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

Abstract

The invention discloses a cut tobacco drying technology method adopting an HDT to reduce hydrocyanic acid release amount of cigarettes. The specific technological parameters are as follows: moisture content at a material inlet: 24%; and steam quantity: 100 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 hydrocyanic acid 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 hydrocyanic acid 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 shred drying process method for reducing the release of hydrocyanic acid in mainstream smoke of cigarettes, specifically, in the shred making process of cigarette processing, an HDT superheated steam drying shred drying machine is used to reduce the release of hydrocyanic acid in mainstream smoke of cigarettes A kind of silk drying process. Background technique [0002] 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 main substances in cigarette smoke while reducing the amount of tar released from cigarettes. release of harmful components. In order to improve the quality and safety of cigarette products in my country, the State Tobacco Monopoly Administration clearly proposed that the research on the influence of tobacco ...

AI Technical Summary

Problems solved by technology

Chinese patent ZL201010288108.7 proposes a cigarette processing method for reducing HCN content, which optimizes the process parameters from the three processes of microwave loosening, loosening and moisture recovery, and HT + silk drying, all of which can reduce the release of hydrogen cyanide in cigarette smoke In order to achieve the goal of optimizing the parameters of the entire silk-making process and reducing the release of hydrocyanic acid, 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

[0006] 1. Various research institutions have ignored the influence of specific drying equipment process parameters on the release of hydrocyanic acid;

[0007] 2. The influence of different drying equipment on the release of hydrocyanic acid in the smoke of cigarette products varies greatly;

[0008] 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 equipment and product availability, only the combined parameters can be selected within the respective adjustable ranges. Control, and to determine a parameter combination requires a lot of research experiments;

[0009] 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;
