Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of traditional Chinese medicine processing, in particular to a traditional Chinese medicine concentrating device and a traditional Chinese medicine concentrating process. BACKGROUND

[0002] In the field of traditional Chinese medicine concentration, traditional Chinese medicine refers to a medicine made from Chinese herbal medicine as raw material based on traditional Chinese medicine theory through processing, extraction and concentration processes. Traditional Chinese medicine concentration is a process of removing water from traditional Chinese medicine juice or extract to improve the concentration and purity of the medicine. Traditional Chinese medicine concentration device is a device used for traditional Chinese medicine concentration. It controls temperature, pressure and flow rate, etc. by using heat transfer and evaporation principles to evaporate water in traditional Chinese medicine juice, so as to achieve the purpose of concentration. Traditional Chinese medicine concentration device is widely used in traditional Chinese medicine manufacturing and traditional Chinese medicine industry, which can improve the concentration and quality of the medicine and reduce the volume and storage cost.

[0003] Traditional traditional Chinese medicine concentration devices usually use evaporation technology, including multi-effect evaporator, vacuum evaporator and forced circulation evaporator, etc. These devices are mainly composed of heater, evaporator, condenser and pump components. The traditional Chinese medicine juice enters the evaporator under the action of the heater, and the water gradually evaporates through the heat transfer surface in the evaporator to form concentrated liquid. Then, the water vapor is cooled by the condenser to convert into liquid water, and the concentrated liquid is discharged from the device.

[0004] Firstly, the traditional evaporation concentration method usually needs a long time to reach the ideal concentration rate, and in the production process, a large amount of traditional Chinese medicine raw materials need to be processed. When the concentrated medicine tank is heated, it needs to provide heating for a long time to make the whole tank body at evaporation temperature. However, due to the large space of the tank, the heat consumption increases, and the heating time also increases, which leads to high energy consumption and low production efficiency. Secondly, the heat distribution of traditional evaporation device is uneven. Large volume of concentrated medicine tank needs to provide continuous and stable heat to ensure that the whole tank body can be at evaporation temperature. However, the heat propagation becomes slow due to the increase of the tank body, which leads to heat loss and energy waste in the concentration process.

[0005] In view of the above, we propose a traditional Chinese medicine concentrating device and a traditional Chinese medicine concentrating process. SUMMARY

[0006] The technical problem to be solved by the present application is that traditional Chinese medicine concentration needs to be heated for a long time in production, and the concentration efficiency of traditional Chinese medicine raw materials in the tank is low. Moreover, due to the large volume of the medicine tank, the heat inside is not uniform with the increase of temperature, which leads to inconsistent concentration rate of part of the traditional Chinese medicine raw materials, resulting in large overall concentration error.

[0007] The present application provides the following technical solutions:

[0008] This invention provides a traditional Chinese medicine concentration device, comprising a tank, a discharge valve, a motor, a steam inlet pipe, a concentration mechanism, an adjustment mechanism, a stirring mechanism, and a support. The device is characterized in that: the discharge valve is fixedly installed at the upper end of the tank; the motor is fixedly installed at the upper position of the tank, specifically by welding or bolting; the steam inlet pipe is fixedly installed at the lower end of the tank, specifically by welding or gluing, and is used to introduce steam; the concentration mechanism is fixedly installed in the lower half of the tank body, specifically by welding or screwing, and is used to increase the evaporation area of ​​the medicinal liquid, with openings on it for the passage of evaporating steam; the adjustment mechanism is fixedly installed on the upper surface of the concentration mechanism, specifically by welding or screwing, and steam enters the adjustment mechanism, creating pressure within it, thereby changing the state of the adjustment mechanism and opening its internal pathways, allowing the traditional Chinese medicine raw materials to begin concentration; the stirring mechanism is rotatably installed in the upper half of the tank body, and while rotating to sieve the traditional Chinese medicine raw materials, it also tumbles and stirs them; the support is fixedly installed at the bottom of the tank body, specifically by welding or screwing, and is used to support the tank body.

[0009] The concentration mechanism includes an outer shell, a steam outlet pipe, a lower evaporation plate, an upper evaporation plate, a guide pipe, and a vapor-liquid separation mechanism. The outer shell is fixedly connected to the inner wall of the tank and has a double-layer structure. Steam is introduced into the shell, and the gap between the two layers is 10mm-20mm. The steam outlet pipe is fixedly installed on the upper end face of the outer shell, specifically by welding or gluing. The steam outlet pipe is used to discharge the evaporated steam. The outer edge of the lower evaporation plate is fixedly installed on the outer shell, specifically by welding or snap-fitting. The lower evaporation plate is a boss-shaped structure extending downwards on all four sides. The guide pipe is fixedly connected to the center of the lower evaporation plate, specifically by welding. The function of the guide tube is to guide the flow of steam and medicinal liquid, ensuring their separation during evaporation. The center of the upper evaporation plate is fixedly connected to the upper end of the guide tube, either by welding or by snap-fit. The upper evaporation plate is a boss-shaped structure extending downward from the center. The distance between the upper and lower evaporation plates is 100mm-300mm, and there are 1-3 upper and lower evaporation plates. The vapor-liquid separation mechanism is fixedly connected to the upper end of the guide tube, either by welding or by bolting. The vapor-liquid separation mechanism is used to separate the liquid inlet channel of the Chinese herbal raw materials from the vapor of the liquid evaporation.

