Description

Technical Field

[0002] Sterilization is an essential technology in the pharmaceutical field to ensure drug safety. In the pharmaceutical industry, drug raw materials must be sterilized and meet usage requirements before they can comply with safe production standards.

[0003] Conventional methods for sterilizing medicinal materials utilize high temperature and negative pressure to create a sterilization environment. For example, Chinese utility model patent application number CN201620405860.8, entitled "A Fully Automatic Moist Heat Sterilizer," includes a sterilizer tank and a top cover thereon. A jacket is provided on the outer side of the sterilizer tank, forming a space between the jacket and the sterilizer tank. A vacuum valve, a water inlet valve, and a water outlet valve are connected to the jacket, and these valves are respectively connected to the space. A heating device is provided on the inner wall of the sterilizer tank. Inside the sterilizer tank, a ribbon agitator consisting of a stirring shaft and a spiral band fixed to the stirring shaft is installed. The upper part of the stirring shaft is located outside the sterilizer tank and connected to a drive motor. Water is usually circulated inside the sterilizer tank to help heat the materials. However, because the raw powder of Chinese medicinal materials cannot come into contact with water or be wetted by water, and because of the influence of the boiling point of water, the temperature inside the tank cannot reach a high temperature, which will lead to poor sterilization effect.

[0004] Therefore, there is an urgent need for a sterilization device for Chinese medicinal materials to solve the problem that the sterilization effect is poor because the raw powder of Chinese medicinal materials cannot come into contact with water or is wetted, and is affected by the low boiling point of water, which makes it impossible to reach the ideal temperature inside the tank.

This device purifies water vapor within the tank 1, preventing water from contacting the raw Chinese medicinal materials and preventing the materials from becoming wet. Simultaneously, it utilizes a negative pressure pump 2 and a heating device to create a waterless, negative pressure, and high-temperature environment for the materials to be sterilized within the tank 1, ensuring that the tank 1 reaches the ideal sterilization temperature and improving the sterilization effect.

[0045] It should be noted that the sterilization device for Chinese medicinal materials described in this utility model is used in, but not limited to, the field of biological sterilization technology. For ease of explanation, this utility model only uses the application of the sterilization device for Chinese medicinal materials in the field of biological sterilization technology as an example for explanation. The principle of the sterilization device for Chinese medicinal materials applied to other types of equipment is essentially the same as the principle applied to the field of biological sterilization technology, and will not be described in detail here.

[0046] Please see Figure 1 , Figure 2 , Figure 1 , Figure 2This is a schematic diagram of the structure of a sterilization device for traditional Chinese medicine materials according to an embodiment of the present invention. The sterilization device for traditional Chinese medicine materials includes: a tank body 1, a negative pressure pump 2, at least one heating component 3, a steam generating component 4, and a crushing component 5. The tank body 1 is hollow inside and has an inlet, an exhaust port, and an outlet connected to its interior. The air inlet of the negative pressure pump 2 is connected to the interior of the tank body 1 through the exhaust port. The heating component 3 is connected to the tank body 1. The steam generating component 4 includes a purified water steam generator 41. The exhaust port of the purified water steam generator 41 is connected to the interior of the tank body 1 through the air inlet. The crushing component 5 is connected to the interior of the tank body 1 through the outlet.

[0047] In this device, the tank 1 is provided with an inlet, an exhaust port, and an outlet that are connected to its interior. The inlet is used to feed the material to be sterilized into the tank 1. The air inlet of the negative pressure pump 2 is connected to the interior of the tank 1 through the exhaust port to create a negative pressure environment inside the tank 1. The crushing component 5 is connected to the interior of the tank 1 through the outlet to crush the sterilized material. The heating device is connected to the tank 1 to heat the tank 1 and the material to be sterilized inside the tank 1. The exhaust port of the purified water vapor generator 41 is connected to the interior of the tank 1 through the air inlet to purify water vapor into the tank 1.

[0048] Compared to existing technologies, this method purifies water vapor inside the tank 1, preventing water from contacting the raw powder of Chinese medicinal herbs and avoiding wetting the herbs. At the same time, it uses a negative pressure pump 2 and a heating device to create a waterless, negative pressure, and high-temperature environment for the materials to be sterilized inside the tank 1, allowing the temperature of the tank 1 to reach the ideal sterilization state and improving the sterilization effect. This method solves the technical problem in existing technologies where the raw powder of Chinese medicinal herbs cannot come into contact with water or become wet, and the low boiling point of water prevents the temperature inside the tank from reaching the ideal state, resulting in poor sterilization effect.

