Problems solved by technology

However, due to the poor heat transfer performance of the wick material, the heat cannot be rapidly diffused to the whole wick material during heating, causing the thin slices near the heat source to overheat and burn easily, while the thin slices far away from the heat source are not heated sufficiently, making The amount of smoke and the release of aroma components are uneven, and occasionally there will be odors, which seriously affect the sensory quality of the product
[0006] In addition, there are differences in the structure and performance of the cigarette core materials produced by different processes, and the loads of smoking agents and flavor components are not the same. The overall smoke core materials suitable for heat-not-burn cigarettes are limited, resulting in the limitation of the smoke core materials. Utilization rate is not high

Embodiment 1

[0031] Weigh 50g of gum arabic and mix with 500g of deionized water, stir and heat to 50°C, and make the two fully mix to obtain edible gum solution A.

[0032] Take 100g of heat-conducting salt (binary salt) and grind it through a 40-mesh sieve, sprinkle the heat-conducting salt powder evenly in the edible glue solution A, heat the mixture to 200°C to melt the heat-conducting salt, and stir the mixture evenly to prepare the heat-conducting salt coating Liquid B.

[0033] Take 2 kg of paper-making wick material, add glycerin evenly according to 15% of the mass of the wick material, and then evenly spray heat-conducting salt coating solution B on the surface of the wick material. The treated wick material was placed in a vacuum low-temperature drying oven, dried for 1 hour at a vacuum degree of 10 Pa and a temperature of -20° C., and then taken out to obtain a heat-not-burn wick material loaded with heat-conducting salt.

Embodiment 2

[0035] Weigh 50 g of carrageenan and mix with 250 g of deionized water, stir and heat to 100° C., so that the two are fully mixed, and edible gum solution A is obtained.

[0036] Take 30g of heat-conducting salt (ternary salt) and grind it through a 100-mesh sieve, sprinkle the heat-conducting salt powder evenly in edible glue solution A, heat the mixture to 250°C to melt the heat-conducting salt, and stir the mixture evenly to prepare the heat-conducting salt coating Liquid B.

[0037] Take 660g of roll-pressed tobacco core material, add propylene glycol evenly according to 25% of the mass of the tobacco core material, and then immerse in the heat-conducting salt coating solution B. After the smoke core material fully absorbs the heat-conducting salt coating solution B, place the smoke core material in a vacuum low-temperature drying oven, dry it at a vacuum degree of 50Pa and a temperature of 20°C for 10 hours, and then take it out to obtain a heat-not-burn product loaded wi...

Embodiment 3

[0039] Weigh 50g of guar gum and 100g of deionized water, mix them, stir and heat to 80°C, and mix them well to obtain edible gum solution A.

[0040] Take 30g of heat-conducting salt (binary salt) and grind it through an 80-mesh sieve, sprinkle the heat-conducting salt powder evenly in edible glue solution A, raise the temperature of the mixture to 230°C to melt the heat-conducting salt, and stir the mixture evenly to obtain a heat-conducting salt coating Liquid B.

[0041] Take 600g of thick slurry method cigarette core material, add glycerin evenly according to 20% of the mass of the cigarette core material, and then evenly brush the heat-conducting salt coating solution B on the surface of the cigarette core material. The treated wick material was placed in a vacuum low-temperature drying oven, dried at a vacuum degree of 20 Pa and a temperature of -10°C for 5 hours, and then taken out to obtain a heat-not-burn wick material loaded with heat-conducting salt.

Abstract

The invention discloses a preparation method of a heat-not-burn cigarette core material. The preparation method comprises the steps that a certain amount of edible gum and deionized water are heated and mixed to prepare a solution A; then the solution A and a certain amount of heat transfer salt powder are heated and mixed to prepare a coating liquid B; lastly, the coating liquid B is applied on the surface of the cigarette core material with a smoke producing agent, and after vacuum low-temperature drying and solidification treatment is carried out, the heat-not-burn cigarette core material is prepared. The cigarette core material prepared through the preparation method of the heat-not-burn cigarette core material has an excellent heat transfer property, a cigarette rolled with the cigarette core material cannot generate burnt phenomenon when heated, the amount of produced smoke is large, the fragrance components are emitted evenly and stably, the cigarette incense is abundant and soft, the tensile strength of the cigarette core material is effectively improved, strip cutting molding is easier, the practicability is very high, and the applicability is wide.

Description

technical field [0001] The invention relates to a method for preparing a cigarette core material, in particular to a method for preparing a heat-not-burn cigarette core material in the technical field of tobacco. Background technique [0002] In recent years, as smoking and health issues have attracted increasing attention, research and development of new tobacco products that can effectively reduce the release of harmful components of tobacco has become the development focus of the tobacco industry in various countries. Among them, representative new tobacco products include electronic cigarettes and heat-not-burn cigarette products. [0003] Heat-not-burn cigarette products use a heating source to heat the core material (the temperature generally does not exceed 500°C). After the core material is heated, the nicotine and flavor components contained in the core material are volatilized to produce smoke to meet the needs of consumers. Since the core material is heated inste...
