AI Technical Summary

Technical Problem

During the cooling phase of a vertical pressure steam sterilizer, the drain valve is open for a fixed duration, resulting in incomplete wastewater discharge or the release of a large amount of high-temperature steam, which affects cooling efficiency.

Method used

By acquiring the current stage information of the steam sterilizer, the exhaust and drainage strategies are determined based on real-time temperature and pressure values. The discharge volume of high-temperature steam and wastewater is dynamically adjusted, and the opening duration of the exhaust valve and drainage valve is controlled by the processor.

Benefits of technology

It enables precise discharge of high-temperature steam and wastewater, improves cooling efficiency during the cooling stage, and reduces safety hazards.

Abstract

This application relates to the field of steam sterilizer technology, and discloses a cooling method for a steam sterilizer, comprising: when the steam sterilizer is in the cooling stage, acquiring the current stage information of the steam sterilizer; if the current stage information indicates that it is in the pre-depressurization stage, determining the exhaust strategy of the exhaust pipe based on the real-time temperature and real-time pressure values ​​to adjust the amount of high-temperature steam discharged to the exhaust pipe; if the current stage information indicates that it is in the pressure drainage stage, determining the drainage strategy of the drainage pipe based on wastewater information to achieve dynamic drainage. This method can achieve precise discharge of high-temperature steam and wastewater in the cooling stage, improving the cooling efficiency of the cooling stage. This application also discloses a cooling device for a steam sterilizer, as well as a steam sterilizer and a medium.
