Embodiment 1

[0094] (1) Stir the agar powder and water at a weight ratio of 1:1 and heat to boiling, and then stand at 20° C. to 30° C. for 12 hours to obtain aqueous agar.

[0095] (2) pre-freezing the water-containing agar into a solid in liquid nitrogen, drying the obtained solid in a freeze-drying machine for 24 hours, the vacuum degree of the freeze-drying is 1MPa, and the temperature of the freeze-drying is -35 ℃, obtains the dry agar, the thickness It is 1.0mm, and the appearance is a porous sponge-like white solid.

[0096] (3) Cut the dry agar into a suitable size, roll it into a roll, and wrap a layer of cigarette forming paper on the outside of the roll (see Figures 1 to 2 ) to obtain a cooling member 3-1 for smoke, which has a length of 20 mm and an outer diameter of 22.0 mm.

Embodiment 2

[0098] (1) Stir agar powder, activated carbon fiber, silica and water at a weight ratio of 2:1.35:0.75:1 and heat to boiling, and then stand at 20°C to 30°C for 14 hours to obtain aqueous agar.

[0099] (2) Pre-freeze the aqueous agar into a solid in a low temperature refrigerator (-40°C), and dry the obtained solid in a freeze dryer for 24 hours. The vacuum degree of freeze-drying is 0.5MPa, and the temperature of freeze-drying is -45°C. , to obtain dry agar with a thickness of 0.8 mm and a porous sponge-like black solid in appearance.

[0100] (3) Cut the dry agar into a suitable size, roll it into a roll, and wrap a layer of cigarette forming paper on the outside of the roll (see Figures 1 to 2 ) to obtain a cooling member 3-2 for smoke, which has a length of 20 mm and an outer diameter of 22.0 mm.

Embodiment 3

[0102] (1) agar powder, activated carbon fiber, kaolinite clay and water are stirred and heated to boiling at a weight ratio of 3:1.25:2:2, the obtained mixture is cooled to 30° C. and added with essence to continue stirring for 5 minutes, Wherein, the added amount of the essence is 50% of the total weight of the agar powder and water, and then the mixture is allowed to stand at 20° C. to 30° C. for 18 hours to obtain water-containing agar.

[0103] (2) the water-containing agar is pre-frozen into a solid in liquid nitrogen, the obtained solid is dried in a freeze dryer for 24 hours, the vacuum degree of freeze drying is 0.6MPa, and the temperature of freeze drying is -50 ° C to obtain dry agar, The thickness is 1.5mm and the appearance is a porous sponge-like black solid.

[0104] (3) Cut the dry agar into a suitable size, roll it into a roll, and wrap a layer of cigarette forming paper on the outside of the roll (see Figures 1 to 2 ) to obtain a cooling member 3-3 for smok...

Abstract

The invention belongs to the field of tobacco products, and specifically relates to a method for preparing a cooling material for tobacco, comprising the following steps (1), (2), (3) and optional steps (1-1): (1) mixing agar, water , an optional carbon material and an optional first substance are mixed to obtain a first mixture; wherein, the carbon material has a specific surface area of ​​100 to 3000 m 2 / g of one-dimensional carbon material and / or two-dimensional carbon material, the first substance is selected from at least one of Mohs hardness of 5-8 silica, Mohs hardness of 1-4 clay and nanocellulose; ( 1‑1) mixing the first mixture with the essence to obtain the second mixture; (2) freezing the first mixture or the second mixture to obtain a solid; (3) freeze-drying the solid to obtain a dry product. The invention also relates to the prepared tobacco cooling material and its application. The cooling material for tobacco prepared by the method of the invention has a significant cooling effect on heat-not-burn cigarettes.

Description

technical field [0001] The invention belongs to the field of tobacco products, in particular to a method for preparing a cooling material for cigarettes, and also relates to the obtained cooling material for cigarettes and its application in tobacco products. Background technique [0002] Heat-not-burn cigarettes (HnB) are a new type of tobacco products, which mainly heat the cartridge through a heat source to generate smoke for consumers to smoke in a non-combustible state, reducing the harmful smoke components generated by conventional cigarette combustion and thermal cracking. Generates sidestream smoke. When consumers use HnB, the temperature of the tobacco material in the heating section is generally lower than 500°C, but because the path from the suction nozzle to the heating section is short, a cooling component for smoking needs to be arranged between the heating section and the suction nozzle. [0003] Generally, HNB cigarettes consist of a cigarette heating part, ...
