Recently, the vaccine incident has escalated and the origin of the vaccine has attracted everyone's attention. What is the vaccine production process? How many automated machines are used, and why do they keep having problems?
Viral vaccines need to be sent to a quality control laboratory for testing after being cultured for attenuation testing to confirm compliance with various standards, including vaccine effectiveness, purity, and safety.
The positive pressure ventilation system of the absolute filter in the laboratory (breeding farms, factories, etc. should also be matched) to ensure the absolute sterility of the laboratory environment.
The ventilation system adopts PLC control system control
1. Electrical equipment should be interlocked with the ventilation system. Ventilation must be done before operation, and the main power supply of the electrical equipment should be connected when the ventilation volume is greater than 5 times the volume of the electrical equipment and its ventilation system. Gumei CX3G series PLC can collect the current wind speed through the wind speed sensor and calculate the air volume to ensure that the ventilation meets the requirements before starting the electrical equipment;
2. During operation, the gas entering the electrical equipment and its ventilation system should not contain flammable substances or other harmful substances. PLC can collect data from the gas sensor, and immediately stop the operation of the equipment once it finds flammable or other harmful substances;
3. During the operation of electrical equipment and its ventilation system, the air pressure should not be lower than 50Pa. When the air pressure is lower than 50Pa, the PLC can automatically disconnect the main power supply of the electrical equipment or issue an alarm signal;
4. Electrical equipment must have one or more inlet and outlet ports connected to the ventilation system. The exhaust port must be properly sealed after ventilation. CX3G-64MR can control the exhaust port to automatically close after the end of ventilation.
For each batch of vaccine products, only after the sample is approved can it leave the production unit. New products will also be tested on site in accordance with the requirements of various international organizations.
The filling of the vaccine is carried out in a sterile environment. The air in the environment is sterilized and filtered to maintain a positive pressure.
Firstly, the vaccine bottle is sterilized by distillation and high temperature drying. The control system adopts Gumei PLC control system, which has stable and reliable performance and no electromagnetic interference. MT9070KH LCD touch screen displays and operates, and parameters can be set at will; high degree of automation, hot Water, brush, distilled water and other cleaning, disinfection, and drying automatic processing functions are integrated, which can automatically and continuously perform bottle washing operations.
Subcontracting pipeline
Finally, the vaccine enters the subcontracting assembly line, and the equipment contains sensors to detect the quantity and weight of the vaccine. When the detected data is incorrect, the PLC will control the machine to automatically sort out the problematic vaccines. If there is no problem, enter the next process. , The subcontracting ends. Finally, the vaccine is delivered to the user through refrigerated transportation.
In addition to the vaccine production company’s own problems, the government also has loopholes in the supervision and punishment of vaccines. Therefore, it is difficult to rule out the production of ineffective vaccines even if automated machinery is used.