[0010] The double-layered structure of the outer shell allows steam to circulate and heat the interior of the tank. When the gap between the two layers is less than 10mm, the volume of the gap decreases, leading to increased internal pressure after steam enters. This increases the impact and compression on the inner wall, increasing the risk of shell breakage. Simultaneously, the reduced volume of the double-layered gap means less steam enters, resulting in insufficient heating temperature to meet the requirements for concentrating traditional Chinese medicine. When the gap between the two layers is greater than 20mm, the volume of the internal cavity increases, and correspondingly, the amount of steam it can hold also increases. This leads to a higher heating temperature in the tank. For some traditional Chinese medicine raw materials with lower concentration requirements, this is clearly unreasonable, as the increased temperature will also affect the medicinal properties of the raw materials.

[0011] Furthermore, the upper and lower evaporation plates are the main components of this invention for improving evaporation efficiency. When the distance between the upper and lower evaporation plates is less than 100mm, the small distance limits the evaporation area of ​​the medicinal liquid. The reduction in evaporation area will lead to a decrease in evaporation rate, thereby affecting the efficiency of Chinese medicine concentration. When the distance between the upper and lower evaporation plates is greater than 300mm, the excessive distance will cause uneven heat distribution inside the concentration mechanism. Some areas may overheat, while other areas cannot fully utilize the heat of the steam, resulting in uneven concentration effect.

[0012] Finally, the number of upper and lower evaporation plates should be 1-3, with a minimum of 1. When the number of upper and lower evaporation plates is greater than 3, the excessive number of upper and lower evaporation plates will increase the size and space occupied by the device, which may restrict the layout and installation of the equipment, and increase the complexity and cost of the equipment.

[0013] As described above, the guide pipe includes a pipe body, baffles, and flow channel holes. The baffles are fixedly installed on the inner wall of the pipe body, and there are 3-7 baffles. Their installation positions are staggered, and their inclination angle with the axis of the pipe body is upward and the angle is 30°-60°. The baffles are used to prevent the backflow of steam inside the guide pipe. Since some steam condenses into water droplets and accumulates on the inner wall of the guide pipe, the installation of baffles can prevent the condensed water droplets from flowing back into the tank. The flow channel holes are opened on the pipe body and are located at the bottom end of the baffles. The flow channel holes are used to discharge the steam condensation inside the pipe body.

[0014] Therefore, when the number of baffles is less than 3, the baffles cannot effectively prevent the backflow of steam in the guide pipe. The backflowing droplets will overflow from the guide pipe through the gaps and enter the tank, causing contamination of the Chinese herbal raw materials or reducing the concentration efficiency, affecting the uniform wetting and evaporation process of the Chinese herbal raw materials. When the number of baffles is more than 7, too many baffles will lead to space restriction and increased resistance to fluid flow, which will result in poor steam flow and pressure loss. Increasing the number of baffles will also increase the difficulty of maintaining the device.

[0015] Furthermore, selecting an installation angle for the baffles between 30° and 60° provides a good blocking effect and an appropriate steam flow rate, ensuring unidirectional steam flow within the guide tube. When the angle is less than 30°, some steam will flow back, affecting the normal operation of the concentration unit. It will also affect the efficiency of the evaporation process. Conversely, when the angle is greater than 60°, the steam flow rate will slow down, or even cause blockage, affecting the smooth progress of the evaporation process.

[0016] It is worth noting that the upper and lower evaporation plates are assembled by flipping up and down to achieve repeated evaporation and concentration of the medicinal liquid, thereby improving the concentration efficiency. The angle between the upper evaporation plate and the horizontal direction is 30°-45°, and the boss of the upper evaporation plate is stepped, with a step drop of 10mm-50mm. The lower evaporation plate is the same as the upper evaporation plate. The Chinese herbal raw materials will flow into the lower evaporation plate from the edge of the upper evaporation plate, while the lower evaporation plate will collect the medicinal liquid at its center and flow out.

[0017] Based on the above, the tilt angles of the upper and lower evaporation plates are used to improve the fluidity of the herbal liquid and increase evaporation efficiency. When the tilt angle is less than 30°, it will reduce the fluidity and uniformity of the liquid, affecting the evaporation efficiency and concentration effect. In addition, it will cause the liquid to accumulate on the surface of the upper evaporation plate, increasing the possibility of condensation. When the tilt angle is greater than 45°, the liquid will flow to the lower evaporation plate too quickly, making it impossible to form a stable thin layer for evaporation. This will lead to uneven evaporation of the liquid during the evaporation process.

[0018] When the height difference between the upper and lower evaporation plates is less than 10 mm, the liquid will flow quickly through the stepped areas of the upper and lower evaporation plates, resulting in a reduced residence time and affecting evaporation efficiency and concentration speed. In addition, it will make it difficult for the liquid to form a stable thin layer in the stepped area, affecting the uniformity and stability of evaporation. When the height difference is greater than 50 mm, the residence time of the liquid in the stepped area will be too long, causing some of the liquid to over-evaporate or condense in the stepped area. This will lead to uneven concentration and fluctuations in concentration speed, affecting the stability and performance of the device.

