Description

Technical Field

[0001] This invention relates to the field of active pharmaceutical ingredient (API) sterilization technology, and more specifically, to an output sterilization device for Ginkgo biloba extract API. Background Technology

[0002] Ginkgo biloba extract, as a natural extract, mainly contains two core components: flavonoid glycosides and ginkgolides. It has pharmacological properties such as anti-oxidation, anti-inflammation, improving blood circulation, and anti-platelet aggregation. However, it is easily oxidized and sensitive to temperature, and the stability of its active ingredients is easily affected by the processing.

[0003] In practical use, there are still shortcomings. Traditional drying methods rely on high-temperature heating, which can easily lead to oxidation and deterioration of the raw materials. Even if low-temperature drying is used, the lack of effective anti-oxidation protection measures causes the raw materials to oxidize when they come into contact with air during the drying process, reducing their efficacy. At the same time, uneven mixing of materials and incomplete removal of moisture during the drying process affect the subsequent sterilization effect. Sterilization mechanisms are mostly straight-channel structures, and the residence time of the raw materials in the sterilization area is fixed, which cannot be flexibly adjusted according to the characteristics of the batch of materials. This can easily lead to incomplete sterilization or over-sterilization, resulting in loss of efficacy.

[0004] Based on this, the present invention discloses a sterilization device for discharging Ginkgo biloba extract raw material. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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] Traditional drying methods often rely on high-temperature heating, which can easily lead to oxidation and deterioration of raw pharmaceutical materials. Even when using low-temperature drying, the lack of effective anti-oxidation protection measures causes the raw pharmaceutical materials to undergo oxidation reactions when in contact with air during the drying process, reducing their efficacy. At the same time, uneven mixing of materials and incomplete removal of moisture during the drying process affect the subsequent sterilization effect. Sterilization mechanisms are mostly straight-channel structures, and the residence time of raw pharmaceutical materials in the sterilization area is fixed, which cannot be flexibly adjusted according to the characteristics of material batches. This can easily lead to incomplete sterilization or over-sterilization, resulting in loss of efficacy.

[0020] Therefore, this invention provides a sterilization device for discharging Ginkgo biloba extract raw material, see [link to relevant documentation]. Figure 1-7 As shown, it includes a support frame 1, a servo motor A2 is fixedly connected to the top outer side of the support frame 1, a synchronous belt group 3 is provided at the output end of the servo motor A2, and a drying cylinder 4 is fixedly connected to the top inner side of the support frame 1. A low-temperature drying component is located inside the drying cylinder 4. The low-temperature drying component includes a connecting mechanism, a powder conveying mechanism, and an airflow depressurization mechanism. The powder conveying mechanism and the airflow depressurization mechanism are used in conjunction. The sterilization component is located inside the support frame 1 on one side, and the sterilization component includes a quantitative conveying mechanism and a finished product output mechanism.

