Cut tobacco drying processing method for reducing release amount and H value of harmful ingredients of cigarettes through HDT

Abstract

The invention discloses a cut tobacco drying processing method for reducing the release amount and the H value of harmful ingredients of cigarettes through an HDT. The harmful ingredients include ammonia, carbonic oxide and NNK in smoke of the cigarettes. The processing parameters are as follows: the moisture content of a material inlet is 24%; evaporation application amount is 850kg / h. The cut tobacco drying processing method has the advantages that by controlling the key point of the cut tobacco processing, namely, the cut tobacco drying process, under the premise of keeping sensory quality of the cigarettes to be stable, parameter combination adjustment is performed on a cut tobacco drying device to achieve the purposes of reducing the H value of the cigarettes and the release amount of the ammonia, the carbonic oxide and the NNK in mainstream smoke of the cigarettes; a new way for reducing harm and tar of the cigarettes is explored; therefore, the cut tobacco drying processing method has important theoretical significance and practical application value. According to the cut tobacco drying processing method, key parameters in the cut tobacco drying process are screened, affirmed and optimized within the production processing range, and the H value of the cigarettes and the release amount of the ammonia, the carbonic oxide and the NNK in the smoke of the cigarettes are effectively reduced under the premise of ensuring the sensory quality of the cigarettes to be stable.

Description

technical field [0001] The invention belongs to the field of cigarette harm reduction, and relates to a cigarette processing method that simultaneously reduces the H value of cigarettes, reduces the release of ammonia, reduces the release of carbon monoxide, and reduces the release of NNK. Superheated steam drying silk drying machine is a silk drying process that reduces H value, ammonia release, carbon monoxide release and NNK release. Background technique [0002] The two guidelines of "prevention of exposure to tobacco smoke" and "control and disclosure of tobacco ingredients" in the "Framework Convention on Tobacco Control" require governments to formulate more stringent "tobacco control" laws and regulations, urging cigarette manufacturers to reduce cigarette tar emissions At the same time, it is necessary to strictly control the release of the main harmful components in cigarette smoke, further increasing the pressure on the industry to reduce harm and reduce coke.

In order to achieve the goal of optimizing the parameters of the entire silk-making process and reducing the amount of ammonia released, the silk-drying section in the patent uses a drum thin-plate type silk drying machine, and does not limit other types of silk drying equipment

Chinese patent ZL201010288102.X discloses a cigarette processing method for reducing carbon monoxide content. The process parameters are optimized from the three processes of microwave loosening, loosening and moisture recovery, and HT+shred drying, all of which achieve the purpose of reducing the amount of carbon monoxide released in cigarette smoke. In order to achieve the goal of optimizing the parameters of the entire silk-making process and reducing the amount of carbon monoxide released, the silk-drying section in the patent uses a drum-type silk-drying machine, and does not limit other types of silk-drying equipment

Chinese patent ZL201010288153.2 discloses a cigarette processing method for reducing NNK content. The process parameters are optimized from the three processes of microwave loosening, loosening and regaining moisture, and HT+shred drying, all of which achieve the purpose of reducing the amount of NNK released in cigarette smoke. In order to achieve the goal of optimizing the parameters of the entire silk-making process and reducing the release of NNK, the drying section in the patent uses a drum thin-plate type silk drying machine, and does not limit other types of silk drying equipment

[0015] 1. Various research institutes ignored the influence of specific drying equipment process parameters on the H value of cigarettes and the release of ammonia, carbon monoxide and NNK in smoke;

[0016] 2. The influence of different drying equipment on the H value of cigarettes and the release of ammonia, carbon monoxide and NNK in cigarette smoke varies greatly;

[0017] 3. Due to the particularity of tobacco products, there are strict requirements on the moisture at the outlet of dried silk, generally 12%±0.5%. Under the premise of ensuring the safe operation of the equipment and product availability, only the combination parameters can be selected within the respective adjustable ranges. Control, and to determine a parameter combination requires a lot of research experiments;

[0018] 4. The cost of production test is high. Only 5-8 tons of raw materials are invested in one test, and the cost is more than 400,000. In addition, it is necessary to ensure that the product cannot become waste during the test process, which increases the difficulty of obtaining test data;
