Design and application of control strategy for moisture content in redried tobacco strips packed in cases
To study the rewetting characteristics of tobacco strips during the redrying stage, a conjugate heat and mass transfer model of tobacco strips was established based on their physical properties. The fundamental relationship between the multiphysical fields and humidity fields of tobacco strips and the key process parameters was considered in this model, and the feasibility of the model was verified via experiments. Based on this model, the transfer and variation laws of the moisture content, humidification rate, and temperature of tobacco strips under different relative humidity and tempera
Method for release inspection of cigarette capsules with bubble defects
Smoking article inspection systems configured to inspect smoking articles are provided. The systems may include imaging devices configured to capture images of an exterior of the smoking article and an analysis unit configured to analyze the images captured by the imaging devices. The analysis unit may execute an edge detection tool configured to determine a position of the smoking article based on an edge location of the smoking article and a defect detection tool configured to determine whether the smoking article is defective after the position of the smoking article is determined. The i
Simultaneous detection of four tobacco-infecting viruses by multiplex RT-PCR
Tobacco bushy top disease is a complex disease caused by mixed infection of Tobacco bushy top virus (TBTV), Tobacco vein distorting virus (TVDV), satellite RNA of TBTV (Sat-TBTV) and Tobacco vein distorting virus associate RNA (TVDVaRNA). A one-tube multiplex reverse transcription-PCR (RT-PCR) assay was developed for simultaneous detection of the four causal agents of the disease. Four pairs of specific primers based on the conserved regions of each of the four disease agents were used in the one-tube RT-PCR. The RT-PCR products consisted of fragments of 1049 base pairs (bp) for TBTV, 792bp
Design of accurate correlation system for QR code information of products of cigarette packing line
This study employs the EIQ analysis approach to quantitatively examine the real order data of the cigarette distribution center in an effort to further increase the efficiency of cigarette sorting and distribution. To further increase the accuracy and efficiency of sorting labor, a sorting system based on QR code information and an accurate identification algorithm is proposed with the use of statistical data and the associated planning scheme. According to the system simulation findings, the sorting efficiency of the system’s sorting line is 18570 pieces per hour. However, by adding pack
Threshing and redrying technology based on typical mechanical characteristics of tobacco leaves of cv.
The invention discloses a threshing and redrying method for reducing the stem content in strips and a stemming tool, belonging to the technical field of threshing and redrying of tobacco industry. The stemming of the tobacco leaves with the water content of 16 to 17 percent is carried out under the conditions of the environmental temperature of 18 to 25 DEG C and the humidity of 60 to 70 percent;the size of a frameset of a threshing machine unit is adjusted to a larger grade, the rotation speed of a threshing roller of the threshing machine unit is reduced by 5 to 10 percent, the rotation s
Determination of eight cooling agents in tobacco materials for heated tobacco products by gas chromatography-mass spectrometry
Glycerin and propylene glycol are the main components of the atomizing agent in heat-not-burn tobacco products (HnB), which affect the smoke release of HnB significantly. In this study, the roles of the glycerin and propylene glycol as the atomizing agent on smoke release of HnB were studied by using a fixed-bed reactor system. The effects of glycerin to propylene glycol ratio in the atomizing agent, and the content of atomizing agent in the HnB were investigated. Gas chromatographymass spectrometer (GC-MS) was used to analyze the condensable components in the released smoke, and gas chroma
Determination of phenolic antioxidants in hotmelt adhesives for cigarette
The present paper describes the thermal oxidation of a mixture applied as hot melt adhesive and particularly of its essential polymeric component ethylene-propylene copolymer Licocene 2602 either virgin or grafted by acrylic acid. Chemiluminescence in oxygen under both nonisothermal and isothermal conditions was used as the tool for evaluation of oxidation stability of samples. The effect of various concentrations of stabiliser Naugard XL1 acting as a metal deactivator and phenolic antioxidant was also determined and the antioxidant selected was found to be an efficient thermooxidative stab
Weed species and community characteristics in central Henan tobacco fields
Bacterial wilt as a soil-borne disease was caused by Ralstonia solanacearum, and seriously damages the growth of tobacco. Integrated biocontrol method was explored to control bacterial wilt. Nevertheless, the long-term effects of the integrated biocontrol method on soil bacterial community, soil physicochemical properties and the incidence of bacterial wilt are not well understood. In this study, B. amyoliquefaciens ZM9, calcium cyanamide and rice bran were applied to tobacco fields in different ways. The disease index and incidence of tobacco bacterial wilt (TBW), soil physicochemical prop
Research progress on drought resistance genes in tobacco
Drought causes not only the decrease of tobacco yield and quality, but also the lowering of net photosynthetic rate, leading to reactive oxygen species accumulation and even the death of plants. Salicylic Acid is involved in regulating many plant physiological processes and has increasingly been applied to improve tolerance in plants exposed to drought stress. To explore the regulating mechanism of SA, flue-cured tobacco K326 was used in the hydroponic experiments to design PEG drought stress. The photosynthetic characteristics, antioxidant enzymes activities and osmotic regulatory substanc
Effects of cigarette circumference and filter ventilation rate on releases of alkaline aroma components in mainstream cigarette smoke
In order to study the effect of circumference and filter ventilation rate on the release of alkaline flavor components in cigarette mainstream smoke, CH2Cl2 extraction and GC/MS analysis were used to measure the mainstream smoke of cigarette samples with different circumference and filter ventilation. The release amount of 21 kinds of basic flavor components in tobacco. The results showed that: The various basic flavor components and the total amount of basic flavor components released per gram of shredded tobacco showed an increasing trend with the increase of the circumference of the ciga