[0019] As described above, the vapor-liquid separation mechanism includes a liquid channel, a steam collecting plate, a steam exhaust pipe, a steam inlet, a steam distribution plate, and a steam distribution hole. The upper end of the liquid channel is fixedly connected to the regulating mechanism, specifically by welding or bolting. The steam collecting plate is fixedly installed at the lower end of the liquid channel, specifically by welding or screwing. The steam collecting plate is used to collect and discharge the steam in the guide pipe. The inner diameter of the steam collecting plate is 2-3 times the outer diameter of the liquid channel. The steam exhaust pipe is fixedly installed on the upper surface of the steam collecting plate, specifically by welding or... The steam distribution plate is glued together and the exhaust pipe is used to discharge steam. The steam inlet is opened on the lower end face of the steam collecting plate. The steam inlet is used to receive steam from the concentration mechanism. The steam distribution plate is fixedly installed on the inner wall of the liquid channel. The specific installation method is welding or screw connection. The steam distribution plate is used to divert the steam in the guide pipe into the steam collecting plate. The outer diameter of the steam distribution plate is 2 / 5-3 / 5 of the inner diameter of the liquid channel. The steam distribution holes are evenly opened on the side of the steam distribution plate. The number of steam distribution holes is 4-8. The steam distribution holes and the steam collecting plate are interconnected through the steam distribution holes.

[0020] The internal cavity of the steam collecting pan is used to collect steam from the concentration mechanism. The steam collecting pan is installed on the outer shell of the liquid channel. When the inner diameter of the steam collecting pan is less than twice the outer diameter of the liquid channel (i.e., the internal cavity is too small), the steam collection effect will be poor, and the steam will impact and pressure the steam collecting pan. When its inner diameter is greater than three times the outer diameter of the liquid channel (i.e., the internal cavity is too large), the steam collection capacity will increase, making it difficult to discharge in time, affecting heat exchange efficiency and increasing backflow. The steam distributor is installed inside the liquid channel, which will affect the liquid flow within the channel. Based on this design, the outer diameter of the steam distributor needs to be considered. When its outer diameter is less than 2 / 5 of the liquid channel, it will affect the internal steam channel, reducing the inner diameter of the steam distribution holes and increasing the internal steam pressure, thus reducing the service life of the device. When its outer diameter is greater than 3 / 5 of the liquid channel, it will reduce the space in the liquid channel, slowing down the flow rate of the liquid, resulting in insufficient liquid processing and affecting the concentration effect.

[0021] Therefore, steam distribution holes are evenly distributed on the side of the steam distribution plate, with a quantity of 4-8 holes. The function of the steam distribution holes is to divert steam and guide it into the steam collecting plate. The design and location of the steam distribution holes need to consider the uniformity and effectiveness of steam diversion. When the number of steam distribution holes is less than 4, steam discharge is obstructed, and a large amount of steam cannot be discharged in time, which will cause impact on the vicinity of the steam distribution holes. When the number of steam distribution holes is greater than 8, that is, too many steam distribution holes, the steam flow rate and pressure will decrease, and the area of ​​the steam distribution plate will increase, which will obstruct the liquid channel and affect the flow of the liquid medicine.

[0022] The regulating mechanism includes a sliding shell, a through hole, a steam pipe, a movable slider, a pressure regulating device, a liquid inlet channel, and a steam inlet pipe. The sliding shell is fixedly connected to the upper end of the liquid channel, specifically by welding or bolting. The wall thickness of the sliding shell is 4mm-10mm. The through hole is located at the center of the sliding shell, with an inner diameter of 10mm-20mm. The steam pipe is fixedly installed at one end of the sliding shell, specifically by welding or snap-fitting. The steam pipe is used to introduce steam. The movable slider is slidably installed inside the sliding shell. The movable slider has a through hole, and by sliding left and right, it opens and closes the liquid pipeline. The pressure regulating mechanism is slidably installed at the other end of the sliding shell. The pressure regulating mechanism utilizes the spring force and steam pressure balance to trigger steam at different temperatures and pressures. The liquid inlet channel is fixedly installed at the upper end of the sliding shell and aligned with the through hole, specifically by welding or bolting. The inner diameter of the liquid inlet channel is 2-4 times that of the through hole. The steam inlet pipe is fixedly installed at the upper end of the sliding shell, specifically by welding or snap-fitting.

[0023] Based on the above, the wall thickness of the sliding shell should range from 4mm to 10mm. This range provides sufficient strength and rigidity to ensure the structural stability and durability of the sliding shell during operation. A wall thickness greater than 10mm increases the volume of the sliding shell, leading to material waste and installation difficulty. Conversely, a wall thickness less than 4mm results in a thinner structure that is more fragile and increases processing difficulty. The through-hole is the flow channel for the traditional Chinese medicine liquid. Its inner diameter determines the flow rate and volume of the liquid. An inner diameter less than 10mm restricts the liquid flow, limiting its passage capacity and causing increased channel pressure, poor flow, or even blockage. An inner diameter greater than 20mm leads to excessive medium flow, exceeding the device's design range, resulting in increased pressure loss, system instability, or overload.

[0024] Furthermore, after the Chinese herbal medicine liquid is screened and stirred by the stirring mechanism, it flows into the liquid inlet channel. At this time, the liquid inlet channel needs to ensure that the inflow of liquid is limited to ensure that the amount of liquid concentrated each time is reasonable. When the inner diameter of the liquid inlet channel is less than twice the size of the through hole, the fluid flow will be limited, restricting the flow rate and flow of the liquid entering. This will affect the working efficiency and flow balance of the system, resulting in insufficient or unstable liquid supply. When its inner diameter is more than four times the size of the through hole, the liquid will enter the system in excess, exceeding the required flow rate. This will lead to pressure fluctuations, liquid overflow, or ineffective control of the liquid flow.

[0025] The pressure regulating device includes an adjusting screw, a limiting block, and an adjusting spring. The adjusting screw is rotatably mounted on the other end of the sliding shell. The thread length of the adjusting screw is 60mm-140mm, and the specification of the adjusting screw is M10-M18. The adjusting screw is used to change the tightness of the adjusting spring, thereby adjusting the trigger pressure of the steam. The limiting block is slidably mounted inside the sliding shell. The limiting slider is used to press the adjusting spring. The adjusting spring is slidably mounted on the limiting block, and the working stroke of the adjusting spring is 50mm-120mm.

