How Pressure Cooker Works Principle

Principle of Pressure Cooker

The pressure cooker, a small giant in the kitchen, is famous for its unique sealing design. It cleverly uses the pressure principle in physics to increase the pressure in the pot by limiting the escape of steam, thereby increasing the boiling point of water. Under this high temperature and high pressure environment, the moisture in the ingredients is quickly released, the fiber is softened, and the fat is also accelerated to decompose, which greatly shortens the cooking time of meat, beans and other foods.

Advantages Of Pressure Cookers

One of the most prominent advantages of pressure cookers is their high efficiency. Since food cooks faster under high temperature and pressure, it can complete cooking tasks in a shorter time. For example, stewing meat only takes about thirty minutes using a pressure cooker, which is a huge advantage for commercial kitchens where time is precious. In addition, the efficient heating process makes the food more tender, so food cooked in a pressure cooker often tastes better.

From a nutritional point of view, pressure cookers can maximize the retention of nutrients during the cooking process because less water is lost during the cooking process. Due to the short cooking time, the water-soluble vitamins and minerals in the ingredients will not be lost over time, which is especially important for nutrient-rich ingredients such as vegetables and beans.

Disadvantages of Pressure Cookers

The use of pressure cookers also comes with some potential risks. The high temperature and high pressure environment of the pressure cooker requires users to strictly abide by the operating specifications. If the pressure cooker is not operated properly, it may explode.

Another disadvantage is that it is difficult to clean. Due to the complex structure of the pot body, especially the sealing ring and valve parts, it is easy to accumulate food residues, which requires particularly careful cleaning work.

How To Use A Pressure Cooker Correctly

Check the seal and valve

Check the seal and valve carefully before use to ensure that they are not damaged or blocked, so as not to affect the sealing and steam pressure in the pot.

Add ingredients and water appropriately

Add ingredients and water correctly. The filling volume of the pressure cooker should not exceed two-thirds of the pot body to avoid excessive liquid overflow.

Control the heat

When using a pressure cooker, the control of the heat needs to follow the following steps:

Initial heating: At the beginning, you can adjust the heat to medium-high so that the temperature in the pot rises quickly.

Pressure reached: When you hear the exhaust valve or pressure valve make a sound, it means that the pressure in the pot has reached the preset level.

Fire adjustment: After reaching the required pressure, reduce the fire to medium-low to keep the pressure in the pot stable.

Avoid too high fire: Never use too high fire to prevent the pressure in the pot from being too high or the food from being overcooked.

Release the pressure safely

Never open the lid immediately after cooking. The pressure in the pressure cooker is still very high, and the steam will spray out quickly, posing a risk of scalding. There are two ways to release the pressure in the pot:

Natural release method: Place the pressure cooker in a safe place and wait for a while until the pressure decreases naturally and the pressure indicator indicates that the pressure has been completely released.

Quick release method: Quickly release the steam in the pot by manually operating the exhaust valve. When operating, be careful to avoid steam burns.

Summary

By choosing the right pressure and cooking time, and strictly following safe operating practices, we can maximize the benefits of a pressure cooker and quickly cook delicious and nutritious dishes.
Hopefully, the guidelines in this article will help you use a pressure cooker more confidently and skillfully in the kitchen, and enjoy a healthy and fast cooking experience.
