Traditional Chinese medicine granule granulating device and granulating method

Abstract

This invention provides a granulation device and method for traditional Chinese medicine (TCM) granules, relating to the field of TCM granulation. The TCM granulation device includes a frame, a pulverizing mechanism, a high-temperature extraction slurry assembly, and a dry mud granulation assembly, all fixedly installed within the frame. The pulverizing mechanism pulverizes the TCM and transfers it to the high-temperature extraction slurry assembly, where it heats and extracts the medicinal liquid. Finally, the liquid is pushed by steam to the dry mud granulation assembly for drying and granulation. This TCM granulation device and method eliminate the need for additional removal of the TCM powder. The steam not only heats the powder but also forms a medicinal liquid. Furthermore, the steam utilizes its high temperature and pressure to propel the medicinal liquid to the next stage, preventing contact between the liquid and external pumping components, thus reducing the probability of contamination. The steam continuously extracts components from the medicinal liquid, saving energy used in decocting TCM. The medicinal liquid is never removed and remains free from contact with the external environment.

Their main characteristics are that they can be swallowed directly or dissolved in water for drinking, making them convenient to use and carry, and they dissolve and absorb relatively quickly. However, existing traditional Chinese medicine granulation equipment has a relatively simple structure, requiring frequent material movement during production, leading to poor production efficiency and potential material contamination, which is detrimental to meeting the high-quality production requirements of traditional Chinese medicine granules.

[0030] A method for granulating traditional Chinese medicine includes the following steps:

[0031] Step 1: First, add water to the prepared Chinese medicine and then put it into the pulverizing device to achieve preliminary crushing;

[0032] Step 2: The crushed slurry enters the high-temperature extraction slurry assembly and is treated with steam;

[0034] Step 4: Infuse hot dry air into the dry granulation unit to dry it into a granule state and then knead it.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The Chinese medicine granulation device and granulation method allow for direct extraction of Chinese medicine powder using steam after grinding, eliminating the need to remove the powder. The steam not only heats the powder but also forms a liquid. Furthermore, the high temperature and pressure of the steam propel the liquid to the next stage, preventing it from contacting external pumping components and further reducing the probability of contamination.

[0037] 2. The Chinese medicine granulation device and granulation method, by setting a high-temperature extraction pharmaceutical slurry component, when steam is introduced into the high-temperature extraction pharmaceutical slurry component, the ground medicine mud can be extracted by steam in a mixed form. The steam can have a larger contact area with the medicine liquid. After the steam fully contacts the medicine mud, a relatively viscous medicine liquid can be formed. At this time, the components in the medicine liquid have been basically extracted by steam, which is convenient for subsequent kneading.

[0038] 3. The granulation device and method for Chinese medicine granules, by setting up a dry mud granulation component, can achieve a high-temperature sterilization effect in the early stage by introducing steam into the mud granulation component. The steam can also push the liquid medicine to the high-pressure kettle, where the liquid medicine is dried into mud by using dry hot air, and then kneaded into strips. In this series of processes, the steam is constantly extracting the components in the liquid medicine until it is finally dried. Therefore, it can save energy for boiling Chinese medicine, and the liquid medicine is not removed throughout the process, and the liquid medicine will not come into contact with the external environment.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] like Figure 1-11 As shown, a traditional Chinese medicine granulation device and granulation method includes a frame 1, a pulverizing mechanism 2, a high-temperature extraction pharmaceutical slurry assembly 3, and a dry mud granulation assembly 4, all of which are fixedly installed in the frame 1.

[0053] The pulverizing mechanism 2 pulverizes the Chinese medicine and transfers it to the high-temperature extraction pharmaceutical slurry component 3, which can heat up and extract the medicinal liquid. Finally, it is pushed by steam to the dry mud granulation component 4 for drying and granulation.

