Embodiment 1

[0055] A method for preparing particles for heating cigarettes, comprising the following steps:

[0056] Step 1, raw material pretreatment, the selected leaf group raw material is roasted to remove miscellaneous gas, and the moisture content is adjusted to 6wt% at the same time.

[0057] Step 2, crushing and grading the raw material, the tobacco leaf raw material is first crushed, and the raw material after the primary crushing is then ultrafinely crushed, and the outlet of the pulverizer is set at an 80-mesh mesh to obtain the crushed raw material. The pulverized raw materials are classified to separate 80-150 mesh powder, 150-200 mesh powder and powder with particle size less than 200 mesh.

[0058] Step 3, raw material primary treatment. Mix the tobacco powder with a particle size of 150-200 mesh and the tobacco powder with a particle size of less than 200 mesh at a mass ratio of 10:1. After the mixed powder is mixed evenly, add flavor and smoke agent. The smoke agent is ...

Embodiment 2

[0071] A method for preparing particles for heating cigarettes, comprising the following steps:

[0072] Step 1, raw material pretreatment, the selected leaf group raw material is roasted to remove miscellaneous gas, and the water content is adjusted to 12wt% at the same time.

[0073] Step 2, crushing and grading the raw material, the tobacco leaf raw material is first crushed, and the raw material after the primary crushing is then ultrafinely crushed, and the outlet of the pulverizer is set at an 80-mesh mesh to obtain the crushed raw material. The pulverized raw materials are classified to separate 80-150 mesh tobacco powder, 150-200 mesh tobacco powder and tobacco powder with particle size less than 200 mesh.

[0074] Step 3, raw material primary treatment. Mix the tobacco powder with a particle size of 150-200 mesh and the tobacco powder with a particle size of less than 200 mesh, the mixing mass ratio is 20:1, and after the mixed powder is mixed, add flavor and smoke a...

Abstract

The invention belongs to the technical field of cigarettes, and particularly relates to particles for heating cigarettes and a preparation method thereof. Each particle comprises a particle core and a particle shell; the particle cores are prepared from core tobacco powder, a core smoking agent and a core spice component; and the particle shells are prepared from shell tobacco powder, a shell smoking agent, a shell spice component and heat conduction material particles. The hygroscopicity of the core smoking agent is larger than that of the shell smoking agent; the boiling point of the core spice component is lower than that of the shell spice component; and the particle size of the core tobacco powder is smaller than that of the shell tobacco powder. Through combination of raw material grading treatment, screw extrusion granulation and rotary granulation, the problems of moisture absorption and unstable fragrance release of particles are solved. The process is simple and easy to operate, equipment is commercially available conventional equipment, and batch production can be realized.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to particles for heating cigarettes and a preparation method thereof. Background technique [0002] At present, the granules for granule-type heating cigarettes are prepared by one-time granulation process, most of them adopt wet granulation, and a small part adopt direct crushing and screening. Among them, most of the directly crushed and sieved are expanded tobacco stem particles, which have a certain ability to absorb smoke, but are extremely hygroscopic, requiring extremely high requirements for later product packaging, and are prone to quality accidents. Most of the wet granulation preparation process adopts rotary extrusion granulation. The granules have strong plasticity and relatively loose structure, but there are still problems of moisture absorption and aroma retention. Invention patent CN112716029A discloses a nano-microcapsule for granular heating cigare...
