Description

Technical Field

[0001] This invention relates to the field of tobacco product quality testing, and in particular to a rapid detection system and method for aroma concentration in flavor-enhancing cigarettes. Background Technology

[0002] In the production of flavored cigarettes, flavorings are typically applied to the filter rod tow. However, during filter rod processing and subsequent cigarette combustion, environmental changes and the precision of flavoring control can lead to inconsistent aroma concentrations reaching the consumer's mouth, severely impacting the stability of the product's sensory experience. Therefore, rapid and accurate aroma concentration consistency testing of the filter rods and finished cigarettes before and after production is crucial.

[0003] Currently, detection in this field mainly relies on gas chromatography-mass spectrometry (GC-MS). While this method offers high precision, it suffers from significant drawbacks, including complex sample pretreatment, long detection cycles (typically 2-4 hours per sample), high operational expertise, and expensive equipment. These limitations prevent it from meeting the demands of rapid batch screening and real-time quality monitoring on production lines. Electronic nose technology, while offering rapid response, suffers from insufficient quantitative accuracy and high equipment costs, making it unsuitable for precise quantitative quality control. Although photoionization detectors (PIDs) offer advantages such as rapid response, high sensitivity, and good quantitative performance for volatile organic compounds, their application in solid tobacco sample detection fails to ensure the stable, controllable, and repeatable release of aroma compounds to form a uniform detection gas. This results in poor reproducibility of aroma detection results, failing to accurately reflect the user's sensory experience and hindering the full realization of the rapid quantitative detection advantages of PID equipment. Summary of the Invention

[0004] This invention provides a rapid detection system and method for aroma concentration in flavor-enhancing cigarettes, overcoming the shortcomings of existing aroma detection technologies, such as slow speed, high cost, inability to simulate real smoking conditions, and inability to perform standardized quantitative detection.

[0005] A first aspect of this invention provides a rapid detection system for the aroma concentration of flavor-enhancing cigarettes, comprising a carrier gas supply module, an aroma sampling module, and a gas detection module connected sequentially along a gas path. The carrier gas supply module is used to adjust the first preset parameter value to provide the target clean carrier gas; The aroma sampling module is used to drive the target clean carrier gas to flow through the sample to be tested at a second preset parameter value, so as to simulate the human inhalation mode and form an aroma carrier gas. The gas detection module is used to detect the concentration of the target aroma substance in the aroma carrier gas; The first preset parameter value includes the temperature and humidity of the target clean carrier gas, and the second preset parameter value includes the flow rate and / or volume of the target clean carrier gas.

[0006] In a further embodiment, the carrier gas supply module includes a gas source, a gas purification unit, and a temperature and humidity control unit. The gas source is used to generate the initial carrier gas; The gas purification unit is used to purify the initial carrier gas; The temperature and humidity control unit is used to adjust the current temperature and humidity of the clean carrier gas to the target value.

[0007] In a further embodiment, the aroma sampling module and the gas detection module form a closed-loop detection system or a unidirectional detection system.

[0008] In a further embodiment, the aroma sampling module includes a piston-type suction device connected to it and a sampling chamber for containing the sample to be tested, wherein the sampling chamber receives the target clean carrier gas through a carrier gas inlet; The piston-type suction device is used to extract the target clean carrier gas in the sampling chamber with the second preset parameter value, and to make the extracted target clean carrier gas flow through the sample to be tested to generate aroma carrier gas and collect it in the sampling chamber. The sampling chamber is connected to the air inlet of the gas detection module via an aroma outlet, and the air outlet of the gas detection module is connected to the aroma inlet of the sampling chamber, so as to drive the aroma-carrying gas to circulate between the sampling chamber and the gas detection module.

[0009] In a further embodiment, the aroma sampling module includes a sample carrying cavity for accommodating the sample to be tested and an aroma collection device in an initial empty state. The sample carrier cavity receives the target clean carrier gas through the first port and outputs the aroma carrier gas to the aroma collection device through the second port. The outlet port of the aroma collection device is connected to the gas detection module, and the aroma-carrying gas is discharged directly after the concentration is detected by the gas detection module.

[0010] In a further embodiment, the inner surface material of the aroma collecting device is an inert material with low adsorption of the target aroma substance.

[0011] In a further embodiment, the sample carrier cavity is a closed cavity with an axial airflow channel, and the airflow channel is axially aligned with and connected to the internal pores of the sample to be tested.

