Cut tobacco drying technology method adopting HDT to reduce phenol release amount of cigarettes

Abstract

The invention discloses a cut tobacco drying technology method adopting an HDT to reduce phenol release amount of cigarettes. The specific technological parameters are as follows: moisture content at a material inlet: 18%; and steam quantity: 850 kg / h. The cut tobacco drying technology method has the benefits that the key procedure, cut tobacco drying, in the cut tobacco manufacture technology is controlled, specific cut tobacco drying equipment, an HDT (overheat steam drying cut tobacco dryer) is selected and subjected to parameter combination adjustment under the premise that stable sensory quality of cigarettes is kept, so that the phenol release amount in main stream smoke of cigarettes is reduced, 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 phenol release amount of cigarettes is effectively reduced under the premise that stable sensory quality of cigarettes is kept.

Description

technical field [0001] The invention relates to a cigarette processing method for reducing phenol release, in particular, a shred drying process for reducing phenol release by using an HDT superheated steam drying shred dryer in the shred making process of cigarette processing. 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 development...

Problems solved by technology

Chinese patent ZL201010288186.7 discloses a cigarette processing method for reducing phenol content. 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 phenol 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 phenol released, the silk-drying section in the patent uses a drum sheet-type silk-drying machine, and does not limit other types of silk-drying equipment

[0008] 1. Various research institutes ignore the influence of specific drying equipment process parameters on the release of phenol;

[0009] 2. The impact of different drying equipment on the release of phenol in cigarette smoke 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. 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;
