[0002] Traditional Chinese medicine (TCM) has a complex chemical composition, and some heat-sensitive active ingredients can be destroyed, volatilized, or degraded at high temperatures, directly affecting therapeutic efficacy and even causing serious adverse reactions. Some TCMs undergo changes in their medicinal properties under high temperatures, altering their original purpose. Some may even produce toxic substances, directly endangering patients' lives. Certain TCMs may produce toxic substances during sterilization, and these residues inevitably pose safety risks to patients. Whether irradiation sterilization of TCM leaves residues remains controversial in the industry, but this issue will be resolved with the development of detection technologies.

[0003] Therefore, sterilization is a crucial step in the manufacturing process of traditional Chinese medicine (TCM), directly affecting the quality of the medicines. The development of new sterilization technologies is a key focus for the technological transformation and upgrading of the TCM pharmaceutical industry, and is related to the modernization of TCM. With the trend towards standardization, high efficiency, and low carbon emissions in sterilization processes, it is essential to leverage the characteristics of various sterilization technologies, utilizing their respective strengths and, when necessary, coordinating them to move towards integration and modularization.

[0021] The core of this invention is to provide a sterilization system for traditional Chinese medicine powder, which can achieve automated steam sterilization and has excellent cooling and dehumidification effects, thus ensuring the quality of the traditional Chinese medicine powder.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a specific embodiment of the traditional Chinese medicine powder sterilization system provided by this utility model.

[0024] This utility model provides a traditional Chinese medicine powder sterilization system, comprising an automatic raw material supply device 1, a pressure suction device 2, a continuous material supply device 3, a dehumidification and cooling device, and a filling device connected in sequence. The continuous material supply device 3 is connected to a steam generator. Powder is placed inside the automatic raw material supply device 1. The pressure suction device 2 transports the powder in the automatic raw material supply device 1 to the continuous material supply device 3 through vacuum negative pressure. The steam generator transports high-temperature steam to the continuous material supply device 3 to mix and sterilize with the powder. After sterilization, the powder is dehumidified and cooled by the dehumidification and cooling device before being transported to the filling device for filling.

[0025] During operation, the material tank of the automatic raw material supply device contains traditional Chinese medicine powder. A pressure suction device transports the powder to a continuous material supply device, where a steam generator supplies high-temperature steam to sterilize the powder. The powder is then conveyed to a dehumidification and cooling device for multiple dehumidification and cooling processes before final filling. This system achieves automated steam sterilization with excellent cooling and dehumidification effects, ensuring the quality of the powder. The sterilization technology is upgraded towards standardization, high efficiency, and low carbon emissions, achieving equipment integration and modularization.

[0026] In the traditional Chinese medicine powder sterilization system provided in this specific embodiment of the invention, the automatic raw material supply device 1 is equipped with a powder inlet and an air inlet. The traditional Chinese medicine powder and air enter the automatic raw material supply device 1 respectively, and the air and powder are mixed inside the automatic raw material supply device 1. Specifically, the traditional Chinese medicine powder is transported to the automatic raw material supply device 1 by various methods such as conveyor belt or vacuum feeding, and the powder is mixed with filtered air at a ratio of 2:8.

[0027] The pressure suction device 2 is equipped with a vacuum feeding device at the top and a filter barrel inside. After the air-powder mixture inside the pressure suction device 2 is filtered by the filter barrel, the powder is conveyed downward to the material continuous supply device 3, and the air is discharged upward.

[0028] The continuous material supply device 3 has a feed inlet at the top, which is connected to the pressure suction device 2. The continuous material supply device 3 also has a discharge outlet at the bottom, which is connected to a dehumidification and cooling device. A steam port is located on the side of the continuous material supply device 3, which is connected to a steam generator. The herbal powder undergoes high-temperature steam sterilization within the continuous material supply device 3, with the sterilization time and temperature controlled.

[0029] Specifically, a first switching valve 31 and a second switching valve 32 are sequentially arranged between the lower outlet of the pressure suction device 2 and the inlet of the material continuous supply device 3. The first switching valve 31 and the second switching valve 32 are opened and closed alternately. A third switching valve 33 and a fourth switching valve 34 are sequentially arranged between the outlet of the material continuous supply device 3 and the inlet of the dehumidification and cooling device. The third switching valve 33 and the fourth switching valve 34 are opened and closed alternately.

[0030] The powder is inhaled at set time intervals. The powder can be visually observed through the pressure suction device 2, and the inhalation time and volume can be adjusted accordingly. After determining the inhalation time, the first switch valve 31 and the second switch valve 32 are switched. When the first switch valve 31 is open, the second switch valve 32 is closed, and when the first switch valve 31 is closed, the second switch valve 32 is open. The switching interval is adjusted by the time setting, which is generally within 5 to 15 seconds. The time difference is used to ensure the internal pressure of the material continuous supply device 3 and stabilize the pressure. At this time, the raw material is stably supplied to the material continuous supply device 3, and superheated steam for sterilization is supplied to the material continuous supply device 3. The residence time is set according to the sterilization temperature. The pressure is cut off between the material continuous supply device 3 and the dehumidification and cooling device by the third switch valve 33 and the fourth switch valve 34 to prevent backflow of raw materials. In order to cut off the steam and prevent hot air backflow, the opening and closing times of the third switch valve 33 and the fourth switch valve 34 are set. During raw material conveying, the fourth switch valve 34 is set to close and the third switch valve 33 is set to open. After the fourth switch valve 34 closes for a few seconds, the third switch valve 33 opens. Specifically, when the fourth switch valve 34 is closed and the third switch valve 33 is open, the raw material from the continuous material supply device 3 flows downwards and accumulates on top of the fourth switch valve 34 after passing through the third switch valve 33. After the third switch valve 33 closes for a few seconds, the fourth switch valve 34 opens, and the raw material between the third switch valve 33 and the fourth switch valve 34 is then conveyed to the dehumidification and cooling device.

