Publish Time: 2024-10-22
The application of the fully automatic high pressure steam sterilizer in the pharmaceutical industry is crucial to ensure the sterility of drugs and laboratory equipment. In order to precisely control the sterilization time and humidity, the high pressure steam sterilizer adopts a series of advanced technologies and systems.
1. Temperature and pressure sensing technology
High-precision sensors: The sterilizer is equipped with high-precision temperature and pressure sensors, which can monitor the temperature and pressure in the chamber in real time. Common sensors include thermocouples and resistance thermometers (RTDs), which can provide very accurate data.
Real-time data feedback: The data collected by the sensor will be fed back in real time through the control system to ensure that the temperature and pressure during the sterilization process are in accordance with the preset values. If there is a deviation, the system can be adjusted in time.
2. Control system
Microprocessor control: Modern sterilizers usually use advanced microprocessor control systems, which can accurately control various parameters in the sterilization process, including temperature, pressure, humidity and time.
Custom programs: Users can customize different sterilization programs according to different sterilization needs. The control system will strictly follow these procedures to ensure that the required sterilization conditions are met.
3. Humidity control
Steam generation system: The sterilizer generates high-pressure wet steam through a steam generator. The humidity control is mainly achieved by accurately adjusting the working parameters of the steam generator.
Humidity sensor: A humidity sensor is installed inside the sterilizer to monitor the humidity level in the cavity in real time. The control system adjusts the steam supply according to the data of the humidity sensor to maintain the set humidity level.
Condensate discharge system: Excessive condensate in the cavity will affect the humidity control, so the sterilizer is equipped with an efficient condensate discharge system to ensure the stability of the humidity in the cavity.
4. Time control
Preset sterilization time: The user can preset the total sterilization time according to the sterilization object and requirements. The control system will strictly follow the preset time to ensure the integrity of the sterilization process.
Staged control: The sterilization process is usually divided into multiple stages, including preheating, heating, constant temperature, cooling, etc. The control system can accurately control the start and end time and parameters of each stage to ensure the sterilization effect.
5. Safety Assurance System
Multiple safety valves: The sterilizer is equipped with multiple safety valves to prevent the pressure from exceeding the safety limit. If the system detects abnormal pressure, the safety valve can open quickly to release the pressure and protect the equipment and operators.
Emergency stop button: In an emergency, the operator can immediately stop the sterilization process through the emergency stop button to protect the equipment and reduce risks.
6. Data recording and monitoring
Data recording system: The control system records key parameters such as temperature, pressure, humidity and time data throughout the sterilization process. These data can be exported and used for verification and auditing.
Monitoring panel: The sterilizer is usually equipped with a large-screen monitoring panel, and the operator can view the sterilization status and various parameters in real time, which is convenient for timely adjustment and operation.
Fully Automatic High Pressure Steam Sterilizer ensures precise control of temperature, pressure, humidity and time during the sterilization process by adopting advanced temperature and pressure sensing technology, precise control system, humidity adjustment system and time control function. These advanced technologies and systems not only improve the reliability of sterilization effect, but also reduce operational risks, ensure the sterility of drugs and medical devices, and meet the strict requirements of the pharmaceutical industry.
