Many families will keep the leftovers in an electric cooker until the next meal or overnight. This is a wrong approach. Using an electric cooker to keep the food warm for a long time will affect the service life of the electric cooker and pose certain safety risks. , It is also easy to cause food poisoning by breeding bacteria in food!
Safety issues of electric pot heat preservation
When using an electric pot to keep food warm, if there is water in the pot, it is generally not dangerous, but if there is no water in the pot, there will be certain safety hazards.
Electric heating pot thermostat
Most electric heating cookers now have automatic protection functions. There are two temperature control devices inside the heat-preserving electric heating pot, namely a safety thermostat. The left and right sides of the electric heating pot are to ensure that the working temperature of the electric heating pot will not exceed the safe temperature, and the power will be automatically cut off if the safe temperature is exceeded. The other is the heat preservation thermostat. Its function is the same as that of the safety thermostat, but the heat preservation thermostat limits the temperature to about 60 degrees. When the temperature is higher than 60 degrees, it will automatically cut off the power and terminate the heating. It will automatically start heating after 60 degrees, so as to realize the constant temperature insulation function.
Electric heating pan
There are these two thermostats inside the electric heating pot. Whether you are burning dry or keeping warm, it will protect the electric heating pot at a safe temperature. But in case the thermostat is damaged and the pot lacks water, the electric heating The pot will keep heating and the temperature will continue to rise until the heating wire of the heating tube burns. At this time, the electric heating pot will be damaged, and there may even be the possibility of igniting the surrounding flammable materials. Therefore, when using the electric heating pot, you must not dry it without water, do not leave it in a long-term heat preservation state, and do not leave it unattended for a long time.
Long-term insulation is easy to breed bacteria
The electric pots on the market now basically have the function of heat preservation, which can keep the food at about 50-60℃. The heat preservation function is practical and convenient, but the temperature below 60℃ is the temperature that is most likely to breed bacteria, so use the electric pot to keep warm. Function: Keep food warm for no more than 2 hours. Too long time will cause the loss of nutrients and the problem of bacterial growth and contamination of the food. When a large number of bacteria are produced but the food has not apparently spoiled, it is difficult to see the appearance and taste of the food Distinguish whether it is contaminated by bacteria, it is easy to eat bad stomach, and even food poisoning.
Tips for Insulation of Electric Pot
When holding food in an electric hot pot, make sure that there is enough water or soup in the pot. Do not keep the dry pot without water. To keep dry ingredients, you can add water to the pot and put it on the steamer. Put the dry food on the steamer to keep it warm. Keep the heat preservation time no more than 2-3 hours. If the heat preservation time is too long, there is a risk of bacteria breeding. There must be someone at home during heat preservation. You cannot use the heat preservation function when there is no one at home to prevent accidents.
