Description

Technical Field

[0001] The invention belongs to the technical field of traditional Chinese medicine component extraction, and particularly relates to a traditional Chinese medicine component extraction device and an extraction process. Background Art

[0002] The chemical composition of traditional Chinese medicine is very complex. It contains multiple effective ingredients, ineffective ingredients, and toxic ingredients. Extracting the effective ingredients and further separating and purifying them to obtain effective monomers is an important content in the field of traditional Chinese medicine research. Traditional Chinese medicine extraction is to use some technologies to extract the effective ingredients to the maximum extent, so that the intrinsic quality and clinical treatment effect of traditional Chinese medicine preparations are improved, and the effect of traditional Chinese medicine can be maximized. The extraction of traditional Chinese medicine is an important unit operation in the production process of traditional Chinese medicine. Its process methods, selection of process flow and equipment configuration will be directly related to the quality and clinical effect of traditional Chinese medicine. Traditional Chinese medicine extracts are new traditional Chinese medicine products that integrate modern pharmaceutical new technologies. At the same time, according to the existing public document CN110314752B, it can be seen that the extraction of traditional Chinese medicine components is a raw material product for the production of Chinese patent medicines made by extracting and purifying clean medicinal materials or processed products through leaching, clarification, filtration, evaporation and other methods.

[0003] Therefore, when extracting Chinese herbal medicine components, the water and medicinal materials are heated. Therefore, in order to ensure the dissolution state of the effective ingredients in the medicinal materials in the liquid, it is necessary to continuously add an appropriate amount of water to the equipment to ensure that the liquid medicine is fully concentrated. However, the existing equipment does not have the function of automatically adding water according to the height of the water level. Therefore, when extracting Chinese herbal medicine components, the staff needs to pay attention to the water level in the equipment at all times. At the same time, when using the equipment to extract Chinese herbal medicine components, it is not convenient to quickly cool and separate the heated steam in the equipment, so it is impossible to effectively separate the concentrated liquid medicine and steam, which will reduce the efficiency of Chinese herbal medicine component extraction. To this end, we provide a Chinese herbal medicine component extraction equipment and extraction process to solve the above problems. Summary of the invention

[0015] The present invention also provides a process for extracting components of traditional Chinese medicine, which is implemented by the following steps: S1: Select high-quality honeysuckle, scutellaria and forsythia, wash, air-dry or bake them to ensure the purity of the medicinal materials and the integrity of the active ingredients; S2: Put the processed medicinal materials into the kettle, add a certain amount of clean water, and pour 7 or 10 times the amount of water into the kettle for soaking. The soaking time is generally 1-3 hours, so that the active ingredients in the medicinal materials are fully dissolved; S3: When the soaking time of medicinal materials is over, water is added to the inside of the kettle, and the heater is controlled to heat the water and medicinal materials inside the kettle.

The addition of these auxiliary materials must follow a certain proportion to ensure the quality and safety of the product.

[0016] The present invention has the following beneficial effects: When the liquid inside the kettle body is gradually evaporated, the liquid level inside it will lower. When the height of the liquid level is lower than the lowest position of the stroke port, the stroke block slides downward, thereby driving the linkage rack to move downward, and controlling the rotation of the rotating tooth plate and the ball to rotate, so that the quantitative water adding pipe is opened, thereby adding water to the inside of the kettle body. When the liquid level inside the kettle body gradually rises, it will drive the stroke block to slide upward, thereby driving the linkage rack to move upward, and thereby driving the rotating tooth plate and the ball to reverse, so that the quantitative water adding pipe is closed, thereby realizing automatic water adding according to the height of the water level.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0032] See also Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a Chinese medicine component extraction device, which drives the linkage rack 402 to move according to the height of the water level, thereby controlling the opening and closing of the quantitative water adding pipe 401, thereby realizing automatic water adding.

