The flavoring agent is peppermint essence, the atomizing agent is a mixture of glycerol and propylene glycol with a mass ratio of 3:1, the binder is carboxymethyl cellulose, and the outer fiber is broadleaf wood bleached kraft pulp.

[0050] 1.2 The mixed slurry is rolled through a 5-stage roller pressing device. The thickness of the sheet gradually decreases after each stage of roller pressing, and finally a sheet strip with a thickness of about 0.2 mm is formed. The sheet strip is dried in a drying system at a drying temperature of 90-110°C. After drying, the moisture content of the sheet strip is about 8%, and the tensile strength is about 0.34 KN / m.

[0065] Example 3

[0066] A heated cigarette using a herbaceous plant and a method for preparing the same, comprising the following steps:

[0067] 3.1 Green tea powder is used as a raw material and is ground to 250-300 mesh. The ground powder is mixed with atomizing agent, flavoring agent, water, binder, and fiber in a mass ratio of 100:25:15:45:2:10 to form a slurry. The flavoring agent is a mixture of peppermint essence and blueberry extract, and is intended to highlight the ice berry flavor. The atomizing agent is a mixture of glycerol and propylene glycol in a ratio of 2:1. The binder is carboxymethyl cellulose, and the fiber is broadleaf wood bleached kraft pulp.

[0068] 3.2 The mixed slurry is rolled through 5 stages of rolling equipment. The thickness of the sheet gradually decreases after each stage of rolling, and finally a sheet strip with a thickness of about 0.30 mm is formed.

[0074] Comparative Example 1

[0075] A heated cigarette using a herbaceous plant and a preparation method thereof, comprising the following steps:

[0076] 1.1 A tea leaf of a vine tea is used as a raw material, which is ground to 250-300 mesh. The ground raw material with powder is mixed with an atomizing agent, a flavoring agent, water, a binder, and fibers in a mass ratio of 100:25:15:60:1:7 to form a slurry. The flavoring agent is a mixture of peppermint essence and pineapple extract, aiming to highlight the ice-pineapple flavor. The atomizing agent is glycerol. The binder is carboxymethyl cellulose, and the outer fibers are bleached kraft pulp.

[0077] 1.2 The mixed slurry is rolled by a 5-stage roller pressing device, and the thickness of the sheet gradually decreases after each stage of rolling, and finally a sheet strip having a thickness of about 0.15 mm is formed. The sheet strip is dried by a drying system, the drying temperature being 100-110°C. After drying, the moisture content of the sheet strip is about 12%, the tensile strength is about 0.51 KN / m, and the basis weight is 257 g / m 2 .

[0078] 1.3 The dried sheet is cut into strands, the cut sheet strands having a length of about 30 mm, a width of about 1.1 mm, and a thickness of about 0.18 mm.

[0079] 1.4 The cut thin slice filament is rolled by a cigarette machine to form a smoking section, and the smoking section and a filter section are rolled by a cigarette paper to form a finished cigarette (the content of each thin slice filament is about 0.25-0.28 g). Because the moisture of the thin slice filament is high, the machine effect is poor during the cigarette rolling process, and the machine is prone to stop. The temperature of the first two puffs of smoke is obviously high, which easily causes discomfort to consumers. The finished cigarette is subjected to sensory evaluation, and 10 points are full marks. The higher the score, the better the result. The results are shown in Table 7.
