Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine concentration technology, specifically to a traditional Chinese medicine concentration tank that utilizes active flow generation to reduce component loss. Background Technology

[0002] The essence of Chinese medicine concentration lies in using distillation technology combined with pressurization or depressurization to purify the Chinese medicine juice. The common Chinese medicine concentration process is carried out in a concentration tank. It should be noted that the medicinal properties of Chinese medicine vary, and the decoction time of various medicinal materials is different. The common saying "simmer over low heat" is not entirely suitable for the Chinese medicine concentration process.

[0003] Following on from the above, the conventional concentration process involves heating a batch of Chinese herbal medicines "simultaneously," resulting in an excessively long overall heating time. While the purpose of Chinese herbal medicine concentration is to remove water from the juice, prolonged heating leads to a loss of medicinal properties (some effective components), disrupting the balance of efficacy. In particular, the Chinese herbal medicines closest to the inner wall of the container have the "longest" contact time with the heat source, which can cause the bottom to burn (damage to the inside of the container). This application proposes a solution to this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a Chinese medicine concentration tank that utilizes active flow generation to reduce component loss. This is specifically for the concentration process of Chinese medicine juice, where the overall heating time of the Chinese medicine juice is relatively long, resulting in partial destruction of its medicinal properties. In some cases, the Chinese medicine juice in certain locations may even be "burnt" and completely destroy its medicinal properties, thus losing the effective components of the Chinese medicine juice.

[0005] The objective of this invention can be achieved through the following technical solution: a Chinese medicine concentration tank that utilizes active flow generation to reduce component loss, comprising one or more tanks, wherein an exhaust port and a secondary heating port are respectively installed at the upper and lower ends of the tank, an upper flow plate and a lower flow plate are respectively arranged inside the tank along the direction from top to bottom, and a laminar flow plate is arranged linearly and equidistantly along the vertical direction at the middle position corresponding to the upper flow plate and the lower flow plate inside the tank; The tank body is equipped with an injection sleeve and a collection sleeve at the upper end of the upper flow plate and at the lower flow plate, respectively. The upper flow plate, laminar flow plate and lower flow plate are inclined downward in the horizontal direction and are arranged in an alternating symmetrical manner along the width direction of the tank body. A primary heating port is installed on the outer side of the tank corresponding to the laminar flow plate, and an installation sleeve corresponding to the laminar flow plate is installed on the outside of the tank. A telescopic cylinder is installed on the lower side of the tank corresponding to the installation sleeve.

[0006] The upper surface of the upper flow plate is further configured such that a groove corresponding to the width direction of the upper flow plate is formed on the upper surface of the upper flow plate, and a flow-blocking impeller corresponding to the width direction of the upper flow plate is rotatably installed inside the groove. The lengths of the upper flow plate, laminar flow plate, and lower flow plate are less than the inner diameter of the tank.

[0007] Further configuration: multiple arc-shaped flow channels are provided on the upper surface of the laminar flow plate; the upper flow plate and the laminar flow plate are rotatably connected to the inner wall of the tank; and the lower flow plate is fixedly connected to the tank.

[0008] The configuration is further defined as follows: the primary heating port includes multiple jet ports, each jet port has an upwardly inclined jet direction along the horizontal direction, and the jet port is positioned higher than the laminar flow plate.

[0009] The configuration is further defined as follows: the widths of the upper flow plate, laminar flow plate, and lower flow plate decrease at equal arithmetic progressions from top to bottom, and the width of the lower flow plate decreases in the direction pointing towards the flow collector sleeve.

[0010] The following configuration is further provided: the flow collecting sleeve is inclined downward in the horizontal direction, and one end of the flow collecting sleeve extends to the outside of the tank body, while the other end of the flow collecting sleeve is provided with a full wrapping part, which is located at the bottom end of the lower flow plate.

[0011] The laminar flow plate is further configured such that: directional columns are installed on the upper surface of the laminar flow plate, the direction of the directional columns is perpendicular to the upper surface of the laminar flow plate, and the directional columns are linearly and equidistantly arranged along the length and width directions of the laminar flow plate; A metal ball sleeve is installed at the bottom of the upper surface of the directional column corresponding to the laminar flow plate, and a movable column is slidably installed at the upper end of the directional column. A connecting spring is provided at the middle section of the movable column corresponding to the inside of the directional column.

[0012] The configuration is further defined as follows: metal impactors are installed at both the upper and lower ends of the movable column, and a central impactor and multiple side impactors are provided inside the metal ball sleeve. The diameters of the side impactors are different and smaller than the diameter of the central impactor.

