Medicinal materials mainly come from plants, animals and minerals. They can be used as raw materials for traditional Chinese medicine or modern medicine after being processed by specific methods. Although medicinal materials contain a variety of chemical components, not all components have medicinal effects. Extraction can concentrate active ingredients, increase the bioavailability of drugs, and improve their activity and absorption rate in the human body.

[0003] The medicinal material extraction device is a device used to extract effective ingredients from natural medicinal materials. It is used in the production and research of traditional Chinese medicine, plant essences, biological products, etc. Its main purpose is to improve the extraction efficiency and output quality. The medicinal material extraction device mainly includes an extraction tank, a heating device, a condenser and a filter. The extraction tank is the main body of the extraction process, in which the medicinal materials come into contact with the solvent to dissolve the effective ingredients. The heating device is used to improve the solvent's solubility and extraction efficiency. The condenser is used to cool the evaporated solvent back to a liquid form for recycling. The filter is used to remove impurities to make the extract purer.

[0019] An extraction process and preparation method of a Chinese herbal medicine composition, comprising the following steps:

[0020] S1: The medicinal raw materials to be extracted are placed at the feed port, and then the medicinal raw materials fall into the inside of the feed pipe. The medicinal raw materials can be transported by the rotation of the auger rod. Smaller medicinal raw material particles are discharged from the inside of the feed pipe in advance through the mesh during the transportation process. The smaller medicinal raw material particles are temporarily stored in the storage block, and the larger medicinal raw material particles continue to be transported along the feed pipe and fall into the inside of the extraction tank;

[0021] S2: The auger can drive the lower blade to rotate during the process of conveying the medicinal material particles. The lower blade can smooth the larger particles that fall into the extraction tank first through the rotation, and then discharge the smaller medicinal material particles temporarily stored in the storage block into the extraction tank through the discharge port;

[0022] S3: adding a proper amount of soaking liquid into the extraction tank through the water injection component, and evenly heating the extraction tank with steam through the heating component. When the extraction tank is heated, the soaking liquid can generate steam due to heat, and the steam generated by the soaking liquid can be condensed and diverted through the reflux component, and then returned to the extraction tank to maintain circulating humidity;

[0023] S4: After the extraction of medicinal materials is completed, the medicinal liquid inside the extraction tank is extracted through the filtering component, filtered and stored. After the extraction of the medicinal liquid is completed, the bottom cover is driven to flip through the flipping component. After the bottom cover is flipped, the medicinal material residue inside the extraction tank can be discharged. After the medicinal material residue inside the extraction tank is discharged, the inside of the extraction tank can be cleaned through the water injection component.

[0024] In summary, the technical effects and advantages of the present invention are as follows:

[0025] 1. In the present invention, quantitative transportation of medicinal raw materials can be achieved through the auger rod. During the transportation process, fine particles will fall into the storage block through the mesh for temporary storage, while larger particles will fall into the access tank first. With the driving of the auger rod, the lower blade rotates to smooth the larger particles that fall into the extraction tank first. Then, the fine particles in the storage block are discharged into the extraction tank through the discharge port, ensuring that the fine particles are located at the top and the larger particles are located at the bottom. This arrangement can prevent the fine particles from settling to the bottom during long-term soaking, thereby avoiding agglomeration or blockage during processing. At the same time, the larger particles located at the bottom help to maintain stability during the soaking process, which is beneficial to the uniform penetration and extraction of medicinal materials.

[0026] 2. In the present invention, after the driving motor is started, the rotating shaft is able to rotate. The rotation of the rotating shaft further drives the upper blades to rotate through the coordinated action of the belt pulley and the thick shaft. The rotation of the upper blades acts on the fine particles that subsequently enter the extraction tank to smooth them, thereby avoiding particle accumulation and the generation of gaps. This ensures that the medicinal materials are highly evenly distributed in the extraction tank, promotes the uniform flow of the solvent, improves the efficiency and uniformity of the medicinal material extraction, and ensures the quality of the final extraction product.

[0027] 3. In the present invention, when the device is heated for extraction, steam containing liquid medicine is generated due to the increase in internal temperature. The steam can flow into the condenser through the exhaust port and the exhaust pipe, and the gas can be condensed into liquid through the condenser. Then, the steam flows into the cooler through the connecting pipe to cool the high-temperature liquid. After the liquid is cooled, it flows into the oil separator through the guide pipe to divert and extract the liquid. The extracted liquid flows into the extraction tank again through the reflux pipe for recycling.

[0028] 4. In the present invention, starting the electric telescopic rod can drive the rotating plate to rotate, and the rotating plate can drive the bottom cover to rotate by rotating. During the rotation process, the rotating block and the fixed plate cooperate with each other to make it more stable. The bottom cover can discharge the medicinal material residues inside the extraction tank after rotation. After the drug residues are discharged, the cleaning liquid can be processed and discharged into the annular water pipe through the water injection pipe, and then the liquid inside the annular water pipe is sprayed out through the nozzle to clean the extraction tank, thereby making the entire slag discharge and cleaning process highly automated, reducing manual intervention and improving overall work efficiency.

