Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a food testing distillation and purification device. Background Technology

[0002] With the rapid development of the food industry, the safety and accuracy of food quality testing have become the focus of global consumers. In order to ensure the safety and quality of food, food testing technology plays a crucial role in the testing process. In the food testing process, distillation purification technology is widely used for the separation and concentration of sample components, especially when extracting target substances from liquid foods or complex matrices, where distillation technology has high separation efficiency.

[0003] In current distillation methods, the food to be tested is placed in a distillation flask, and all the moisture in the food is evaporated through distillation. The water is then collected in a beaker. Since the moisture is on the inside of the food, it will precipitate out from the inside of the food when heated, requiring continuous heating, which results in low distillation efficiency.

[0004] An existing patent (publication number: CN221733398U) discloses a novel food inspection and testing distillation device, comprising a base and a fixing block. One end of the base is fixedly connected to the fixing block, and one end of the fixing block is fixedly connected to a distillation flask. One end of the distillation flask is connected to a condenser tube, and a collecting cup is placed at the outlet end of the condenser tube. An end cap is screwed to the opening of the distillation flask. A squeezing mechanism is provided inside the distillation flask. Through the combination of the end cap, screw, turntable, pressure plate, limiting cylinder, filter plate, and filter holes, food can be filtered, temporarily stored on the surface of the filter plate. Simultaneously, the pressure plate squeezes the food on the filter plate, causing the moisture in the food to be quickly extracted, thereby reducing heating time and improving distillation efficiency.

[0005] Existing patents offer solutions to the above problems, but they have limitations such as the inability to add raw materials to the distillation flask during the distillation process and the inability to ensure uniform heating of the raw materials inside the distillation flask.

[0006] Therefore, a food testing and distillation purification device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a food testing distillation and purification device that can solve the problems of existing food testing distillation devices, such as the inability to add raw materials into the distillation flask during the distillation process and the inability to uniformly heat the raw materials inside the distillation flask.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a food testing distillation and purification device, including a mounting frame, a heating device on the top of the mounting frame, a distillation flask on the top of the heating device, a connector on the top of the distillation flask, a condenser tube on one side of the connector, a collection bottle connected to the bottom of the condenser tube, a feeding mechanism in the middle of the connector, and a gas processing mechanism in the middle of the collection bottle;

[0009] The feeding mechanism includes a support base disposed on the side wall of the mounting frame, one end of the support base being fixedly connected to a connector, an inclined tube disposed on the side wall of the connector, a feeding hopper disposed on the side wall of the inclined tube, a push rod disposed in the middle of the inclined tube, a plug disposed at one end of the push rod, the plug being movably disposed inside the inclined tube, a connecting assembly disposed between the connector and the distillation flask, and a stirring assembly disposed in the middle of the connector.

[0010] Preferably, the connecting assembly includes a connecting ring threaded to the bottom of the connector, and a insertion ring is provided at the bottom of the connecting ring, the insertion ring being inserted into the top of the distillation flask.

[0011] Preferably, the stirring assembly includes a drive motor disposed on the top of the connector, the output end of the drive motor is fixedly connected to a stirring shaft, and a stirring wheel is disposed at the bottom of the stirring shaft.

[0012] Preferably, the gas processing mechanism includes a connecting cap disposed on the side wall of the mounting frame, a bent tube disposed in the middle of the connecting cap, one end of the bent tube being connected to a condenser tube, a liquid collecting bottle adapted to the connecting cap, a vent pipe disposed at the top of the connecting cap, the vent pipe being U-shaped, a processing bottle disposed on one side of the liquid collecting bottle, one end of the vent pipe being located inside the processing bottle, and a processing liquid disposed inside the processing bottle.

[0013] Preferably, the heating device includes a lifting rod threadedly connected to the middle of the mounting frame, a heating seat rotatably connected to the top of the lifting rod, a heating block provided on the top of the heating seat, and the heating block in contact with the distillation flask.

[0014] Preferably, a condenser cover is provided on the side wall of the condenser tube, and a liquid exchange head is provided at both ends of the condenser cover.

[0015] Preferably, a limiting ring is movably provided at the bottom of the connecting cap, and the limiting ring is adapted to the liquid collection bottle.

