Yes, it is normal for a pressure cooker to produce steam during operation. A pressure cooker uses high pressure and temperature to cook food quickly. As the liquid inside the pressure cooker reaches its boiling point, it produces steam, which is essential for building and maintaining the pressure within the cooker. The steam helps increase the internal pressure, which in turn raises the boiling point of the liquid, allowing food to cook faster.
To ensure safe operation, pressure cookers are equipped with a pressure release valve or a pressure regulator. This valve helps regulate the pressure inside the cooker by releasing excess steam when necessary. It's important to follow the manufacturer's instructions and safety guidelines for your specific pressure cooker model to prevent any accidents or mishaps while using it.