[0026] Based on this design, the selection of the adjusting screw needs to consider its actual rotatable thread length. The thread length determines its adjustable range. When the thread length is less than 60mm, the adjustable range of the adjusting screw is too small, and it cannot effectively adjust the adjusting spring. When the thread length is greater than 140mm, the length of the adjusting spring is too long. This results in a large difference between the actual length and the effective length of the adjusting spring, wasting processing materials and increasing the difficulty of installation.

[0027] Furthermore, when the adjusting screw is smaller than M10, its strength cannot withstand high-intensity working conditions, and its service life will be greatly reduced; when the adjusting screw is larger than M18, it will cause a mismatch with the size of the device, increasing the difficulty of installation and use.

[0028] Furthermore, the adjusting spring balances the pressure brought by the steam through its extension and contraction. Its working stroke determines whether the through hole can slide to the connected position. When the working stroke of the adjusting spring is less than 50mm, it will result in too short a working stroke, and the steam will not be able to push the movable slider to the connected position. When its working stroke is greater than 120mm, it will result in too large a working stroke, and the movable slider will need to slide more to balance with the adjusting spring. This will also increase the length of the adjusting screw, making the processing and installation unreasonable.

[0029] The stirring mechanism includes a housing, a rotating shaft, a screen, a rotating plate, a base, and a discharge port. The housing is fixed, one end of the rotating shaft is fixedly connected to a motor, and the screen is fixedly installed at the other end of the rotating shaft. The screen is used to sieve the Chinese herbal raw materials and filter out the residues. The rotating plate is fixedly installed on the screen. There are 2-3 rotating plates, and the height of the rotating plates is 80mm-150mm. The rotating plates rotate together with the screen, thereby turning the Chinese herbal raw materials, thus accelerating the dissolution of the raw materials and the separation of the residues. The base is fixedly installed below the screen, and the inclination angle of the base to the horizontal direction is 20°-40°. The discharge port is located at the center of the base and is used for collection and convergence, so that the filtered Chinese herbal liquid flows out from the discharge port.

[0030] Based on the above, the mixing mechanism utilizes a combination of physical mixing and sieves to further accelerate the mixing and filtration efficiency. The number of rotating plates determines the degree of mixing. When there are fewer than two rotating plates, i.e., only one rotating plate, the mixing effect cannot meet the actual production needs. Moreover, because a single rotating plate experiences only one force during rotation, it may be damaged or deformed. When there are more than three rotating plates, the dense rotating plates will clog part of the sieve, leading to a reduction in filtration efficiency. Furthermore, too many rotating plates will cause over-mixing of the medicinal materials, producing a large amount of residue and affecting the quality of the medicinal materials. Simultaneously, the height of the rotating plates also affects the mixing and filtration effect. When the height of the rotating plates is less than 80mm, the mixing effect is not ideal. When the height of the rotating plates is greater than 150mm, the resistance experienced by the plates increases due to their excessive height, making them prone to deformation or even damage during rotation.

[0031] Furthermore, the tilt angle on the chassis causes the medicinal liquid to collect at the outlet. When the tilt angle is less than 20°, the rate of liquid collection slows down, which can cause the liquid to get stuck in the chassis and affect the discharge effect. When the tilt angle is greater than 40°, the processing height of the chassis will be increased to accommodate the excessively deep internal space of the chassis. Moreover, the rate of liquid collection is too fast, which will increase the pressure on the outlet.

[0032] A traditional Chinese medicine concentration process, comprising the following steps: (The process utilizes a traditional Chinese medicine concentration apparatus as described in any one of claims 1 to 8)

[0033] S1: Add 5kg of Chinese herbal medicine mixture into the tank through the discharge valve, turn on the motor, start the stirring mechanism, the rotating plate is vertically connected to the screen, and drive the screen to rotate together to stir and filter the Chinese herbal medicine mixture, so that the residue of the Chinese herbal medicine mixture is filtered out to obtain the original Chinese herbal medicine liquid.

[0034] S2: After the Chinese herbal medicine liquid is filtered, 100°C steam is introduced into the concentration mechanism through the steam inlet pipe. The concentration mechanism is heated to 100°C, and the regulating mechanism is subjected to the pressure of steam. Then, the movable slider in the regulating mechanism is pushed by the steam, thereby connecting the regulating mechanism and allowing the Chinese herbal medicine liquid to enter the concentration mechanism.

[0035] S3: The raw Chinese medicine liquid entering the concentration mechanism flows through the upper and lower evaporation plates to form a thin film of raw Chinese medicine liquid. Under continuous steam heating, it begins to evaporate, forming secondary steam and concentrated liquid.

[0036] S4: The secondary steam obtained through S3 enters the vapor-liquid separation mechanism through the guide pipe in the concentration mechanism. The condensate droplets of the secondary steam inside the guide pipe will enter the concentration mechanism again through the baffle on the guide pipe for secondary concentration.

[0037] S5: After the second concentration, the steam undergoes heat exchange, and the steam pressure drops to the point where the movable slider of the regulating mechanism closes the through hole. Then, wait for the concentration mechanism to heat up to 100°C again.

[0038] S6: Repeat steps S3-S5 until the concentration of the concentrate reaches the standard, and then the concentrate is discharged and collected through the bottom of the tank.