[0021] The low-temperature drying assembly includes a stirring rod 5, a humidity sensor 6, a controller 7, an inert gas cylinder 8, an airflow pipe 9, an air pump 10, an air inlet pipe 11, and an exhaust pipe 17. The stirring rod 5 is installed inside the drying cylinder 4. The humidity sensor 6 is fixedly connected to the bottom inner side of the drying cylinder 4. The controller 7 is fixedly connected to the humidity sensor 6 near the humidity sensor 6 on the outer side of the drying cylinder 4. The controller 7 is electrically connected to the humidity sensor 6. The inert gas cylinder 8 is fixedly connected to the middle inner side of the support frame 1. The airflow pipe 9 is fixedly connected to the output end of the inert gas cylinder 8. The air pump 10 is fixedly connected to the top outer side of the support frame 1. The air pump 10 is connected to the airflow pipe 9. The air inlet pipe 11 is fixedly connected to the output end of the air pump 10 and is connected to the drying cylinder 4. The exhaust pipe 17 is fixedly connected to one side of the outer side of the drying cylinder 4. The stirring rod 5 can fully stir the raw materials in the drying cylinder 4, so that the materials are in uniform contact with the inert gas, improving the drying uniformity and efficiency, and making the materials dry more thoroughly. The humidity sensor 6 can collect the humidity data of the materials in real time and transmit it to the controller 7, realizing the automated monitoring and control of the drying process without manual operation, improving control accuracy. The inert gas cylinder 8 stores inert gas, which is pumped into the drying cylinder 4 through the air inlet pipe 11 in cooperation with the air pump 10 via the air flow pipe 9. This isolates the raw materials from air and slows down the oxidation of the raw materials, ensuring efficacy. The exhaust pipe 17 can promptly discharge the waste gas carrying moisture, maintaining stable air pressure in the drying cylinder 4, so that the drying process can continue to be carried out efficiently. The air flow pipe 9 realizes the stable delivery of inert gas, and the air pump 10 provides power for the air flow, and the air flow intensity can be adjusted to adapt to different drying needs.

[0022] The connecting mechanism includes a threaded cylinder 12, an electric telescopic rod 13, a limiting pin 14, and a mating thread 15. The outer end of the stirring rod 5 is provided with a mating thread 15, and the limiting pin 14 is slidably connected inside the mating thread 15. The threaded cylinder 12 is sleeved on the outer side of the limiting pin 14, and the threaded cylinder 12 is threadedly connected to the mating thread 15. One end of the synchronous belt group 3 servo motor A2 is fixedly connected to the electric telescopic rod 13, and the telescopic end of the electric telescopic rod 13 is fixedly connected to the limiting pin 14.

[0023] The powder transport mechanism includes a sealing plug 16 and a discharge pipe A18. The sealing plug 16 is connected to the side of the stirring rod 5 with the thread 15. The discharge pipe A18 is connected to the outside of the drying cylinder 4. The sealing plug 16 and the discharge pipe A18 are used together.

[0024] The airflow pressure relief mechanism includes a first pressure reducing valve 19 and a second pressure reducing valve 20. The first pressure reducing valve 19 is fixedly connected to the middle of the outer side of the discharge pipe A18, and the second pressure reducing valve 20 is fixedly connected to the middle of the outer side of the discharge pipe A18. The first pressure reducing valve 19 can initially relieve the pressure of the airflow in the rising section of the discharge pipe A18, reduce the material conveying resistance, and reduce the risk of blockage. The second pressure reducing valve 20 relieves pressure again in the bending and descending section of the discharge pipe A18, accurately controlling the airflow intensity entering the sterilization cylinder 111, reducing the interference of high-intensity airflow with the sterilization environment, and keeping the sterilization effect stable. The two-stage pressure relief design can flexibly adjust the airflow pressure to adapt to different material conveying and sterilization needs, and improve the equipment adaptability.

[0025] The sterilization assembly includes a sterilization cylinder 111, a feeding plate 21, a spiral sterilization tube 22, a through hole 222, and a sterilization module 223. The sterilization cylinder 111 is fixedly connected to one side of the support frame 1. The feeding plate 21 is fixedly connected to the top of the inner side of the sterilization cylinder 111. The sterilization cylinder 111 is connected to the discharge pipe A18. The spiral sterilization tube 22 is fixedly connected to the bottom of the outer side of the feeding plate 21. The through hole 222 is provided on the outer side of the spiral sterilization tube 22. The sterilization module 223 is fixedly connected to the inner side of the air inlet pipe 11. The sterilization module 223 is located inside the spiral sterilization tube 22.

