Abstract

The invention discloses a cigarette heat treatment process quality analysis device, which comprises a gas sensor (1), a heater (2), a dehumidifier (3), a data acquisition memory (4) and a display (5),wherein the dehumidifier (3) is located at an inlet of the gas sensor (1), the heater (2), the dehumidifier (3) and the gas sensor (1) are packaged in a detection chamber (6), and the detection chamber (6) is in gas communication with a gas inlet pipeline (7); and the data acquisition memory (4) is respectively connected with the gas sensor (1) and the display (5). The analysis device disclosed by the invention is used for detecting volatile chemical substances emitted by tobacco subjected to hot processing; the influence of the tobacco heat treatment process on the intrinsic quality of tobacco is directly concerned, the problem of real-time monitoring of tobacco volatile chemical substances in the heat treatment process is effectively solved, and comprehensive, objective and scientific judgment of the process quality is achieved through monitoring of the volatile chemical substances.

Description

technical field [0001] The invention belongs to the application field of the tobacco industry, and in particular relates to a quality analysis device and analysis method for a cigarette heat treatment process. Background technique [0002] During the cigarette processing process, the tobacco undergoes a series of treatments such as heating, humidification, and drying, so that it is placed in an environment where the temperature and humidity are constantly changing, which will inevitably lead to a series of changes in the chemical substances inside the tobacco. Some volatile chemicals Substances will gradually volatilize when the temperature changes. As far as cigarette processing is concerned, the previous research objects mainly focused on the tobacco itself after various processes, and less attention was paid to some substances that have volatilized during the processing process. After the tobacco is processed, some substances have been volatilized during the processing pr...

Problems solved by technology

[0002] During the cigarette processing process, the tobacco undergoes a series of treatments such as heating, humidification, and drying, so that it is placed in an environment where the temperature and humidity are constantly changing, which will inevitably lead to a series of changes in the chemical substances inside the tobacco. Some volatile chemicals Substances will gradually volatilize when the temperature changes. As far as cigarette processing is concerned, the previous research objects mainly focused on the tobacco itself after various processes, and less attention was paid to some substances that have volatilized during the processing process. After the tobacco is processed, some substances have been volatilized during the processing process, and the volatilized components contain many aroma-causing substances, mainly including aromatics, Maillard reaction products, cebradane-like degradation products and carotenoids Degradation products and other chemical substances, the excessive loss of such substances will have a great impact on the overall quality of cigarette products. Due to the complexity of the tobacco matrix, online monitoring of such substances is very difficult, and related methods have not been reported

[0003] At present, the main indicators for judging the quality of the cigarette processing process are the moisture and temperature of the tobacco. This kind of judging method is relatively intuitive and easy to detect, but it is too simple. The standard requirements have been met, but due to the differences in the grade, location and origin of the tobacco itself, the volatile aroma-generating substances in the tobacco have been excessively volatilized due to excessive processing intensity, which undoubtedly affects the quality of cigarette products

Only pay attention to the physical indicators after tobacco processing, but ignore the changes of chemical substances in the tobacco processing process, which cannot comprehensively, objectively and scientifically reflect the quality of process processing, let alone set parameters for each process and make the parameters between processes reasonable Matching provides scientific basis

However, the existing sensor application fields are mainly concentrated in routine detection, which cannot be well adapted to the high-temperature and high-humidity environment of the cigarette heat treatment process.
