Structural principle of rubber stopper cleaning rotary sterilization box
Date: 2025-04-29Read: 34
The structural principle of the rubber plug cleaning rotary sterilization box can be divided into two parts: mechanical structure and workflow. The comprehensive search results analysis is as follows:
1、 Mechanical structure composition
1. Rotary drum system
Sterilization cylinder: Designed with a porous structure, it facilitates the penetration of cleaning media and hot air through the rubber plug layer. The cylinder is driven by a servo motor to achieve uniform rotation of the gear set, ensuring that the rubber plug is dynamically and uniformly heated or in contact with the cleaning medium.
Support and drive components: including groove guide rails, support wheels, and limit devices to ensure the stability of cylinder operation; The gear ring cooperates with the transmission gear to provide power and reduce wear.
2. Cleaning module
Spray system: Use high-pressure water flow or specialized cleaning agents to remove dirt from the surface of the rubber plug, and the spray head covers the entire cylinder area.
Vacuum defoaming device: using negative pressure environment to peel off the surface bubbles of the rubber plug, allowing the attached particles to be discharged with the water flow.
Soda impact device: By using high-speed airflow to change the direction of rubber plug movement, vibration is used to peel off surface impurities, combined with eddy current to enhance cleaning effect.
3. Sterilization and drying module
Heating system: using electric heating or high-temperature steam, combined with high-temperature resistant and efficient air filters, to form a uniform hot air flow.
Drying room: Integrated hot air circulation system, directional airflow quickly evaporates residual moisture, avoiding sterilization interference.
Moisture removal and air intake system: operate alternately at regular intervals to maintain a constant temperature and positive pressure environment inside the box, discharge water vapor, and supplement filtered air.
4. Control system
PLC programmable controller: supports parameter settings such as temperature, time, and speed, achieving automated switching of cleaning, drying, and sterilization processes.
Human machine interface: The touch screen monitors the real-time operating status (such as temperature, pressure, speed, etc.) and provides sound and light prompts.
5. Security system
Multiple protection devices: including over temperature protection, water shortage alarm, abnormal shutdown, etc., to ensure the safe operation of the equipment.
Cabin door interlock: automatically locked when sterilization is not completed, unlocked when temperature meets the standard.
2、 Working principle and process
1. Cleaning stage
After the rubber plug is installed in the rotary drum, the spray system starts high-pressure water flow flushing, while vacuum defoaming or steam water impact technology assists in removing deep-seated pollutants.
Impurities are discharged through the drainage system, and the cleaning solution can be circulated and filtered for use.
2. Drying stage
The hot air circulation system is activated, and the directional airflow carries away the surface and pore moisture of the rubber plug, ensuring no residue before sterilization.
3. Sterilization stage
The heating system heats up to the set value (dry heat or high-temperature steam), and the filtered hot air evenly penetrates the rubber plug layer to kill microorganisms.
The internal circulation fan maintains positive pressure, and the microporous regulating plate ensures uniform airflow distribution; Operate alternately with timed dehumidification and air intake to maintain a constant temperature.
4. Cooling and discharge
After sterilization, the cooling system reduces the temperature inside the cylinder to prevent thermal deformation of the rubber plug.
PLC control automatically unlocks the cabin door, and the conveyor system sends out the rubber plug.
3、 Core design features
1. Integrated cleaning, drying, and sterilization functions are centralized, reducing manual intervention.
2. Advantages of dynamic processing: The rotating drum improves cleaning and sterilization efficiency, avoiding static dead corners.
3. Environmental protection and energy conservation: The circulating filtration system reduces the consumption of water, electricity, and cleaning agents.
This equipment combines precision mechanical structure with automation control to meet the high cleanliness and sterilization requirements of the pharmaceutical industry for rubber stopper processing.