[0049] Furthermore, the negative pressure pump 2 here is a common and readily available negative pressure device on the market, which can create a negative pressure environment inside the tank 1. The purified water vapor generator 41 here is a common and readily available steam generator on the market, which can convert purified water into purified water vapor. Here, the high temperature carried by the purified water vapor is used in conjunction with the negative pressure pump 2 to create a waterless, negative pressure and high temperature environment inside the tank 1, which can achieve the ideal sterilization effect. The negative pressure pump 2 and the purified water vapor generator 41 are both conventional settings known to those skilled in the art, and will not be described in detail here.

[0050] In this embodiment, as Figure 1 , Figure 2As shown, the tank 1 includes a shell 11, a cover 12, and a linear drive unit 13. The shell 11 has an interior and an opening at the top. The cover 12 is hinged to one side of the opening end of the shell 11. The linear drive unit 13 has a fixed end and an extended end. The fixed end of the linear drive unit 13 is hinged to the outer wall of the shell 11, and the extended end is hinged to the cover 12. It is used to drive the cover 12 to rotate relative to the shell 11 to block or open the opening of the shell 11.

[0051] Driven by the linear drive unit 13, the cover 12 can rotate relative to the housing 11, and the rotated cover 12 can seal or open the opening end of the housing 11.

[0052] Furthermore, the linear drive unit 13 here is a cylinder, push rod motor or hydraulic cylinder that is common and readily available in the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0053] In one embodiment, please refer to Figure 1 , Figure 2 The circumferential sidewall of the housing 11 forms a sandwich space 14, and at least one heating component 3 is built into the sandwich space 14 and connected to the housing 11.

[0055] In this embodiment, as Figure 1 , Figure 2 As shown, the steam generating assembly 4 also includes a first connecting pipe 42 and a spray head 43, a heater 44, and a second connecting pipe 45.

[0056] One end of the first connecting pipe 42 is built into the tank 1, and the other end is connected to the outlet of the purified water vapor generator 41. The spray head 43 is built into the tank 1 and connected to the other end of the first connecting pipe 42.

[0057] The steam generated by the purified water steam generator 41 is evenly sprayed into the housing 11 through the first connecting pipe 42 and the spray head 43, which can efficiently contact the material to be sterilized.

[0058] In one embodiment, please refer to Figure 1 , Figure 2 The heater 44 is located between one end of the spray head 43 and the first connecting pipe 42, and is connected to both one end of the spray head 43 and the first connecting pipe 42.

[0059] The heater 44 is located between the connecting pipe and the spray head 43, which can reheat the steam that is introduced into the spray head 43 through the connecting pipe, prevent the steam from forming condensate at the end of the connecting pipe or the spray head 43, and improve the sterilization effect.

[0060] Furthermore, the heater 44 here is a common and readily available device on the market. It is connected to one end of the connecting pipe and is used to reheat the steam entering the connecting pipe. The heater 44 here is a conventional setting known to those skilled in the art, and will not be described in detail.

[0061] In one embodiment, please refer to Figure 1 , Figure 2 One end of the second connecting pipe 45 is connected to the outlet of the purified water vapor generator 41, and the other end is connected to the interlayer space 14.

[0062] The outlet of the purified water steam generator 41 is connected to the interior of the interlayer space 14 via the second connection end, which enables the use of steam to quickly cool down the heating component 3 and the tank 1 after sterilization, thereby reducing cooling time and improving production efficiency.

[0063] In this embodiment, as Figure 1 , Figure 2 As shown, it also includes a stirring assembly 6, which is built into the housing 11.

[0064] The stirring component 6 is built into the shell 11 and can rotate relative to the inner wall of the shell 11. It has stirring and mixing functions, which can improve the contact between the material and the interlayer space 14 of the shell 11 or the heating component 3, thereby improving the efficiency of heat transfer and production efficiency.

[0065] Furthermore, the stirring component 6 here is a common and readily available piece of equipment on the market, and is a conventional setup known to those skilled in the art, so it will not be described in detail here.

