1, first soak the whole pot in water for three hours. Then the pressure cooker with washing Jin (can use detergent) wash. The rubber ring of the pressure cooker all touch with oil once! (New to prevent abrasion when the first time to close the lid). Check that the air holes are tightly fitted. Can be used. Pressure cooker is also called pressure cooker, pressure cooker, is a kind of kitchen cookware. Pressure cooker applies pressure to water through the physical phenomenon that the boiling point of a liquid will be raised under higher air pressure, so that the water can reach a higher temperature without boiling, in order to speed up the efficiency of stewing food. It can be used to heat the food to be cooked to more than 100°C. In high altitude areas, the use of pressure cookers can avoid the problem of water boiling point lowering which makes it difficult to cook the food. The advantages are time-saving and energy-saving, the disadvantages are incorrect operation or defective, there is a possibility of explosion and cause injuries in the use of newly purchased pressure cooker, you need to add a small amount of food oil along the edge of the side of the cooker above and below, because the sealing ring of the new pressure cooker are more elastic, and this will facilitate the opening and closing for the first time. And the lid, body and handle should be cleaned before each use to make it easier to close the lid.

2, put food need to pay attention. When putting food, do not let the food and water more than four-fifths of the capacity of the pot, legumes do not exceed two-thirds of the capacity of the pot, to avoid the expansion of the gas produced by the food through the steaming of the vent hole blocked. But accordingly the food in the pot should not be too little, water or soup should not be less than 300 ml (about two bowls).
