Problems solved by technology

The thin slices suitable for HNB cigarettes are made into cigarettes for rolling. The modified thin slices are relatively stiff and have poor curling performance. There is a big difference in appearance and physical properties from traditional natural leaf silk. With the use of a large proportion of adhesives and other external additives, the rolled cigarettes will produce a large amount of non-tobacco odor during the heating process, which will affect the smoking quality of the cigarette factory

Embodiment 1

[0024] A multi-stage atomizing agent feeding process, comprising the following steps:

[0025] a. Leaf silk pretreatment: the incoming leaf silk enters the microwave heating process, the microwave magnetron is turned on at a ratio of 60%, and the leaf silk is warmed. Silk insulation. Dissolving the rosin into an ethanol solution with a concentration of 75% to obtain a rosin solution with a concentration of 15%, spraying the rosin solution to the insulated leaf silk, so that the mixing mass ratio of rosin and the leaf silk is 3:100, and then the leaf silk is heated to 125°C and heated for 4h.

[0026] b. Feeding: According to parts by mass, mix 9 parts of glycerol and 1 part of ethanol with a concentration of 70% to obtain an atomizing agent, and heat the atomizing agent to 95°C by steam to reduce its viscosity for use.

[0027] After microwave heating, the leaf silk enters the multi-stage micro-unit feeding process. The multi-stage micro-unit feeding machine includes a trans...

Embodiment 2

[0033] A multi-stage atomizing agent feeding process, comprising the following steps:

[0034] a. Leaf silk pretreatment: Dissolve the rosin into an ethanol solution with a concentration of 75% to obtain a rosin solution with a concentration of 10%, and spray the rosin solution to the leaf silk at room temperature, so that the mixing mass ratio of rosin and leaf silk is 1:100, The leaf silk was then heated to 120°C and heated for 3h.

[0035] b. Feeding: According to mass parts, mix 8 parts of glycerol and 1 part of ethanol with a concentration of 70% to obtain an atomizing agent, and heat the atomizing agent to 90 ℃ by steam to reduce its viscosity and prepare it for later use. At 65°C, the heated atomizing agent was directly sprayed to the leaf silk, and the mixing mass ratio of the atomizing agent and the leaf silk was 18:100.

[0036] c. Drying: Use hot air at 120°C to dry to a moisture content of 12%.

[0037] d. For silk storage, the dried finished leaf silk is stored...

Embodiment 3

[0040] A multi-stage atomizing agent feeding process, comprising the following steps:

[0041] a. Leaf silk pretreatment: Dissolve rosin into 75% ethanol solution to obtain a 20% rosin solution. After heating the leaf silk to 130°C, spray the rosin solution onto the leaf silk, so that the rosin and the leaf silk are mixed with each other. The mixing mass ratio is 5:100, and the temperature is kept for 5h.

[0042] b. Feeding: According to mass parts, mix 10 parts of glycerol and 1 part of ethanol with a concentration of 70% to obtain an atomizing agent, and heat the atomizing agent to 100 ℃ by steam to reduce its viscosity for use.

[0043]One-time feeding: using the multi-stage micro-unit feeding in Example 1, that is, the thickness of the leaf silk is 10 mm, the air pressure is used to induce the spraying agent, the air pressure of the injection is 0.28 mpa, the temperature of the feeding cavity is controlled to 90 ° C, and the atomization is carried out. The mixing mass ra...

Abstract

The invention relates to the technical field of heat-not-burn cigarettes, in particular to a multi-stage atomizing agent feeding process. It includes the following steps: pretreatment of leaf silk: dissolving rosin into an organic solvent to obtain a rosin solution, spraying the rosin solution to the leaf silk, and heating at 120-130° C. for 3-5 hours; feeding: selecting a mist containing glycerol After heating the atomizing agent to 90~100°C, spray the pretreated leaf silk at 65~90°C; drying: dry the leaf silk after the feeding is completed. The application solves the problems that the traditional leaf silk atomizer is difficult to apply and the oily glycerol substances are difficult to absorb by the leaf silk. The absorption ratio of the leaf silk to the atomizer reaches more than 80%, and the rapid absorption in a short time can be achieved. Compared with the prior art, the appearance of the leaf silk is not changed, the physical properties are basically the same as the traditional leaf silk, no adhesive substances are added, and a large amount of non-tobacco smell is not generated during the heating process, which improves the core sensory quality of the cigarette.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to a multi-stage atomizing agent feeding process. Background technique [0002] As a new category of tobacco products, HNB (heat not burn) cigarettes have developed rapidly in recent years, representing a development trend of cigarette products in the future. As a new type of cigarette, the heating method of the smoking process is very different from that of traditional cigarettes, and the requirements for the characteristics of the materials in the smoking section of cigarettes are also completely different. A large proportion of the atomizer (the main component is glycerol), the application ratio is more than 20%, and smoke is generated during the heating process. [0003] Glycerol is an oily substance, and traditional leaf silk is difficult to absorb. Therefore, the main method currently used is to pulverize tobacco leaves, tobacco stems and other substances int...
