Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pharmaceutical engineering, especially to a closed traditional Chinese medicine extraction and concentration device. BACKGROUND

[0002] With the increasing demand for the quality and efficacy stability of traditional Chinese medicine products, and the increasing awareness of environmental protection and safety production, the traditional open traditional Chinese medicine extraction and concentration method gradually withdraws, and the closed traditional Chinese medicine extraction and concentration device emerges as the times require. It guarantees efficient, stable and clean traditional Chinese medicine extraction and concentration process with excellent sealing performance, precise temperature control and efficient recovery.

[0003] The closed traditional Chinese medicine extraction and concentration device mainly comprises a sealed tank body, a feeding port, a discharging port and a heating and cooling system. During operation, traditional Chinese medicinal materials enter the sealed tank through the feeding port. The heating and cooling system guarantees and promotes the dissolution of effective components of traditional Chinese medicines according to the principle of heat and mass transfer. The whole process is carried out in a closed environment to avoid pollution and efficiently realize the separation and enrichment of traditional Chinese medicine components, meeting the needs of pharmaceutical and natural product separation.

[0004] The existing closed traditional Chinese medicine extraction and concentration device plays an important role in the field of traditional Chinese medicine component extraction. The common pressurized heating or stirring means can indeed promote the full action of solvents and traditional Chinese medicinal materials according to the principle of physical and chemical, and then efficiently extract the effective components of traditional Chinese medicines to a certain extent. However, there is a lack of effective extrusion process in the pretreatment link of traditional Chinese medicinal materials, which makes most of the traditional Chinese medicinal materials simply rely on the penetration, heat conduction and stirring of solvents to release components. Many traditional Chinese medicinal materials have tough cell structures, and the effective components tightly combined and deeply hidden in the core of cells, such as some strong fat-soluble medicinal components tightly combined with intracellular macromolecules, are difficult to break through the cell wall and be fully released. This insufficient extraction directly leads to unsatisfactory yield of effective components in single extraction. At the same time, due to the low utilization rate of raw materials, more traditional Chinese medicinal materials have to be invested to achieve the predetermined yield, which undoubtedly greatly increases the production cost and seriously restricts the improvement of economic benefits of the whole traditional Chinese medicine extraction and concentration process, and brings many obstacles to the stability and optimization of product quality. Therefore, a closed traditional Chinese medicine extraction and concentration device is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0005] In order to make up for the above shortcomings, the utility model provides a closed traditional Chinese medicine extraction and concentration device, which aims to improve the problems of lack of extrusion in pretreatment, insufficient extraction, high cost and limited product quality in the prior art.

[0013] As further description of the above technical solution:

[0015] As further description of the above technical solution:

[0016] The middle part of the compression platform is uniformly provided with a plurality of filter holes, and the plurality of filter holes are arranged at the bottom of the high-pressure feed pipe.

[0019] As further description of the above technical solution:

[0020] The support block is fixedly connected between the frame and the control box, and the support block is also fixedly connected between the frame and the concentration barrel.

[0021] The utility model has the advantages of:

[0022] 1. In this utility model, by setting up a compression component, the hydraulic rod drives the pressing blocks to move in opposite directions, and the pressing teeth on the pressing blocks mesh with each other, which strongly compresses the Chinese herbal raw materials falling on the compression table. This pretreatment step can effectively destroy the tough cell structure of Chinese herbal materials, allowing those medicinal components that are originally hidden deep in the cell core, highly lipophilic and tightly bound to macromolecules to break through the constraints of the cell wall and be fully released. Compared with traditional devices that lack the compression process, this greatly improves the yield of effective components in a single extraction, reduces the amount of Chinese herbal raw materials that need to be added due to insufficient extraction, significantly reduces production costs, and provides a strong guarantee for the stable improvement of product quality.

