The Technology Behind Microwave Ovens

These days, it’s impossible to imagine how your life would be without the presence of the microwave oven in the kitchen. This appliance has gained a massive popularity due to the fact that it helps heat, defrost, and cook a variety of foods in a short amount of time, thus being crucial for the modern people that can’t afford to lose a second when they’re at home. But how do these kitchen appliances work? If you are wondering what technology stands behind your favorite kitchen appliance, the microwave oven, check out the rest of this article to learn everything you need to know about it.

The invention of the microwave oven

The invention of the microwave oven is an accidental one, occurring when Percy Spencer was carrying out experiments with a magnetron. What lead to the invention of this popular appliance is the fact that the inventor had a chocolate bar in his pocket one day when he was working with a magnetron. The chocolate bar quickly melted when the magnetron generated heat, this being the moment when he got the ingenious idea to use the magnetron for cooking food. After a couple of tests and trials, he developed a microwave oven that could be used to cook all types of foods, this being the first unit to appear and the one that we have to thank for the variety of models that we have on the market at the moment.

How microwave ovens cook food

All microwave ovens have a common element inside of them, this element being the magnetron. When you set the unit to start cooking, the magnetron takes electricity from the power outlet, transforming it into high-powered radio waves. These waves are then blasted into the food compartment through a waveguide while the food is sitting on the turntable that slowly spins in order for it to be cooked evenly. What makes this system so efficient is the fact that the microwaves bounce back and forth off the reflective walls of the compartment, penetrating the food to perfectly prepare it. When the waves pass through the food, their molecules vibrate quick and they produce heat, this being the explanation to why these appliances are so quick when it comes to defrosting, heating, and cooking the food.

Safety issues regarding the quality of the food

There are people these days who worry that if they microwave the food they plan to eat it will lose its nutrients and vitamins due to exposure to radiation. There is no reason for you to worry about this aspect because the food is subjected to a far too small amount of radiation over a very short period of time, so there will be no deterioration occurring. Also, you won’t be radiated yourself if you consume it, this being another common myth regarding the popular kitchen appliance.
