The working principle of a fully automatic sterilizer is primarily based on the concept of high-temperature sterilization. It creates a high-temperature and high-pressure environment through a sealed pot body. First, the items to be sterilized are placed inside the pot, and the lid is sealed. Then, the heating device rapidly raises the temperature inside the pot, typically reaching around 121°C. The high temperature effectively kills microorganisms such as bacteria and spores. Meanwhile, the pressure inside the pot increases accordingly, enhancing the sterilization effect. During the sterilization process, the temperature and pressure inside the pot are monitored and controlled in real-time by sensors to ensure precision and stability of the sterilization conditions. After sterilization is completed, the cooling device rapidly reduces the temperature and pressure, ensuring the quality and safety of the items.
