The second generation of pressure cookers came into production in the early 1900s, relying on a spring-loaded valve to release excess pressure. The first recipe book for the innovation was published in 1924 by

Traditional cooking vessels are non-pressurized like pots, pans and steamers cook at boiling point, which is 100 °C (212 °F), meaning foods to cook at their natural rate. Once the temperature reaches boiling point, excess moisture (water) vaporizes and dissipates the energy into steam.
In a sealed, pressurized vessel, however, The boiling point of water is increased significantly. As temperature rises, so does the amount of pressure within the container, which results in superheated water.
The contained pressure builds, and once it reaches 100 kPa of pressure above the existing atmospheric pressure the heat of the water rises to around 120 °C (248 °F), approximately 20 °C (68°F) higher than water typical boiling point.
The device then limits this pressure via a release valve, either spring-loaded or electronically regulated, which keeps the pressure consistent throughout the cooking process.
By creating this high pressure and creating high than average temperatures while cooking, the food cooks far more quickly, sometimes to as much as 30% or more. The pressure also forces the flavours of the ingredients to fuse more effectively.
Reduces compounds harmful to health
Because the food inside a pressure cooker is bathing in steam, the compressed high-heat helps to eliminate cancer-causing compounds. These include acrylamide as well as heterocyclic amines which arrive when high-heat cooking methods.
It also helps to remove anti-nutrients like lectins and phytic acid that are in grain, legumes and pseudo-grains. Above all, these anti-nutrients bind to minerals. This makes them indigestible, and they create inflammation in the gut.