[0012] In a further embodiment, the gas detection module includes a control unit and a photoionization detector. The control unit connects the corresponding valves of the aroma sampling module and the gas detection module to control the flow path of the target clean carrier gas or aroma-carrying gas. The photoionization detector is used to detect the concentration of the target aroma substance in the aroma carrier gas.

[0013] A second aspect of this invention provides a rapid method for detecting the aroma concentration of flavor-enhancing cigarettes, comprising the following steps: Step 1: Place the sample to be tested into the aroma sampling module, control the opening and closing of the corresponding valve, and turn on the carrier gas supply module to introduce the target clean carrier gas with preset temperature and humidity into the aroma sampling module to pre-equilibrate the sample to be tested. Step 2: Simulate the human body suction mode, and use the target flow rate and / or target volume to control the target clean carrier gas flow through the sample to be tested, so that the sample to be tested releases aroma substances and forms aroma carrier gas; Step 3: Control the opening and closing of the corresponding valve again to control the aroma carrier gas to form a closed or non-closed gas path with the gas detection module, and generate the concentration value of the target aroma substance in the aroma carrier gas through the gas detection module. Step 4: Repeat steps 1-3, detect and record the concentration values ​​of multiple test samples in the same batch, and generate consistency assessment results.

[0014] In a further embodiment, the target humidity value of the target clean carrier gas is 50-70%, the target temperature value is 35-45℃, the target flow rate is 35-50ml / 2s, and the target volume is 1000-2000ml.

[0015] In a further embodiment, step 4 also includes the following steps: A continuous detection scheme is established by adjusting the target temperature, humidity, flow rate, and volume of the target clean carrier gas by preset ranges. Based on the continuous detection scheme, multiple concentration values ​​of the same sample are detected and recorded to generate a concentration change curve; By comparing the concentration change curves of multiple test samples from the same batch, a consistency assessment result is generated.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) Highly simulates real inhalation and has strong sensory correlation: By precisely controlling the temperature and humidity of the carrier gas and simulating the flow rate and volume of human inhalation, the release conditions of aroma components in the real inhalation process are restored to the greatest extent, so that the instrument detection results are highly correlated with the sensory experience of consumers.

[0017] (2) "Standardized gas generation and collection" has been realized: the complex aroma release process has been standardized into controllable physical parameters, which solves the problem of poor reproducibility of traditional pretreatment and provides a stable, uniform and reliable gaseous sample for rapid detectors.

[0018] (3) Fast and accurate detection: Utilizing the fast response and high sensitivity of the PID detector, combined with the efficient standardized sampling process of this invention, the complete detection cycle of a single sample can be shortened to within a few minutes, while ensuring the accuracy and reproducibility of the quantitative results, perfectly meeting the production quality control requirements.

[0019] (4) Outstanding cost-effectiveness: Compared with expensive GC-MS and electronic nose, this invention achieves rapid and accurate aroma consistency screening with relatively low hardware cost, has high operation threshold and detection efficiency, and has economic feasibility for large-scale promotion and application.

[0020] To make the above-mentioned objects, features and advantages of the invention more apparent and understandable, preferred embodiments of the invention are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0021] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0022] Figure 1 This is a schematic diagram of the structure of the rapid detection system for aroma-enhancing cigarette aroma concentration provided in Example 1; Figure 2 This is a flowchart illustrating the rapid detection method for aroma concentration in flavor-enhancing cigarettes provided in Example 2. Detailed Implementation

[0023] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described in this specification are merely for explaining the invention and are not intended to limit the invention.

[0024] Figure 1 This is a schematic diagram of the structure of the rapid detection system for aroma-enhancing cigarette aroma concentration provided in Example 1, as shown below. Figure 1 As shown, it includes a carrier gas supply module 100, an aroma sampling module 100, and a gas detection module 300 connected sequentially along the gas path. The carrier gas supply module 100 is used to adjust the first preset parameter value to provide the target clean carrier gas at the target temperature and humidity. The aroma sampling module 200 is used to drive the target clean carrier gas to flow through the sample to be tested at a second preset parameter value, such as the target flow rate or target volume corresponding to the human inhalation mode, and generate aroma-carrying gas. The sample to be tested includes the filter rod to be tested or the cigarette sample to be tested. The gas detection module 300 is used to detect the concentration of the target aroma substance in the aroma carrier gas.