[0016] Preferably, the mounting bracket has an L-shaped mounting plate on its side wall.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates a feeding mechanism. When additional raw materials are added during the distillation process, the raw materials are added through the feeding hopper. The push rod opens the inclined tube channel through the plug, enabling quantitative additional feeding. The drive motor rotates the stirring shaft and stirring wheel, ensuring uniform heating of the sample. Through the feeding mechanism, the inclined tube, feeding hopper, push rod, and plug work together to add additional raw materials into the connector through the inclined tube. After feeding, the plug seals the feeding hopper, achieving a sealed connection. This achieves the effect of adding raw materials into the distillation flask during the distillation process while simultaneously agitating the raw materials inside the flask, ensuring uniform heating.

[0019] 2. This application incorporates a gas processing mechanism. During use, the volatile gases generated during distillation are introduced into the vent pipe through the inclined tube in the connecting cap, following the incompletely condensed residue in the condenser. The U-shaped vent pipe forms a liquid seal structure, preventing backflow of external air and ensuring unidirectional gas flow to the processing bottle. After entering the processing bottle, the gas reacts chemically with or is adsorbed by the pre-set processing liquid (such as acid-base absorption liquid, oxidant solution, etc.). The matching design of the limiting ring and the collection bottle ensures the sealing of the connection, preventing the leakage of harmful gases. In this way, the gas generated during distillation is collected and processed through the gas processing mechanism, avoiding the leakage of harmful gases. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A food testing distillation and purification device includes a mounting frame 1, a heating device 2 on the top of the mounting frame 1, a distillation flask 3 on the top of the heating device 2, a connector 4 on the top of the distillation flask 3, a condenser 5 on one side of the connector 4, a collection bottle 6 connected to the bottom of the condenser 5, a feeding mechanism 7 in the middle of the connector 4, and a gas processing mechanism 8 in the middle of the collection bottle 6.

[0031] The feeding mechanism 7 includes a support base 71 disposed on the side wall of the mounting frame 1. One end of the support base 71 is fixedly connected to the connector 4. An inclined tube 72 is disposed on the side wall of the connector 4. A feeding hopper 73 is disposed on the side wall of the inclined tube 72. A push rod 74 is disposed in the middle of the inclined tube 72. A plug 75 is disposed at one end of the push rod 74. The plug 75 is movably disposed inside the inclined tube 72. A connecting assembly 76 is disposed between the connector 4 and the distillation flask 3. A stirring assembly 77 is disposed in the middle of the connector 4.

[0032] Specifically, such as Figure 3 As shown, the connecting assembly 76 includes a connecting ring 761 threaded to the bottom of the connector 4, and a plug ring 762 is provided at the bottom of the connecting ring 761, which is inserted into the top of the distillation flask 3.

[0033] Specifically, such as Figure 3As shown, the stirring assembly 77 includes a drive motor 771 disposed on the top of the connector 4, and a stirring shaft 772 is fixedly connected to the output end of the drive motor 771. A stirring wheel 773 is disposed at the bottom of the stirring shaft 772.

[0034] Specifically, such as Figure 3 As shown, the heating device 2 includes a lifting rod 9 threadedly connected to the middle of the mounting frame 1. A heating seat 10 is rotatably connected to the top of the lifting rod 9. A heating block 11 is provided on the top of the heating seat 10. The heating block 11 is in contact with the distillation flask 3.

[0035] Specifically, such as Figure 4 As shown, a condenser cover 12 is provided on the side wall of the condenser tube 5, and liquid exchange heads 13 are provided at both ends of the condenser cover 12.

[0036] Specifically, such as Figure 1 As shown, a mounting plate 15 is provided on the side wall of the mounting bracket 1, and the mounting plate 15 is L-shaped.

[0037] In use, first place the distillation flask 3 on the heating base 10, rotate the lifting rod 9 to push the distillation flask 3 upward, so that the top of the distillation flask 3 mates with the connector 4. Then, rotate the connecting ring 761 downward, so that the insertion ring 762 at the bottom of the connecting ring 761 is inserted into the distillation flask 3. At the same time, the stirring shaft 772 and the stirring wheel 773 enter the interior of the distillation flask 3, achieving a quick and airtight connection between the distillation flask 3 and the connector 4, ensuring the airtightness of the distillation process. Distillation can then be performed. When adding additional raw materials during the distillation process, the materials are added through the feeding hopper 73. Pushing the push rod 74 opens the obstruction 75 to open the inclined tube 72 channel, achieving quantitative additional feeding. The drive motor 771 drives the stirring shaft 772 and the stirring wheel 773 to rotate, ensuring uniform heating of the sample and preventing... To prevent localized overheating or violent boiling, the heating block 11 precisely controls the temperature of the distillation flask 3. After the sample is heated, the volatile components evaporate, and the vapor enters the condenser tube 5 through the connector 4. It is condensed into liquid by the cooling medium (such as water) in the condenser hood 12. The condensed liquid flows into the collection bottle 6, completing the purification process. Through the setting of the feeding mechanism 7, the addition of additional raw materials to the inside of the connector 4 is achieved through the cooperation of the inclined tube 72, the feeding hopper 73, the push rod 74, and the plug 75. After the feeding is completed, the plug 75 seals the feeding hopper 73, achieving a sealing treatment of the connector 4. In this way, the effect of adding raw materials to the inside of the distillation flask 3 during the distillation process is achieved, and the raw materials inside the distillation flask 3 can be stirred at the same time, so that the raw materials are heated evenly.

