A method of drying shreds by using a roller tube plate shred dryer to reduce the release of bap from cigarettes

Abstract

The invention discloses a cut tobacco drying technology method adopting a roller pipe sheet type cut tobacco dryer to reduce BaP (benzopyrene) release amount of cigarettes. The specific technological parameters are as follows: moisture content of incoming material at an HT inlet: 19.3%; steam pressure of HT: 0.1 MPa; hot air temperature: 70 DEG C; opening degree of a hot air ventilation door and opening degree of a damp-proof ventilation door: 39.9% and 30% respectively; and rotating speed of a cut tobacco drying cylinder: 13 rmp. 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 BaP release amount 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 BaP 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 emission of BaP (benzo[a]pyrene) from cigarettes, in particular to a method for reducing the emission of benzo[a]pyrene from cigarettes by adjusting the process parameters of shred drying equipment Methods. Background technique [0002] <<Framework Convention on Tobacco Control>> stipulates that the governments of various countries should formulate strict "tobacco control" laws and regulations, urging cigarette manufacturers to strictly control the release of major harmful components in cigarette smoke while reducing the amount of tar released from cigarettes . 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 leaf raw materials, cigarette processing technology and auxiliary material design on the releas...

AI Technical Summary

Problems solved by technology

[0005] 1. Various research institutes neglected the influence of specific drying equipment process parameters on the release of benzo[a]pyrene;

[0006] 2. The impact of different drying equipment on the release of benzo[a]pyrene in the smoke of cigarette products varies greatly;

[0007] 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;

[0008] 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;
