The Mechanic of Microwaves: The Basics

Nearly since 1940s, microwaves became an important part of the households. Today, 2016 household meals are not complete without a little help from the microwave. Well known as a multi-purpose device, microwaves ease almost everything that people do on a stove or a standard oven, and for this reason industry has had come with a several kinds of microwaves suitable to the needs of the users in a reasonable price.

Having a microwave reduces the need of having different appliances to perform different functions.  A microwave has become such an important part of every household because it can perform the following functions effectively.

How do Microwaves work?

Microwaves use high frequency electromagnetic waves which cause molecules of liquid present in the food to vibrate and create friction which produces the heat and cooks food. Microwaves used for cooking are electromagnetic waves possessing frequencies around the 2.45 GHz range. When it comes to microwave ovens, once the fields are alternating, the rotation will change from clockwise to counterclockwise at regular time intervals. During this procedure water molecules agitated own heat energy that can rub off, like friction method, -as we mention before- to nearby molecules, which means that if the water molecules are well distributed in the body subjected to the microwave like in the case of food, the entire body can heat up quickly and uniformly.

Microwaves heat and cook your food from the inside out rather than the other way which happens with cooking the food on a stove, which takes long time. These are the reasons why they have become so popular.

Nowadays, using a microwave to cook a meal saves you not only too much fuel but also a lot of time. Within minutes you can steam your rice and even cooking noodles. For this and other reasons, microwaves have become very famous in not only in bakeries but also in households.

Parts of a microwave

FinishBuild, would like to take time on learning with you about this device. In the following you would get a more detailed description of this magnificent device:

Door. Microwave ovens generally look like a portable small oven. Usually assembled with a parallel door, the inside where the food is placed to be heated is called the cavity and is generally made of steel as microwaves can’t go through steel.

Buttons. There is a control panel and a display section frequently located at the right side of the door. Behind the control panel, there is a circuit board which controls the operations and the functions of the Microwave oven.

Magnetron. This is the real heart of the Microwave Oven is the Magnetron which is the microwave generating device. Inside the interior space is a fan, which pulls air through vents in the side and across the electronics board when the oven is on. The air is blown out of the fan and through the cooling fins of the magnetron. This is to cool the device during operations.

Plate. Inside the cavity, a turn table is draw together, which rotates automatically with motor assistance turning clockwise and anti-clock wise when cooking food. This ensures that the food is cooked uniformly from all sides. On the other hand, in Grill and Convection Microwave Ovens, metal racks or trays are provided to place the food items closer to the grill placed at the top. This results in top and entire browning.
