Problems solved by technology

[0006] The factors affecting the test of cigarette tar can be divided into two blocks: one is the tunnel block. A large number of experiments have shown that under specified conditions (although it is a specified condition, there will be a certain change within the specified range) multiple tunnels simultaneously carry out the same test. In the cigarette tar test, the total particulate matter, nicotine, moisture and final tar amount measured by different channels are quite different, which is mainly due to the suction capacity of each suction channel of the smoking machine, the environment The air velocity and some other factors are not exactly the same, resulting in incomplete suction; the second is the time block, the total particulate matter, nicotine, moisture and the final volume measured at different times in the same channel under specified conditions. There is a big difference in the amount of tar, which is mainly due to the time-varying atmospheric temperature, atmospheric humidity, air velocity and other factors that change with time, which have a certain impact on the combustion of cigarettes, thus affecting the test of cigarette tar

[0061] Formulation of 3-treatment suction scheme for 20-hole smoking machine

[0062] The number of holes in the smoking machine is 20, the number of cigarettes to be processed is 3, 20 divided by 3 equals 6 and 2, rounded down to 6, 3×6=18, only the first 18 holes are used to formulate the smoking plan. Cigarettes with 3 treatments in each puff, each treatment occupying 6 holes.

[0063] During the first puff, cigarettes with the first treatment are placed in holes 1-6, cigarettes with the second treatment are set in holes 7-12, and cigarettes with the third treatment are set in holes 13-18; , cigarettes with the second treatment in 1-6 holes (the treatment number of cigarettes with the first b holes is equal to the number of puffs), cigarettes with the third treatment in 7-12 holes (the number of cigarettes with the next b holes is equal to the number of puffs), Add 1 to the number of treatments set for the first b tunnels), and set the cigarettes of the first treatment in ...

[0066] Comparative Analysis of Tar Tests on Three Kinds of Treated Cigarettes Using a 10-hole Smoking Machine

[0067] ① Selected smoking plan and cigarette smoking

[0068] There are 3 kinds of cigarettes processed by different processes, according to figure 1 Cigarette smoking is carried out according to the scheme, and each hole continuously sucks 4 cigarettes of the same treatment in each puff (every 4 cigarettes share a filter filter); in each puff, each treatment cigarette Occupying 3 holes, 12 cigarettes were smoked for each treatment; 9 holes were shared, and a total of 36 cigarettes were smoked in each smoking experiment. After smoking according to the selected scheme, the total particulate matter of cigarettes with different puffing times, different holes and different treatments is obtained. The nicotine and moisture of cigarettes with different puffing times, different holes and different treatments are measured, and the different puffing times and different hole...

[0126] Comparative analysis of tar test on five processed cigarettes using a 20-hole smoking machine

[0127] In order to study the effectiveness of cigarette coke reducers, different amounts of coke reducers were added to the same kind of cigarettes. , the newly made cigarettes are referred to as the first treated cigarettes, the second treated cigarettes, the third treated cigarettes, the fourth treated cigarettes, and the fifth treated cigarettes. according to Figure 6 Cigarette smoking is carried out according to the scheme, in each puff, 4 cigarettes of the same treatment are continuously sucked in each puff, and the total particulate matter of cigarettes with different puff times, different puffs and different treatments are obtained after smoking, and the different puffs are measured. The nicotine and moisture of cigarettes with different puffs and different treatments in the number of puffs can be used to obtain the tar content of cigarettes with different puffs and ...

Abstract

The invention relates to a method for testing tar amount of cigarettes treated differently. The method comprises a space and time distributed three-factor and two-block suction scheme and a cigarette suction and gas chromatography, and also comprises a significance examination and repetition of suction scheme. According to the invention, each tunnel is equipped with a same number of treated cigarettes which are all balanced on a tunnel block. Variations caused by different tunnels will influence each variety of treated cigarettes equally, so that influences by a tunnel block factor can be deducted. A same number of each variety of treated cigarettes is in each suction, and a suction frequency expresses a block on a time basis; so the cigarettes are balanced on the time block. Thereby, influences by a time block factor can be deducted. In addition, a test result is more reasonable and accurate.

Description

technical field [0001] The invention relates to a method for testing the tar content of cigarettes with multiple treatments, in particular to a method for comparing and analyzing the tar content by smoking cigarettes with multiple treatments with a multi-channel smoking machine. Background technique [0002] When a cigarette is burned, it will produce smoke (when smoking, the aerosol drawn into the mouth through the filter is the smoke), and the smoke of the cigarette is composed of two parts: the gas phase substance and the particle phase substance (also often referred to as the total particle phase substance) Among them, the part of the flue gas that can pass through the Cambridge filter (a glass fiber filter) at room temperature is called the gas phase substance; the part of the flue gas that is intercepted is called the particle phase substance, which contains moisture, smoke Alkali and tar. Tar is the total particle phase after deducting water and nicotine. [0003] C...
