Description

Technical Field

[0001] This invention relates to the field of tobacco testing equipment technology, and in particular to a smart detection device system and method for sweeteners on the surface of cigarette tipping paper. Background Technology

[0002] Sweeteners are additives that impart sweetness to food. Appropriate addition can improve the taste and flavor of food. Non-sugar sweeteners, in particular, are favored by the food processing industry due to their low calorie content, high sweetness, heat and acid / alkali resistance, and the fact that they generally do not participate in metabolic processes. In recent years, with the continuous optimization of cigarette product structure, adding sweeteners to cigarette tipping paper has enhanced the aroma and improved the taste, gaining widespread popularity and recognition from consumers. However, the current methods for detecting the overall sweetener content in the industry yield results that differ from sensory experiences, and the procedures are cumbersome and difficult to implement on-site for large-scale testing.

[0003] CN108776187A discloses a method for detecting five sweeteners in cigarette tipping paper using ultra-high performance liquid chromatography-tandem mass spectrometry. The method involves first cutting the cigarette tipping paper into small pieces and soaking it in ultrapure water, then performing ultrasonic extraction. After filtering the extract and diluting it with ultrapure water, the sweeteners in the paper are directly determined by ultra-high performance liquid chromatography-tandem mass spectrometry.

[0004] CN113655138A discloses a method for determining the apparent sweetener in sweetened tipping paper. The method involves cutting a tipping paper of a predetermined area, laying it flat, and fixing it in place. Artificial saliva is added to the rough surface of a glass fiber filter and allowed to stand until the saliva is evenly dispersed on the glass fiber. The front side of the glass fiber is then held with tweezers, and the rough surface is brought into contact with the front side of the tipping paper. The filter is then wiped back and forth along the length of the tipping paper. The wiped glass fiber filter is placed in a stoppered conical flask. An extraction solution is added to the stoppered conical flask, and the mixture is extracted using ultrasound. After standing, the supernatant is collected, filtered through a membrane, and analyzed by chromatography.

[0005] The above-mentioned methods for detecting sweeteners in cigarette tipping paper still suffer from problems such as expensive testing equipment, high operating and maintenance costs, long testing time, and low testing efficiency. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention provides a smart detection device system and method for sweeteners on the surface of cigarette tipping paper. The system utilizes the control device in the intelligent control pan-tilt device to intelligently control the cigarette paper processing device, the filtering device, the quantitative processing device, and the data acquisition and analysis device, thereby realizing rapid and efficient detection of sweeteners on the surface of cigarette tipping paper. This is suitable for grassroots quality inspectors to conduct timely and effective quality control of the sweetness of cigarette tipping paper.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a smart detection device system for sweeteners on the surface of cigarette tipping paper, the smart detection device system for sweeteners on the surface of cigarette tipping paper includes a smart control pan-tilt device, a cigarette paper processing device, a filtering device, and a quantitative processing and data acquisition and analysis device connected in sequence;

[0009] The intelligent control PTZ device includes a control unit; the control unit is electrically connected to the cigarette paper processing unit, the filtration unit, the quantitative processing unit, and the data acquisition and analysis unit.

[0010] The intelligent detection device system for sweeteners on the surface of cigarette tipping paper described in this invention includes an intelligent control pan-tilt unit, a cigarette paper processing device, a filtering device, and a quantitative processing and data acquisition and analysis device connected in sequence. The control device in the intelligent control pan-tilt unit can precisely control the cigarette paper processing device, the filtering device, the quantitative processing and data acquisition and analysis device to perform automatic detection and analysis, realizing fully automatic operation, intuitive detection results, fast detection speed, and simple use. It is suitable for large-scale on-site quality inspection, thereby achieving precise quality control of sweeteners on the surface of cigarette tipping paper. Its core value lies in directly linking the detection results with actual sensory experience, providing decision support for enterprises to conduct research and development and quality control based on real flavor feedback, and effectively ensuring the stability of cigarette product flavor and excellent taste.

[0011] The control device described in this invention features a main control circuit designed based on a prototype, enabling fully automated control of the cigarette paper processing device, filtration device, quantitative processing device, and data acquisition and analysis device. The main control circuit communicates with a host computer via an RS232 serial port, receiving test commands and controlling the cigarette paper processing device, filtration device, quantitative processing device, and data acquisition and analysis device to complete specified actions. During operation, the main control circuit monitors the execution status of actions in real time, providing error alarms, anti-freezing, and automatic fault tolerance functions. The control device uses a host computer operation program developed in C# language. The program interface has a simple UI design, comprehensive functions, and intuitive display, enabling one-click operation of the cigarette paper processing device, filtration device, quantitative processing device, and data acquisition and analysis device, and providing real-time feedback on the device's operating status and fault conditions. The host computer language supports script operation, facilitating future adjustments and testing processes. Local log recording of equipment operating status facilitates troubleshooting. Operators can also use a mobile APP for one-click operation guidance, real-time status display, instant presentation and storage / export of test results, significantly reducing the operational threshold for frontline personnel. The software supports functions such as automatic calibration, function self-test, and data saving.