[0033] Specifically, the extraction component 100 includes a kettle body 101, a movable cover 104 for sealing the lower port position of the kettle body 101, and a sealing cover 105 for sealing the upper port position of the kettle body 101; the condensation component 200 includes a condensation water tank 201 located at the periphery of the kettle body 101, a spiral condensation water pipe 202 connected to the inside of the condensation water tank 201, and a positioning frame 203 located at the spiral position of the condensation water pipe 202; a storage component 300 for storing liquid medicine is provided at a position between the condensation water pipe 202 and the kettle body 101, and the storage component 300 is composed of a storage box and an inlet and outlet pipeline; a linkage water adding component 400 includes a quantitative water adding pipe 401 and a linkage rack 402 located at the periphery of the kettle body 101; By setting up and using the above structure, the components of the Chinese medicinal materials are heated, mixed and extracted through the kettle body 101, and the generated steam is cooled by the condensation water pipe 202, wherein the storage box stores the concentrated medicinal liquid and the cooled steam liquid.

[0034] according to Figure 3 , Figure 4 , Figure 5 and Fig. 9A notch 101a is provided on the inner side wall of the kettle body 101, a square bar 101b is fixed to the inner side wall of the kettle body 101 at the position of the notch 101a, a through hole 101b-1 penetrating the lower end surface of the square bar 101b is provided on the upper end surface of the kettle body 101, a steam pipe port 101c is provided at the upper part of the side wall of the kettle body 101, a filter cloth 104a is fixed inside the movable cover 104, and the medicinal materials and water inside the kettle body 101 can be processed separately through the filter cloth 104a, a ball tube 401a is fixedly connected to the middle position of the quantitative water adding pipe 401, and a middle rotating valve 101a is provided inside the ball tube 401a. A sphere 403a having a hole diameter consistent with the inner diameter of the ball tube 401a is penetrated, and a rotating toothed plate 403 meshing with the linkage rack 402 is arranged on the periphery of the ball tube 401a, and a shaft is fixed between the rotating toothed plate 403 and the sphere 403a, and the shaft is used in conjunction with the ball tube 401a through a sealed bearing, the bottom end of the quantitative water adding pipe 401 is connected to the interior of the kettle body 101, and a hollow bar 402a sliding in the internal position of the through port 101b-1 is fixed on the upper end surface of the linkage rack 402, and a travel block 402b sliding in the internal position of the travel port 101b-2 is fixed on the lower end surface of the hollow bar 402a; When the above-mentioned structure is used, the medicinal materials and the solution are poured into the kettle 101, and after a period of soaking, water is added, and the interior of the kettle 101 is heated, and the steam generated will flow from the position of the steam pipe port 101c to the steam return pipe 102, and at the same time, the condensed water inside the condensed water tank 201 circulates from the position of the condensed water pipe 202, so that when the steam inside the steam return pipe 102 is cooled, the steam in the steam return pipe 102 is condensed from the liquid and flows back to the storage tank, and when the concentrated liquid medicine is recovered and stored, the valve on the bellows 104b can be opened, and the concentrated liquid medicine will flow into the storage tank through the bellows 104b; As the liquid inside the kettle body 101 gradually evaporates, the liquid level inside it will lower. When the height of the liquid level is lower than the lowest position of the stroke port 101b-2, the stroke block 402b slides downward, thereby driving the linkage rack 402 to move downward, and controlling the rotation of the toothed plate 403 and the ball 403a to rotate, so that the quantitative water adding pipe 401 is opened, thereby adding water to the inside of the kettle body 101. When the liquid level inside the kettle body 101 gradually rises, it will drive the stroke block 402b to slide upward, thereby driving the linkage rack 402 to move upward, and thereby driving the rotation of the toothed plate 403 and the ball 403a to reverse, so that the quantitative water adding pipe 401 is closed, thereby realizing automatic water adding according to the height of the water level.

[0035] Further, according to Figure 2 , Figure 3 and Figure 6It can be seen that a steam return pipe 102 is bolted at the position of the steam pipe mouth 101c, and the lower end surface of the steam return pipe 102 is connected to the inlet pipe of the storage box, and the bottom of the movable cover 104 is fixedly connected to the corrugated pipe 104b connected to the inlet pipe of the storage box; the condensate pipe 202 is spirally wound on the side wall of the positioning frame 203, and the positioning frame 203 is bolted on the side wall of the steam return pipe 102, and the interior of the storage box is divided into two spaces. The liquid condensed by the steam is stored in a separate space, and the discharged liquid medicine from the kettle body 101 will be stored in another separate space. At the same time, the condensate pipe 202 is connected to the water pump inside the condensate tank 201, and the condensate inside the condensate tank 201 is extracted by the water pump, so that the condensate flows from the lower port of the condensate pipe 202 to its upper port position, thereby improving the condensation effect of the steam in the steam return pipe 102.

