2. EXPLANATION OF THE AUTOCLAVE
2-1. Operating Principle
The high-pressure steam sterilizer is a autoclave used for sterilizing articles with saturated
steam under a pressure which is higher than atmospheric pressure.
After commencement of operation, sterilizing water in the chamber is heated by the element
heater at the bottom of the chamber to generate steam. Steam generated through heating drives
air from the chamber and warms the inside of the chamber. When the temperature sensor
in the chamber detects that the temperature has risen to the specified level, this temperature
is maintained for a specified time. Residual air in the chamber is driven out through this
operation. When the specified time has elapsed, the valve closes to carry out heating.
When the temperature sensor detects that the temperature has risen to the specified level,
the timer is activated to maintain a constant temperature. When the set sterilizing time has
elapsed, the element heater stops. The sterilizing action is determined by the three elements:
temperature, humidity, and time applied to articles to be sterilized during this time.
When the temperature in the chamber falls, the valve opens to return the pressure in the
chamber to the atmospheric level. When the temperature sensor detects 60 °C, all processes are
completed and completion is indicated by a buzzer sounding and by the indication lamp.
When an abnormality is generated in the autoclave, it changes to a safer status and the
abnormality is indicated by an error code display and by a buzzer sounding.