[0013] Further configuration: the rotation shafts of the upper flow plate and the laminar flow plate corresponding to the tank body extend to the outside of the tank body, and directional gears are installed on the rotation shafts of the upper flow plate and the laminar flow plate. The directional gears are located inside the mounting sleeve. A vertically upward straight gear plate is installed at the output end of the telescopic cylinder. The straight gear plate meshes with the directional gear, and the straight gear plate is slidably connected in the vertical direction inside the mounting sleeve.

[0014] The present invention has the following beneficial effects: 1. Compared with conventional methods of concentrating Chinese herbal medicine, this overall method uses hot air as a heat source and has a significant difference: the overall structure actively creates flow of the Chinese herbal medicine through the upper flow plate and laminar flow plate, thereby changing the relative state of the Chinese herbal medicine during the concentration process. Compared with Chinese herbal medicine in a static state, Chinese herbal medicine in a continuous flow mode is more conducive to water evaporation when in contact with the heat source. The purpose is to shorten the overall concentration cycle by using active flow generation while meeting the concentration requirements. 2. Further explanation based on the above: The upper flow plate and laminar flow plate can perform staggered angle deflection actions. On the basis of active flow generation, the flow velocity of the Chinese medicine juice is further changed by the flow-blocking impeller and the arc-shaped flow channel. As for the hot air blowing method, a two-stage hot air heating method is formed by the primary heating port and the secondary heating port. While maintaining the concentration temperature, the direction of the hot air jet in the primary heating port is used to further limit the speed of the Chinese medicine juice. The angle deflection action is used to generate local vibration through the directional column and the moving column, which further accelerates the evaporation rate of water in the Chinese medicine juice and avoids the loss of effective ingredients during continuous heating.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: The essence of the concentration process of traditional Chinese medicine juice is to continuously heat the juice to evaporate the water. However, conventional concentration processes involve "simultaneous heating" of batches of juice, which can be understood as the juice being in a relatively static state. This prolongs the overall heating process, resulting in some loss of the effective components of the juice and disrupting the balance of efficacy. In particular, the juice near the inner wall of the container has the "longest" contact time with the heat source, which can lead to burnt bottom and damage to the inside of the container. Therefore, the following technical solution is proposed: Reference Figures 1 to 7 This embodiment of a Chinese medicine concentration tank that utilizes active flow generation to reduce component loss includes one or more tank bodies 1. An exhaust port 3 and a secondary heating port 7 are respectively installed at the upper and lower ends of the tank body 1. An upper flow plate 8 and a lower flow plate 12 are respectively arranged inside the tank body 1 from top to bottom. A laminar flow plate 9 is arranged linearly and equidistantly in the vertical direction at the middle position corresponding to the upper flow plate 8 and the lower flow plate 12 inside the tank body 1. The tank body 1 is equipped with an injection sleeve 2 and a collection sleeve 11 at the upper end of the upper flow plate 8 and the lower flow plate 12, respectively. The upper flow plate 8, laminar flow plate 9 and lower flow plate 12 are inclined downward in the horizontal direction, and the upper flow plate 8, laminar flow plate 9 and lower flow plate 12 are arranged in an alternating symmetrical manner along the width direction of the tank body 1. A primary heating port 4 is installed on the outer side of the tank body 1 corresponding to the upper side of the laminar flow plate 9, and an installation sleeve 5 corresponding to the laminar flow plate 9 is installed on the outside of the tank body 1. A telescopic cylinder 6 is installed on the lower side of the tank body 1 corresponding to the installation sleeve 5. The widths of the upper flow plate 8, laminar flow plate 9 and lower flow plate 12 decrease at equal intervals from top to bottom. The width of the lower flow plate 12 decreases in the direction pointing towards the collecting sleeve 11. The collecting sleeve 11 is inclined downward in the horizontal direction, and one end of the collecting sleeve 11 extends to the outside of the tank body 1. A full wrap 1101 is provided at the other end of the collecting sleeve 11. The full wrap 1101 is located at the bottom of the lower flow plate 12. The primary heating port 4 contains multiple jet ports. The jet direction of each jet port is inclined upward in the horizontal direction, and the position of the jet port is higher than that of the laminar flow plate 9.

