A method for manufacturing non-combustible cigarettes based on flocking technology

Abstract

The invention belongs to the technical field of heating cigarette manufacturing, in particular to a method for manufacturing non-combustible cigarettes based on flocking technology. The method includes a flocking process and a cigarette rolling process; wherein, the flocking process includes a flocking step, and the flocking step is to flock the tobacco filler (1) on the cigarette paper. The present invention proposes a method for manufacturing non-combustible cigarettes based on flocking technology for the first time. The flocking process is used to automatically flock filamentous, fibrous or granular tobacco to the surface of cigarette paper, and then connect the cigarette rolling process to obtain non-combustible cigarettes. Burning cigarettes. When the cigarette stick contains tobacco filler particles, the complicated process of using a plugging device at the opening end of the cigarette stick is omitted. When the cigarette is filled with filaments or fibers of tobacco filler, the thermal resistance of heat propagating in the radial direction of the cigarette is greatly reduced, and the defects of large thermal resistance, slow heat transfer rate and uneven heating of the existing cigarette are improved.

Description

technical field [0001] The invention belongs to the technical field of heating cigarette manufacturing, in particular to a method for manufacturing non-combustible cigarettes based on flocking technology. Background technique [0002] In recent years, the sales volume of commercially available new heat-not-burn tobacco products represented by iQOS has continued to rise, and the recognition and acceptance of consumers have increased significantly. Its heat-not-burn tobacco sticks (cigarettes) are closer to the shape of traditional cigarettes. The tobacco filler in the tobacco rod is a filamentous filler, which is arranged along the axial direction of the cigarette rod, and the tobacco rod (cigarette rod) is heated by inserting the central heating sheet of the tobacco rod along the axial direction of the tobacco rod to generate inhalable smoke. Another type of heat-not-burn tobacco product represented by ploom tech adopts the pod (capsule) form between the traditional cigarett...

AI Technical Summary

Problems solved by technology

[0005] 1. Tobacco stick-type heat-not-burn products take a long time to warm up. Since the filamentous tobacco filler tightly packed along the axis of the cigarette prevents the heat from propagating from the central heating sheet to the outer tobacco filler along the radial direction of the cigarette, the tobacco The central area of ​​the rod is fully heated, but the outer peripheral area away from the central heating sheet is not sufficiently heated, the heat utilization efficiency is low, and the overall heating of the tobacco rod is uneven

In addition, since the shredded tobacco fillers arranged in the axial direction are packed tightly and the heating sheet is inserted into the tobacco rod axially, the resistance is relatively large when the tobacco rod is inserted and pulled out, and the heating sheet is easy to break

[0006] 2. Granular tobacco type heat-not-burn products have low compatibility, and can only use their own pods, with small smoke volume and mild tobacco taste

Although patents have reported tobacco particle-type heat-not-burn cigarettes that look similar to traditional cigarettes (CN201811489706.3, CN201811487278.0, CN201811488351.6), they are mainly manufactured by adding granular tobacco fillers to paper empty tubes. Cigarettes, the particles are in a loose state in this type of non-rolling cigarettes. In order to prevent the particles from falling from the cigarettes, it is necessary to add a blocking device to the end (open end) of the cigarette away from the mouth rod to seal the particles. Increased the complexity of cigarette manufacturing and posed new challenges to the high temperature resistance, sealing and air permeability of the sealing device

The paper empty tube is made of multiple layers of paper, which has high hardness, poor air permeability and heat transfer efficiency

In addition, cigarettes cannot be manufactured through the rolling process because paper empty tubes are used to fill granules to manufacture cigarettes, and automatic cigarette manufacturing equipment cannot be used for assembly line operations to manufacture cigarettes