[0026] The quantitative conveying mechanism includes a quantitative feeding module 23, a discharge pipe B24, a conveyor belt A25, a processing module 26, a servo motor B27, a discharge chamber 28, a servo motor C29, a bag rolling shaft 30, and a bag inlet 31. The discharge chamber 28 is fixedly connected to the bottom inner side of the support frame 1. The sterilization cylinder 111 communicates with the discharge chamber 28. The quantitative feeding module 23 is fixedly connected to the bottom inner side of the air inlet pipe 11. The discharge pipe B24 is fixedly connected to the bottom outer side of the quantitative feeding module 23. The conveyor belt A25 is located in the middle of the inner side of the discharge chamber 28. A processing module 26 is fixedly connected to the top of the inner side of the discharge cavity 28. The processing module 26 is located outside the conveyor belt A25. A servo motor B27 is fixedly connected to the outer side of the discharge cavity 28. The output end of the servo motor B27 is fixedly connected to the conveyor belt A25. A servo motor C29 is fixedly connected to the outer side of the discharge cavity 28 near the conveyor belt A25. A bag rolling shaft 30 is fixedly connected to the output end of the servo motor C29. The bag rolling shaft 30 rotates inside the discharge cavity 28. A bag inlet hole 31 is opened on the outer side of the processing module 26 near the bag rolling shaft 30.

[0027] The finished product output mechanism includes a conveying bag B32, and the conveying bag B32 is fixedly connected to the outside of the discharge chamber 28 on the side away from the servo motor B27.

[0028] During operation, the entire device is first fixedly installed using the support frame 1, ensuring stable operation of all internal components. Then, the ginkgo leaf extract is injected into the drying cylinder 4, and the servo motor A2 is started. The servo motor A2 transmits power through the synchronous belt group 3, driving the stirring rod 5 to rotate inside the drying cylinder 4. The stirring rod 5 and the synchronous belt group 3 are connected through a connecting mechanism.

[0029] The controller 7 starts the air pump 10, which draws inert gas from the inert gas cylinder 8 through the airflow pipe 9 and pumps it into the drying cylinder 4 through the air inlet pipe 11. The stirring rod 5 rotates continuously, ensuring that the inert gas comes into full contact with the raw material, forming a stable airflow. The airflow carries the moisture inside the raw material and discharges it through the exhaust pipe 17, achieving low-temperature drying. At the same time, the inert gas fills the drying cylinder 4, isolating it from air and slowing down the oxidation of the raw material. During the drying process, the humidity sensor 6 at the bottom of the inner side of the drying cylinder 4 monitors the material humidity in real time and transmits the data to the controller 7. When the humidity reaches the preset qualified value, the drying is complete. When it is necessary to replace or maintain the stirring rod 5, unscrew the threaded sleeve 12 to disengage the threaded sleeve 12 from the mating thread 15 on the stirring rod 5, and pull out the limit pin 14 to remove the stirring rod 5. The operation is convenient. The entire operation process is integrated and controlled by the controller 7, requiring minimal manual intervention and significantly improving processing efficiency and stability.

[0030] The controller 7 drives the electric telescopic rod 13 to extend and retract. The electric telescopic rod 13 moves the limit pin 14, which, together with the thread 15 and the threaded cylinder 12, moves the stirring rod 5 as a whole, causing the sealing plug 16 on the stirring rod 5 to disengage from the discharge pipe A18. At the same time, the controller 7 controls the exhaust pipe 17 to close and controls the air pump 10 to increase the airflow input, blowing the raw materials in the drying cylinder 4 into the discharge pipe A18. The rising section of the discharge pipe A18 has only one bend to reduce the risk of material blockage. At the same time, the first pressure reducing valve 19 performs initial pressure relief to reduce the conveying resistance. When the material reaches the top bend of the discharge pipe A18, it slides towards the sterilization cylinder 111 under the combined action of gravity and airflow thrust. The second pressure reducing valve 20 releases pressure again to reduce the airflow intensity and avoid interfering with the sterilization process. The material smoothly enters the spiral sterilization tube 22 inside the sterilization cylinder 111 through the feeding plate 21.

