TECHNICAL FIELD

[0001] The present application relates to the technical field of tobacco detection, in particular to a tobacco volatile component extraction device. BACKGROUND

[0002] The volatile components in cigarette tobacco are various in type and widely distributed in content, and have great differences among different cigarettes, and have important influence on the sensory quality and style characteristics of products. With the wide application of auxiliary material flavoring technology such as cigarette paper flavoring, formed paper flavoring, tobacco adhesive flavoring and packaging material flavoring in cigarette production, the influence of volatile components in auxiliary materials on the style characteristics of cigarette products has been increasingly concerned by researchers. Obtaining cigarette volatile components not only helps to understand the formation trend of cigarette product style characteristics, but also provides theoretical reference for product design and processing technology. In order to obtain cigarette volatile components, researchers generally classify and detect tobacco and various auxiliary materials, but this method is time-consuming and laborious, and the data obtained has poor comparability.

[0003] The patent with the application publication number CN104713965A discloses a tobacco volatile and semi-volatile flavor component extraction method, and also discloses a tobacco volatile and semi-volatile flavor component extraction device, which comprises a gas pump, a sample bottle, a temperature-controlled water bath heating pot, an air inlet pipe, an air outlet pipe and a trapping pipe. The gas pump is provided with a first air inlet and a first air outlet. The sample bottle is located in the temperature-controlled water bath heating pot, and is provided with a second air inlet and a second air outlet. One end of the air inlet pipe is connected with the first air outlet of the gas pump, and the other end of the air inlet pipe is inserted into the sample bottle through the second air inlet. One end of the air outlet pipe is inserted into the sample bottle through the second air outlet, and the other end of the air outlet pipe is connected with the first air inlet of the gas pump through the trapping pipe.

[0004] The above-mentioned tobacco volatile component extraction device is simple and easy to operate, but it only blows air into the sample bottle through one air inlet pipe. The position of the tobacco in the sample bottle is fixed, the tobacco is not evenly heated, and the tobacco cannot be turned over. The air flow can only blow air to the same point, resulting in low tobacco sweeping and trapping efficiency. SUMMARY

[0005] Therefore, the present application aims to provide a tobacco volatile component extraction device which can evenly heat the tobacco in the sample bottle, roll and sweep the volatile components in the tobacco, and has higher tobacco volatile component sweeping and trapping efficiency.

[0006] The present application solves the above technical problems through the following technical means:

[0008] Further, the first inner thread is arranged on the inner wall of the opening portion of the sample bottle, the first outer thread is arranged on the outer periphery of the filter cartridge, and the sample bottle and the filter cartridge are screw-connected through the first inner thread and the first outer thread. In use, the filter cartridge can be screwed off from the sample bottle, then the tobacco is placed in the sample bottle and laid on the bearing plate with the first ventilation holes, and then the filter cartridge is screwed onto the sample bottle. In this way, the filter cartridge and the sample bottle can be screw-connected and detached, facilitating the placement and removal of the tobacco.

[0009] Further, the outlet end of the air inlet pipe and the fixed disc are on a vertical line. When the air flow from the air pump enters the wind power regulation cavity from the outlet end of the air inlet pipe, the outlet end of the air inlet pipe and the fixed disc are on a vertical line, which can uniformly blow the wind to the wind blades, so that the wind blades can rotate at a lower wind speed.

[0010] Further, the rotation shaft is provided with a disc at one end of the accommodating cavity, and the rotation connecting portion of the rotation shaft and the bearing plate is lined with a rolling bearing. The disc can hang the rotation shaft and the wind blades on the bearing plate, and the rolling bearing can make the rotation shaft rotate more labor-saving.

[0012] Further, the said constant temperature heater is a water bath, a plurality of second through holes are arranged on the hanging ears, a hanging rod is arranged in each second through hole, a counterweight is detachably arranged on the hanging rod, a first stop block is arranged at one end of the hanging rod, and a second stop block is threadedly connected to the other end of the hanging rod, and a notch groove is arranged on the counterweight. When the sample bottle is placed in the water bath, the hanging rod is passed through the second through hole, the end of the hanging rod is threadedly connected to the second stop block, and the counterweight is hung on the hanging rod through the notch groove. The use amount of the counterweight can be adjusted according to the required depth of the water bath, so that the sample bottle can be prevented from floating in the water bath, and the tobacco heating is uniformly avoided.

[0013] Further, the said air inlet pipe is fixedly connected with a horn mouth at one end of the wind force adjusting cavity, and the opening end of the horn mouth faces the fixing disc. The setting of the horn mouth can increase the wind force area of the air outlet pipe, and can more powerfully blow the wind blade to rotate.

[0014] Further, the said adsorbent includes a mixture of activated carbon and glass wool. The activated carbon and glass wool can well adsorb the volatile components in the tobacco, and it should be noted that the adsorbent can not only be activated carbon and glass wool, but also various natural or synthetic adsorbents.

[0015] Further, the said air inlet pipe is fixedly connected with a horn mouth at one end of the wind force adjusting cavity, and the opening end of the horn mouth faces the fixing disc. The setting of the horn mouth can increase the wind force area of the air outlet pipe, and can more powerfully blow the wind blade to rotate.

[0016] The beneficial effects of the present application are as follows:

[0017] When the present application is used, the air flow pumped by the air pump passes through the air inlet pipe, is sprayed from the horn mouth into the wind power adjusting cavity of the sample bottle, and when the air flow enters the wind power adjusting cavity, blows the wind blades, so that the wind blades rotate under the blowing of the air flow sprayed from the horn mouth. Because the length of each wind blade is not equal, when the fixed disc rotates, it will drive the wind blades to blow the bearing plate at a non-uniform speed. In this way, the non-uniform wind power passes through the first ventilation hole to blow the tobacco on the bearing plate. Because the wind power received by the tobacco on the bearing plate is large and small, and the weight of each part of the tobacco is not completely uniform, the tobacco will continuously roll up and down in the containing cavity under the condition of large and small wind blowing and uneven gravity. In the up and down rolling, the tobacco is heated more uniformly in the sample bottle, and basically each part can be swept by the wind power, so that the volatile components in the tobacco can be more quickly released, and the sweeping and capturing efficiency of the volatile components of the tobacco is higher.

[0030] The use method of the present application is as follows:

[0031] Before use, the tobacco to be extracted of volatile components is placed in the accommodating cavity 7 of the sample bottle 2, and the tobacco is laid on the bearing plate 5 with the first ventilation hole 6, and then the filter cartridge 15 is screwed onto the sample bottle 2, so that the filter cartridge 15 and the sample bottle 2 are threadedly connected through the first inner thread and the first outer thread. Then the plug block 22 is plugged on the filter cartridge 15, and the air outlet pipe 23 is inserted into the first through hole of the plug block 22.

[0032] The first inch pipe 25 and the second inch pipe 26 are filled with activated carbon and glass wool, and it should be noted that the adsorbent can be not only activated carbon and glass wool, but also various natural or synthetic adsorbents, and then the first inch pipe 25 and the second inch pipe 26 are connected through the second outer thread 28 and the second inner thread.
