Stainless steel Energy-saving cooker set The stainless steel energy-saving pot is made of high-class stainless steel with fine processing, provided with dual effects of energy saving and heat preservation. It is well known for its safety use, and time & gas saving feature. This pot consists of six parts, Silicon heat-retaining outer pot, alloy heat-gathering steel rim inner pot, two-layer bowl-shape radiation lid, strengthened glass inner lid, four stainless steel cups (For steaming), and stainless steel grid (For steaming). There is a heat-gathering steel rim under the inner pot for gathering and preserving heat. The heat-gathering steel rim absorbs the remaining heat from burning when you are cooking. Once the cooking achieves the boiling state, you can move the pot inside the heat-retaining outer pot. For the heat-gathering steel rim will give out heat, the pot inside will retain boiling for 25 minutes until the food is cooked thoroughly, when the pot enters the heat preservation state. With this energy-saving pot, you just need to cook the food to the boiling state, which usually takes only 10 minutes. It is very energy saving (Save 25%-30% energy than autoclave, and 50% energy than the ordinary pot), and the holding time in ambient temperature can reach 10 hours. This pot is cooked under the normal pressure, which is safer than the autoclave. Besides, it keeps the original flavor of food without getting burned or destroying the nutrition of food. The pot is heated mainly by burning gas
