Description

Technical Field

[0001] This utility model relates to a processing device for Polygonum multiflorum, belonging to the field of traditional Chinese medicine pharmaceutical equipment. Background Technology

[0002] Polygonum multiflorum Thunb., the dried tuberous root of the Polygonum multiflorum plant, is a commonly used traditional Chinese medicine. However, the raw product has a certain degree of toxicity, mainly due to anthraquinone compounds such as rhein and chrysophanol. Excessive or improper use of these components may irritate the gastrointestinal tract, causing symptoms such as borborygmus, nausea, abdominal pain, diarrhea, and vomiting. In extreme cases, it may lead to severe reactions such as paroxysmal tonic-clonic seizures, restlessness, convulsions, or even respiratory paralysis.

[0003] To reduce the toxicity and side effects of Polygonum multiflorum (He Shou Wu), it is usually processed to reduce toxicity and enhance efficacy, such as processing with black beans or alcohol. These processing methods can significantly reduce the toxic components in Polygonum multiflorum while retaining its medicinal properties. Processed Polygonum multiflorum is believed to have the effects of darkening hair, tonifying the liver and kidneys, nourishing menstruation and blood, strengthening muscles and bones, and clearing turbidity and lowering lipids.

[0004] Polygonum multiflorum (He Shou Wu) has been used medicinally since the Tang and Song dynasties, with simple processing methods such as boiling, steaming, and steaming with black beans. The Song dynasty medical text *Taiping Shenghui Fang* pioneered the complex processing method of "nine steamings and nine sun-dryings" for Polygonum multiflorum. Famous medical works of the same period, such as *Bencao Tujing* and *Zheng Lei Bencao*, also recorded this method. During the Ming and Qing dynasties, more than twenty classic medical works, including *Bencao Gangmu*, *Jingyue Quanshu*, and *Lei Gong Paozhi Yaoxing Jie*, regarded the nine-steaming and nine-drying process as the mainstream method for processing Polygonum multiflorum, with most of these processes using black beans as an auxiliary processing ingredient. After the 1990 edition of the *Chinese Pharmacopoeia* was published, the primary method for processing Polygonum multiflorum was soaking the medicinal material in black bean juice followed by steaming. The current pharmacopoeia lists the steaming method for Polygonum multiflorum as follows: Take raw Polygonum multiflorum slices or pieces, mix them with black bean juice to moisten them, place them in a non-iron steaming container, seal it, and steam until the juice is absorbed and the medicine turns brownish-brown. Then take it out and dry it.

[0005] Current processing techniques for Polygonum multiflorum involve placing Polygonum multiflorum pieces in a container, adding black bean juice and stirring, then transferring them to a steaming and simmering tank, followed by drying using a drying device. This method of stirring before transferring to the steaming tank results in the black bean juice remaining at the bottom of the container, making it difficult for the Polygonum multiflorum to absorb the juice evenly. This may have the following adverse effects: ① Uneven efficacy: Because the black bean juice is not evenly distributed on the surface of the Polygonum multiflorum, some pieces may not fully absorb the active ingredients, leading to uneven efficacy and affecting therapeutic effects; ② Waste of resources: The black bean juice that is not fully absorbed by the Polygonum multiflorum is wasted, increasing processing costs and wasting valuable medicinal resources. ③ Affects the quality of medicinal materials: Uneven absorption may lead to uneven distribution of internal components of Polygonum multiflorum, affecting its overall quality; in addition, some Polygonum multiflorum that has not absorbed black bean juice may have a raw and astringent taste due to insufficient processing, reducing the palatability of the medicinal materials; ④ Increases the difficulty of operation: In order to ensure that Polygonum multiflorum absorbs black bean juice evenly, operators need to stir it repeatedly, which not only increases the labor intensity, but may also damage the medicinal materials due to improper operation.

[0006] Furthermore, the process of transferring the mixed Polygonum multiflorum to the steaming tank, as part of the processing procedure, is cumbersome in practice. This not only increases the difficulty of operation but may also adversely affect the quality of the medicinal material. During the transfer, the Polygonum multiflorum may come into contact with the external environment, increasing the risk of contamination. Especially under unsuitable conditions such as humidity and temperature, the medicinal material is more susceptible to microbial contamination, leading to processing failure or spoilage. The cumbersome transfer steps not only increase processing time but may also require repetition due to improper operation, thereby reducing the overall production efficiency of the processing procedure. Utility Model Content

[0007] In view of the shortcomings of existing Polygonum multiflorum processing technology, the technical problem to be solved by this utility model is to provide a new Polygonum multiflorum processing equipment.