[0054] The high-temperature extraction pharmaceutical slurry assembly 3 includes an expansion chamber 301, and the pulverizing mechanism 2 is connected to the interior of the expansion chamber 301. The inner bottom wall of the expansion chamber 301 is provided with a through hole.

[0055] A hydraulic motor 302 is mounted on the expansion cavity 301 and is slidably connected to it vertically.

[0056] Hydraulic cylinder 303 is fixed on expansion chamber 301, and its output end is connected to hydraulic motor 302;

[0057] The bottom cavity 304 is fixed to the bottom of the expansion cavity 301, and the internal cavities of the two are connected through a through hole;

[0058] The cylinder body 305 is fixed at the lower end of the bottom cavity 304, and the internal cavities of the two are connected. The bottom end of the cylinder body 305 is connected to the dry mud granulation component 4.

[0059] The sealing tube 306 is located inside the expansion cavity 301, and its upper end is fixed to the top wall of the expansion cavity 301;

[0060] The rotating shaft 307 is located inside the sealing tube 306. Its upper end is fixed to the output end of the hydraulic motor 302, and its lower end extends into the bottom cavity 304.

[0061] The rotating wheel 308 is located on the inner bottom wall of the expansion cavity 301, below the sealing tube 306, and the diameter of the rotating wheel 308 is smaller than that of the through hole;

[0062] The piston 309 is angled and has a one-way valve body mounted on it. It is fixed to the end of the rotating shaft 307 away from the hydraulic motor 302. The rotating shaft 307 passes through the rotating wheel 308 in the middle and is slidably connected to it. The rotation of the rotating shaft 307 can drive the rotating wheel 308 to rotate. A spring 310 is fixed inside the sealing tube 306 on the rotating wheel 308. The spring 310 is sleeved on the rotating shaft 307 and its upper end is fixed to the outer wall of the rotating shaft 307.

[0063] The impeller 311 has a ring-shaped structure, is fixedly sleeved on the outside of the rotating wheel 308, and contacts the inner bottom wall of the expansion cavity 301.

[0064] Frame 1 supports all components. Hydraulic motor 302 uses a hydraulic drive device to provide power and control, and can output hydraulic pressure as high torque rotation. Sealing tube 306 can effectively prevent Chinese medicine slurry from entering precision parts. The piston 309 is covered with a rubber ring. The one-way valve on piston 309 is closed when piston 309 moves down and opens when it moves up. A toothed sleeve is fixedly fitted at the connection between rotating shaft 307 and rotating wheel 308. Rotating wheel 308 has a toothed groove that runs vertically through the toothed sleeve at the position corresponding to the toothed sleeve. The toothed sleeve is inserted into the toothed groove and cooperates with it. The length of the toothed sleeve is longer than the toothed groove. Therefore, when the toothed sleeve moves downward in the toothed groove, it can still drive the rotating wheel 308 to rotate through the toothed groove.

[0065] The expansion cavity 301 has a downward-facing and expanding structure. A conical ring 312 is fixedly installed on its inner bottom wall. The upper end of the conical ring 312 is a concave and contracting conical structure, and the impeller 311 is located in its inner ring.

[0066] The herbal slurry and debris falling on the conical ring 312 can flow into the central through hole by gravity. When the impeller 311 rotates, the flowing slurry is ground and can achieve full contact with the steam.

[0067] The impeller 311 has a wave-shaped ring structure, with arc-shaped protrusions and arc-shaped grooves on both its upper and lower surfaces.

[0068] The wavy structure allows the slurry to pass through the groove at its bottom, and during the passage, steam bursts out from below, which can extract the components from the Chinese herbal medicine slurry.

[0069] The dry sludge granulation component 4 includes a guide tube 401, which is obliquely arranged. Its lower end is connected to the bottom of the cylinder 305 via a bend A402. The middle part of the guide tube 401 has an expansion structure, and a steam pipe 403 connected to its interior is fixedly installed on one side.

