Скачать или смотреть How Does A PRESSURE COOKER Work

A pressure cooker is a cooking appliance that utilizes steam pressure to cook food quickly. Here's how it works:

Sealed Container: A pressure cooker consists of a sealed cooking pot (usually made of stainless steel or aluminum) with a locking lid. The lid typically has a rubber or silicone gasket to create an airtight seal.

Liquid and Steam: When food and liquid are placed inside the pressure cooker and heat is applied, the liquid (usually water or broth) begins to boil and produce steam.

Increased Pressure: As the liquid boils, it creates steam, which increases the pressure inside the sealed container. The pressure builds up because the steam cannot escape the tightly sealed pot.

Higher Boiling Point: The pressure inside the cooker raises the boiling point of the liquid. This means that the food cooks at a higher temperature than it would in a normal open pot, allowing for faster cooking times.

Faster Cooking: The higher temperature and pressure inside the cooker speed up the cooking process significantly. Tough cuts of meat, grains, beans, and other foods that typically require long cooking times can be cooked in a fraction of the time in a pressure cooker.

Safety Features: Modern pressure cookers are equipped with safety features to prevent accidents due to excessive pressure buildup. These features may include pressure release valves, locking mechanisms, and backup pressure release systems.

Natural Release or Quick Release: After cooking is complete, the pressure inside the cooker needs to be released before opening the lid. This can be done through natural release (allowing the pressure to decrease gradually) or quick release (manually releasing the pressure using a valve).

In summary, a pressure cooker cooks food quickly by using steam pressure to raise the temperature inside a sealed container. This allows for faster cooking times and tenderizes tough ingredients more effectively compared to traditional cooking methods.
