Description

TECHNICAL FIELD

[0001] The present application relates to the field of traditional Chinese medicine processing and quality detection technology, and particularly relates to a fermentation device for traditional Chinese medicine detection. BACKGROUND

[0002] Traditional Chinese medicine fermentation is a key processing link that uses the metabolic action of microorganisms to transform, degrade or synthesize effective components in traditional Chinese medicine, so as to improve the activity of the medicine, reduce the side effects, and enhance the efficacy. The fermentation detection as a core means to control the quality of traditional Chinese medicine fermentation needs to analyze the content of effective components, the number of microorganisms, the pH value and other indicators in the fermentation broth through real-time sampling, so as to accurately judge the fermentation progress and endpoint, and ensure that the final product meets the quality standards.

[0003] However, the traditional traditional Chinese medicine fermentation device has many deficiencies in practical application, and it is difficult to meet the efficient and accurate fermentation and detection requirements: firstly, the functions are scattered, and cleaning, fermentation and sampling need to rely on multiple independent devices. The medicine is easily polluted by the outside world during the transfer process between the devices, and the operation process is complicated, which greatly reduces the processing efficiency; secondly, the cleaning effect is not good, and simple mechanical stirring cleaning is often used, which has stirring dead angles and cannot completely remove the dirt and stubborn stains on the surface of the medicine, and some devices use chemical cleaning agents, which are easy to remain and interfere with the subsequent fermentation and detection results; thirdly, the sampling design is unreasonable, a large amount of fermentation broth needs to be extracted during sampling, which easily destroys the liquid level, concentration and microbial environment of the fermentation system inside the tank, leading to interruption of the fermentation process or distortion of the detection results, and the sampling assembly lacks effective self-cleaning structure, and the residual sample easily causes cross contamination, affecting the accuracy of subsequent detection; fourthly, the operation controllability is poor, and there is a lack of intuitive liquid level monitoring means, it is difficult to accurately control the amount of fermentation liquid and cleaning water, and the fermentation temperature regulation is unstable, which easily causes temperature to rise and fall suddenly, affecting the metabolic activity of microorganisms and the transformation of effective components of the medicine.

[0004] Therefore, the present application provides a fermentation device for traditional Chinese medicine detection, which integrates the cleaning stirring assembly, the sampling assembly and the heating tank, the liquid level tube and other structures in a single carrier of the tank body, cooperates with the three-stage cleaning (bubble cleaning-high temperature steam cleaning-supplementing water final washing), non-interference sampling (only a small amount of sample is taken) and steam self-cleaning design, realizes the integration of the whole process of traditional Chinese medicine “cleaning-fermentation-sampling detection” and non-pollution operation, solves the problems of scattered functions, incomplete cleaning and sampling interference of the traditional device, and improves the accuracy and convenience of fermentation and detection through visual control and constant temperature regulation, effectively guarantees the fermentation quality and detection result reliability of traditional Chinese medicine.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present application will be described in detail by referring to the attached drawings, however the present application can be realized in various different forms, therefore the present application is not limited to the embodiments described below, and in order to more clearly describe the present application, components not connected with the invention will be omitted from the drawings; The technical solutions in the embodiments of the present application are to solve the problems in the above background art, and the general idea is as follows: Embodiment: Please refer to Figures 1 to 11 As shown in the figure, the present embodiment introduces the specific structure of a fermentation device for traditional Chinese medicinal material detection, taking the tank body 1 as the core working cavity, integrating a clean stirring assembly (realizing medicinal material stirring and multi-mode cleaning), a sampling assembly (realizing non-interference sampling and self-cleaning), and cooperating with auxiliary structures such as a heating tank 9 (providing a steam source), a slag blocking net 14 (solid-liquid separation), a liquid level pipe 28 (liquid level monitoring), etc., to form a "cleaning-fermentation-sampling" full-process integrated equipment; The clean stirring assembly includes a motor 2 installed at the top end of the tank body 1, the output end of the motor 2 is connected to a hollow rotating shaft 29 vertically downward, the rotating shaft 29 extends to the middle and lower part inside the tank body 1 through the top end, and a group of stirring blades 3 in spiral staggered arrangement