Description

Technical Field

[0001] The invention relates to the field of optics and tobacco component detection, and in particular to an integrated system for tobacco pre-treatment and rapid component spectral detection. Background Art

[0002] The chemical composition of tobacco is an intrinsic factor that determines the quality of tobacco. For example, the conventional components that are essential in tobacco quality evaluation and formula design include total alkaloids, reducing sugars, total sugars, total nitrogen, total potassium, etc. There are also chemical components used to reflect the style and quality of tobacco, cigarette style and quality, such as tobacco polyphenols, amino acids, etc. Therefore, it is of great significance to test the components in tobacco and timely grasp the nutritional components in tobacco to improve the quality of tobacco.

[0003] At present, the detection of tobacco components mainly adopts chemical analysis methods, such as continuous flow method, ion chromatography, ICP-MS method, etc. Although these methods are accurate, they have problems such as not being able to measure multiple components at the same time, requiring complex sample pretreatment, being time-consuming and labor-intensive, and having a long analysis time, and cannot meet the requirements of rapid quality control.

[0004] In the prior art, near-infrared spectroscopy is used for chemical component detection. This technology is based on the characteristic near-infrared band absorption exhibited by hydrogen-containing groups, and has the advantages of being fast, non-destructive, green, low-cost, and requiring no special pretreatment. It has good applications in tobacco classification and component analysis, and can detect the content of chemical components such as moisture, chlorophyll, and nitrogen in tobacco.

[0005] Due to the different sizes and roughness of tobacco leaves, if near-infrared spectroscopy is used directly to detect tobacco, there will be large errors. One idea is to design the detection algorithm based on the detection method itself. The detection samples are still samples with the above defects. The results obtained through the prediction and reasoning of the algorithm will also deviate from the accurate results and require more computing resources. Summary of the invention

[0062] Refer to Figure 1 , the detection chamber discharge pipe 18 is connected to the feed port of the sample storage device by installing the suction device 6 on the sample storage device;

[0063] Further references Figure 4 , Figure 5 , Figure 7 and Figure 8 The spectrum detection device 31 of this embodiment includes 8 fans, a slide rail 20, a stepper motor 24, a power supply 25, a spectrum detection device cover 22, a T-shaped bracket 12, 3 halogen lamp cups 14, a transmission lamp support seat, 2 reflector lamp support seats, a control device 21 and a spectrum sensor.

[0064] The overall structure of the spectrum detection device is divided into three parts from top to bottom:

[0065] The upper part contains: power supply and control device;

[0066] The middle part includes: a slide rail 20, a stepper motor, a T-shaped bracket, two halogen lamp cups, two reflector lamp support seats and a spectrum sensor 32;

[0067] The slide rail 20 is vertically installed in the middle position of the spectrum detection device and is close to the inner wall (the slide rail and the shell are connected by screws). The stepper motor is above the slide rail; the T-shaped bracket is connected to the slide rail through the sliding block, and the sliding block slides under the drive of the stepper motor;

[0068] The T-shaped bracket is connected to two reflector lamp support seats 13 and a spectrum sensor 32. The spectrum sensor is located in the center of the T-shaped bracket.

The bracket arm of the T-shaped bracket is bent downward by 45 degrees, and the transmission lamp holder carried on it can move left and right along the bracket arm.

[0070] Between the middle and lower parts is the detection chamber 17;

[0071] There is a transmission lamp support seat 16 and a halogen lamp cup 14 connected thereto in the center of the lower part.

[0072] The right end of the detection chamber 17 is connected to the detection chamber feed pipe and then to the T-tube, and the left end outlet is connected to the detection chamber discharge pipe and then to the suction device.

[0073] The sample storage device is connected to the suction device and is located directly below the suction device.

[0074] The operation process of the integrated spectrum detection system of this embodiment includes the following steps:

[0075] Set the working parameters of the drying and crushing device and preheat the spectrum detection device. The preheating method is:

[0076] When testing different varieties of tobacco, the operating temperature and humidity of the drying and crushing device should be adjusted, the halogen lamp of the spectrum detection device should be turned on, and the spectrum detection device should be preheated.

[0077] 2) In the initial state:

[0078] The tobacco is put into the drying and crushing device. The drying and crushing device controls the drying process in real time through the temperature and humidity detection device and the ceramic heating plate. After the drying is completed, the motor drives the crushing knife to rotate and crush the tobacco. There is a small particle filter control valve at the discharge port of the tobacco drying and crushing device. When it is closed, only small particles are allowed to pass.

[0079] 3) When the small particle filter control valve is closed, the suction device in the intermediate storage device is activated to suck tobacco particles into the intermediate storage device. The discharge port of the intermediate storage device is connected to a T-shaped tube, and the other two ends of the T-shaped tube are provided with a first control valve and a second control valve, which are connected to the waste collection bottle and the detection chamber respectively.

[0080] 4) The suction device on the sample collection device is started, the first control valve is closed, and the second control valve is opened. The gas filter control valve is closed. When the gas filter control valve is closed, only gas is allowed to pass through, and tobacco particles cannot pass through. At this time, under the action of suction, tobacco particles accumulate in the detection chamber.

[0081] 5) The spectral sensor collects spectral information. After the collection is completed, the spectral collection results are displayed on the display screen and in the computer software.

[0082] 6) The gas filter control valve is opened, and the tobacco particles in the detection chamber are moved to the sample storage device under the action of the suction device.

[0083] 7) The small particle filter control valve is opened, the second control valve is closed, the first control valve is opened, and the suction device in the intermediate storage device is started to suck the waste in the drying and crushing device to the intermediate storage device, and then the waste is transferred to the waste storage device under the action of gravity.

[0084] In this example, the material of the detection chamber is quartz glass.

[0085] The control device may adopt a control device with a controller such as a single chip microcomputer as the core.

[0086] The spectral sensor uses the AS7265X spectral sensor, which has temperature detection and spectral detection functions. The control device obtains the temperature information on the sensor to control the start and stop of the cooling fan. At the same time, the control device obtains the collected spectral information and displays it on the control panel. The control device also controls the stepper motor to drive the T-shaped bracket on the control rail to move up and down, and controls the switch of each halogen lamp through a relay.

[0087] Small particle filter control valves and gas filter control valves can be selected from commercially available products.

[0088] Small particle filter control valve optional products are:

[0089] The working principle of a small pneumatic Y-type filter (such as the DN15-DN200 model of the Li Yongda brand) is to use a Y-type structure with a filter screen inside. After the gas sucked by the air pump enters, small solid particles pass through the filter screen with the gas, and large solid particles are intercepted. The opening and closing of the valve is controlled by pneumatic drive to achieve control of airflow and particles.

[0090] It can also be a micro electric T-type filter. After the fluid enters the filter cartridge with the filter screen, large solid impurities are blocked, and small solid particles and gas are discharged from the filter outlet. The valve opening and closing is controlled by the electric drive device, and the filtering process can be accurately controlled as needed.

[0091] Gas filter control valve optional products are:

[0092] Small stainless steel ball valve with filter screen, the valve is opened and closed by rotating the ball, the ball is provided with through holes, and the gas flows through the through holes. A filter screen is installed at the inlet end of the valve to filter solid particles in the gas.

[0093] Needle-type gas filter valves usually use needle-type valve cores to control the gas flow rate by rotating the needle-type valve stem. A fine filter is built into the valve body, and the gas flows out through the channel controlled by the valve core after being filtered by the filter, effectively blocking solid particles.