[0038] Specifically, such as Figure 5As shown, the gas processing mechanism 8 includes a connecting cap 81 disposed on the side wall of the mounting bracket 1. A bent pipe 82 is disposed in the middle of the connecting cap 81. One end of the bent pipe 82 is connected to the condenser pipe 5. The liquid collection bottle 6 is adapted to the connecting cap 81. A vent pipe 83 is disposed on the top of the connecting cap 81. The vent pipe 83 is U-shaped. A processing bottle 84 is disposed on one side of the liquid collection bottle 6. One end of the vent pipe 83 is located inside the processing bottle 84. The processing bottle 84 contains processing liquid.

[0039] Specifically, such as Figure 5 As shown, a limiting ring 14 is movably provided at the bottom of the connecting cap 81, and the limiting ring 14 is adapted to the liquid collection bottle 6.

[0040] In use, the volatile gases generated during distillation are introduced into the vent pipe 83 through the incompletely condensed residue in the condenser 5 via the inclined tube 72 in the connecting cap 81. The U-shaped vent pipe 83 forms a liquid seal structure, which can prevent backflow of external air and ensure unidirectional gas flow to the treatment bottle 84. After entering the treatment bottle 84, the gas reacts chemically with the pre-set treatment liquid (such as acid-base absorption liquid, oxidant solution, etc.) or is adsorbed. The matching design of the limiting ring 14 and the collection bottle 6 ensures the sealing of the connection and prevents the leakage of harmful gases. In this way, the gas generated during distillation is collected and treated by the gas treatment mechanism 8 to avoid the leakage of harmful gases.

[0041] By adopting the above technical solution, the problems of existing food inspection and testing distillation devices being unable to add raw materials into the distillation flask 3 during the distillation process, and being unable to uniformly heat the raw materials inside the distillation flask 3, are solved.

[0042] Working principle: In use, the distillation flask 3 is first placed on the heating base 10. The lifting rod 9 is rotated to push the distillation flask 3 upwards, aligning the top of the flask with the connector 4. The connecting ring 761 is then rotated downwards, inserting the insertion ring 762 at its bottom into the distillation flask 3. Simultaneously, the stirring shaft 772 and stirring wheel 773 enter the interior of the distillation flask 3, achieving a quick and sealed connection between the distillation flask 3 and the connector 4. Distillation is then performed. When additional raw materials are added during distillation, they are added through the feeding hopper 73. Pushing the push rod 74 opens the inclined tube 72 channel via the plug 75, allowing for quantitative additional feeding. The drive motor 771 rotates the stirring shaft 772 and stirring wheel 773, ensuring uniform heating of the sample and preventing localized overheating or boiling over. The heating block 11... The distillation flask 3 is precisely heated at a controlled temperature. After the sample is heated, the volatile components evaporate, and the vapor enters the condenser tube 5 through the connector 4. It is condensed into liquid by the cooling medium (such as water) in the condenser hood 12. The condensed liquid flows into the collection bottle 6 to complete the purification. The volatile gas generated during the distillation process is introduced into the vent pipe 83 through the inclined tube 72 in the connector cap 81 as the incompletely condensed residue in the condenser tube 5. The U-shaped vent pipe 83 forms a liquid seal structure, which can prevent the backflow of external air and ensure that the gas flows unidirectionally to the treatment bottle 84. After the gas enters the treatment bottle 84, it reacts chemically with the preset treatment liquid (such as acid and alkali absorption liquid, oxidant solution, etc.) in the bottle or is adsorbed. The matching design of the limiting ring 14 and the collection bottle 6 ensures the sealing of the connection and prevents the leakage of harmful gases.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
