Introduction of pressure steam sterilizer
Pressure steam sterilizer is a kind of equipment that uses saturated pressure steam to sterilize articles quickly and reliably. It can sterilize medical instruments, dressings, glassware, solution culture media, etc. It is considered as one of the most reliable disinfection technologies in the world.
Pressure steam sterilizer has a long history, with a history of 100 years. Commonly used in food processing enterprises, hospitals at all levels, centers for disease control and prevention, inspection and quarantine institutions and other enterprises and institutions, widely used.
Second, the principle of pressure steam sterilizer
High pressure steam sterilizer consists of sterilization chamber, control system and overpressure protection device. Protein denaturation of microorganisms is the use of high-temperature saturated steam to cause the death of microorganisms in a certain period of time, so as to achieve the purpose of sterilization of moisture-resistant and heat-resistant articles.
Because steam can't overflow in a closed steamer, the boiling point of water will increase with the increase of pressure, so the temperature in the boiler will also increase. At the pressure of 0. 1MPa, the temperature in the boiler can reach 12 1℃. At this steam temperature, all kinds of bacteria can be killed quickly.
Characteristics of pressure steam sterilizer
I. Structure of sterilizer
The main body of the sterilizer is a horizontal rectangular structure with a reinforced jacket. There are electric heating type and external steam type. Imported SUS304 stainless steel is used for the inner liner of the sterilization chamber, and stainless steel grinding plate is used for the external decoration.
Second, the sealing method
The sealing method is silicone rubber sealing, and the sealing surface is made of stainless steel, which maximizes the service life of the sterilizer. This product has a safety interlock device, which meets the mandatory requirements of capacity regulations. When there is pressure in the cabinet, the sealed door cannot be opened, and there is an audible and visual indication to ensure the safety of operation.
Thirdly, the LED ensures the automatic operation of the whole machine.
Intelligent controller and PLC (programmable controller) are used to automatically control the whole sterilization process. The temperature and time parameters are designed by ourselves, and the reliable and automatic operation of the whole machine is ensured by the automatic digital display of ultra-bright LED.
Fourthly, the forced vacuum exhaust method is adopted.
Pulsating vacuum adopts forced evacuation and exhaust to ensure that the cold air in the sterilization room is completely eliminated. Vacuum dehumidification and interlayer drying ensure the drying and cleaning of sterilized items. Adopt automatic and manual control mode, double control of pressure and temperature.
