In order to meet the relevant requirements of effectively improving the pretreated products before ethylene oxide sterilization to reach the predetermined temperature and relative humidity. Our company designs the corresponding preheating room scheme: using circulating water radiator system, using rock wool self-extinguishing colored steel plate to build a relatively airtight space, and adopting efficient and energy-saving hot air internal circulation system to keep the corresponding temperature (above 45 ℃) and corresponding humidity (above 40%RH) in the preheating room uniformly, ensuring effective pretreatment and saving energy consumption within the target time. The whole process is automatically controlled by professional industrial control computer + SIMENS PLC, and the heating temperature is adjusted and controlled by PID. Heating temperature, humidity control, internal circulation fan start and stop time and other parameters can be set as needed, the whole process is recorded and archived by the computer, and can be called, viewed and printed at any time.
In order to meet the relevant requirements of effectively reducing ethylene oxide residues in articles after ethylene oxide sterilization. Our company designs the corresponding analysis room scheme: making use of the relatively active chemical properties of ethylene oxide gas molecules at a suitable temperature. We use the hot air circulation system with high efficiency and energy saving in the relatively confined space to maintain the corresponding temperature (above 30 ℃) of the products in the analytical room, and cooperate with the latest American analytical process to regularly discharge the residual gas and supplement the filtered air. to the maximum extent possible to ensure the effectiveness of the analysis and save energy consumption within the target time. The whole process is automatically controlled by professional industrial control computer + SIMENS PLC, and the heating temperature is adjusted and controlled by PID. The temperature in the room, the start and stop time of internal and external fans and other parameters can be set as needed, and the whole process can be recorded and archived by computer, which can be called, viewed and printed at any time. According to the American FDA recommended analytical process: set the analytical temperature to be controlled at 30mi 50 ℃; with exhaust air, air supply system (air exchange) function, air exchange time and frequency can be controlled. The analysis cycle is related to many factors, such as product packaging, sterilization process, the degree of cleaning in the sterilizer, the process parameters used in the analysis room, etc., or need to be determined by the final residue test, which can not be generalized.
