Ethylene oxide sterilizer is a special equipment that uses ethylene oxide gas to sterilize items closed in the sterilization chamber under a certain temperature, pressure, and humidity. The sterilizer is generally composed of a sterilization box, an auxiliary rack (cabinet), an electrical control cabinet and a computer. Specifically, it can be divided into sterilization room, vacuum system, thermal cycle system, dosing system, door and sealing system, residual gas treatment system, electrical control system and computer detection and management system.
The sterilization effect of ethylene oxide is related to the temperature, pressure, humidity and concentration of ethylene oxide in the sterilization chamber. Controlling these parameters at appropriate values ​​can shorten the sterilization time and achieve the best sterilization effect. Therefore, the process of the sterilizer operation first heats the sterilization chamber until the temperature reaches the sterilization temperature. Then, the sterilization chamber is evacuated, and when the vacuum reaches the required value of the pre-vacuum, the sterilization chamber starts to humidify and dosing.
After the above process is completed, watch the clock and start the sterilization process. Maintain a constant temperature throughout the sterilization process. When the punctuality is up, the sterilization chamber will be ventilated, that is, the filtered clean air will be used to replace the remaining air in the sterilization chamber. After several repetitions, the residual air is drained. The residual gas is discharged after discarding the treatment system. So far the whole process is complete
