How Does a Pressure Cooker Pot Work

October 7, 2015 / no comments, on Blog

One of the great features of a pressure cooker pot is that it can be a real time saver in the kitchen. It can also perform the functions of a few different kitchen appliances, which can save you space and money at the same time. Due to the fact that pressure cookers use steam to cook food, they can also create healthier meals than other methods of cooking. Many people have come to embrace pressure cookers as an economical and convenient way of meal preparation, yet at the same time wonder how they actually function. The following is a manual for using a pressure cooker pot, including an explanation of how they function to cook food more rapidly than other strategies.

A pressure cooker pot, at first glance, resemble any regular kitchen pot. The main contrast you’ll notice is the notches in the edge of the pot, which regular kitchen pots don’t have. These sections are matched to corresponding markings on the pressure lid.

Once the item being cooked and prescribed amount of liquid are in the pressure cooker pot, the lid is placed on the pot and bolted into place, forming an airtight seal through which no liquid or steam can escape.

Pressure cookers work pretty much as their name suggests. As the liquid inside the pot begins to heat up, it starts to boil and steam is created. In a typical non-pressurized pot, even with a lid, quite a bit of this steam will escape around the edges. Because the steam inside a pressure cooker pot cannot escape, pressure develops inside the pot. This causes food to cook faster and all the more equally in two ways.

Boiling water (and the steam it delivers) has a temperature of 212 degrees Fahrenheit. Under pressure, steam reaches much higher temperatures. Secondly, the pressure inside actually drives the steam into the food, facilitating effective and uniformly distributed heat transfer.

Pressure inside a pot has its own unit of measure called PSI, or pounds per square inch. Most formulas for them call for relatively high pressure (typically of around 15 PSI) which heats the inside of the pot to a temperature of approximately 250 degrees Fahrenheit; an increase of about 40 degrees above foods boiled or steamed in a typical kitchen pot.

Some people have shown concerns about the safety of pressure cookers, yet nowadays pressure cookers are constructed from highly-resistant materials, making them quite easy to operate after all safety precautions have been taken. Proper sealing of the pot and right use of the vent valve located in the focal point of the lid will guarantee that anybody using a pressure pot does it safely, while cooking flavorful, healthy foods rapidly and conveniently.
