Different Types of Pressure Cookers

Posted by under Health , , ,

In the modern day fast-paced world where people do not have a lot of time to waste in the kitchen, pressure cookers add convenience and speed to cooking. Did I say speed? In fact, they prepare your meals at super-speeds, cutting down the cooking time by over 70%! It makes you wonder how they achieve such speedy cooking. The answer lies in some simple laws of physics which pressure cookers make use of to cook the food. By cooking the ingredients in a sealed container, they trap the steam that is produced when water heats up. Trapped steam results in an increased pressure which raises the boiling point of water. This means that the food will be cooked at a higher temperature than that involved in conventional cooking. Higher temperature cooks the meal much faster than the conventional approach.

Pressure cooking is not a new development. It has been around for centuries. However, it has seen much advancement over the centuries and the modern day pressure cookers are almost entirely different from the initial versions except for the basic principle. Here are the different types of pressure cookers classified according to their generations:

  1. First Generation

These are the traditional type of pressure cookers that come with limited functionalities and safety features. They have only one pressure mode and work on the technique of the weight bearing valve. This valve keeps a check on the pressure inside the cooker and release steam along with a lot of noise if the pressure goes beyond the required level.

  1. Second Generation

These second generation pressure cookers are the improved versions of the traditional ones where the weight bearing valves are replaced with spring loaded valves that are not visible from the outside. They allow you to select between multiple pressure options and set the spring to increase or decrease the pressure inside the cooker accordingly. They use an indicator to let you know when the pressure has reached the required level and only release steam when you open the lid or leave the cooker on the stove for too long.

  1. Electric Pressure Cookers

Electric pressure cookers, also called the third generation pressure cookers are the latest addition to the pressure cooker family. An internal heat source powered by electricity regulates the temperature and pressure inside the cooker. They have pre programmed settings to select between different cooking options and have multiple safety features to allow convenience of use. Programmed micro-chips installed on the inside of the cooker read and understand many data while the food is cooking to adjust the pressure automatically depending on the type and status of the food inside it.
