Types of pressure cookers

Almost all pressure cookers, whether conventional or modern follow the same theory. They increase the internal pressure of the water more than the boiling point. This results in faster and a healthier cooking experience. High-pressure wet steam is the most significant factor for transferring heat to cook the meal effectively and rapidly.

Pressure cookers vary according to its generations, which further divide into subcategories based on their features.

  •    First generation

First generation pressure cookers are the old type that operates with a weight-modified valve. The cooker sounds like whistles when the pressure releases through the valve. People find this version of pressure cooker very loud because the pressure of the valve is very high for its extremely narrow exit. It operates similarly like a piston or a steam engine, with the same mechanism. It prevents the cooker from being disturbed once it is under pressure and altering it is only possible once it depressurizes.

The typical first generation pressure cooker only consists of one pressure level while few of the latest models have the provision of modifying the weight of the valve to vary or adjust the temperature.

  •    Second generation

Second generation or latest generation pressure cookers are easily distinguishable as they use spring-loaded valves rather than weight-modified valve of the first generation. The spring valve stays invisible from the outlook of the pressure cooker although they can be set to either increase or decrease the pressure limit. One of the newer versions of the pressure cooker depends on a dial that adjusts the pressure through moving it around. The movement of the dial vents the pressure from the cooker while cooking. 

You can choose multiple pressure options according to your need, as these cookers operate through a feasible mechanism. Another kind of second-generation pressure cookers prevents steam release and instead uses the indicator operation to show how far the pressure has reached. The cooker releases its steam only once it opens or is left for a longer time on the stove due to its tight sealed quality.

  •    Third generation

Third generation pressure cookers come with an electrical source and are known as electric pressure cookers. The electric source is located at the base of the pressure cooker generates pressure, find more information about it along with best pressure cooker reviews. Like other cookers, these too depend on a spring-loaded valve. There are further three generations of electric pressure cookers. The first generation integrates a mechanical timer, while the second has a digital controller and the third one with smart programming.

The heat source generated automatically to maintain the pressure under operation. It carries features that provide dual pressure settings, timer control, and an option to keep the food warm. The enhanced technology helps users to figure what is going inside the pressure cooker through the provision of microchips. These microchips are programmable so you can monitor data inside the cooker while the food is cooking. This helps you to adjust pressure according to your requirement.