[0008] This utility model of Polygonum multiflorum processing equipment is achieved through the following technical solutions:

[0009] A processing device for Polygonum multiflorum mainly consists of a tank 1, a hanging basket 2, a spraying system 3, a hydraulic device 4, a condenser 5, a circulation pipeline 6, and a pump set 7. Its special feature is that:

[0010] The spraying system 3 is located at the upper right end of the tank 1 and is connected to the bottom of the tank 1 via the circulation pipe 6 and the pump group 7. Its structure includes a spray head 31, a flow rate controller 32, a storage tank 33, and a liquid inlet 34.

[0011] The basket 2 is placed inside the tank 1, and the hydraulic device 4 is located at the top of the tank 1;

[0012] The condenser 5 is located at the top inside the tank 1.

[0013] In this invention, multiple baskets 2 can be placed inside the tank 1, and the bottom of the baskets 2 has evenly distributed round holes of equal diameter.

[0014] An inlet valve 12 is provided at the connection between the circulation pipe 6 and the bottom of the tank 1, and an outlet valve 13 is provided at the connection between the circulation pipe 6 and the top of the tank 1. A jacket 8 is provided on the side wall of the tank 1, with a steam inlet valve 9 at the lower end and a steam outlet valve 10 at the upper end. An exhaust valve 11 is provided on the top of the tank 1.

[0015] Specifically, during the processing of Polygonum multiflorum, the cleaned Polygonum multiflorum is placed in multiple hanging baskets 2, which are then suspended to the bottom of the steaming tank 1 and stacked sequentially. Black bean juice is transferred to a storage tank 33. The inlet valve 12 at the top and the outlet valve 13 at the bottom of the circulation pipe are opened, and the spray system 3 is turned on. The flow rate controller 32 controls the flow rate of the black bean juice, which is then evenly sprayed onto the Polygonum multiflorum through nozzles 31. The black bean juice flows down through the round holes of the hanging baskets 2 placed from top to bottom, ensuring that the Polygonum multiflorum in each layer of baskets is fully moistened. After the black bean juice is absorbed, the spray system 3 is turned off. Steam is introduced through the steam inlet valve 9 to carry out the steaming and simmering process of Polygonum multiflorum. Near the end of the processing, the spray system 3 is turned on to evenly spray the remaining black bean juice at the bottom of the tank onto the medicinal material, and the steaming and simmering process continues. After processing, open the tank 1, lift the basket 2 and move it to an open drying oven to dry, thus obtaining processed Polygonum multiflorum.

[0016] Based on long-term operational practice and a deep understanding of the processing technology and equipment for Polygonum multiflorum, the inventors of this utility model have innovatively designed and expanded the functions of existing processing equipment, setting up new structures such as "spray system 3", "circulation pipe 6", and "pump group 7" to solve the current technical problems of Polygonum multiflorum. By setting up spray system 3, black bean juice is stored in storage tank 33 and sprayed evenly onto Polygonum multiflorum through flow controller 32 and nozzle 31. At the same time, black bean juice flows down the circular holes of hanging basket 2 placed from top to bottom, ensuring that the Polygonum multiflorum in each layer of hanging basket 2 is fully moistened, solving the problem of uneven mixing of Polygonum multiflorum. At the same time, the black bean juice at the bottom of the tank enters storage tank 33 through circulation pipe 6 and sprays the medicinal material again, ensuring that black bean juice does not remain at the bottom of the tank. This application places the hanging basket 2 for placing Polygonum multiflorum in steaming tank 1, reducing the process of transferring the mixed Polygonum multiflorum to steaming tank.

[0017] This utility model is scientifically designed and produces significant technical effects. Compared with existing conventional equipment for processing Polygonum multiflorum, it has the following substantial features and advancements:

[0018] 1. This utility model eliminates the need to place Polygonum multiflorum in a container, add black bean juice, stir, and then transfer the mixed Polygonum multiflorum to a steaming tank, thus saving on the operation process and production costs.

[0019] 2. By setting up a spray system, this utility model can make the Polygonum multiflorum absorb black bean juice evenly, which improves the processing efficiency and is easy to operate, making it suitable for industrial production.

