In modern kitchens, pressure cookers have become a must-have kitchenware for many families with their high cooking efficiency, energy saving and time-saving characteristics. However, when using a pressure cooker for steaming, a common question is: will steaming in a pressure cooker with a plate lead to **? It's not just about kitchen safety, it's also about the right way to use a pressure cooker. This article will examine this topic through scientific analysis and give clear answers and suggestions.
First, we have to understand how a pressure cooker works. The pressure cooker increases the pressure and boiling point of the pot by sealing the space inside the pot so that the steam generated by the evaporation of water at high temperatures cannot escape, so that the food can be cooked thoroughly in less time. When it comes to putting items such as plates, the key is whether those items can withstand the high temperatures and pressures in a pressure cooker.
Let's look at this from a physical point of view. The internal temperature of the pressure cooker can reach more than 100 meters under normal working conditions, and the pressure can be as high as 15 atm. If the plates are made of heat-resistant materials, such as ceramic or heat-resistant glass, they are usually designed to withstand such temperatures and pressures. However, if the plate is made of materials that are not resistant to high temperatures, such as ordinary plastic or low-quality glass, there is a high risk that the material will deform or even break when steaming in a pressure cooker because the material cannot withstand the high temperatures, posing a potential safety risk.
Also, consider whether the size and shape of the plate will fit in a pressure cooker. If the plate is too large or irregularly shaped, it can affect the sealing performance of the pressure cooker and cause steam leakage, which not only reduces the efficiency of the pressure cooker, but can also be dangerous.
Next, let's take a closer look at the experimental data. Let's say we take a ceramic plate that is resistant to high temperatures and cook it in a pressure cooker. During the experiment, we found that as long as the plate is placed properly, does not affect the closure and sealing of the pressure cooker, and the plate itself is not damaged, it can withstand the pressure cooker process intact. Conversely, if there are microscopic cracks in the plate or if the material is not resistant to high pressure, even a short steam session may cause the plate to break.
Historically, it has not been uncommon for pressure cooker steaming to cause plates to break. In these cases, accidents often occur due to neglect of material selection or misuse of utensils that are not suitable for high-temperature and high-pressure environments. Therefore, we can conclude that it is safe to use suitable heat-resistant plates when steaming in a pressure cooker; But if you choose the wrong material or size, there is a safety hazard.
Finally, in order to ensure the safety of using a pressure cooker, we make the following recommendations:
Read the instruction manual of the pressure cooker carefully to understand its correct use and precautions.
Choose dishes that are resistant to high temperatures and pressures, preferably kitchenware designed specifically for pressure cookers.
Make sure the plates are free of damage and cracks, and avoid using flawed utensils.
Make sure the plate is the right size and won't affect the tightness of the pressure cooker.
Regularly inspect the pressure cooker's seals and other parts to make sure they are in good condition.
In summary, steaming in a pressure cooker on a plate will not fry, provided that the appropriate material, size and intact utensils are chosen. Only in this way can we enjoy the convenience of a pressure cooker while keeping the kitchen safe.