[0020] Working principle: The significant difference between this invention and the conventional Chinese medicine juice concentration process lies in the fact that the Chinese medicine juice to be processed is injected into the tank 1 through the injection sleeve 2, as described above. Figure 2 To explain, the herbal juice is obstructed by the upper flow plate 8, laminar flow plate 9, and lower flow plate 12, and flows downwards in sequence. Thus, the herbal juice is actively generated through the above three structures. It can be understood that the herbal juice is in a continuous flow state. Through the high temperature, high pressure or low pressure environment inside the tank 1, the water in the herbal juice is evaporated faster. Compared with the conventional concentration process, the herbal juice is not in a continuous heating state. Instead, after a part of the herbal juice comes into contact with the heat source and evaporates, it flows out from the lower flow plate 12-collecting sleeve 11. Therefore, this invention requires one or more tanks 1. Specifically, after the herbal juice has undergone the heating process in the first tank 1, if the concentration requirements are not met, the herbal juice flowing out of the first tank 1 is injected into the second tank 1 through the injection sleeve 2 for further concentration. It should also be noted that the heating method used in this invention differs from the conventional concentration method. Specifically, hot air is used as the heat source, and the temperature of the hot air is not limited in this invention. It is mainly used to introduce the method of hot air inlet. First, the hot air inlet 7 is inlet in a secondary heating port. Its purpose is to accelerate the flow of the evaporated water vapor from bottom to top and out of the exhaust port 3, based on providing a heat source. The primary heating port 4 also has the ability to provide a heat source, but its key purpose is to work with the laminar flow plate 9 to further restrict the flow of the Chinese herbal medicine juice.

[0021] Example 2: This example illustrates the laminar flow plate and upper flow plate structures from Example 1: A groove corresponding to the width direction of the upper flow plate 8 is provided on the upper surface of the upper flow plate 8, and a flow-blocking impeller 801 corresponding to the width direction of the upper flow plate 8 is rotatably installed inside the groove. The lengths of the upper flow plate 8, laminar flow plate 9 and lower flow plate 12 are less than the inner diameter of the tank body 1. Multiple arc-shaped flow grooves 901 are provided on the upper surface of the laminar flow plate 9. The upper flow plate 8 and laminar flow plate 9 are rotatably connected to the inner wall of the tank body 1, and the lower flow plate 12 is fixedly connected to the tank body 1. The upper flow plate 8 and the laminar flow plate 9 are connected to the rotation shaft of the tank body 1 and extend to the outside of the tank body 1. A directional gear 13 is installed on the rotation shaft of the upper flow plate 8 and the laminar flow plate 9. The directional gear 13 is located inside the mounting sleeve 5. A vertically upward straight gear plate 19 is installed at the output end of the telescopic cylinder 6. The straight gear plate 19 meshes with the directional gear 13. The straight gear plate 19 is slidably connected in the vertical direction inside the mounting sleeve 5.

[0022] As shown in Example 1, the herbal juice in the overall structure forms an active flow pattern that flows sequentially from top to bottom. However, under the influence of gravity, the speed of an object falling from a height will increase, thus requiring further restriction of the upper flow plate 8 and laminar flow plate 9 in the overall device, as shown below: S1: As the first structure to "bear" the Chinese medicine juice, the upper flow plate 8 needs to be equipped with multiple rotating flow-blocking impellers 801 to prevent the Chinese medicine juice from flowing too fast. These impellers are mainly used to "consume" the flow rate of the Chinese medicine juice. Similarly, the arc-shaped flow grooves 901 on each laminar flow plate 9 are also structures used to limit the flow rate of the Chinese medicine juice. S2: As shown in S1, relying solely on the flow-blocking impeller 801 and the arc-shaped flow channel 901 is insufficient to meet the requirements for adjusting the flow rate of the herbal juice. These two components primarily act as "obstructions" to the herbal juice. Because the upper flow plate 8 and laminar flow plate 9 are inclined, theoretically, the flow rate of the herbal juice is only directly related to its height. (Refer to...) Figure 7 The telescopic cylinder 6 drives the straight gear plate 19 to move in the vertical direction, which in turn drives the directional gear 13 to rotate at a small angle, thereby achieving the angle deflection of the laminar flow plate 9 and the upper flow plate 8. like Figure 2As shown, the initial velocity of the herbal juice flowing out of the upper flow plate 8 or laminar flow plate 9 is related to its height, and its height is related to the tilt angle of the upper flow plate 8 or laminar flow plate 9. The larger the tilt angle, the greater the height, and consequently the higher the initial velocity. In order to further limit the flow rate of the herbal juice, the laminar flow plates 9 on both sides of the tank 1 need to be rotated in coordination. For example, if the tilt angle of each laminar flow plate 9 and the upper flow plate 8 is ±3°, and the herbal juice flows out from the first laminar flow plate 9 on the upper right to the first laminar flow plate 9 on the upper left, in order to reduce the initial velocity of the herbal juice flowing out to the first laminar flow plate 9 on the upper left, the tilt angle of the first laminar flow plate 9 on the upper right needs to be increased to 4~5°. This is mainly to shorten the height between the end of the first laminar flow plate 9 on the upper right and the first laminar flow plate 9 on the upper left, thereby reducing the initial velocity of the herbal juice. However, the tilt angle of the first laminar flow plate 9 on the upper left needs to be reduced to 1~2°. In this way, the laminar flow plates 9 on both sides rotate periodically in a clockwise or counterclockwise direction. In this embodiment, the rotation period of the laminar flow plates 9 can be set to 3 seconds. Specifically, when the laminar flow plate 9 on the left side is rotating counterclockwise, the laminar flow plate 9 on the right side is rotating clockwise. If the rotation angle of the laminar flow plates 9 on both sides is set to 2°, then the rotation period is used to indicate that the 2° rotation action is completed within 3 seconds. After that, the laminar flow plate 9 on the left side rotates clockwise while the laminar flow plate 9 on the right side rotates counterclockwise. This process is repeated alternately to prolong the concentration time of the Chinese medicine juice inside the tank 1 and improve the water evaporation efficiency. S3: Refer again Figure 2 To explain, the primary heating port 4 is also a heat source inlet, but its function differs from that of the secondary heating port 7: when hot air is ejected from the primary heating port 4, it will directly blow on the surface of the Chinese medicine juice in the laminar flow plate 9. On the one hand, it uses the flow rate of the hot air to further "hinder" the flow rate of the Chinese medicine juice, and on the other hand, it "breaks" the balance of the Chinese medicine juice surface, accelerating the evaporation of water from the Chinese medicine juice.