are installed on the outside of the rotating shaft 29, and the rotating shaft 29 and the stirring blades 3 are both rotated in the inside of the tank body 1 by the motor 2; Compared with the stirring blades of the traditional stirring device, the stirring blades 3 of the present application are in spiral staggered arrangement, starting from the lowermost side and spirally arranged upwards in turn, starting from the lowermost stirring blade 3, each stirring blade 3 upwards is staggered by 30° in the clockwise direction, and the height difference between the top end of the lower stirring blade 3 and the bottom end of the adjacent upper stirring blade 3 is 10-20 cm, which is specifically designed according to the size of the tank); This design enables the lower stirring blade 3 to turn up the medicinal materials at the bottom of the tank body 1 when the motor 2 drives the rotating shaft 29 to rotate, and the medicinal materials are transferred layer by layer by the multiple stirring blades 3, and finally moved to the upper side of the tank body 1, eliminating the stirring dead angle and ensuring that all medicinal materials are uniformly contacted with the cleaning medium or fermentation liquid; The stirring blade 3 has a hollow interior and a set of vent ports 4 on its surface. Each vent port 4 has a sliding groove 5 in the middle. Each sliding groove 5 has two opposing sliding rods 7 slidably connected inside. Each opposite end of the two sliding rods 7 is fixedly connected to a sealing cover 6. A spring 8 is sleeved on the outer side of the adjacent sliding grooves 5 and sliding rods 7. When the stirring blade 3 is filled with gas, the gas pressure will push the sealing cover 6 outward, thereby opening the vent ports 4 and allowing the gas inside the stirring blade 3 to be discharged from the vent ports 4. When the sealing cover 6 moves outward, it drives the sliding rods 7 to move inside the sliding grooves 5, thereby causing the sliding grooves 5 and sliding rods 7 to compress the spring 8. When the gas inside the stirring blade 3 is closed and no longer compresses the sealing cover 6, the spring 8 rebounds, pushing the sliding rods 7 to reset and then driving the sealing cover 6 to reset, so that the sealing cover 6 closes the vent ports 4 again. The interior of the rotating shaft 29 is hollow and is connected to the stirring blade 3. A heating tank 9 is installed on the rear side of the tank body 1. The heating tank 9 has a built-in electric heating tube (power 2000W) that can heat the water stored inside to 100-120℃ to generate steam. A steam pipe 10 is installed at the top of the heating tank 9. A valve 31 is installed in the middle of the steam pipe 10. A steam chamber 11 is installed at the output end of the steam pipe 10. A rotating chamber 12 is installed on the upper side of the rotating shaft 29. A steam outlet 13 is opened inside the rotating chamber 12. The rotating chamber 12 rotates inside the steam chamber 11. Steam is generated by the water inside the heater of the heating tank 9. After opening the valve 31, the steam passes through the steam pipe 10 and then through the steam outlet 13 to the interior of the rotating shaft 29. Then, the steam is transported to the interior of the stirring blade 3 through the rotating shaft 29 and finally discharged from the exhaust port 4. Steam delivery path: Steam generated by heating tank 9 → valve 31 → steam pipe 10 → steam chamber 11 → rotating chamber 12 steam outlet 13 → hollow rotating shaft 29 → hollow stirring blade 3 → exhaust port 4, and finally sprayed into the interior of tank 1 for cleaning; Specifically, barrier nets 30 can be installed on opposite sides of the two sealing caps 6. The design of the barrier nets 30 can prevent dregs and other debris from entering the interior of the barrier nets 30 through the exhaust port 4. Of course, if the barrier nets 30 are not installed, the size of the opening between the sealing caps 6 and the exhaust port 4 can also be adjusted to prevent dregs from entering. The size of the opening can be adjusted by changing the length of the slide rod 7, thereby adjusting its moving distance. The medicinal herbs are placed inside tank 1, and water is added. Motor 2 drives stirring blade 3 to continuously stir the herbs. Simultaneously, gas is discharged from exhaust port 4. The gas continuously sprays out from inside tank 1, while steam is discharged from exhaust port 4. This primarily enhances the cleaning effect on the herbs, achieved through three coordinated methods: Bubble cleaning in water environment: After adding water in the tank 1, the gas discharged from the exhaust port 4 forms a large number of bubbles in the water. The impact force generated during the rising of the bubbles cooperates with the mechanical stirring of the stirring blade 3 to accelerate the detachment of the mud and impurities attached to the surface of the medicinal materials, which can improve the cleaning efficiency compared with pure stirring; High-temperature steam cleaning in water-free environment: When there is no water in the tank 1, the high-temperature steam generated by the heating tank 9 enters the stirring blade 3 through the rotating shaft 29 and is directly injected to the surface of the medicinal materials from the exhaust port 4. The high temperature (100-120℃) of the steam realizes sterilization and disinfection, and softens stubborn stains. The stirring of the stirring blade 3 ensures that each medicinal material can contact the