[0068] An extraction process and preparation method of a Chinese herbal medicine composition, comprising the following steps:

[0069] S1: The medicinal material to be extracted is placed at the feed port 21, and then the medicinal material falls into the feed pipe 22. The medicinal material can be transported by the rotation of the auger 28. Smaller medicinal material particles are discharged from the feed pipe 22 in advance through the mesh 23 during the transportation process. The smaller medicinal material particles are temporarily stored in the storage block 24, and the larger medicinal material particles continue to be transported along the feed pipe 22 and fall into the extraction tank 1.

[0070] S2: The auger rod 28 can drive the lower blade 32 to rotate during the process of conveying the medicinal material particles. The lower blade 32 can smooth the larger particles that fall into the extraction tank 1 first through the rotation, and then discharge the smaller medicinal material particles temporarily stored in the storage block 24 into the extraction tank 1 through the discharge port 25;

[0071] S3: adding a proper amount of soaking liquid into the extraction tank 1 through the water injection component 5, and evenly heating the extraction tank 1 with steam through the heating component 6. When the extraction tank 1 is heated, the soaking liquid can generate steam due to the heat, and the steam generated by the soaking liquid can be condensed and diverted through the reflux component 8, and then returned to the extraction tank 1 to maintain the circulating humidity;

[0072] S4: After the extraction of medicinal materials is completed, the medicinal liquid inside the extraction tank 1 is extracted through the filtering component 9, and the liquid is filtered and stored. After the extraction of the medicinal liquid is completed, the bottom cover 11 is driven to flip through the flipping component 7. After the bottom cover 11 is flipped, the medicinal material residue inside the extraction tank 1 can be discharged. After the medicinal material residue inside the extraction tank 1 is discharged, the inside of the extraction tank 1 can be cleaned through the water injection component 5.

[0073] Working principle of the present invention: the raw material of medicinal material particles to be extracted is placed in the feed port 21, and the raw material of medicinal material particles gradually falls into the inside of the feed pipe 22. The feed motor 27 is started to drive the auger rod 28 to rotate. The auger rod 28 can transport the medicinal material in the feed pipe 22 by rotating. During the transportation process, smaller raw material particles can flow into the storage block 24 through the mesh 23, and larger particles are transported to the inside of the extraction tank 1 through the feed pipe 22. The auger rod 28 can drive the active bevel gear 29 to rotate during the rotation process. The active bevel gear 29 can drive the passive bevel gear 30 to rotate by rotating. The passive bevel gear 30 can drive the thin shaft 31 to rotate by rotating. The thin shaft 31 can drive the lower blade 32 by rotating. The lower blade 32 rotates, and the rotation can make the larger medicinal material particles flattened on the bottom side of the extraction tank 1. Then, the discharge port 25 is opened by the electric valve switch 26. After the discharge port 25 is opened, the medicinal material particles in the storage block 24 can be discharged into the extraction tank 1. The driving motor 34 is started to drive the rotating shaft 35 to rotate. The rotating shaft 35 can drive the belt pulley 36 to operate by rotating. The belt pulley 36 can drive the thick shaft 37 to rotate by operating. The thick shaft 37 can drive the upper blade 38 to rotate by operating. The upper blade 38 can smooth the smaller particles that enter the extraction tank 1 later by rotating, thereby promoting the uniform flow of the solvent and achieving a consistent extraction effect. The solution can be transported to the annular water pipe 51. The solution in the annular water pipe 52 is then uniformly injected into the extraction tank 1 through the nozzle 53. The steam in the steam pipe 61 can be transported to the extraction tank 1 through the control steam valve 62, thereby heating the extraction tank 1 to improve the solvent dissolving ability and extraction efficiency. During the heating process, the temperature of the extraction tank 1 is lower than the temperature of the steam, so that the steam produces a small amount of condensate, which can flow into the recovery tank 69 through the drain pipe 67. When the extraction tank 1 is heated, the solvent temperature rises and a large amount of solvent vapor is generated. The solvent vapor can flow into the condenser 83 through the exhaust port 81 and the exhaust pipe 82, and the solvent vapor is converted into a high-temperature liquid through the condenser 83. The high-temperature liquid can flow into the cooling tank 69 through the connecting pipe 84. The high-temperature liquid is cooled by the cooler 85, and the cooled liquid flows into the oil separator 87 through the guide pipe 86. The oil in the liquid can be separated by the oil separator 87. The separated liquid flows into the extraction tank 1 again through the reflux pipe 88. When the heating is completed, the steam valve 62 and the drain valve 68 are closed to stop heating the extraction tank 1. As the extraction of medicinal materials is completed, the extracted medicinal liquid in the extraction tank 1 is extracted into the filter 92 through the extraction pipe 91. The filter 92 is used to filter the medicinal liquid. Then, the filtered medicinal liquid is transported to the storage tank 94 through the discharge pipe 93 for storage. After the extraction of the medicinal liquid is completed, the electric telescopic rod 74 can drive the rotating plate 71 to rotate.The rotating plate 71 can drive the bottom cover 11 to rotate by rotating, and the bottom cover 11 can discharge the medicinal material residue from the inside of the extraction tank 1 after rotating. After discharge, water is injected into the extraction tank 1 through the water injection pipe 51 for cleaning.