[0023] 2. In this utility model, the temperature is precisely controlled by a temperature control component. The heat exchange pump delivers the heat exchange medium in the heat exchange tank to the heat exchange tube outside the concentration tank to heat the material. The temperature monitor monitors the temperature in real time and transmits the data to the PLC controller. The PLC controller precisely adjusts the heat exchange pump according to the set temperature to ensure that the concentration process is always carried out under suitable temperature conditions. This avoids the dissolution and stability of the effective components of traditional Chinese medicine due to excessively high or low temperatures, further improving product quality and ensuring the high efficiency and stability of traditional Chinese medicine extraction and concentration operations. It also meets the stringent requirements of pharmaceutical and natural product separation for temperature control of the concentration device. Attached Figure Description

[0030] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] With reference to Figure 1 and Figure 3 An embodiment provided by the present application is a closed traditional Chinese medicine extraction and concentration device, which comprises a frame 1, a concentration barrel 2 and a control box 4 are assembled in the middle of the frame 1, a heat exchange tank 3 is assembled on the outer side of the frame 1, a compression assembly 9 is arranged in the inside of the concentration barrel 2, a high-pressure feeding pipe 6 is arranged at the top of the concentration barrel 2, a liquid outlet pipe 7 is arranged in the middle of the concentration barrel 2, and a temperature control assembly 15 is arranged in the middle of the concentration barrel 2.

[0032] The compression assembly 9 comprises a compression table 10 which is fixedly connected to the inside of the concentration barrel 2, a pair of pressing blocks 12 are symmetrically arranged on the compression table 10, a hydraulic rod 11 is arranged in the middle of the concentration barrel 2, the pressing blocks 12 are fixedly connected to the output end of the hydraulic rod 11, a plurality of pressing teeth 13 are uniformly distributed on the end of the pressing blocks 12 away from the hydraulic rod 11, the pressing teeth 13 are fixedly connected to the side of the pair of pressing blocks 12 away from the hydraulic rod 11, the plurality of pressing teeth 13 are mutually meshed, a plurality of filter holes 14 are uniformly arranged in the middle of the compression table 10, and the plurality of filter holes 14 are arranged at the bottom of the high-pressure feeding pipe 6.

[0033] The traditional Chinese medicine raw materials are conveyed into the concentration barrel 2 through the high-pressure feeding pipe 6 and are stacked on the compression table 10. The hydraulic rod 11 is started to extend according to a predetermined program, so that the pair of pressing blocks 12 connected rigidly move towards each other. With the movement of the pressing blocks 12, the plurality of pressing teeth 13 uniformly distributed on the end of the pressing blocks 12 away from the hydraulic rod 11 gradually move close to each other and are tightly meshed, so as to continuously and strongly extrude the traditional Chinese medicine raw materials below. The extrusion force can effectively destroy the tough cell structure of the traditional Chinese medicine raw materials, so that the liquid containing effective components in the cells is squeezed out. The exuded liquid flows down smoothly under the traction of gravity, passes through the plurality of filter holes 14 arranged in the middle of the compression table 10, and is collected in the subsequent processing link. After the extrusion treatment, the texture of the traditional Chinese medicine raw materials becomes more loose, and the surface area is increased. This is not only beneficial to the subsequent full contact with the heating medium in the concentration barrel 2 to accelerate the dissolution of effective components and improve the extraction efficiency, but also can reduce the time and energy consumption required for subsequent concentration, so as to optimize the extraction and concentration efficiency of the whole traditional Chinese medicine concentration device from multiple aspects.

[0034] With reference to Figure 2 and Figure 4The temperature control assembly 15 comprises a heat exchange pump 16, which is assembled at the top of the heat exchange tank 3. The outside of the condensation barrel 2 is sleeved with a heat exchange pipe 17. The outside of the heat exchange pipe 17 is provided with a temperature monitor 18. The heat exchange tank 3 is provided with a PLC controller 19 away from the condensation barrel 2.