steam, ensuring that there is no dead angle in cleaning; Water replenishment final washing after steam cleaning: After completing steam cleaning, water is added to the tank 1 again, and the exhaust port 4 continuously sprays gas to generate bubbles. The motor 2 drives the stirring blade 3 to stir again. Through the dual action of water flow and bubbles, the remaining impurities after steam cleaning are thoroughly washed away. Finally, the sewage is discharged through the liquid outlet 25, and the entire cleaning process is completed. During the above cleaning process, the sealing mechanism composed of the sealing cover 6, the slide rod 7, the sliding groove 5 and the spring 8 can automatically adjust the opening degree according to the air pressure in the exhaust port 4, which can ensure the cleaning effect while avoiding excessive water or steam leakage. The blocking net 30 can effectively prevent the medicinal material debris from entering the inside of the stirring blade 3 to cause blockage, ensuring smooth gas flow; During the preparation stage of the cleaning stage, the charging port 27 is first opened, and traditional Chinese medicinal materials and appropriate cleaning water are added to the tank 1. The liquid level is confirmed through the liquid level pipe 28, and the charging port 27 is closed. Check the state of each valve (valve one 16, valve two 24 and valve three 31 are all closed); The sampling assembly includes a slag blocking net 14 installed inside the lower side of the tank 1 for isolating the medicinal materials and the liquid, and a liquid outlet bin 17 arranged at the bottom of the tank 1. The liquid outlet bin 17 is connected with the inside of the tank 1, and a pull rod 18 is slidably connected inside the liquid outlet bin 17. The pull rod 18 penetrates the inside and outside of the liquid outlet bin 17, and one end of the pull rod 18 inside the liquid outlet bin 17 is fixedly connected with a bin closing plate 19. The middle part and the other end outside the liquid outlet bin 17 are both fixedly connected with a partition plate 20. Locking blocks 21 are installed on the opposite sides of the two partition plates 20. The right end of the liquid outlet bin 17 is provided with two groups of locking grooves 22 inside and outside. The rotation locking between the locking blocks 21 and the locking grooves 22 can limit the movement of the pull rod 18; As Figure 11As shown, the closing plate 19 is used to close the opening between the liquid outlet 17 and the tank body 1. Pushing the pull rod 18 drives the closing plate 19 and the outer partition 20 to move inward simultaneously. After the closing plate 19 closes the opening between the liquid outlet 17 and the tank body 1, the right locking block 21 moves into the outer locking groove 22. Then, the outer partition 20 is rotated, which in turn drives the right locking block 21 to rotate and lock it with the outer locking groove 22, preventing the closing plate 19 from being pushed open under the action of water pressure. The locking block 21 has an arc-shaped structure, and the locking groove 22 is an arc-shaped groove that fits the locking block 21. The contact area when the locking block 21 and the locking groove 22 are engaged is not less than 2 / 3 of the surface area of ​​the locking block 21. Similarly, pulling the lever 18 causes the closing plate 19 to move to the right. When the partition 20 inside the liquid outlet chamber 17 causes the interlocking block 21 to come into contact with the locking groove 22 inside the liquid outlet chamber 17, the partition 20 can also be rotated to move the locking block 21, thereby locking the inner locking block 21 and the inner locking groove 22 together, thus preventing the lever 18 from moving. To prevent the closing plate 19 from not sealing properly, a sealing ring can be installed on the inside of the closing plate 19; A drain pipe 15 is installed at the bottom of the liquid outlet chamber 17, and a valve 16 is installed in the middle of the drain pipe 15. A steam outlet 23 is connected between the heating tank 9 and the liquid outlet chamber 17, and a valve 24 is installed in the middle of the steam outlet 23. like Figure 11 As shown, when sampling and testing are required during fermentation, the operating procedure is as follows, and the entire process will not interfere with the fermentation system inside tank 1): Unlocking and opening the closing plate: First, rotate the partition 20 at the outer end of the pull rod 18 to separate the outer locking block 21 from the outer locking groove 22, releasing the locking state of the pull rod 18; then slowly pull the pull rod 18 outward to move the closing plate 19 to the right side of the liquid outlet 17 until the closing plate 19 fully opens the connection between the liquid outlet 17 and the tank body 1; continue to pull the pull rod 18, and when the locking block 21 of the partition 20 inside the liquid outlet 17 moves into the inner locking groove 22, rotate the partition 20 to engage the locking block 21 with the inner locking groove 22, fixing the position of the pull rod 18; Liquid diversion and retention: After the closing plate 19 is opened, the fermentation liquid in the tank 1 (filtered by the slag-blocking mesh 14 and free of solid impurities) flows into the left space of the outlet chamber 17 through the connecting port and further into the bottom drain pipe 15; after the drain pipe 15 is filled with fermentation liquid, push the pull rod 18 in the opposite