A microprocessor-controlled, self-contained steam sterilizer is disclosed. Once the steam exposure phase is complete in the sterilizer, the microprocessor is programmed to operate the vaporizing heater in a low-power duty cycle to utilize the vaporizing heater as a drying heater in a lower power operating mode to effect a drying phase.

Self-contained sterilizer with duty-cycle heater

The venting mechanism for discharging steam from a sterilizing chamber has a variable effective orifice area controllable in response to decreasing pressure. The throughput of the venting mechanism increases as the pressure decreases, thereby compressing the venting stage of a sterilization cycle without increasing the loss of liquid inherently experienced in sterilizing liquid loads.

Method and apparatus for venting sterilizers having a liquid load

An unplumbed sterilizer is provided with an exhaust valve means which allows automatic liquid introduction to the sterilizing chamber with the door closed even after a prior sterilization cycle has been run. The exhaust valve means also minimizes the possibility of trapping air within the chamber.
