Description

Technical Field

[0001] The invention relates to the technical field of preparation of explosive beads for cigarettes, and in particular to a method for preparing explosive beads for cigarettes by a chemical film-forming method. Background Art

[0002] As a filter rod additive, cigarette popping beads can not only improve the taste of cigarette smoke, but also optimize user experience and enhance the brand's favorability in the market. The preparation process and physical indicators of popping beads have attracted the attention of major companies. At present, the preparation methods of cigarette popping beads in the domestic market are mainly physical film formation and chemical film formation.

[0003] The physical film-forming method is suitable for the production of large quantities of popping beads, and the one-time feed volume is large. The physical film-forming method for the production of popping beads for tobacco mainly includes pulse cutting molding process and gravity cutting molding process. The essential oil solvent in the pulse cutting process is an olive oil system, while the essential oil solvent in the gravity cutting process is a caprylic decanoic acid glyceride system. Because there is compatibility between the popping bead core liquid and the capsule material, neither the pulse cutting molding process nor the gravity cutting molding process can be simultaneously adapted to the production of flavors whose solvents are one or more of olive oil, caprylic decanoic acid glyceride, propylene glycol, glycerol, ethanol, and water.

[0004] The chemical film-forming method is suitable for the preparation of a small amount of popping beads. It has the advantages of wide compatibility with flavor solvents, low equipment requirements, short dripping process, small amount of flavor demand and small flavor loss. It is suitable for the research and development of popping bead flavors for tobacco and technological updates. Therefore, it is particularly important to develop a new method for preparing popping beads for tobacco to enrich the production methods of popping beads. Summary of the invention

[0005] The purpose of the present invention is to provide a method for preparing tobacco popping beads by a chemical film-forming method, which is used to solve the problems in the prior art of single popping bead flavor solvent, high equipment requirements, long dripping process, large flavor demand, easy loss of flavor and unstable finished product quality.

[0015] Further: the essential oil or fragrance solvent system includes one or more of olive oil, caprylic glyceride, isopropyl myristate, 1,2-propylene glycol, dipropylene glycol, ethanol, and water.

[0016] Furthermore: the emulsifier includes one or more of polyoxyethylene monolaurate, sucrose fatty acid ester, polyoxyethylene monostearate, polyoxyethylene oleyl ether, and sodium oleate, and the HLB value of the emulsifier is 10.0-18.0.

[0017] Further: the plasticizer includes at least one of di-n-butyl phthalate, acetyl tributyl citrate, and polyethylene glycol.

[0018] Furthermore: the conductivity of the ultrapure water at 35° C. is ≤0.056 μS / cm, and the resistivity is ≥18.2 MΩ·cm.

[0019] Further: in step 1, the emulsion is stirred for 25 to 30 minutes under a stirrer with a rotation speed of 1500 to 2000 rpm.
