Then it is very important to use a better insulated lunch box in our daily life. The general insulated lunch box can only keep warm for two or three hours, but a good insulated lunch box can keep warm for up to six hours. How long does the electric lunch box heat the rice?
how long does it take for the electric lunch box to heat meals
The electric lunch box can heat meals for no more than half an hour, depending on the power and performance of the insulated lunch box.
1 prepare the food to be cooked and heat the meal: add a proper amount of water (refer to the above table for details) to the heating plate, put the meal into the sub-lunch box equipped by the original factory, put it into the machine body, and then cover the outer box. Cooking rice: add a proper amount of water to the heating plate with a cup (refer to the above table for details), then pour a proper amount of uncooked rice and water into the sub-lunch box, put the sub-lunch box into the machine body, and finally cover the outer box.
Steaming hard-boiled eggs and soft-boiled eggs: add a proper amount of water to the heating plate with a cup, put it in a steaming rack, put the eggs on the steaming rack, and then cover the outer box.
steamed dumplings, hot milk and other foods: add a proper amount of water to the heating plate with a cup, put the food to be steamed or heated on the multifunctional steaming rack, and then cover the outer box.
2 turn on the power and press the power switch. At this time, the power indicator light is on, indicating that the machine has started to work.
3 after the water in the heating plate is boiled dry, the power-off protection function of the product is automatically started, and the indicator light goes out, indicating that the food has been cooked.
How to choose the insulated lunch box
1. Simple identification method of insulation performance: pour boiling water into the insulated cup, tighten the cork or lid clockwise for 2-3 minutes, and then touch the outer surface of the cup body by hand. If the cup (pot) has obvious warming phenomenon, especially the lower part of the cup body is hot, it means that the product has lost its vacuum degree and cannot achieve good insulation effect, while the lower part of the insulated cup is always cool. Myth: Some people use their ears to determine whether there is a sizzling sound, but they can't hear whether it is vacuum.
2. sealing performance identification method: after the cup (kettle) is filled with water, tighten the bottle stopper or lid clockwise, and put the cup (kettle) flat on the table, so that there is no water leakage; The screw-in and screw-out of the cup (pot) cover and the cup mouth should be flexible without gap. Fill a glass of water and turn it upside down for four or five minutes, or shake it hard a few times to verify whether it leaks.
3, plastic parts identification method: food-grade new plastic features: small smell, bright surface, no burr, long service life and not easy to age. The characteristics of ordinary plastics or recycled plastics are: big smell, dark color, many burrs, easy aging and easy fracture of plastics. This will not only affect the service life, but also affect the drinking water hygiene.
4. Simple capacity identification method: the depth of the inner container is basically the same as the height of the outer shell, and the capacity (with a difference of 16-18mm) is in line with the nominal value. In order to cut corners and make up for the missing weight of materials, some brands in China add sand and cement blocks to the cups (pots). Myth: A heavy cup (pot) is not necessarily good.
5. Simple identification method of stainless steel materials: There are many specifications of stainless steel materials, among which 18/8 means that this stainless steel material contains 18% chromium and 8% nickel. The materials that meet this standard are green products that meet the national food-grade standards, and the products are rust-proof and corrosion-resistant. The color of ordinary stainless steel cup (pot) is pale or dark. If it is soaked in 1% salt water for 24 hours, it will produce rust spots, and some elements contained in it will exceed the standard, which will directly endanger human health.