[0066] In this embodiment, as Figure 1 , Figure 2 As shown, both the feed inlet and the air extraction port are located on the cover 12, and the cover 12 is also provided with an air inlet. One end of the first connecting pipe 42 is connected to the interior of the housing 11 through the air inlet.

[0067] The feed inlet, the exhaust port, and the air inlet are all located on the cover 12, which respectively realize the functions of feeding, exhausting and purifying water vapor.

[0068] In one embodiment, please refer to Figure 1 , Figure 2 The cover 12 is also provided with a liquid inlet 15 for introducing clean water and cleaning the inside of the housing 11.

[0069] The cover 12 is also provided with a liquid inlet 15. After the sterilization process is completed, clean water needs to be introduced into the interior of the shell 11 to clean the interior of the shell 11.

[0070] In this embodiment, as Figure 1 , Figure 2 As shown, the device also includes a control panel 7, which is electrically connected to the negative pressure pump 2, the purified water steam generator 41, the heater 44, the spray head 43, the stirring assembly 6, and the linear drive unit 13.

[0071] The control panel 7 is electrically connected to the negative pressure pump 2, the purified water steam generator 41, the heater 44, the spray head 43, the stirring assembly 6, and the linear drive unit 13, enabling automated and intelligent settings.

[0072] Furthermore, the control panel 7 here is a common and readily available PLC controller on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0073] To better understand this utility model, the following is combined with... Figure 1 , Figure 2 The technical solution of this utility model is described in detail below:

[0074] The tank 1 has an inlet, an exhaust port, and an outlet connected to its interior. The inlet is used to feed the material to be sterilized into the tank 1. The air inlet of the negative pressure pump 2 is connected to the interior of the tank 1 via the exhaust port to create a negative pressure environment inside the tank 1. The crushing component 5 is connected to the interior of the tank 1 via the outlet to crush the sterilized material. A heating device is connected to the tank 1 to heat the tank 1 and the material to be sterilized inside. The exhaust port of the purified water vapor generator 41 is connected to the interior of the tank 1 via the air inlet to purify water vapor into the tank 1. Compared with the prior art, by introducing high-temperature purified water vapor into the tank 1, water is prevented from contacting the raw powder of Chinese medicinal materials and the Chinese medicinal materials are prevented from being wetted. At the same time, the negative pressure pump 2 and the heating device create a waterless, negative pressure, and high-temperature environment for the material to be sterilized in the tank 1, so that the temperature of the tank 1 reaches the ideal sterilization state, thus improving the sterilization effect.

[0075] In the specific working process of this utility model, the shell 11 is first cleaned, dried and cooled, and then the cover 12 is placed on top. The jacket is heated to 98°C, and then the negative pressure pump 2 is started to draw a vacuum to above 0.094 MPa. The material is then drawn into the shell 11 through the negative pressure environment, and the stirring component 6 inside the shell 11 stirs it. Then, when the designed sterilization temperature of the material inside the shell 11 reaches 121°C, the vacuum is drawn to above 0.094 MPa to form a negative pressure. Then, the shell 11 is evacuated again to above 0.094 MPa to form a negative pressure. The purified water steam generator 41 is used to process the steam and it is atomized and added into the shell 11 through the spray head 43 until the internal and external pressures of the cavity are balanced, and then the addition of steam is stopped. The heating component 3 in the jacket space heats, dries, and stirs for 30 minutes; finally, the operation is repeated twice, and the shell 11 is evacuated to a negative pressure of over 0.094 MPa. The purified water steam generator 41 processes the steam and atomizes it through the spray head 43 before adding steam into the shell 11 until the internal and external pressures are balanced, then the addition of steam is stopped. The heating component 3 in the jacket space heats, dries, and stirs for 30 minutes.

[0076] Furthermore, after the material is sterilized, it is treated by the purified water steam generator 41 and the steam is introduced into the jacket space 14 through the second connecting pipe 45 to cool the heating component 3 and the shell 11 to about 45°C before being discharged. The material enters the crushing component 5 through the discharge port and is crushed by the speed-adjustable pulverizer before being discharged.

[0077] This device, through the aforementioned structure, can solve the technical problem in the prior art where the temperature inside the tank cannot reach the ideal state due to the inability of the raw powder of Chinese medicinal materials to come into contact with water or to be wetted, and the influence of the low boiling point of water, resulting in poor sterilization effect.

[0078] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
