Cut tobacco drying technology method adopting HDT to reduce H value of cigarettes

Abstract

The invention discloses a cut tobacco drying technology method adopting an HDT to reduce H value of cigarettes. The specific technological parameters are as follows: moisture content at a material inlet: 24%; 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, the H value 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 H value 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 shredded cigarette drying process method for reducing the H value of cigarettes, in particular, a shredded shredded drying method for reducing the H value of cigarettes by using an HDT superheated steam drying shredded machine in the shredded process of cigarette processing craft. Background technique [0002] It has been unanimously recognized by all walks of life that smoking is harmful to health. With the impetus of the World Health Organization, governments of many countries and various anti-smoking groups, the global anti-smoking movement is increasing day by day, and the social pressure on the tobacco industry is increasing. The "Framework Convention on Tobacco Control" signed by the Chinese government stipulates that the Chinese government should formulate more stringent "tobacco control" laws and regulations, urging cigarette manufacturers to strictly control the m...

Problems solved by technology

Chinese patent ZL201010288196.0 discloses a cigarette processing method that reduces the H value. The process parameters are optimized from the three processes of microwave loosening, loosening and moisture regain, and HT+shred drying, all of which achieve the purpose of reducing the H value of cigarettes, thereby achieving the optimization of the entire cigarette. For the purpose of reducing the H value due to the parameters of the silk making process, 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

[0017] 1. Various research institutions ignore the influence of specific drying equipment process parameters on H value;

[0018] 2. The influence of different drying equipment on the H value of cigarettes varies greatly;

[0019] 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;

[0020] 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;
