Steam Sterilization Disinfection Sterilization ...

18/09/2016  The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Thus, there are four parameters of steam sterilization: steam, pressure, temperature, and time. The ideal steam for sterilization is dry saturated steam and entrained water (dryness fraction ≥97%).

Steam Sterilization Principles - ISPE

steam sterilizer dries the load after sterilization by drawing a deep vacuum in the chamber (post- conditioning phase). A vacuum level of 1.0 to 2.0 psia (6.9 to 13.8 kPa) is recom- mended for efficient drying. At 1.0 psia (6.9 kPa) chamber pressure, water boils at 38.7°C (101.7°F). Therefore, the condensate will boil and be removed as steam through the sterilizer’s vacuum system. The ...

Thermal Processing for Food Sterilization and Preservation

01/01/2019  Thermal processing consists of heating food containers in pressurized retorts (steam autoclaves or “pressure cookers”) at specified temperatures for prescribed lengths of time. These process times are calculated on the basis of achieving sufficient bacterial inactivation in each container to assure food safety to the consuming public, and to ensure that the probability of spoilage will be ...

SAFETY GUIDELINES FOR AUTOCLAVES - Surdry

Surdry autoclaves, besides pressure gauges installed in the vessel, have a safety locking system that prevents from opening the door if any residual energy is stored within the vessel. When pulling back the pin to unlatch the door, a valve connected mechanically to such pin is opened. If any water or steam/air under pressure is seen through such valve, you must not turn the wheel.
