Method and device for rapidly and objectively distinguishing real and counterfeit cigarettes

Abstract

The invention discloses a method and a device for rapidly and objectively distinguishing real and counterfeit cigarettes. The method comprises the following steps: acquiring a weightlessness curve of a to-be-detected cigarette through thermogravimetric analysis; inquiring a standard weightlessness curve related to the to-be-detected cigarette; acquiring the similarity of the to-be-detected cigarette according to the weightlessness curve of the to-be-detected cigarette and the standard weightlessness curve; judging whether the similarity of the to-be-detected cigarette is greater than a predetermined threshold value; judging the to-be-detected cigarette to be a counterfeit cigarette if the similarity of the to-be-detected cigarette is greater than the threshold value; judging the to-be-detected cigarette to be a real cigarette if the similarity of the to-be-detected cigarette is lower than or equal to the threshold value. According to the invention, real and counterfeit cigarettes are identified through thermogravimetric analysis, the cigarettes are not needed to be subjected to complicated pretreatment, no chemical agent is used, so that the system error and the personal error are greatly reduced, the automatic sample feeding can be realized, a large quantity of samples can be analyzed, and the efficiency of analysis and detection is greatly improved.

Description

technical field [0001] The invention relates to the field of cigarette detection, in particular to a method and device for quickly and objectively distinguishing genuine and fake cigarettes. Background technique [0002] As an illegal commodity, the most basic feature of counterfeit cigarettes is to use various methods to counterfeit well-known and best-selling cigarettes of various brands that have been sold in the market. This not only interferes with the order of the national tobacco monopoly market, but also seriously damages the the interests and health of consumers. [0003] At present, the identification of real and fake cigarettes is mainly based on people's various senses, such as comparing the packaging differences of real and fake cigarettes through visual observation, such as box label printing, pulling lines, sealing, sealing, etc., and also through taste The real and fake cigarettes are judged and smoked by the sense of smell and smell, but such sensory evalua...

Problems solved by technology

However, the research objects of the prior art are all the tobacco used in cigarettes, and as a commodity, cigarettes can meet consumer demand not the tobacco itself, but the flue gas produced after tobacco pyrolysis and combustion. Tobacco's own detection method is less accurate and less efficient
