[0079] Comparative Example 1

[0080] A heating cigarette using herbal plants and a preparation method thereof, comprising the following steps:

[0081] 1.1 Take rattan tea leaves as raw materials, crush them to 250-300 mesh, mix the crushed raw materials with powder, atomizer, flavoring agent, water, binder and fiber in a mass ratio of 100:25:15:60:1:7 to form a slurry. The flavoring agent is a mixture of mint essence and pineapple extract, which is intended to highlight the aroma of ice pineapple. The atomizer is glycerol. The binder is carboxymethyl cellulose, and the outer fiber is hardwood bleached kraft pulp.

[0082] 1.2 The mixed slurry is rolled through a 5-stage rolling device. After each stage of rolling, the thickness of the sheet gradually decreases, and finally a sheet with a thickness of about 0.15 mm is formed. The sheet is dried by a drying system at a drying temperature of 100°C~110°C. After drying, the moisture content of the sheet is about 12%, the tensile strength is about 0.51 KN / m, and the basis weight is 257 g / m 2 .

The rolled smoking section and filter section are rolled with cigarette paper to obtain finished cigarettes (the content of each thin slice is about 0.25~0.28 g). Due to the high moisture content of the thin slices, the machine effect is not good during the cigarette rolling process, and the machine is prone to stop. The temperature of the smoke in the first two puffs is obviously high, which can easily cause discomfort to consumers. The finished cigarettes are evaluated by sensory evaluation, with 10 points as the full score. The higher the score, the better the result. The results are shown in Table 7.