[0023] Example 3: This example is a supplementary explanation to Example 2: A directional column 10 is installed on the upper surface of the laminar flow plate 9. The directional column 10 is set perpendicular to the upper surface of the laminar flow plate 9, and the directional column 10 is set linearly and equidistantly along the length and width of the laminar flow plate 9. A metal ball sleeve 16 is installed at the bottom of the upper surface of the directional column 10 corresponding to the laminar flow plate 9, and a movable column 14 is slidably installed at the upper end of the directional column 10. A connecting spring 15 is provided at the middle section of the movable column 14 corresponding to the inside of the directional column 10. Metal bumpers are installed at both the upper and lower ends of the movable column 14. A central bumper 18 and multiple side bumpers 17 are provided inside the metal ball sleeve 16. The diameters of the side bumpers 17 are different and smaller than the diameter of the central bumper 18.

[0024] Solution Description: As in S2 of Embodiment 2, since the laminar flow plates 9 on the left and right sides are in a staggered rotation state, taking two adjacent laminar flow plates 9 as an example, when the laminar flow plate 9 in the lower position deflects upward and the laminar flow plate 9 in the upper position deflects downward, the laminar flow plate 9 in the upper position will collide with the movable column 14 in the laminar flow plate 9 in the lower position. Specifically, the movable column 14 moves downward along the setting direction of the directional column 10, so that the metal bumper at the lower position of the movable column 14 hits the central bumper 18 inside the metal ball sleeve 16. The central bumper 18, the side bumper 17 and the metal ball sleeve 16 are all made of stainless steel or similar metal materials. The main purpose is to utilize the vibration generated when the metals collide, so that the lower side of the directional column 10 will produce "ripples" on the Chinese medicine juice contained in the laminar flow plate 9. Its essence is still to "break" the liquid surface balance of the Chinese medicine juice, and it can also limit and buffer the deflection process of the two adjacent laminar flow plates 9.

[0025] In summary, the significant difference between this invention and conventional methods of concentrating traditional Chinese medicine (TCM) juice lies in the active flow generation of the TCM juice to alter its relative state. Furthermore, a two-stage hot air heating method is employed. Essentially, the TCM juice flows continuously from top to bottom, and its flow velocity is further altered by changing the inclination of the upper and lower flow plates. The hot air inlet process includes both bottom-to-top and laminar flow plate approaches. While meeting the concentration temperature requirements, the hot air inlet further limits the flow rate of the TCM juice and accelerates water evaporation. Combined with the inclination of the upper and laminar flow plates, local vibration is generated using directional and movable columns. The overall goal is to shorten the concentration cycle and reduce the loss of active ingredients while meeting concentration requirements.