[0036] Further, according to Figure 6 It can be seen that the bottom position of the condensation water tank 201 is fixedly connected with a discharge pipe 201b, and the upper end surface of the condensation water tank 201 is fixedly connected with an inlet pipe 201a. When condensate needs to be added to the inside of the condensation water tank 201, the inlet pipe 201a is opened to add the coolant inside the condensation water tank 201, and the valve on the discharge pipe 201b is opened at the same time to discharge the coolant inside the condensation water tank 201.

[0037] Further, according to Figure 8 It can be seen that a motor 105a is fixed at the middle position of the upper end surface of the sealing cover 105, and a stirring rod 105b fixedly connected to the rotating shaft end of the motor 105a is arranged directly below the sealing cover 105. A feeding pipe 105c connected to the interior of the kettle body 101 is fixed to the upper end surface of the sealing cover 105. By controlling the operation of the motor 105a, the motor 105a will drive the stirring rod 105b to rotate inside the kettle body 101, thereby ensuring that the medicinal materials and water inside the kettle body 101 can be fully mixed and preventing the medicinal materials inside the kettle body 101 from sticking to the pot.

[0038] It should be noted that the water pump, motor 105a and multiple cylinders used are all controlled by an external control center to make them work together. At the same time, the electrical structure used is powered by an external power supply. The quantitative water adding pipe 401 used is connected to the external water source, and the quantitative water adding pipe 401 is controlled to add water quantitatively. At the same time, valves are installed on the pipes used to control the opening and closing of the pipes through the staff. Example 2

[0039] See also Figure 2 , Figure 3 and Figure 7On the basis of Example 1, this embodiment ensures that the movable cover 104 can be accurately opened through the rotation connection between the L-shaped rotating plate 104c and the connecting plate 101d, so as to facilitate the discharge of the medicine residue.

[0040] Specifically, a connecting plate 101d is fixed to the side wall of the kettle body 101 just below the steam pipe port 101c, a lifting cylinder 101d-1 is fixed to the upper end of the connecting plate 101d, a shaft block 101d-2 is fixed to the piston end of the lower end of the lifting cylinder 101d-1, and a U-shaped plate 104e rotatably connected to the shaft block 101d-2 is fixed to the upper end surface of the protruding portion of the movable cover 104. When the movable cover 104 is driven to rotate, the movable cover 104 will drive the U-shaped plate 104e to rotate on the shaft block 101d-2, and the movable cover 104 An L-shaped rotating plate 104c is arranged around, a telescopic rod 104c-1 is fixed between the L-shaped rotating plate 104c and the movable cover 104, the upper end of the L-shaped rotating plate 104c is rotatably connected to the end of the connecting plate 101d, a heater 103 for heating the inside of the kettle body 101 is arranged between the angle cylinder 106 and the quantitative water adding pipe 401, and the heater 103 is fixed on the side wall of the kettle body 101, and the operation of the heater 103 is controlled, so that the heater 103 will heat the medicinal materials and solution inside the kettle body 101.

[0041] Through the arrangement and use of the above-mentioned structure, when the medicine residue inside the kettle body 101 needs to be discharged, the angle cylinder 106 and the lifting cylinder 101d-1 can be controlled to work synchronously, and then the lifting cylinder 101d-1 will push the movable cover 104 to move downward. Due to the rotational connection between the L-shaped rotating plate 104c and the connecting plate 101d, the movable cover 104 will rotate with the connecting plate 101d as the base point through the L-shaped rotating plate 104c, and then the telescopic rod 104c-1 between the movable cover 104 and the L-shaped rotating plate 104c will be pulled and retracted, and at the same time, the angle cylinder 106 will also be driven to rotate, so that the movable cover 104 can be opened, and the medicine residue inside the kettle body 101 can be directly discharged at this time. Example 3

[0042] See also Figure 3 , Figure 7 and Fig.10 On the basis of Example 1, this embodiment ensures that the angle cylinder 106 can rotate normally by using the support rod 101e and the ring 106a, the ball block 106b and the block 104d in coordination with each other.

