initial stage, so that the research on the moisture absorption performance regulating and controlling technology of the reconstituted tobacco special for the heated non-burning cigarette has strong urgency for the domestic tobacco industry.
At present, a method for achieving moisture resistance by sealing the end part of a cigarette core section of a heated non-burning cigarette is rarely reported.

3) Packaging the end part of the cigarette core: the end part of the cigarette core section of the heating non-combustion cigarette product is sealed by the edible biodegradable film subjected to hydrophobic treatment by adopting a hot air gun and a sealing machine, and pressure is applied to the end part of the cigarette core section to ensure that the edible biodegradable film is tightly attached to the end part of the cigarette core section.
In the step 1), the plant starch includes but is not limited to one or more of sweet potato powder, corn powder, wheat flour and the like. Edible celluloses include, but are not limited to, methylcellulose, carboxymethylcellulose. The protein matrix includes but is not limited to one or more of soy protein isolate, wheat gluten protein extract, whey protein, etc. The release agent includes but is not limited to talc, glycerin, polytetrafluoroethylene, paraffin and the like.
In the step 2), the long-chain fatty alcohol refers to one or more of aliphatic alcohols with 12-22 carbon atom chains.
In the step 3), the pressure applied to the end part of the cigarette core section refers to 1.5-3.5 atmospheric pressures.
The invention has the advantages that: the end part of the core section of the heating non-combustion cigarette product is sealed by adopting the edible biodegradable film subjected to hydrophobic treatment, so that moisture in the environment is prevented from diffusing to the inside of the core section through the end part of the core section, and the moisture, glycerol and other components in the heating cigarette product are delayed from migrating and diffusing to the outside; on the other hand, the hydrophobic agent adopted by the edible biodegradable film is nonpolar long-chain fatty alcohol, has certain antibacterial activity, improves hydrophobicity and can delay bacterial breeding of cigarette products. The sealing film has no toxic and harmful substance escaping in the using process, and the cigarette can be placed in the heating smoking set for use after being automatically removed before the cigarette consumption. The method provides an operable method for optimizing the moisture resistance of the heated non-combustion cigarette product and stabilizing the product quality.