[0031] It also includes a controller 10, which is communicatively connected to a first switching valve 31, a second switching valve 32, a third switching valve 33, and a fourth switching valve 34. A temperature detector connected to the controller 10 is installed within the continuous material supply device 3. The controller 10 can control the opening and closing times of each switching valve. Each valve is an electromagnetic switching valve, but other types of valves may also be used, all within the protection scope of this utility model.

[0032] The steam generating unit includes a primary steam generator 4 and a secondary steam generator 5 connected in sequence. The inlet of the primary steam generator 4 is connected to a pure water supply device, the outlet of the primary steam generator 4 is connected to the inlet of the secondary steam generator 5, and the outlet of the secondary steam generator 5 is connected to the steam port of the continuous material supply device 3. The pure water undergoes two treatments through the primary steam generator 4 and the secondary steam generator 5 before the steam is delivered to the continuous material supply device 3.

[0033] The steam generating device also includes a hot air generator 6, a first gas filter 7, a steam heating valve group 8, and a gas heater 9. The inlet of the hot air generator 6 draws in air, and the outlet of the hot air generator 6 is connected to the inlet of the first gas filter 7. The outlet of the first gas filter 7 is connected to the first inlet of the gas heater 9. At the same time, the inlet of the steam heating valve group 8 draws in steam, and the outlet of the steam heating valve group 8 is connected to the second inlet of the gas heater 9. The air and steam form superheated steam in the gas heater 9, which is then delivered to the material continuous supply device 3 to achieve temperature regulation for steam sterilization.

[0034] Specifically, the outlet of the gas heater 9 is connected to the first switching valve 31, the second switching valve 32, the third switching valve 33, and the fourth switching valve 34, respectively. When superheated steam is supplied to the material continuous supply device 3, the third switching valve 33 opens, supplying the superheated steam to the lower cavity of the material continuous supply device 3. The steam heating valve group 8 is set to a temperature and the steam supply is controlled and adjusted according to a ratio of 140 to 145 degrees to maintain a stable steam supply temperature.

[0035] Based on the traditional Chinese medicine powder sterilization system provided in the above specific embodiments, the dehumidification and cooling device includes an auxiliary suction device 11, a blower 12, a dehumidifier 13, a second gas filter 14, and a liquid cooling coil 15. The discharge port at the bottom of the continuous material supply device 3 is connected to the material inlet of the auxiliary suction device 11. The blower 12, dehumidifier 13, and second gas filter 14 are connected in sequence. The second gas filter 14 is connected to the gas inlet of the auxiliary suction device 11. The material outlet of the auxiliary suction device 11 is connected to the inlet of the liquid cooling coil 15. The outlet of the liquid cooling coil 15 is connected to the filling device. The filling device is specifically a cyclone separator 16, and the lower end of the cyclone separator 16 is connected to a storage tank 17. The powder coming from the fourth switch valve 34 enters the auxiliary suction device 11. When the auxiliary suction device 11 is working, it uses air delivery pressure to suck in the powder and delivers the powder mixed with air to the liquid cooling coil 15. In order to supply sufficient air, the air is dehumidified and filtered by the blower 12, dehumidifier 13 and second gas filter 14. The treated air and the sterilized powder are simultaneously sucked into the auxiliary suction device 11 and delivered to the liquid cooling coil 15. After being cooled to the required temperature, it is filled.

[0036] The specific working process is as follows: The powder inside the automatic raw material supply device 1 is conveyed to the continuous material supply device 3 via the pressure suction device 2. During this process, the powder is intermittently conveyed into the continuous material supply device 3 by alternating the opening and closing of the first switching valve 31 and the second switching valve 32. The temperature of the sterilization chamber inside the continuous material supply device 3 is adjustable from 150 to 220°C. The sterilization temperature is regulated by the primary steam generator 4, the secondary steam generator 5, the steam heating valve group 8, and the gas heater 9. The sterilization time is adjusted by the rotation speed of the continuous material supply device 3, ranging from 3 to 15 seconds. The sterilization process is achieved through the jetting action of the steam nozzle. The material comes into full contact with the steam, and then the third switch valve 33 and the fourth switch valve 34 intermittently transport the material to the auxiliary suction device 11. The material continuous supply device 3 dehumidifies the internal air for the first time through cleanliness and high temperature. The fresh air that has been filtered, dehumidified and refrigerated is introduced into the auxiliary suction device 11, where the powder is dehumidified a second time and cooled at the same time. Then the powder enters the liquid cooling coil 15, where the powder is cooled a third time. Then the powder enters the cyclone separator. Through the centrifugal separation action of the cyclone separator, the gas is discharged from the top of the cyclone separator, and the powder is collected in the storage tank 17.

[0037] The above provides a detailed description of the traditional Chinese medicine powder sterilization system provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