[0070] It also includes a high pressure vessel 404. The upper end of the guide pipe 401 is connected to the bottom of the high pressure vessel 404 via a bend pipe B405 and communicates with its interior. A controllable one-way valve is installed at the bend pipe B405. A granulation sludge discharge pipe 406 is installed at the bottom of the high pressure vessel 404. A water discharge pipe 407 is installed on the top wall of the high pressure vessel 404. An exhaust pipe 408 is installed on the upper side of the high pressure vessel 404.

[0071] A hollow tube 409 is inserted longitudinally into a high-pressure vessel 404 and rotatably connected to its center position. A pressure relief valve is installed at its upper end. A kneading assembly A410 and a kneading assembly B411 are fixedly installed at one end of the hollow tube 409 inside the high-pressure vessel 404. The kneading assembly A410 is located above the kneading assembly B411.

[0072] The dry hot air pipe 412 is connected to one end of the hollow pipe 409 located on the bottom surface of the autoclave 404. Steam can enter the kneading assembly A410 and the kneading assembly B411 through the dry hot air pipe 412 and the hollow pipe 409.

[0073] The rocker arm 413 is fixed to the end of the hollow tube 409 above the autoclave 404;

[0074] The cylinder 414 has its fixed end hinged to the side wall of the autoclave 404, and its telescopic end hinged to the end of the rocker arm 413 away from the hollow tube 409.

[0075] A valve is provided at the upper end of the bent pipe 402. The upward-facing guide pipe 401 allows the slurry to stack during pushing, facilitating continued steam extraction during this process. Valves are provided on the granulation mud discharge pipe 406, the exhaust pipe 408, and the water discharge pipe 407. The exhaust pipe 408 is used to discharge steam, the water discharge pipe 407 is used to clean the Chinese medicine residue inside the high-pressure kettle 404, and the granulation mud discharge pipe 406 is used to discharge the kneaded mud strips. The steam pipe 403 blows a small amount of steam into the guide pipe 401, mainly to foam the Chinese medicine slurry, enhance its fluidity, and increase the temperature to achieve uniform extraction of components and avoid local high temperatures. The dry hot air pipe 412 is controlled by an electromagnetic valve to intermittently fill the high-pressure kettle 404 with dry hot air, which is used to discharge the internal water vapor after the extraction is completed, reducing the water content inside the Chinese medicine liquid. When the controllable one-way valve is activated, the pumping action of piston 309 allows the slurry to slowly enter the high-pressure vessel 404, and the pressure will gradually increase. At this time, the pumped-in steam will improve the extraction efficiency.

[0076] The high-pressure autoclave 404 is provided with multiple convex rings 415, and both the kneading assembly A410 and the kneading assembly B411 are provided with multiple convex rings 415. The convex rings 415 are used to clamp and support the kneading assembly A410 and the kneading assembly B411.

[0077] The kneading assembly A410 includes a hollow disc A4101 and a grinding column 4102. The hollow disc A4101 is fixed on the hollow tube 409, and the internal cavities of the two are connected. The outer wall of the disc has multiple vertically penetrating notches A4103. The inner wall of the notches A4103 has spray holes A4104 that communicate with the interior of the hollow disc A4101. The number of grinding columns 4102 corresponds to the number of notches A4103, and they are located within the corresponding notches A4103. The grinding columns 4102 are located between two adjacent convex rings 415. There are gaps between the outer circle of the grinding column 4102, the side wall of the hollow disc A4101, and the inner wall of the autoclave 404.

[0078] When the hollow disc A4101 rotates, it drives the grinding column 4102 to rotate and grind the slurry. Meanwhile, hot dry air is sprayed out from the nozzle A4104 and combines with the Chinese medicine slurry. When kneading the Chinese medicine slurry, it can further remove the internal moisture, making it easier for the Chinese medicine slurry to become a paste. During this process, the Chinese medicine slurry gradually becomes viscous and eventually becomes a paste. Under continuous rotation, the Chinese medicine paste is gradually crushed and kneaded into medicinal strips.