[0039] The beneficial effects of this invention are as follows:

[0040] 1. This invention incorporates a concentration mechanism inside the tank. Through the multi-layered design of the concentration mechanism, the herbal liquid flows through the upper evaporation plate and then into the lower evaporation plate, uniformly distributing the liquid and forming a thin film on the concentration mechanism. This accelerates the concentration efficiency. Furthermore, the stepped design of the upper and lower evaporation plates significantly increases the surface area for liquid flow, resulting in more thorough and uniform heating and improving the concentration rate.

[0041] 2. This invention installs an adjustment mechanism on the liquid channel, and tightens or loosens the adjustment spring by rotating the adjustment screw, thereby increasing or decreasing the trigger pressure of the steam. This allows for dynamic injection and concentration of the traditional Chinese medicine liquid based on the steam pressure and temperature, thus improving the concentration effect of the traditional Chinese medicine liquid.

[0042] 3. This invention improves the filtration efficiency and stirring effect of Chinese herbal raw materials by setting up a stirring mechanism, installing a vertical rotating plate and a freely rotating circular screen, and vertically mounting the rotating plate on the upper surface of the screen along the center of the screen. This allows the rotating plate to stir the medicinal liquid while driving the screen to rotate and sieve the medicinal liquid, thus improving the filtration efficiency and stirring effect of the Chinese herbal raw materials.

[0043] 4. The present invention provides baffles and flow channel holes on the inner wall of the guide tube. When secondary steam enters the guide tube and forms condensation reflux, the generated droplets are collected by the baffles. The baffles are staggered inside the guide tube to ensure that they do not obstruct the passage of secondary steam. At the same time, they can collect the reflux droplets, so that the droplets flow into the concentration mechanism from the flow channel holes at the bottom of the baffles, thereby achieving secondary concentration.

[0057] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figure 1 and Figure 2As shown, this invention provides a traditional Chinese medicine concentration device, including a tank 1, a discharge valve 2, a motor 3, a steam inlet pipe 4, a concentration mechanism 5, an adjustment mechanism 6, a stirring mechanism 7, and a support 8. The tank 1 is the main container of the entire device, used to hold the raw materials and steam. The discharge valve 2 is fixedly installed at the upper end of the tank 1 to control the discharge of the medicinal liquid. The motor 3 is fixedly installed above the tank 1 using bolts. The steam inlet pipe 4 is fixedly installed at the lower end of the tank 1 using welding, and is used to introduce steam to provide heat for the concentration process. The concentration mechanism 5 is fixedly installed inside the lower half of the tank 1 using welding. Equipped with a double-layer structure and openings for steam passage, the concentration mechanism 5 receives the medicinal liquid through its internal double-layer structure to increase the evaporation area of ​​the liquid. The openings on it allow steam to pass through, thereby improving its heat exchange efficiency. The regulating mechanism 6 is fixedly installed on the upper end face of the concentration mechanism 5, specifically by screw connection. Steam enters the regulating mechanism 6, creating pressure within it, thereby changing the state of the regulating mechanism 6 and opening its internal passages, allowing the medicinal raw materials to begin to concentrate. The stirring mechanism 7 is rotatably installed on the upper half of the tank 1. While rotating to sieve the medicinal raw materials, the stirring mechanism 7 also flips and stirs them. The support 8 is fixedly installed at the bottom end of the tank 1, specifically by welding, and is used to support the tank 1.

[0059] During operation, the raw materials of traditional Chinese medicine are poured into the tank 1 through the discharge valve 2. At this time, the motor 3 starts running, driving the stirring mechanism 7 to rotate, thereby stirring and filtering the raw materials of traditional Chinese medicine. Steam is introduced through the air inlet pipe, waiting for the tank 1 to heat up. At the same time, the steam enters the regulating mechanism 6. When the steam reaches the trigger pressure, the regulating mechanism 6 opens, and the liquid medicine enters the concentration mechanism 5. The concentration mechanism 5 concentrates and evaporates the liquid medicine. When the steam temperature is absorbed, the steam pressure drops, thereby closing the regulating mechanism 6. This allows the steam to fully concentrate the liquid medicine in the concentration mechanism 5. The process is repeated when the steam reaches the trigger pressure again, thereby achieving efficient concentration of traditional Chinese medicine.