[0035] By starting the heat exchange pump 16 to work, strong suction is generated to extract the heat exchange medium pre-stored in the heat exchange tank 3 and accurately deliver it to the heat exchange pipe 17 sleeved outside the condensation barrel 2. At this time, the traditional Chinese medicine raw material accumulated in the condensation barrel 2 is continuously heated. The temperature monitor 18 senses the ambient temperature of the condensation barrel 2 and immediately transmits the collected temperature data to the PLC controller 19. The PLC controller 19 has set the appropriate temperature range in advance. Once the temperature data is received, the built-in comparison analysis program is quickly started to rigorously compare the measured temperature with the set temperature. If the measured temperature is lower than the lower limit of the set range, the PLC controller 19 will immediately issue an acceleration instruction to the heat exchange pump 16 to increase the delivery flow of the heat exchange medium and increase the heating power. Conversely, if the measured temperature is higher than the upper limit of the set range, the PLC controller 19 will issue a deceleration instruction to reduce the flow of the heat exchange medium to prevent overheating of the material. This cycle ensures that the condensation process is always stable at the appropriate temperature, which not only helps the full dissolution of traditional Chinese medicine active ingredients and prevents the destruction of ingredients or incomplete extraction due to improper temperature, but also improves the running stability of the entire device, reduces the risk of equipment failure caused by temperature out of control, and helps to ensure the efficiency and quality of the extraction and concentration of the traditional Chinese medicine condensation device.

[0036] With reference to Figure 1 and Figure 4 The heat exchange pipe 17 is fixedly connected to the output end of the heat exchange pump 16. The condensation barrel 2 and the heat exchange tank 3 are assembled with a return pipe 20. The frame 1 and the control box 4 are fixedly connected with a support block 21, and the support block 21 is also fixedly connected between the frame 1 and the condensation barrel 2.

[0037] By fixing the heat exchange pipe 17 to the output end of the heat exchange pump 16, when the heat exchange pump 16 operates to extract the heat exchange medium in the heat exchange tank 3, it can ensure that the medium flows stably and efficiently into the heat exchange pipe 17, providing heat for the material in the condensation barrel 2 without any obstruction. The medium that has been heated by the heat exchange pipe 17 returns to the heat exchange tank 3 through the return pipe 20 between the condensation barrel 2 and the heat exchange tank 3, realizing the recycling of the heat exchange medium, saving resources and ensuring the continuity of heating. The support blocks 21 fixedly connected between the frame 1 and the control box 4 and between the frame 1 and the condensation barrel 2 provide stable support for the entire device. During device operation, they effectively resist the influence of component vibration and shaking, improve production continuity, and effectively ensure the orderly progress of the extraction and concentration of the traditional Chinese medicine condensation device.

[0038] Working principle: first, the traditional Chinese medicine raw materials through high pressure feed pipe 6 into the concentration barrel 2, fall on the compression platform 10, through the hydraulic rod 11 start, push a pair of compression 12 opposite movement, compression 12 on the compression tooth 13 meshing, extruding the traditional Chinese medicine raw materials, to promote the liquid exuded, exuded liquid through the compression platform 10 on the filter hole 14 downward flow.

[0039] Secondly, in the concentration process, heat pump 16 work, the heat exchange tank 3 in the heat transfer medium to the heat transfer pipe 17 set in the outside of the concentration barrel 2, the material in the concentration barrel 2 is heated, temperature monitor 18 real-time monitoring temperature and data transmission to PLC controller 19, PLC controller 19 according to the set temperature control heat pump 16, ensure the concentration in the appropriate temperature.

[0040] Thirdly, the liquid produced by the concentration can be discharged through the liquid outlet pipe 7 collection, and the concentration barrel 2 bottom of the drain 8 for the discharge of waste residue, the whole process in the closed type concentration barrel 2 complete, circuit pipe 5 guarantee control box 4 and concentration barrel 2 between the power and signal transmission, support block 21 stable structure of each component, backflow pipe 20 ensure the heat transfer medium recycling, realize efficient, stable traditional Chinese medicine extraction concentration operation.

[0041] Finally, it should be pointed out that: the above described only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application has been made with reference to the foregoing embodiments, for the skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
