This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave, sometimes called a converter or steam sterilizer. The object or liquid is placed in the autoclave chamber, which is then sealed and heated using pressurized steam to a temperature set point for a defined period of time.
Sterilization can also be achieved using ethylene oxide (ETO) gas. This process was created in the 1950s by the US military [4] and is used on items that cannot withstand the high temperatures of steam sterilization. ETO sterilization takes far longer than steam sterilization and is hazardous to workers, so alternative methods were created in ...
Steam at 134 °C (273 °F) can achieve a desired level of sterility in three minutes, while achieving the same level of sterility in hot air requires two hours at 160 °C (320 °F). [11] Methods of air removal include: Downward displacement (or gravity-type): As steam enters the chamber, it fills the upper areas first as it is less dense than air.
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
A waste converter is a machine used for the treatment and recycling of solid and liquid refuse material. A converter is a self-contained system capable of performing the following functions: pasteurization of organic waste; sterilization of pathogenic or biohazard waste; grinding and pulverization of refuse into unrecognizable output; trash compaction; dehydration.
Koch's or Arnold's steam sterilizer: used for steam sterilization A pressure cooker: used as a portable autoclave Biological and chemical indicators: Used to ascertain if a certain process has been completed, e.g. spores used in an autoclave are killed if autoclaving is properly done Filters: •Candle filter:
Tyndallization is a process from the nineteenth century for sterilizing substances, usually food, named after its inventor John Tyndall, that can be used to kill heat-resistant endospores. Although now considered dated, it is still occasionally used. [citation needed]
Steam is used across multiple industries for its ability to transfer heat to drive chemical reactions, sterilize or disinfect objects and to maintain constant temperatures. In the lumber industry, steam is used in the process of wood bending, killing insects, and increasing plasticity. Steam is used to accentuate drying of concrete especially ...