direction to first release the locking of the inner locking block 21 and the inner locking groove 22, and then push the pull rod 18 to move the closing plate 19 inward until the closing plate 19 closes the connecting port again; during this process, the closing plate 19 will push most of the fermentation liquid in the left space of the outlet chamber 17 back into the tank 1, leaving only a small amount of fermentation liquid in the drain pipe 15 (enough to meet the testing requirements), avoiding changes in the concentration and liquid level of the fermentation system in the tank 1 due to the large amount of fermentation liquid extracted; Sample collection: finally open the valve 16 in the middle of the drain pipe 15, the remaining fermentation broth in the pipe will flow out, and after collection with a sampling container, the composition detection (such as active ingredient content, microbial quantity, etc.) can be carried out, and after sampling is completed, the valve 16 is closed; Sample collection: finally open the valve 16 in the middle of the drain pipe 15, the remaining fermentation broth in the pipe will flow out, and after collection with a sampling container, the composition detection (such as active ingredient content, microbial quantity, etc.) can be carried out, and after sampling is completed, the valve 16 is closed; Double-path isolation design: the liquid warehouse 17 can form two independent flow paths through the position adjustment of the closing plate 19 and the partition plate 20, and the two paths do not interfere with each other when in use: a liquid flow path (sampling path): when the pull rod 18 is pulled to the inside locking state, the partition plate 20 in the liquid warehouse 17 moves to the right side of the liquid warehouse 17, and the closing plate 19 is located at the right side of the connection between the liquid warehouse 17 and the drain pipe 15, at this time the flow path is 'inside the tank body 1→ below the slag blocking net 14→ left side space of the liquid warehouse 17→ inside the drain pipe 15', which is only used for the flow guide and sampling of fermentation broth; b steam flow path (cleaning path): when the pull rod 18 is pushed to the outside locking state, the closing plate 19 moves to the left to close the communication port between the tank body 1 and the liquid warehouse 17, at this time the flow path is 'heating tank 9→ steam outlet 23→ internal space of the liquid warehouse 17→ drain pipe 15→ outside', which is only used for the circulation of high-temperature steam and the cleaning of the assembly; The two paths are sealed and isolated by the closing plate 19 and positioned by the partition plate 20, which ensures that there is no steam mixed in during sampling and no liquid backflow during cleaning, and guarantees the accuracy and safety of the operation; The lower side of the tank body 1 is provided with a slag outlet 26, and the slag outlet 26 is located above the slag blocking net 14. When fermentation is completed, the sealing door of the slag outlet 26 is opened, and due to the isolation effect of the slag blocking net 14, the medicinal material residues (or medicinal materials that have not been completely fermented) are all retained above the slag blocking net 14 and can be directly taken out from the slag outlet 26. At the same time, the slag blocking net 14 can effectively block the residues from entering the liquid warehouse 17 and the drain pipe 15 below, completely avoiding the blockage of the sampling channel; The bottom of the tank body 1 is provided with a liquid outlet 25, which is mainly used for liquid discharge in two scenarios: one is to discharge cleaning wastewater (such as wastewater after bubble cleaning, wastewater after final washing) in the cleaning process; the other is to discharge all fermentation liquid after fermentation (if the fermentation liquid needs to be processed in batches); the pipe diameter of the liquid outlet 25 is larger than that of the liquid discharge pipe 15, so that rapid liquid discharge can be realized and the operation efficiency is improved; The top of the tank body 1 is provided with a feeding port 27. Before starting the cleaning or fermentation process, the sealing cover is opened, and traditional Chinese medicinal materials, cleaning water or auxiliary materials (such as strains, nutrients) required for fermentation can be added to the tank body 1 through the feeding port 27; The outer side of the tank body 1 is provided with a liquid level pipe 28. The liquid level pipe 28 is made of transparent glass or plastic material, and the upper and lower ends thereof are in communication with the inside of the tank body 1 (the upper end is in communication with the upper space of the tank body 1, and the lower end is in communication with the space below the slag blocking net 14), which follows the principle of “communicator”. When liquid (cleaning water or fermentation liquid) is added to the tank body 1, the liquid level in the liquid level pipe 28 is consistent with the liquid level height in the tank body 1. The operator can directly observe the liquid volume through the liquid level pipe 28, so as to avoid excessive water overflow or insufficient water affecting the cleaning / fermentation effect when adding materials. The internal liquid state can be grasped without opening the tank body 1.

[0022] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the present application, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