[0025] The detection system provided in the above embodiments can highly simulate the real smoking environment by setting first preset parameter values ​​such as temperature and humidity, and second preset parameter values ​​such as single-puff flow rate and total smoking volume, and realize "standardized gas generation and collection". This provides stable, reliable, and sensorily correlated gaseous samples for rapid detectors such as PID, and enables efficient and accurate evaluation of the consistency of aroma concentration in flavor-enhancing cigarette products.

[0026] In a specific implementation, the carrier gas supply module 100 in one embodiment includes a gas source, a gas purification unit, and a temperature and humidity control unit. The gas source is used to generate the initial carrier gas; The gas purification unit is used to purify the initial carrier gas; The temperature and humidity control unit is used to adjust the current temperature and humidity of the clean carrier gas to the target values. For example, the temperature is set between 35-45°C and the relative humidity is set between 50-70%, thereby simulating the human body's inhalation environment.

[0027] In the specific implementation process, the aroma sampling module and the gas detection module can form a closed-loop detection system. That is, the aroma-carrying gas flows in a closed loop between the aroma sampling module and the gas detection module, and the gas detection module, such as a photoionization detector (PID), performs continuous real-time concentration detection until the reading stabilizes, thereby obtaining an accurate aroma concentration detection result.

[0028] Specifically, in a preferred embodiment, the aroma sampling module 200 includes a piston-type suction device connected to it and a sampling chamber for containing the sample to be tested. The sampling chamber includes a carrier gas inlet, an aroma outlet, and an aroma outlet. A first air inlet valve is provided in the pipeline corresponding to the carrier gas inlet, a second air inlet valve is provided in the pipeline corresponding to the aroma outlet, and an exhaust valve is provided in the pipeline corresponding to the aroma outlet.

[0029] The sampling chamber is equipped with a sample placement inlet, through which testing personnel place the sample to be tested into the sampling chamber. Simultaneously, the sampling chamber is connected to a carrier gas supply module 100 via a carrier gas inlet, thereby introducing a target clean carrier gas regulated by temperature and humidity. The piston-type suction device is connected to the sampling chamber to simulate a preset human suction mode, such as actively extracting a fixed volume of target clean carrier gas according to a second preset parameter value, and allowing this target clean carrier gas to flow through the sample to be tested, thereby carrying the aroma components released in the sample and forming an aroma-carrying gas in the sampling chamber. For example, the simulated single-port suction flow rate can be 35-50 ml / 2 seconds, and the total volume to be extracted is determined based on the number of tests, etc. For example, if 100 ml is needed for one PID test, and the number of tests is 10, then the suction volume should not be less than 1000 ml.

[0030] The sampling chamber is connected to the gas detection module 300, such as a photoionization detector, via the aroma outlet. After sampling, the corresponding valve is controlled to close the carrier gas inlet of the sampling chamber, connect the aroma outlet to the gas inlet of the gas detection module 300, and connect the aroma inlet of the sampling chamber to the gas outlet of the gas detection module 300. This forms a closed gas circulation detection loop between the sampling chamber and the gas detection module 300, facilitating the gas detection module 300 to detect the concentration of the target aroma substance in the stable aroma carrier gas within the sampling chamber.

[0031] For example, embodiments of the present invention also provide a method for rapid detection of aroma concentration using the above-described system, such as... Figure 2 As shown, it includes the following steps: Step 1: Place the sample to be tested into the sampling chamber and seal it. Open the first air inlet valve and turn on the carrier gas supply module to introduce the target clean carrier gas with a temperature and humidity of 35-45℃ and 50-70%RH into the sampling chamber to pre-equilibrate the sample to be tested. Step 2: Close the exhaust valve of the sampling chamber, start the piston suction device, and extract the carrier gas from the sampling chamber according to the flow rate curve of simulated human single-mouth suction (e.g., 35 ml / 2 seconds) and the total suction volume (1000-2000 ml). The carrier gas is then passed through the sample to be tested to form aroma carrier gas and enriched in the sampling chamber. Step 3: After the data collection is completed, switch the valves, that is, close the first inlet valve and open the second inlet valve and the exhaust valve to form a closed loop gas path between the sampling chamber and the gas detection module. Start the gas detection module and use the circulation pump to push the gas in the sampling chamber to circulate in the closed loop gas path for real-time concentration detection until the reading stabilizes. Step 4: Repeat steps 1-3, detect the concentration values ​​of multiple test samples in the same batch, record and compare them, and generate consistency assessment results.

