Brief description of the working process
The working process is divided into five stages: airtightness detection of the cabin before sterilization, system preheating and dehumidification, microbial decontamination and sterilization, residue removal, and A-level laminar flow ventilation.
1. Check whether the airtightness of the cabin before sterilization can meet the sterilization function and whether the airtightness meets the requirements.
System leak rate detection - inflate the sterilization chamber to make the pressure in the chamber reach the set value, maintain the pressure, and the leakage amount is not greater than the specified value within the set time, indicating that the system is in good condition and can enter the sterilization process.
2. The system is preheated and dehumidified - clean and dry air is sent into the cabin to keep the humidity in the cabin at a low value, which is conducive to hydrogen peroxide sterilization.
3. Sterilization procedure - input hydrogen peroxide vapor into the sterilization chamber, and maintain the expected concentration of the sterilization chamber, keep the VHP concentration above the set concentration, and keep the sterilization time for more than 30-60min (requires chemical test paper and Biological test strip verification);
4. Residue removal - stop the input of hydrogen peroxide vapor, switch the sterilization system to the residue removal system, make the hydrogen peroxide gas in the sterilization chamber circulate through the catalytic converter for decomposition, quickly reduce the concentration of hydrogen peroxide, and then ventilate to remove the residue. The residual hydrogen peroxide is below 1PPM.
5. A-level laminar flow - the air supply fan is turned on, and the fresh air valve and the exhaust valve are adjusted to keep the pressure difference between the cabin and the high-grade cabin outside the cabin greater than 10Pa. The airflow can be either horizontal unidirectional flow or vertical unidirectional flow. After the sterilization and removal of residues are completed, the cabin maintains a laminar flow state. After the high-level side door is opened, the cabin is still in a laminar flow state.