[0060] like Figure 3 and Figure 4As shown, the concentration mechanism 5 includes a shell 51, a steam outlet pipe 52, a lower evaporation plate 53, an upper evaporation plate 54, a guide pipe 55, and a vapor-liquid separation mechanism 56. The shell 51 is fixedly connected to the inner wall of the tank. The shell 51 has a double-layer structure, and steam is introduced into its interior. The gap between the two layers of the shell 51 is the channel through which the steam passes. The movement of steam within the gap heats the tank 1. Therefore, the volume of the gap determines the amount of steam that can be contained, which in turn determines the heating temperature of the tank 1. For the concentration process of traditional Chinese medicine, the heating and evaporation temperature should not be too high, otherwise the medicinal properties of the traditional Chinese medicine will be affected or even destroyed. Therefore, the double-layer gap of the outer shell 51 is selected to be 12mm. This gap distance ensures a suitable amount of steam entering and a stable steam temperature, providing a continuous and stable heating effect. Furthermore, the heating temperature of the tank 1 is also reasonable. The steam outlet pipe 52 is fixedly installed on the upper surface of the outer shell 51 by welding. The steam outlet pipe 52 is used to discharge evaporated steam. The outer edge of the evaporation lower plate 53 is fixedly installed on the outer shell 51 by snap-fit. The evaporation lower plate 53 is a boss-shaped structure extending downwards on all four sides. The downward extension of the evaporation plate guides the liquid medicine downwards, and the bosses on it increase the liquid medicine's... The flow surface area of ​​the liquid is considered. The guide pipe 55 is fixedly connected to the center of the lower evaporation plate 53 by snap-fit. The function of the guide pipe 55 is to guide the flow of steam and liquid, ensuring their separation during evaporation. The center of the upper evaporation plate 54 is fixedly connected to the upper end of the guide pipe 55 by snap-fit. Since the upper evaporation plate 54 and the lower evaporation plate 53 are used together, a combination of multiple layers of the upper evaporation plate 54 and the lower evaporation plate 53 is selected according to different concentration requirements. Considering the need for frequent disassembly and installation, the installation method of both the upper evaporation plate 54 and the lower evaporation plate 53 adopts snap-fit. The upper evaporation plate 54 is a convex shape extending downward from the center. The Chinese medicine liquid flows from the upper evaporation plate 54 into the lower evaporation plate 53, thereby achieving the effect of multiple concentrations and improving the concentration efficiency. At this time, it is necessary to consider the distance between the upper evaporation plate 54 and the lower evaporation plate 53. The distance between the upper evaporation plate 54 and the lower evaporation plate 53 is 150mm. There is only one upper evaporation plate 54 and one lower evaporation plate 53. The vapor-liquid diversion mechanism 56 is fixedly connected to the upper end of the guide pipe 55. The specific installation method is welding. The vapor-liquid diversion mechanism 56 is used to separate the liquid inlet channel 66 of the Chinese medicine raw material from the vapor of the liquid.

[0061] The double-layer structure of the outer shell 51 allows steam to circulate and heat the inside of the tank 1. The gap between the two layers of the outer shell 51 determines the amount of steam entering the tank, which affects the heating temperature of the tank 1. Furthermore, the upper evaporation plate 54 and the lower evaporation plate 53 are the main components of this invention for improving evaporation efficiency. These two are installed in a rotating and mating manner. Both the upper evaporation plate 54 and the lower evaporation plate 53 are designed with bosses. This design helps to increase the evaporation area, allowing the liquid medicine to be more fully exposed to the steam, thereby promoting the evaporation process.

[0062] When the concentration mechanism 5 is working, steam and Chinese herbal medicine liquid enter the liquid pipe from the discharge port 76, and then enter the vapor-liquid diversion mechanism 56. After that, it flows to the first-stage protrusion of the upper evaporation plate 54. As the liquid continues to flow in, it flows down the first-stage protrusion layer by layer until it flows into the lower evaporation plate 53 from the edge gap of the upper evaporation plate 54. The lower evaporation plate 53 causes the liquid to gather towards the center. Finally, the liquid flows out from the central opening. During this process, the liquid flows through layers and forms a thin film of liquid on the surface of the upper evaporation plate 54 and the lower evaporation plate 53. This will accelerate the concentration efficiency of the liquid. Moreover, the steam generated after the liquid evaporates will flow with the guide pipe 55 and then be discharged through the steam outlet pipe 52.

[0063] like Figure 4As shown, the guide pipe 55 includes a pipe body 551, baffles 552, and flow channel holes 553. The pipe body 551 is fixedly installed at the center of the upper evaporation plate 54, and the baffles 552 are fixedly installed on the inner wall of the pipe body 551. The baffles 552 are used to prevent backflowing steam droplets from re-entering the liquid. Since this embodiment uses a single-stage concentration evaporation, i.e., one upper evaporation plate 54 and one lower evaporation plate 53, five baffles 552 are selected. Their installation positions are staggered, and their angle with the axis of the pipe body 551 is upward at 45°. The baffles 552 are used to prevent the backflow of steam inside the guide pipe 55. Since some steam condenses into water droplets and accumulates on the inner wall of the guide pipe 55, the installation of the baffles 552 prevents condensation. Water droplets will not flow back into the tank 1. The flow channel hole 553 is opened on the tube 551 and located at the bottom end of the baffle 552. The flow channel hole 553 is used to discharge the condensation of steam in the tube 551. When the medicine in the concentration mechanism 5 absorbs the heat of the external steam and evaporates to generate secondary steam, the steam will be discharged through the guide pipe 55. As heat is lost, the secondary steam will partially condense and flow back, and droplets will adhere to the inner wall of the guide pipe 55. In order to prevent droplets from re-entering the medicine, five staggered baffles 552 are set on the inner wall of the tube 551. This design can effectively control the flow of steam, prevent the backflow phenomenon, and ensure that the condensate of steam in the guide pipe 55 is discharged, maintaining the normal operation of the device.

[0064] Too few baffles 552 cannot effectively prevent the backflow of steam in the guide pipe. During the backflow, the steam carries droplets, which will overflow from the guide pipe 55 through the gaps and enter the tank, causing contamination of the Chinese herbal raw materials or reducing the concentration efficiency, affecting the uniform wetting and evaporation process of the Chinese herbal raw materials. Too many baffles 552 will increase the blockage and congestion in the guide pipe, resulting in space restriction and increased resistance to fluid flow. This will lead to poor steam flow and pressure loss, affecting the performance and efficiency of the concentration device. Increasing the number of baffles 552 will also increase the maintenance difficulty of the device.

[0065] Furthermore, selecting an installation angle for the baffle 552 between 30° and 60° provides a good blocking effect and an appropriate steam flow rate, ensuring unidirectional steam flow within the guide pipe 55 and preventing backflow. If the angle is too small, the deflection of steam passing through the baffle 552 will decrease, resulting in an unsatisfactory blocking effect. This can lead to partial steam backflow, affecting the normal operation of the concentration unit. Additionally, a small angle may reduce the steam flow rate within the guide pipe 55, affecting the efficiency of the evaporation process; conversely, a large angle increases the deflection of steam passing through the baffle 552, but may also cause excessive resistance. This could slow down the steam flow rate or even cause blockage, affecting the smooth operation of the evaporation process.

