      • Potassium염이 궐련의 연기성분 이행량에 미치는 영향

        諸炳權,李鶴洙 충북대학교 엽연초연구소 1999 煙草硏究 Vol.17 No.-

        This study was conducted to evaluate the temperature decreasing of burning cone by adding the potassium salt to reconstituted tobacco sheet. To find effect of the potassium on the temperature, we examined the delivery smoke components and the distribution of aroma components effected tabacco taste by electronic nose system. The results are summarized as follows : 1.Burning cone temperature was decreased 100℃ that was identified by DTG curve. 2.When 3% potassium salt was added to reconstituted tobacco sheet, TPM, CO, tar, and nicotine in smoke delivery were lowed as 11%, 16%, 11%, and 16%, respectively and Co/tar ratio was decreased from 1.81 to 1.70. 3.By adding the potassium salt, carbonyl compounds in smoke, such as propionaldehyde and formaldehyde, were decreased as 17% and 5%, respectively And also acrolein, acetone and acetaldehyde were decreasing up to 9%. There was no change of phenolic compounds delivery. 4.Adding the potassium salt to reconstituted tobacco sheet is desirable for cigarette manufacture by no change of distribution and delivery of TPM and aroma which was the main factors of tobacco taste.

      • Measurement of the Apparent Density of Shred and Void Fraction in a Tobacco Column

        Oh, In-Hyeog,Jeh, Byong-Kwon,Ra, Do-Young,Kwak, Dae-Keun,Kim, Byeoung-Ku,Jo, Si-Hyung,Rhee, Moon-Soo The Korean Society of Tobacco Science 2007 한국연초학회지 Vol.29 No.1

        The measurement of physical properties such as apparent density and void fraction of tobacco materials, which is so bulky, is a main theme with regard to tobacco process, quality control, cigarette combustion and smoke generation. Except Solution Impregnation Method, there was no alternative method for measuring those properties in the porous material so far. However, experimental processes of that method are so complicated as to cost much time and labor, the main solution such as mercury to apply to the method is usually very hazard. Therefore, we had developed a new method to determine them easily in our other paper by the mathematical equations derived from the Ergun equation for the purpose of it, and then already evaluated our method through applying some basic data from Muramatsu et at. (1979) with regard to our developed equations. Then, we found our method best fit to experimental one (Oh et al., 2001). In this study we tried to establish our method to conveniently determine those physical properties. Especially, we have focused on the development the easy way to measure surface area and the volume of single shred in a tobacco column. As a result of that, we found that the computer image analyzer was best fit for it. Then, we have finally determined apparent density and void fraction for our domestic tobacco shred.

        Effects of Fiber Composition of Cigarette Papers on the Pyrolytic Chemicals of Cigarettes by Combusting Process

        Man-Seok Seo,Jong-Yeol Kim,Soo-Ho Kim,Byong-Kwon Jeh 한국펄프·종이공학회 2017 펄프.종이기술 Vol.49 No.3

        The fiber compositions of cigarette papers were considered to evaluate the effects of flax and wood fibers of cigarette papers on the pyrolytic chemicals of cigarettes. In the two different circumferential cigarette systems, the replacement of flax paper by wood paper was carried out to simulate the effects of flax and wood fibers. The pyrolytic chemicals of cigarettes such as tar, nicotine, and carbon monoxide (CO) were analyzed by combusting process. The replacement of papers from flax to wood fibers showed similar levels of tar and nicotine, but showed an increased delivery of CO. The pyrolytic amounts of CO were different, depending on the properties of flax and wood paper, and porous structure of paper.

      • 잎담배 및 제품담배의 재떨어짐에 관한 연구

        양범호,안대진,조시형,제병권,김시몽,김병구,Yang Burm-Ho,Ahn Dae-Jin,Jo Si-Hyung,Jeh Byong-Kwon,Kim Si-Mong,Kim Byeoung-Ku 한국연초학회 2004 한국연초학회지 Vol.26 No.2

        In this study, we have investigated the natural and puffing combustibility of cigarette brands and the compulsory ash-drop, and analysed factors related to the materials. Cigarette combustibility was greatly affected by the tobacco weight in cigarettes rod. Combustion rate of 4AOR cigarette made by flue-cured tobacco was 5.02 $^{mm}/_{min}\;and\;10\%$ faster than 1BO cigarette. Combustion pattern has interrelation with sugars, chlorine and ash contents among tobacco components. Combustion rate of 4DL, flue-cured tobacco was 55 seconds faster than 1CL tobacco extremely much in sugars contents, and ash drop was maintained at $21\%$ longer. Combustion time and burning rate were fast in cigarette made by expanded tobacco slice and tobacco stem and the formation of ash was poor. The length of puffed ash drop of expanded tobacco slice and tobacco stem were 18.6 mm and 25.2 mm and these forced ash drop length were 3.8 mm and 4.9 mm respectively. Puffed burning rate of general cigarette was $14.3\%$ faster than static burning rate and super slim type cigarettes was $21.3\%$ faster. Combustion rate and ash drop of domestic and foreign cigarette brands were quite different depending on tar level and cigarette types. The lower tar level, the faster combustion rate and the shorter ash drop.

        Near InfraRed Spectroscopy(NIRS) is a quick and accurate analytical method to measure multiple components in tobacco manufacturing process. This study was carried out to develop calibration equation of near infrared spectroscopy for the prediction of the amount of chemical components and hot water solubles(HWS) of reconstituted tobacco leaf. Calibration samples of reconstituted tobacco leaf were collected from every lot produced during one year. The calibration equation was formulated as modified partial least square regression method (MPLS) by analyzing laboratory actual values and mathematically pre-treated spectra. The accuracy of the acquired equation was confirmed with the standard error of prediction(SEP) of chemical components in reconstituted tobacco leaf samples, indicated as coefficient of determination($R^2$) and prediction error of sample unacquainted, followed by the verification of model equation of laboratory actual values and these predicted results. As a result of monitoring, the standard error of prediction(SEP) were 0.25 % for total sugar, 0.03 % for nicotine, 0.03 % for chlorine, 0.16 % for nitrate, and 0.38 % for hot water solubles. The coefficient of determination($R^2$) were 0.98 for total sugar, 0.97 for nicotine, 0.96 for chlorine, 0.98 for nitrate and 0.92 for hot water solubles. Therefore, the NIRS calibration equation can be applicable and reliable for determination of chemical components of reconstituted tobacco leaf, and NIRS analytical method could be used as a rapid and accurate quality control method.

        성용주,한영림,백신,김시몽,제병권,오인혁,이창국,김수호,신창호,김근수,Sung, Yong-Joo,Han, Young-Lim,Baek, Shin,Kim, Shi-Mong,Jeh, Byong-Kwon,Oh, In-Hyeog,Lee, Chang-Kook,Kim, Soo-Ho,Shin, Chang-Ho,Kim, Kun-Soo 한국연초학회 2008 한국연초학회지 Vol.30 No.2

        The application of RECON(Reconstituted tobacco sheet) and the ventilation technology has been considered as very useful methods for controlling the tar and nicotine deliveries in modern blended tobacco. In this study, the effects of RECON contents in simulated blends on the smoke delivery and burning temperature were evaluated in three different ventilation levels. The ventilation showed a great influence on the burning temperature and smoke deliveries. The nicotine, tar and CO deliveries was greatly reduced by the ventilation. The amount of RECON showed the minor impacts on the smoke delivery. In high ventilation level such as 85 % ventilation, there was no distinct change in smoke deliveries by the amount of RECON.
