Description
Technical Field
The invention belongs to the technical field of cigarette production by heating and non-combustion. More particularly, the present invention relates to a method of testing a tobacco rod containing an induction heating material.
Background
The heating non-combustion cigarette is a novel smoking mode at present, and provides tobacco characteristic aroma and nicotine in the cigarette for a smoker mainly in a mode of heating the non-combustion cigarette so as to meet the smoking requirement of the smoker. Compared with the traditional cigarette, the cigarette which is not burnt by heating can effectively reduce the harm to smokers and the harm to the environment, and effectively improves the safety. The heating methods adopted by the existing heating non-combustible tobacco products include resistance heating, electromagnetic heating, photon heating, chemical heating, carbon heating and the like. The principle of electromagnetic induction heating is that alternating current generated by an induction heating power supply generates an alternating magnetic field through an inductor (namely a coil), a magnetic conductive object is arranged in the alternating magnetic field to cut alternating magnetic lines, so that alternating current (namely eddy current) is generated inside the object, the eddy current enables atoms inside the object to randomly move at high speed, and the atoms collide with each other and rub to generate heat energy, thereby achieving the effect of heating the object. The electromagnetic heating technology has the advantages of high heating speed, high thermal efficiency, easy control of heating temperature, easy realization of automation of the heating process and the like.
The non-burning cigarette matched with electromagnetic heater is one kind of cigarette with mixed induction heating material and is prepared through adding stainless steel or similar metal material into tobacco shred in certain proportion, mixing and rolling. Whether the cigarette contains the induction heating material and whether the content of the induction heating material meets the design requirement is an important index for whether the cigarette can achieve the heating effect. In order to ensure that each cigarette contains qualified induction heating materials during production, a rejection link needs to be set for unqualified products so as to improve the quality of the products. But after rolling, the induction heating material in the cigarette can not be seen by naked eyes. At present, a method for detecting the content of induction heating materials in cigarettes is a manual screening method, particularly, the cigarettes are judged by tearing the cigarettes through manpower, the method wastes labor and cigarettes, and the efficiency is very low.
Therefore, an automated method for inspecting induction heating material in cigarettes is needed.
