1. The steps for cooking soybeans in a pressure cooker are as follows:

(1) The amount of soybeans to be cooked should not be too much. Generally, 2/3 of the capacity of the pot is appropriate, and the amount of water and soybeans is The ratio is 1:3.

(2) Wash the soybeans, put them into the pot and add water. Before closing the pot lid, be sure to check whether the hole of the pressure limiting valve in the center of the pot lid is unobstructed. Are other valves normal?

(3) You can use medium or high heat to cook at the beginning. After the water in the pot boils and the pressure limiting valve of the pressure cooker makes a "chi----" sound, you should turn off the heat immediately. It is appropriate to make the pressure-limiting valve of the pressure cooker make an intermittent "chi---chi---" sound. Use this low fire state to continue cooking for 5 to 7 minutes.

(4) After the soybeans are cooked, turn off the heat. You can use a basin with water in it. Carefully put the pot into the cold water in the basin to cool down. You can also use a small amount of water. Let the pot cover cool down. When the pressure cooker makes the sound of sucking air into the pot when watering, you can stop watering, remove the bonnet of the pressure limiting valve, and open the pot lid.

2. Cook the soybeans in the pressure cooker. It will take seven or eight minutes if they are cooked, and 10-12 minutes if they are cooked thoroughly.

3. Safety precautions when using the pressure cooker:

(1) Do not overload the container. When pressure builds up in the pot, there is almost no safe buffer space. As the heating continues, the pressure increases, causing an explosion. According to the manufacturer's instructions, the food in the pot should not exceed 2/3 of the total volume, preferably no more than 1/2. ?

(2) Before adding a lid each time, carefully check whether the vent hole in the center of the pot lid is unobstructed. If you can't see the light and the air blowing is not smooth, it must be blocked. The blockage must be removed before the lid can be added. ?

(3) After adding the lid, the more scientific method is to not add the pressure limiting valve first, and then add the upper limit in time after the cold air in the pot is heated and discharged (based on the uniform emission of hot air from the center hole) pressure valve. ?

(4) Before adding the pressure limiting valve, also check the vent hole on the pressure limiting valve. To do this, you can blow air into the large hole with your mouth. If the diversion and air holes are unobstructed, air will come out. If it is clogged, use thin wire to poke it through before use. ?

(5) Do not use a pressure cooker to cook beans, porridge, ribs and kelp soup. The foam generated by the high pressure in the pot is enough to block the center hole and the vent hole of the pressure limiting valve, causing danger. ?

(6) Use high heat to start cooking, and switch to low heat when the food is out of breath. ?

(7) When using fire as the heat source, be careful not to overheat the handle of the pressure cooker. Children and people who cannot take care of themselves cannot use the pressure cooker. ?

(8) Do not hold or cook highly corrosive items such as acid/alkali/salt. The use of electric pressure cookers is also similar. ?

(9) After using the pressure cooker, wash and dry it thoroughly and thoroughly. In particular, do not soak the pot ring in grease for a long time and place the lid upside down on the pot body.

(10) The general service life of a pressure cooker is 8 years. It must not be "extended service". It cannot be used after 8 years regardless of whether it is damaged or not.