[0066] like Figure 5 As shown, the upper evaporation plate 54 and the lower evaporation plate 53 are assembled by flipping up and down. The medicinal liquid will first flow through the upper evaporation plate 54, which is recessed from the edges, and then enter the lower evaporation plate 53, which is recessed downward from the center. This achieves repeated evaporation and concentration of the medicinal liquid, which can greatly increase the flow surface area of ​​the medicinal liquid and improve the concentration efficiency. The upper evaporation plate 54 is tilted at an angle of 45° to the horizontal direction. The protrusion of the upper evaporation plate 54 is stepped, and the step drop is 15mm. The lower evaporation plate 53 is the same as the upper evaporation plate 54. The Chinese herbal raw materials will flow into the lower evaporation plate 53 from the edge of the upper evaporation plate 54, and the lower evaporation plate 53 will collect the medicinal liquid at its center and flow out.

[0067] The inclination angles of the upper evaporation plate 54 and the lower evaporation plate 53 are used to improve the fluidity of the traditional Chinese medicine liquid and increase the evaporation efficiency. However, when the inclination angle is too small, the flow rate of the liquid through the concentration mechanism 5 will decrease, which will reduce the fluidity and uniformity of the liquid, resulting in an excessively long evaporation time, affecting the evaporation efficiency and concentration effect. In addition, it will also cause the liquid to accumulate on the surface of the upper evaporation plate, increasing the possibility of condensation. When the inclination angle is too large, the flow rate of the liquid will increase, causing the liquid to flow to the lower evaporation plate 53 too quickly. This will prevent the liquid from forming a stable thin layer for evaporation within the concentration mechanism, leading to uneven evaporation of the liquid during the evaporation process.

[0068] like Figure 6As shown, the vapor-liquid diversion mechanism 56 includes a liquid channel 561, a steam collecting plate 562, a steam exhaust pipe 563, a steam inlet 564, a steam distribution plate 565, and a steam distribution hole 566. The upper end of the liquid channel 561 is fixedly connected to the regulating mechanism 6 by welding. The steam collecting plate 562 is fixedly installed at the lower end of the liquid channel 561 by welding. The steam collecting plate 562 is used to collect and discharge the steam in the guide pipe 55. The inner diameter of the steam collecting plate 562 is twice the outer diameter of the liquid channel 561. The steam exhaust pipe 563 is fixedly installed on the upper end face of the steam collecting plate 562 by welding. The steam exhaust pipe 563 is used for... Steam is discharged. The steam inlet 564 is opened on the lower end face of the steam collecting plate 562. The steam inlet 564 is used to receive steam from the concentration mechanism 5. The steam distribution plate 565 is fixedly installed on the inner wall of the liquid channel 561. The specific installation method is screw connection. The steam distribution plate 565 is used to divert the steam in the guide pipe 55 into the steam collecting plate 562. The outer diameter of the steam distribution plate 565 is 2 / 5 of the inner diameter of the liquid channel 561. The steam distribution holes 566 are evenly opened on the side of the steam distribution plate 565. There are 5 steam distribution holes 566. The steam distribution holes 566 and the steam collecting plate 562 are interconnected through the steam distribution holes 566.

[0069] During operation, the herbal medicine liquid enters the vapor-liquid splitting mechanism 56 through the liquid channel 561, and then flows into the concentration mechanism 5. After concentration by the concentration mechanism 5, secondary steam is generated. The secondary steam enters the vapor-liquid splitting mechanism 56 through the guide pipe 55. The herbal medicine liquid and the secondary steam enter the outer surface and the interior of the vapor-liquid splitting mechanism 56, respectively, thereby achieving the splitting of liquid and steam. The secondary steam then enters the steam collecting plate 562 through the steam distribution hole 566 on the steam distribution plate 565. The secondary steam also enters through the steam inlet hole 564 at the lower end of the steam collecting plate 562. Therefore, the secondary steam will collect in the steam collecting plate 562 and finally be discharged through the exhaust pipe 563.

[0070] like Figure 7 and Figure 8As shown, the regulating mechanism 6 includes a sliding shell 61, a through hole 62, a steam pipe 63, a movable slider 64, a pressure regulating device 65, a liquid inlet channel 66, and a steam inlet pipe 67. The sliding shell 61 is fixedly connected to the upper end of the liquid channel 561 by welding. The wall thickness of the sliding shell 61 is 5mm, which improves the strength of the support and can withstand the pressure of the internal steam. The through hole 62 is located at the center of the sliding shell 61, and the inner diameter of the through hole 62 is 16mm to ensure a reasonable and uniform flow rate of the liquid. The steam pipe 63 is fixedly installed at one end of the sliding shell 61 by snap-fit. The steam pipe 63 is used to introduce steam. The movable slider 64 is slidably installed on the sliding shell 61. Inside the sliding shell 61, the movable slider 64 has a through hole 62. The movable slider 64 slides left and right to open and close the liquid pipeline. The pressure regulating mechanism is slidably installed at the other end of the sliding shell 61. The pressure regulating mechanism uses the spring force and steam pressure to balance, thereby triggering steam at different temperatures and pressures. The liquid inlet channel 66 is fixedly installed at the upper end of the sliding shell 61 and aligned with the through hole 62. The specific installation method is welding. The inner diameter of the liquid inlet channel 66 is twice that of the through hole 62. The steam pipe 67 is fixedly installed at the upper end of the sliding shell 61. The specific installation method is snap-fit. The steam pipe 67 is used for steam discharge.