[0079] The kneading assembly B411 includes a hollow disc B4111 and a grinding block 4112. The hollow disc B4111 is fixed on the hollow tube 409, and the internal cavities of the two are connected. The outer wall of the disc has multiple through-holes B4113. Each inner wall of the through-holes B4113 has multiple spray holes B4114 that communicate with the interior of the hollow disc A4101. The number of grinding blocks 4112 corresponds to the number of through-holes B4113, and they are located within the corresponding through-holes B4113. The grinding blocks 4112 are located between two adjacent convex rings 415. There are gaps between the outer circle of the grinding blocks 4112, the side wall of the hollow disc B4111, and the inner wall of the autoclave 404.

[0080] After the herbal paste becomes viscous, it will gradually solidify under the continuous rotation of hollow discs A4101 and B4111, eventually becoming strip-shaped herbal paste.

[0081] The crushing mechanism 2 includes a gourd cavity 201, an inclined tube 202, a processing cavity 203, a drive shaft 204, a motor 205, and an eccentric grinding wheel 206. The processing cavity 203 is fixed to and connected to the bottom end of the gourd cavity 201. One end of the inclined tube 202 is connected to the side of the processing cavity 203, and the other end of the inclined tube 202 is connected to the upper side wall of the expansion cavity 301. The inclined tube 202 connects the processing cavity 203 and the expansion cavity 301 respectively. The eccentric grinding wheel 206 is located inside the processing cavity 203. The motor 205 is fixed at the bottom of the processing cavity 203. The drive shaft 204 is longitudinally inserted into the gourd cavity 201 and the processing cavity 203 and is connected to the output shaft of the motor 205. The drive shaft 204 is fixedly inserted through the eccentric position of the eccentric grinding wheel 206. One side of the eccentric grinding wheel 206 is engaged with the inner wall of the processing cavity 203.

[0082] It also includes two sets of cutting blades 207, both of which are fixedly sleeved on the drive shaft 204 and located inside the hoist cavity 201.

[0083] The crushing mechanism 2 is used to crush the Chinese medicinal materials in the early stage. Water is added during the crushing process to make the powder of Chinese medicinal materials flowable and easy to transfer to the next process. The eccentric grinding wheel 206 can squeeze the liquid of Chinese medicinal materials during the rotation process and bring it into the inclined tube 202. In addition, steam will also enter the crushing mechanism 2 through the inclined tube 202 in the early stage to preheat the Chinese medicinal materials in the early stage, so that the liquid of Chinese medicinal materials falling into the inclined tube 202 is already at a high temperature.

[0084] The gourd cavity 201 is composed of two spherical structures connected together. The diameter of the connecting part in the middle is smaller than that of the spherical structures. The upper end of the gourd cavity 201 is an open structure. The two sets of cutting blades 207 are respectively located in the two spherical structures. The middle position of the drive shaft 204 is supported by the connecting part.

[0085] The cutting blade 207 is used to cut the fibers of Chinese medicinal materials, and the gourd cavity 201 can facilitate the better crushing of medicinal materials into medicinal paste. When water is added from above, the centrifugal force of the cutting blade 207 will also cause the water to be thrown into the gourd cavity 201, so there will be no problem of water sticking to the wall.

[0086] A method for granulating traditional Chinese medicine includes the following steps:

[0087] Step 1: First, add water to the prepared Chinese medicine and then put it into the pulverizing device 2 to achieve preliminary crushing;

[0088] Step 2: The crushed slurry enters the high-temperature extraction slurry assembly 3 and is treated with steam;

[0089] Step 3: Change the direction of the steam to push the high-temperature treated liquid into the dry mud granulation component 4;

[0090] Step 4: Infuse hot dry air into the dry granulation assembly 4 to dry it into a granule state and then knead it.