[0032] Of course, in other embodiments, closed-loop detection systems with other structures or connection methods can also be used, all of which are within the protection scope of this invention and will not be described in detail here.

[0033] As those skilled in the art know, gases detected by photoionization detectors undergo physical or chemical processes, potentially resulting in new material changes. When these gases are recirculated through a closed-loop gas path back into the carrier gas of the aroma to be detected and participate in detection again, the accuracy of the detection data can be easily affected. To further improve detection accuracy, the aroma sampling module and gas detection module of this invention can also employ a unidirectional detection system, that is, directly discarding the aroma that has already been detected by the photoionization detector to avoid affecting the accuracy of the detection data.

[0034] The following is an example of an active gas delivery method. After adjusting the temperature and humidity of the clean carrier gas, it is delivered to one end of the sample to be tested at a fixed flow rate. The gas coming out from the other end contains aroma substances and is directly sent to the aroma collection device for concentration detection. The aroma after concentration detection is directly discharged (i.e., a non-closed gas path is formed).

[0035] Specifically, the aroma sampling module 200 includes a sample carrier cavity for accommodating the sample to be tested and an aroma collection device in an initial empty state. The sample carrier cavity is a closed cavity with an axial airflow channel, and the airflow channel is axially aligned with and connected to the internal pores of the sample to be tested, ensuring that the carrier airflow passes through the entire effective section of the sample to be tested.

[0036] Meanwhile, the sealed cavity is provided with a first port and a second port at both ends. The first port receives the target clean carrier gas, and the second port outputs the aroma carrier gas to the aroma collection device. The outlet port of the aroma collection device is connected to the gas detection module. After the aroma concentration is detected by the gas detection module, the waste gas is directly discharged.

[0037] During operation, a precisely controlled target clean carrier gas, flowing at a preset flow rate (e.g., 35 ml / 2 sec, simulating single-port suction), is introduced from the first port of the sample-bearing chamber, passing through the sample to be tested and carrying away the released aroma substances, forming an aroma-carrying gas. This aroma-carrying gas then passes through the second port, without any diversion or intermediate adsorption, and is entirely and directly transported and stored in the pre-emptied gas sampling bag. This "endpoint-based full-volume collection" method ensures that the aroma substances released from the sample to be tested are collected without fractionation or secondary loss, thus accurately reflecting the total amount of aroma released from the sample in a single instance or cumulatively under simulated operating conditions, ensuring the accuracy of aroma substance concentration detection.

[0038] Preferably, the aroma collection device is a flexible gas sampling bag, whose air inlet is connected to the second port of the sample carrier chamber via an airtight pipe. This airtight pipe can also be equipped with a control valve. Before sampling, the air inside the sampling bag is completely emptied and kept under negative pressure, creating an initial condition of "empty bag ready to be filled." As those skilled in the art know, the gas sampling bag is made of an inert material with low adsorption of the target aroma substance, such as a polytetrafluoroethylene (PTFE), perfluoroethylene propylene (FEP), polyvinyl fluoride (PVF) liner, or a silanized aluminum foil composite film, thereby ensuring the accuracy of aroma substance concentration detection.

[0039] Similarly, in other embodiments, unidirectional detection systems with other structures or connection methods can also be used, all of which are within the protection scope of this invention and will not be described in detail here.

[0040] To further improve the effectiveness of rapid aroma concentration detection, in a preferred embodiment, step 4 further includes the following steps: Step 401: Adjust the target temperature and humidity values, target suction flow rate, and target suction volume of the target clean carrier gas by a preset range to establish a continuous detection scheme. Step 402: Detect and record multiple concentration values ​​of the same sample based on the continuous detection scheme, and generate a concentration change curve; Step 403: Compare the concentration change curves of multiple test samples in the same batch to generate consistency assessment results.

[0041] The above preferred embodiment simulates different human smoking modes and sets corresponding test conditions for the test samples and continuously detects them to obtain the aroma concentration change curve of the test sample, that is, the aroma change state felt by the human body during continuous smoking. In this way, the concentration change curves of multiple test samples in the same batch are compared to ensure that the user's perception of aroma change is consistent when smoking each cigarette, thereby improving the user experience.

[0042] In practical applications, depending on the usage scenario, such as the required detection accuracy or efficiency, one or a combination of the above two detection systems and methods can be used. For example, for multiple samples to be tested in the same batch, a closed-loop detection system and a unidirectional detection system can be used for consistency detection, and the detection results of the two systems can be combined to further improve the accuracy of the detection results.