[0071] When the regulating mechanism 6 is working: Steam enters the regulating mechanism 6 through the steam pipe 63, creating pressure inside. The movable slider 64 slides within the sliding shell 61 under the pressure of the steam, causing the through hole 62 to be open. At this time, the Chinese medicine liquid enters the regulating mechanism 6 through the liquid inlet channel 66 and flows out through the through hole 62, thus completing the opening action of the regulating mechanism 6. When the steam pressure decreases, the movable slider 64 slides under the pressure of the pressure regulating device 65, thereby causing the through hole 62 to be disconnected, thus completing the closing action of the regulating mechanism 6.

[0072] like Figure 8As shown, the pressure regulating device 65 includes an adjusting screw 651, a limiting block 652, and an adjusting spring 653. The adjusting screw 651 is rotatably mounted on the other end of the sliding shell 61. The thread length of the adjusting screw 651 is 80mm, and the specification of the adjusting screw 651 is M12. The adjusting spring 653 is used to adjust the tightness of the adjusting spring 653, thereby adjusting the trigger pressure of the steam. The limiting block 652 is slidably mounted inside the sliding shell 61. The limiting block 652 is used to press the adjusting spring 653 to maintain the stability and working state of the regulating device. The sliding design of the limiting block 652 allows the adjusting spring 653 to move freely within a specified working stroke, ensuring the reliability and stability of the system. The adjusting spring 653 is slidably mounted on the limiting block 652, and the working stroke of the adjusting spring 653 is 80mm. This design and installation method of the pressure regulating device 65 can adjust the trigger pressure of the steam according to the needs, realizing precise control of the traditional Chinese medicine concentration device.

[0073] like Figure 9 and Figure 10 As shown, the stirring mechanism 7 includes a housing 71, a rotating shaft 72, a screen 73, a rotating plate 74, a base 75, and a discharge port 76. The housing 71 is fixed. One end of the rotating shaft 72 is fixedly connected to the motor 3. The screen 73 is fixedly installed at the other end of the rotating shaft 72. The screen 73 is used to sieve the Chinese herbal medicine raw materials and filter out the residues in the raw materials. The rotating plate 74 is fixedly installed on the screen 73 by welding. There are three rotating plates 74, and the height of each rotating plate 74 is 80mm. The rotating plates 74 rotate together with the screen 73, thereby turning over the Chinese herbal medicine raw materials, thus accelerating the dissolution of the raw materials and the separation of the residues. The base 75 is fixedly installed below the screen 73. The angle between the base 75 and the horizontal direction is 20°. The discharge port 76 is located at the center of the base 75. The base 75 is used for collection and confluence, so that the filtered Chinese herbal medicine liquid flows out from the discharge port 76.

[0074] During operation, the stirring mechanism 7 rotates under the drive of the motor 3. The motor 3 drives the rotating shaft 72 to rotate, thereby driving the screen 73 to rotate. Since the rotating plate 74 is welded to the screen 73, the rotating plate 74 also rotates at the same time. The rotating plate 74 causes the Chinese herbal raw materials to tumble and stir, making them dissolve more fully. The Chinese herbal raw materials pass through the screen 73 and the residue is filtered out. The filtered Chinese herbal liquid is collected at the discharge port 76 through the inclined plate on the base 75 and finally flows out of the stirring mechanism 7.

[0075] like Figure 11As shown, a traditional Chinese medicine concentration process is described, which uses a traditional Chinese medicine concentration device as described in any one of claims 1 to 8. The traditional Chinese medicine concentration process includes the following steps:

[0076] S1: Add 5kg of Chinese herbal medicine mixture into tank 1 through discharge valve 2, turn on motor 3, start stirring mechanism 7, rotate plate 74 vertically connected to screen 73, drive screen 73 to rotate together, stir and filter Chinese herbal medicine mixture, so that the Chinese herbal medicine mixture is filtered to remove residue and obtain Chinese herbal medicine raw liquid.

[0077] S2: After the Chinese herbal medicine raw liquid is filtered, 100°C steam is introduced into the concentration mechanism 5 through the steam inlet pipe 4. After the concentration mechanism 5 is heated to 100°C, the regulating mechanism 6 is subjected to the pressure of steam. Then the movable slider 64 inside the regulating mechanism 6 is pushed by the steam, so that the regulating mechanism 6 is connected and the Chinese herbal medicine raw liquid enters the concentration mechanism 5.

[0078] S3: The Chinese herbal medicine liquid entering the concentration unit 5 flows through the upper evaporation plate 54 and the lower evaporation plate 53 to form a thin film of Chinese herbal medicine liquid. Under continuous steam heating, it begins to evaporate, forming secondary steam and concentrated liquid.

[0079] S4: The secondary steam obtained through S3 enters the vapor-liquid splitting mechanism 56 from the guide pipe 55 in the concentration mechanism 5. The condensate droplets of the secondary steam inside the guide pipe 55 will enter the concentration mechanism 5 again through the baffle on the guide pipe 55 for secondary concentration.

[0080] S5: After the second concentration, the steam undergoes heat exchange, and the steam pressure drops to the point where the movable slider 64 of the regulating mechanism 6 closes the through hole 62. Then, wait for the concentration mechanism 5 to heat up to 100°C.

[0081] S6: Repeat steps S3-S5 until the concentration of the concentrate reaches the standard, and then the concentrate is discharged and collected through the bottom of tank 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