[0031] When the sterilization module 223 is activated, sterilization factors are released through the through hole 222. The spiral sterilization tube 22 extends the residence time of the raw material, allowing the material to fully contact the sterilization factors and achieve thorough sterilization. The operator can control the residence time of the material in the spiral sterilization tube 22 by adjusting the pressure relief rate of the first pressure reducing valve 19 and the second pressure reducing valve 20, so as to adapt to the sterilization requirements of different batches of materials.

[0032] After sterilization, the raw material enters the discharge chamber 28. The quantitative feeding module 23 precisely controls the feeding amount, and the material is evenly injected into the surface of the conveyor belt A25 through the discharge pipe B24. At this time, the conveyor belt A25 carries the material into the processing module 26. Simultaneously, the servo motor C29 starts, driving the bag roll shaft 30 to rotate, automatically conveying the packaging roll material through the bag inlet 31. The processing module 26 bags the raw material entering the processing module 26, and performs positioning, sealing and other processing on the packaging bags. The servo motor B27 drives the conveyor belt A25 to run, transporting the packaged finished product to the conveyor bag B32, realizing centralized output.

[0033] Inert gas from the inert gas cylinder 8 is pumped into the drying cylinder 4 by the air pump 10. Combined with the stirring action of the stirring rod 5, the airflow makes full contact with the raw material, which can quickly remove the moisture from the material to achieve low-temperature drying, and isolate the raw material from the air to prevent oxidation, effectively ensuring the efficacy of the raw material. At the same time, the humidity sensor 6 detects the humidity of the material in real time, and the controller 7 automatically controls the drying and discharge process to achieve intelligent control of the drying process, improving the drying accuracy and efficiency. The application of the spiral sterilization tube 22, together with the through hole 222 and the sterilization module 223, extends the residence time of the raw material in the sterilization area. At the same time, the pressure relief valve can be adjusted to flexibly control the material residence time, adapting to the sterilization requirements of different batches of raw materials, improving the controllability of the sterilization effect, and further increasing the practicality and reliability of the device.

[0034] For details, see Figure 1 , Figure 4-5 As shown, a hinge shaft 33 is hinged to the top of the outer side of the discharge chamber 28, and an opening and closing plate 34 is hinged to the outer side of the hinge shaft 33. A threaded dustproof sleeve 35 is fixed to one side of the outer side of the stirring rod 5, and the end of the threaded dustproof sleeve 35 away from the stirring rod 5 is fixed to the synchronous belt group 3.

[0035] The opening and closing plate 34 is opened by the hinge shaft 33 to clean and inspect the internal components of the discharge chamber 28. The opening and closing plate 34 is hinged to the discharge chamber 28 by the hinge shaft 33, which can be opened and closed flexibly. This makes it convenient for operators to maintain, inspect and clean the components such as the conveyor belt A25 and the roll bag shaft 30 inside the discharge chamber 28. At the same time, when closed, it ensures the sealing of the discharge chamber 28, reduces material contamination and noise leakage. Meanwhile, the threaded dustproof sleeve 35 protects the connection parts from dust, reduces the interference of dust on power transmission, reduces the entry of raw material dust into the connection gap, which may cause wear or jamming, extends the service life of parts, and ensures the stability and smoothness of power transmission.

[0036] In summary, this method effectively solves the problems of traditional drying methods that rely heavily on high-temperature heating, which can easily lead to oxidation and deterioration of raw materials. Even when using low-temperature drying, the lack of effective anti-oxidation protection measures causes the raw materials to oxidize upon contact with air during the drying process, reducing their efficacy. In addition, uneven mixing of materials and incomplete moisture removal during the drying process affect the subsequent sterilization effect. Sterilization mechanisms are mostly straight-channel structures, and the residence time of raw materials in the sterilization area is fixed, which cannot be flexibly adjusted according to the characteristics of material batches, easily leading to incomplete sterilization or over-sterilization and loss of efficacy.
