What is the difference between rice cooker, electric stew pot, purple casserole, electric pressure cooker and pressure cooker
1. Rice cooker: It integrates various functions, which can not only save money, but also make effective use of home space. The current rice cooker not only has the function of cooking rice, but also is proficient in cooking porridge and stewing soup, and can also make cakes. There are also some pressure cookers that can cook chicken without water. But most households generally use it for cooking.
2. Electric stew pot: It is a kind of electric pot, but the power consumption is much smaller than that of electric cookers such as rice cookers, which is more suitable for stewing porridge and soup. The electric stew pot adopts the simmering method to stew porridge and soup, which can make the taste and nutrition of the ingredients and seasonings spread into the porridge and soup, and the fragrance is very strong. Because the power is small, there is no need to worry about the long time of stewing.
3. Purple casserole: It is a new generation of health-care pot. Now there are purple clay rice cookers and purple clay stew pots on the market. The purple casserole can remove the metal materials and chemical coatings that are harmful to human health. Purple casserole is used for slow-fire cooking such as boiling, stewing, stewing, boiling, and stewing.
4. Pressure cooker: It is an upgraded product of traditional pressure cooker and rice cooker. It combines the advantages of pressure cooker and rice cooker. Advantages: It adopts new technologies and new structures such as elastic pressure control, dynamic sealing, external screw cap, and displacement-adjustable electric switch, fully sealed cooking and continuously adjustable pressure, which completely solves the safety problem of pressure cookers and relieves consumers of ordinary pressure cookers. Many years of hidden safety hazards; its thermal efficiency is greater than 80%, saving time and electricity (more than 30% electricity saving than ordinary rice cookers). Electric pressure cooker is indeed a relatively practical cooking appliance. It has the incomparable advantages of other cooking utensils, can meet various cooking needs, can quickly, safely and automatically realize a variety of cooking methods, and its energy-saving and nutritious characteristics are the direction pursued by modern people. In terms of function, it integrates the functions of a variety of appliances, and is the first choice for replacing rice cookers, pressure cookers, electric stew pots, stew pots and other pots. Therefore, the future development prospect of electric pressure cooker is very optimistic, the market space is huge, and it is a product worthy of development.
5. Pressure cooker: The pressure cooker, also known as the pressure cooker, can be used to heat the cooked food to more than 100 ℃. It was invented by the French physicist Papin in 1679. It has a unique high temperature and high pressure function, which greatly shortens the cooking time and saves energy; but the pressure cooker with high working pressure also damages nutrients.
The principle of the pressure cooker is simple, because the boiling point of water is affected by the air pressure, the higher the air pressure, the higher the boiling point. In the mountains and plateaus, the pressure is less than 1 atmosphere, and the water can boil at less than 100 ℃, and the eggs are not cooked with ordinary pots. When the air pressure is greater than 1 atmosphere, water will only boil when it is above 100°C. Our commonly used pressure cookers are designed using this principle. The pressure cooker closes the water quite tightly. The water vapor generated by the evaporation of water cannot diffuse into the air and can only remain in the pressure cooker, so that the pressure inside the pressure cooker is higher than 1 atmosphere, and the water temperature is higher than 100 ℃. Only when it boils, a high temperature and high pressure environment is formed inside the pressure cooker, and the rice is easy to cook quickly. Of course, the pressure in the pressure cooker will not be unlimited, or it will become a bomb.
