1. Wait to flush out the heat and then add the pressure limiting valve. Turn off the flame immediately when there is a ringing sound. When the pressure disappears, you can open the pot to eat. This saves fire and doesn't stick to the bottom of the pan. If the fire is used properly, even the potpourri is not. But must pay attention to: (1) according to the nature of the rice, water should be added to the appropriate, rice on the soft and hard appropriate; (2) after the fire is out of the pot pressure to retain, do not rush to gas or forced cooling. Therefore, it is best to cook rice first, then stir fry.

2. After the rice is ready, immediately sit the pressure cooker in a pre-prepared pot of cool water. Just tip it out after two or three seconds.

3. After the rice is steamed, if you let the steam out slowly and naturally, then remove the pressure valve and open the lid, the rice will not stick to the pan. If you need to eat urgently, just after the first meal, then put the lid of the steamer to cover tightly, without the restriction valve, and then open the lid of the steamer when the second meal is served. The rice sticking to the bottom of the pot will be easy to shovel off.
