Pressure cooker is a dangerous tool in household appliances. Before use, be sure to pay attention to the instructions and understand the functions of each component. To use a pressure cooker:
1. Put the food to be cooked in a pressure cooker and add appropriate amount of water. Food, food and water should not exceed four fifths of the capacity. At the same time, the water or soup should not be less than 400ml.
2. Remove the safety valve or pressure limiting valve and cover it. Make sure the lid is locked. Put the pressure cooker on the fire. Open a big fire. The pressure cooker began to convert water into steam.
3. Wait for the pressure in the pressure cooker to rise. When the pressure reaches the set safety limit, the pressure cooker starts cooking food.
After the cover is covered, it can be heated by high fire. When a small amount of steam is slowly discharged from the exhaust pipe, the pressure limiting valve is buckled on the exhaust pipe, and then the float will rise. After the exhaust pipe hisses, the furnace temperature can be lowered appropriately to keep the exhaust gas until the cooking is finished.
Turn down the fire and let the pressure cooker still boil, but there is no whistle. The time is recommended by the recipe. It is best to cook at the suggested time. If the fire is not turned down, the pressure in the pot will continue to rise, and the pressure limiting valve will be opened (honked) to release steam to prevent the pressure in the pot from being too high. The pressure limiting valve is used to prevent the pressure cooker from breaking. This is not an indicator for calculating cooking time.
4. Cooling and Bleeding
Turn off the fire after the food is cooked in the suggested time. So as to reduce the pressure in the pot. Don't try to open the lid. There will be detailed instructions on how to lower blood pressure in the instructions.
Pressure cooker, also called pressure cooker, pressure cooker, is a kind of kitchen cooker. The pressure cooker exerts pressure on water through the physical phenomenon that the boiling point of liquid will rise under higher air pressure, so that the water can reach a higher temperature without boiling, thus accelerating the efficiency of stewing food. It can be used to heat cooked food to above 100℃. At high altitude, the pressure cooker can avoid the problem that the boiling point of water decreases and it is difficult to cook food.
Pressure cooker, also called pressure cooker. The advantage of using a pressure cooker is not only that the cooking time is short, but also that the cooked food tastes good, especially the meat that is not easy to cook becomes easy to cook and tastes good. However, at the earliest time, the name of the pressure cooker was "Papin Pot", which was invented by a French doctor named Dennis Papin. Papin is a doctor, a physicist and a mechanical engineer. Solid knowledge of physics and mechanical theory is the reliable basis for his invention of pressure cooker.
Deni Papan (1647— 17 12), a Frenchman, was Huygens' assistant. 1675, Papan came to England to work with robert boyle. He was elected to the Royal Society in 1680. An article on "Digester" was published in 168 1. A "digester" is a device that softens bones by boiling water in a sealed container. As we all know, water is boiled under high pressure, and the boiling point is higher, which enhances the solubility of water.