[0043] Specifically, angle cylinders 106 are provided at the front and rear parts of the exterior of the kettle body 101, blocks 104d are fixed at the positions of the angle cylinders 106 on the circumferential sides of the movable cover 104, a ball hole 104d-1 is provided in the middle position of the upper end surface of the block 104d, a ball block 106b is fixed to the piston end of the angle cylinder 106 and is rotatably clamped in the inner position of the ball hole 104d-1, two support rods 101e are fixed to the circumferential side walls of the kettle body 101 and are located directly above the angle cylinder 106, a ring 106a is fixed to the upper end surface of the angle cylinder 106 and is sleeved on the support rod 101e, and a round block 101e-1 is fixed to the end of the support rod 101e for limiting the sliding position of the ring 106a.

[0044] Through the setting and use of the above-mentioned structure, when the angle cylinder 106 and the lifting cylinder 101d-1 are used in conjunction, the lifting cylinder 101d-1 will drive the ring 106a at the end of the angle cylinder 106 to rotate on the support rod 101e. At the same time, when the angle cylinder 106 is working, the ball block 106b on the angle cylinder 106 will rotate and move in the internal position of the ball mouth 104d-1.

[0045] The present invention also provides a process for extracting components of traditional Chinese medicine, which is implemented by the following steps: S1: Select high-quality honeysuckle, scutellaria and forsythia, wash, air-dry or bake them to ensure the purity of the medicinal materials and the integrity of the active ingredients; S2: Put the processed medicinal materials into the kettle 101, add a certain amount of clean water, and pour 7 or 10 times the amount of water into the kettle 101 for soaking. The soaking time is generally 1-3 hours, so that the active ingredients in the medicinal materials are fully dissolved; S3: After the soaking time of the medicinal materials is over, water is added to the inside of the kettle 101, and the heater 103 is controlled to work to heat the water and medicinal materials inside the kettle 101, and after boiling, it is switched to a low fire for slow stewing, and the slow stewing time needs to last for 3-5 hours until the medicinal liquid is concentrated; S4: During the slow cooking process, the motor 105a needs to be controlled to work, so that the motor 105a controls the stirring rod 105b to continuously stir the liquid and medicinal materials in the kettle 101 to prevent the medicinal materials in the kettle 101 from sticking to the pot; S5: When the liquid inside the kettle 101 is gradually evaporated, the liquid level inside it will decrease. When the height of the liquid level is lower than the lowest position of the stroke port 101b-2, the stroke block 402b slides downward, thereby driving the linkage rack 402 to move downward, and controlling the rotation of the rotating tooth plate 403 and the ball 403a to rotate, so that the quantitative water adding pipe 401 is opened, thereby adding water to the inside of the kettle 101. When the liquid level inside the kettle 101 gradually rises, it will drive the stroke block 402b to slide upward, thereby driving the linkage rack 402 to move upward, and thereby driving the rotation of the rotating tooth plate 403 and the ball 403a to reverse, so that the quantitative water adding pipe 401 is closed; S5: By intermittently adding an appropriate amount of water, the effective ingredients of the medicinal materials are kept dissolved in the liquid; S6: After decoction, the residue is removed, leaving the liquid medicine. In order to improve the extraction efficiency, a method of multiple decoctions and merging is usually adopted, that is, the medicinal materials are decocted multiple times, and then the liquid medicines from each decoction are mixed for use; S7: evaporating and concentrating the obtained medicinal solution until it reaches an appropriate concentration, and then drying the concentrated medicinal solution, usually by spray drying or freeze drying, to retain the active ingredients in the medicinal material; S8: In some cases, in order to improve the taste, increase stability or promote absorption, some auxiliary materials may be added, such as honey, glycerin, and stevia. The addition of these auxiliary materials must follow a certain proportion to ensure the quality and safety of the product.
