Daily hot meals, hot milk, microwave ovens are absolutely home-driven. But many people have seen this scary scene: just after the microwave was activated, there was a crack in the fuselage, accompanied by sparks, white smoke, and the immediate end of the electrical fire。
A lot of people think it's a microwave that's broken, but most things are not machine failure
Today we will tell you once and for all why the microwaves sound, what is absolutely impossible, the hottest hot zone of day-to-day life, and no longer need to be scared and safely use the microwaves at home。
First of all, we understand the core principle: the microwave is using high-frequency microwaves to penetrate food, so that high-speed vibration friction of water molecules inside the food produces heat, which is internal and external to heat at the same time。
The sound of cracking is essentially for two reasons: the creation of electric sparks and local high-temperature bursting; and the expansion of closed space water and mini-flammation. All noises, sparks and cracks are caused by human inappropriate placements。
Focus! Don't stuff these things in the microwave. 90% of them miss it
Category i: all metal dishes and dishes with phnom penh. The stainless steel bowl, the iron plate, the aluminum paper, and the porcelain bowls with golden and silver strips are absolutely prohibited from heating. Metals reflect microwaves, are unable to absorb heat, and allow microwaves to accumulate and discharge electricity, generating electric sparks and cracking, not only to burn microwave magnets, but also to ignite fires when they are severe。
Category ii: foods with shells and sealed membranes. Eggs, quail eggs, unspoken chestnuts, food in sealed bags, many of which facilitate direct heating. The internal moisture of the food is turned into water vapour, the outer casings and the seals are locked into pressure, and the pressure accumulates to the limit and explodes internally, which is also the most common cause of cracks in microwaves, with the guts of the insides filled with residues, which are extremely difficult to clean up。
Category iii: poor plastics, one-time packing boxes. Only plastic boxes marked as microwave heating for pp5 are resistant to high temperatures. The general delivery box, the preservation bag, the foam box, which, at high temperatures, mutilates and staggers and releases harmful substances such as formaldehyde, plasticizers and so on, infiltrates the food and chronically consumes a health hazard。
In addition to this, there are two high-frequency life zones, many of which are committed daily。
A lot of people are used to tropics full of grapes and holy fruit, which is also a high-risk operation! The full spherical berries produce a microwave focal effect, which heats up plasma, sparks and blasts, and is highly flammable to internal oil pollution in the microwave. The correct approach is to reheat semi-chip。
There are also people who use microwaves to heat up water, which is a very hidden security hazard. Pure water is prone to overheating in microwaves, and water temperatures above 100°c are not boiling, and the extraction of a shake-off flash can be sudden and intensely boiling, with spray burns and very dangerous。
To teach you three techniques of safe heating, which are used directly in daily cooking: hot foods to remove seals, tearing the protective film open; hard-coated shell foods to pierces; and the preferential use of ceramics, heat-resistant glass dishes to reject metals and unknown plastics。
Indeed, the microwave itself is a safe and efficient household electricity, and most of the failures and dangers are caused by our irregular use. By avoiding taboos and using the right method, they can be used with security and safety。
