   Processing method for heating non-burning cigarette    [Cross Reference Related Applications]

This application claims priority from a Chinese patent application filed on June 19, 2017 with application number 2017104626338, entitled "A Processing Method for Heating Non-Combustion Cigarettes", the entire contents of which are incorporated herein by reference. in.

The present invention relates to the technical field of heating non-combustion cigarettes, and in particular, to a processing method for heating non-combustion cigarettes.

In traditional cigarettes, there are dozens of carcinogens in the smoke produced by the burning of tobacco. Relevant research shows that the generation of various chemical substances in smoke is closely related to the level of cigarette burning temperature. The harmfulness index of cigarettes increases with the increase of cigarette burning temperature. At the same time, smoke fills the air to form second-hand smoke. Heating non-combustion cigarettes is a new type of cigarette system. It produces smoke by baking low-temperature 200-400 degrees of solid smoking materials such as cut tobacco. The cut tobacco does not burn. Because the baking temperature is lower than the burning temperature, the harmfulness can be greatly reduced. The production of substances is of great significance in the international environment and background of smoking and tobacco control.

In the well-known traditional cigarettes, the tobacco is smoked by ignition, and the non-combustion cigarettes are heated and not burned. Due to the low curing temperature, the effective components in the shredded tobacco are difficult to volatilize, and the volatilized effective components are easily adsorbed by the shredded tobacco again, resulting in smoking. Poor suction quality and low smoke volume.

Tobacco is composed of leaf shreds, stalk shreds, expanded shreds, and the like. The inventors found that the effective ingredients in the shreds are difficult to volatilize because the shreds are of different lengths and in a disordered and disordered manner, and there is no regular arrangement. In view of this, the present invention provides a processing method for heating non-combustion cigarettes, which better overcomes the problems and defects of the foregoing prior art. By orderly arranging the shreds, the shreds also form an orderly space between the shreds. Compared with the disorderly arrangement of shredded tobacco, the porosity is greatly improved, which ensures good ventilation and consistency of airflow inside the cigarette; the orderly arranged shredded tobacco and the orderly arranged voids provide an approximately straight line for the flow of smoke. The air flow channel reduces the resistance of suction and the tobacco adsorption performance to the smoke, and improves the passing efficiency of the smoke.

A processing method for heating non-combustion cigarettes, comprising: cutting sheet-shaped reconstituted tobacco leaves into a plurality of long shreds in one direction; squeezing a plurality of said long shreds together in a width direction of said long shreds, and A cylindrical tobacco rod is wrapped by forming paper, and a plurality of the long tobacco shreds in the tobacco rod are arranged regularly and orderly.

Further, the reconstituted tobacco leaf is one of the reconstituted tobacco leaf made by papermaking, the reconstituted tobacco leaf made by dry method, the reconstituted tobacco leaf made by thick pulp method, and the reconstituted tobacco leaf by roll method.

Further, the length of the reconstituted tobacco leaf is not less than 10.0mm, and the width of the reconstituted tobacco leaf is not less than 20.0mm.

Further, the quantitative index of absolute dryness of the reconstituted tobacco leaf is 20 to 110 g / m ² ; and the thickness of the reconstituted tobacco leaf is 0.05 to 0.60 mm.

Further, the length of each of the long cut tobacco is not less than 10.0 mm, and the width of each of the long cut tobacco is 0.5 to 3.0 mm.

Further, a plurality of the long cut tobacco is squeezed together in a width direction of the long cut tobacco by using a cigarette rolling machine or a filter rod forming machine.

Further, the surface of the forming paper is coated with a flame retardant.

Further, the flame retardant is a mixture of one or two of magnesium hydroxide and aluminum hydroxide.

Further, the surface of the forming paper is coated with an atomizing agent.

Further, the atomizing agent is a mixture of one or more of propylene glycol, glycerol, propylene glycol acetate, and glyceryl acetate.

Compared with the prior art, the beneficial effects of a method for processing a non-burning cigarette according to the present invention are as follows.

The processing method for heating non-combustion cigarettes of the present invention comprises cutting reconstituted tobacco leaves into multiple long shreds in one direction, and cutting the multiple long shreds along a long shred using a device such as a cigarette splicer or a filter rod forming machine. Squeeze in the width direction to form an orderly arrangement of cut tobacco rods. The cut tobacco rods are wrapped by forming paper to form a cylindrical arrangement of cut tobacco rods. An orderly arrangement of voids is also formed between the cut tobacco rods. Tobacco shreds greatly improve the porosity and ensure the good ventilation and consistency of airflow inside the cigarette. On the one hand, the air can pass through the forming paper from the periphery of the cigarette to enter the inside of the cigarette during the suction, which provides air for the generation of smoke. Support; more importantly, in the longitudinal direction of the cigarette, the orderly arranged shredded tobacco and the orderly arranged gaps provide an approximately straight airflow channel for the smoke flow, reducing the resistance to suction and the shredded tobacco. The adsorption performance of the flue gas improves the passing efficiency of the flue gas, thereby improving the suction quality, and effectively solving the technical problems of low-temperature flue gas with a small amount of smoke and poor suction quality.
