Cut tobacco drying technology method adopting SH94 to reduce NNK release amount of cigarettes

Abstract

The invention discloses a cut tobacco drying technology method adopting an SH94 to reduce NNK release amount of cigarettes. The specific technological parameters are as follows: moisture content at a material inlet: 26.15%; and steam quantity: 801 kg / h. The cut tobacco drying technology method has the benefits that the cut tobacco drying procedure is controlled to combine and adjust technological parameters and further reduce the NNK release amount in main stream smoke of cigarettes, a new path to reduce coke of cigarettes is explored, and the method is of vital theoretical significance and practical application value; and key parameters in the cut tobacco drying procedure are selected, confirmed and optimized in the production technology range, so that the NNK release amount in main stream smoke of cigarettes is effectively reduced under the premise that stable sensory quality of cigarettes is kept.

Description

technical field [0001] The invention belongs to the field of cigarette harm reduction, and relates to a method for reducing the NNK release of cigarettes, in particular to a cigarette processing method for reducing the NNK release of cigarettes by adjusting shred drying process parameters. 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. Smoking and health are the main challenges facing the tobacco industry, and reducing harm and coke is related to the survival of the tobacco industry And...

Problems solved by technology

Chinese patent Z L201010288153.2 discloses a cigarette processing method for reducing the NNK 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 release of NNK in cigarette smoke. , so as to achieve the goal of optimizing the entire silk-making process parameters and reducing the release of NNK. In the patent, the silk-drying section uses KLD silk-drying equipment, and does not limit other types of silk-drying equipment

[0008] 1. Various research institutes have ignored the influence of specific drying equipment process parameters on the release of NNK;

[0009] 2. The influence of different drying equipment on the release of NNK in the smoke of cigarette products varies greatly;

[0010] 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%. On 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;

[0011] 4. The cost of production test is high, 5-8 tons of raw materials are invested in a test, and the cost is more than 400,000, and it is necessary to ensure that the product cannot become waste during the test process, which increases the difficulty of obtaining test data;
