(1) Don't get your hopes up. When the pressure in the pot is generated, there is almost no safe buffer space. Continue to heat, the pressure will increase, causing an explosion. According to the manufacturer's instructions, the food in the pot should not exceed 2/3 of the total volume, preferably 1/2.
(2) Before each capping, carefully check whether the vent hole in the center of the cover is unblocked. If the light is not bright and the air blowing is not smooth, it must be blocked and removed before it can be stamped.
(3) After capping, the scientific method is not to add the pressure limiting valve first, and then add the pressure limiting valve in time after the cold air in the pot is heated and discharged (subject to the uniform steaming of the central hole).
(4) Before adding the pressure limiting valve, check the air holes on the pressure limiting valve. Methods You can blow air through the big hole with your mouth, and air will come out when the shunt hole and drainage hole are clear. If it is blocked, you can use it by poking it with a thin wire.
(5) Don't cook beans, porridge and ribs seaweed soup in a pressure cooker. The foam produced by high pressure in the pot is enough to block the central hole and air hole of the pressure limiting valve, which is very dangerous.
(6) Start cooking with high fire, and switch to low fire after charging.
(7) When using fire as a heat source, be careful not to overheat the handle of the pressure cooker. Children and people who can't take care of themselves can't use pressure cookers.
(8) Items with strong corrosiveness such as acid/alkali/salt cannot be placed or cooked. The use of electric pressure cookers is similar.
(9) After using the pressure cooker, it should be thoroughly cleaned and dried, especially the pot ring should not be soaked in grease for a long time, and the pot cover should be covered on the pot body.
Extended data
Because the function of electric pressure cooker is obviously different from other cookers, it is very suitable for modern people's living habits-fast, convenient and multifunctional, and has great market potential. After a round of market reshuffle, by the end of 20 10, there are about 150 brands of electric pressure cookers in the domestic market, which is a practical cooking appliance.
It has incomparable advantages over other cookers and can meet various cooking needs. Functionally, it integrates the functions of various utensils and is the first choice to replace rice cookers, pressure cookers, electric stews and stews. Therefore, the future development prospect of electric pressure cooker is very optimistic, and the market space is huge, so it is a product worth developing.
1, the purchase of electric pressure cooker can be decided according to personal preference. Mechanical electric pressure cooker and microcomputer electric pressure cooker have different control methods, but the use effect is exactly the same. The former is complicated to operate, while the latter is convenient and intuitive, but the price is higher.
2. The size of the electric pressure cooker should consider the crowd. Families with 2-3 people choose 4 liters, families with 3-5 people choose 5 liters, and families with more than 6 people choose 6 liters or 8 liters.
3. In terms of performance, it is important to check whether the contact between the inner pot and the electric heating plate is good, whether the power supply and heating are normal, and whether the function switch and the touch button are normal. The rotary regulator and timer should move freely, the heating and heat preservation indicator lights should be turned on and off accordingly, and the timer can be automatically turned off after the countdown is completed. The power cord and plug should be well insulated and free from oxidation and corrosion.
4. The performance of the safety device of electric pressure cooker is very important, because the safety performance directly affects its performance. First, check that the sealing ring of the pot cover should be free from deformation and cracking. Insert the pot cover into the mouth of the pot body and rotate the handle of the pot cover clockwise to the positioning position to make the pot cover seal well.
Check that the installation of float valve, exhaust valve, safety valve and anti-blocking cover should be firm and reliable, and the external surface of metal should be bright without oxidation and corrosion. Finally, water is injected to electrify the pot, which is heated to a predetermined temperature, and the exhaust valve exhausts normally, and the timer automatically closes.
5. Whether the instructions, relevant signs and safety tips are complete represents the sense of responsibility of the enterprise and can ensure the correct and safe use of consumers. Therefore, this inspection cannot be ignored.
6. Products with 3C certification should be purchased. The certified electric pressure cooker has guaranteed quality, qualified electrical performance and in-place after-sales service.