[0020] 3. The processed Polygonum multiflorum prepared by this invention has stable quality, reduced toxicity and increased efficacy, which significantly improves the quality of processed Polygonum multiflorum and enhances its clinical value. Attached Figure Description

[0028] Example 1: Structure and Operation Method of Polygonum multiflorum Processing Equipment

[0029] As attached Figure 1As shown, the Polygonum multiflorum processing equipment of this utility model mainly consists of a tank (1), a basket (2), a spray system (3), a hydraulic device (4), a condenser (5), a circulation pipe (6), and a pump group (7). The difference is that the spray system (3) is located at the upper right end of the tank (1) and is connected to the bottom of the tank (1) through the circulation pipe (6) and the pump group (7). Its structure includes a nozzle (31), a flow rate controller (32), a storage tank (33), and a liquid inlet (34). The basket (2) is placed inside the tank (1), and the hydraulic device (4) is located at the top of the tank (1). The condenser (5) is located at the top inside the tank (1).

[0030] Multiple baskets (2) can be placed inside the tank (1), and the bottom of each basket (2) has evenly distributed circular holes of equal diameter. An inlet valve (12) is provided at the connection between the circulation pipe (6) and the bottom of the tank (1), and an outlet valve (13) is provided at the connection between the circulation pipe (6) and the top of the tank (1). A jacket (8) is provided on the side wall of the tank (1), with an inlet valve (9) at the lower end of the jacket (8) and an outlet valve (10) at the upper end. An exhaust valve (11) is provided on the top of the tank (1).

[0031] Specifically, during the processing of Polygonum multiflorum, the cleaned Polygonum multiflorum is placed in multiple hanging baskets 2, which are then suspended to the bottom of the steaming tank 1 and stacked sequentially. Black bean juice is transferred to a storage tank 33. The inlet valve 12 at the top and the outlet valve 13 at the bottom of the circulation pipe are opened, and the spray system 3 is turned on. The flow rate controller 32 controls the flow rate of the black bean juice, which is then evenly sprayed onto the Polygonum multiflorum through nozzles 31. The black bean juice flows down through the round holes of the hanging baskets 2 placed from top to bottom, ensuring that the Polygonum multiflorum in each layer of baskets is fully moistened. After the black bean juice is absorbed, the spray system 3 is turned off. Steam is introduced through the steam inlet valve 9 to carry out the steaming and simmering process of Polygonum multiflorum. Near the end of the processing, the spray system 3 is turned on to evenly spray the remaining black bean juice at the bottom of the tank onto the medicinal material, and the steaming and simmering process continues. After processing, open the tank 1, lift the basket 2 and move it to an open drying oven to dry, thus obtaining processed Polygonum multiflorum.

[0032] Example 2: Processing of Polygonum multiflorum using different equipment

[0033] The existing processing equipment group: 250kg of Polygonum multiflorum slices are placed in a container, black bean juice is added and stirred, then transferred to a steaming tank, steamed for 1 hour, simmered for 12 hours, steamed for another 6 hours, simmered for 2 hours, the steaming tank is opened, and the Polygonum multiflorum is transferred to an open drying oven for drying, thus obtaining processed Polygonum multiflorum. Three batches are steamed.

[0034] New processing equipment: Place 250kg of Polygonum multiflorum slices in a steaming tank, spray with black bean juice for 1 hour to thoroughly moisten. Steam for 1 hour, then let it sit for 12 hours. Change the position of the hanging basket, turn on the circulation system to continue spraying, steam for 6 hours, then let it sit for 2 hours. Open the steaming tank, lift the second hanging basket and move it to an open drying oven for drying to obtain processed Polygonum multiflorum. Three batches are steamed.

[0035] Table 1 Comparison of components in processed Polygonum multiflorum

[0036]

[0037]

[0038] Compared with Polygonum multiflorum prepared using existing equipment, the Polygonum multiflorum prepared according to this invention exhibits a significantly increased content of free anthraquinones and a significantly decreased content of stilbene glycosides (see Table 1 for details). The bound anthraquinones in the raw variety have a strong laxative effect; after processing, they are converted into free anthraquinones, thus reducing the laxative effect and enhancing the tonic effect. Stilbene glycosides increase the liver's susceptibility to emodinous components in Polygonum multiflorum. The Polygonum multiflorum prepared by this invention, when steamed, can significantly reduce the content of stilbene glycosides compared to existing equipment, thereby reducing the liver's sensitivity to the toxic components of Polygonum multiflorum and achieving the goal of reducing toxic side effects.