[0012] The data acquisition and analysis device of this invention is an electrochemical workstation, equipped with a carbon nanotube electrode cyclic voltammetry detection device. The working electrode of this detection device is a modified carbon nanotube electrode, specifically modified carbon nanotubes grafted with amino and / or hydroxyl groups. The data acquisition and analysis device of this invention can accurately detect the content of saccharin sodium sweetener on the surface of cigarette tipping paper. The main testing method includes: mixing saccharin sodium with acrylamide functional monomers, adding a crosslinking agent and an initiator to form an imprint material. During electropolymerization, the spatial orientation of the saccharin sodium template molecules is fixed, constructing an imprint layer with molecular recognition function. Finally, high-density specific binding sites are obtained through template elution, achieving sensitive detection of saccharin sodium. By constructing saccharin sodium specific recognition sites on the surface of the modified carbon nanotube electrode, the data acquisition and analysis device of this invention can effectively eliminate common interfering substances in the solution matrix (such as aspartame and acesulfame potassium), endowing the sensor with the ability to recognize saccharin sodium through a "molecular lock".

[0013] The data acquisition and analysis device is equipped with standard spectral parameters and a quantitative analysis model for sodium saccharin, established based on statistical analysis of electrochemical test signal data of sodium saccharin content in cigarette tipping paper. The accuracy of the quantitative model was verified by testing tipping papers with different sodium saccharin contents, and the model accuracy was adjusted and optimized. Simultaneously, by correlating the sweetener content with actual human sensory perception through a large amount of data, the sweetness of the sample is automatically displayed.

[0014] Preferably, the intelligent control gimbal device includes a support and a robotic arm connected to the support. The robotic arm can automatically suck up air and then pick up the cigarette tipping paper to be tested and transfer it to the cigarette paper processing device for processing, without the need for manual operation.

[0015] Preferably, the cigarette paper processing device includes a sample pool, a sample clamping device, and a flexible grinding wheel.

[0016] Preferably, both the sample clamping device and the flexible grinding wheel are positioned above the sample pool.

[0017] Preferably, the sample clamping device includes an upper metal surface and a lower metal surface.

[0018] The materials of the upper and lower metal surfaces described in this invention include stainless steel.

[0019] Preferably, the cigarette paper processing device includes a water inlet and an air duct connected to the lower metal surface, wherein the water inlet sprays water to clean the entire sample pool and the flexible grinding wheel, and the air duct blows air to dry the entire cigarette tipping paper surface sweetener intelligent detection device system.

[0020] Preferably, the cigarette paper processing device further includes a microwave extraction device disposed below the sample cell.

[0021] This invention does not impose specific limitations on the microwave extraction device; any microwave extraction device existing in the field may be used.

[0022] Preferably, the filtration device contains a filter membrane.

[0023] This invention does not impose detailed limitations on the material of the filter membrane; a suitable filter membrane can be selected based on the composition of the extract to be filtered.

[0024] Secondly, the present invention also provides a smart detection method for sweeteners on the surface of cigarette tipping paper, wherein the smart detection method for sweeteners on the surface of cigarette tipping paper is performed using the smart detection device system for sweeteners on the surface of cigarette tipping paper described in the first aspect; the smart detection method for sweeteners on the surface of cigarette tipping paper includes the following steps:

[0025] (1) The robotic arm in the intelligent control gimbal device picks up the cigarette paper to be tested and moves it onto the upper metal surface of the cigarette paper processing device;

[0026] (2) The lower metal surface and the upper metal surface automatically engage, exposing the part of the cigarette tipping paper to be tested to be processed in the sample cell; the flexible grinding wheel starts to rotate, and the surface of the cigarette tipping paper to be tested is brushed.

[0027] (3) The water jet from the water inlet of the cigarette paper processing device rinses the entire sample cell and the flexible grinding wheel, and the rinsing solution enters the microwave extraction device for extraction.

[0028] (4) The extract is sequentially processed by a filtration device and a quantitative processing device to obtain the sample to be tested;

[0029] (5) The data acquisition and analysis device analyzes and tests the sample to be tested to obtain the content X of sweetener on the surface of cigarette tipping paper;

Then, the lower and upper metal surfaces automatically engage. A flexible grinding wheel is used to brush the surface of the cigarette tipping paper to separate the sweeteners from the paper. Next, the entire sample cell and the flexible grinding wheel are rinsed, and the collected rinsing liquid enters a filtration device to remove impurities. After rinsing, it enters a quantitative processing device, where an appropriate solution is added to bring the volume to a specified mark. The sample is then vortexed and allowed to stand, resulting in a sample suitable for automatic detection and analysis by a data acquisition and analysis device. The data acquisition and analysis device analyzes and tests the sample to quickly determine the content of sweeteners on the surface of the cigarette tipping paper. The data acquisition and analysis device can automatically display the sweetness of the cigarette tipping paper based on the content of sweeteners on its surface. This invention does not specify a particular solution for the quantitative processing device; those skilled in the art can use a suitable solution for volume adjustment according to the actual situation.
