Because of the limited amounts of fossil fuel, electric appliances like microwave ovens and induction stoves are substituting gas stoves and grills as the primary appliance used for food preparation in many homes. Microwave ovens are obtainable in a variety of dimensions, designs and features with respect to the requirement of buyers and their finances. Simple microwave ovens may be utilized just for warming food while high odd models will blend the features of an oven with a microwave grill.
ovens have a magnetron, a vacuum tube which produces microwave frequency waves
out of the high voltage current. The high voltage is created using a step up
transformer. For the majority of microwave ovens, the frequency of the
microwave radiation created is 2.45 GHz. At this frequency the microwave waves
connect the food and water molecules, heating them so that the foods are cooked
and prepared to be eaten. These microwaves are dangerous to human health, so
proper care should be taken to ensure that the microwave oven is correctly
sealed when it is turned on and used for cooking food. Some microwave ovens
have specialized locking features to restrict misuse by children.
ovens can be classified based on a variety of factors - installation, capacity,
power rating. Depending on the way the microwave ovens are setup, they may be
considered as over the counter microwave ovens or perhaps under the counter
microwave ovens. An under the counter microwave oven is lightweight and can be
setup below the kitchen counter, so that the small space on the counter can be
kept free. Over the counter microwave ovens comprise of two different sections
- a range hood for getting rid of smoke, odours and steam created during
cooking using charcoal filters and a conventional microwave oven. Considering
that free space is required to expel the gases from the range hood, the setting
up requirements for over the counter microwave ovens vary.
the high frequency of microwaves utilized in microwave ovens, the types of
utensils that may be used in a microwave are restricted. Steel and metal
utensils can't be used, ceramic; porcelain or certain types of polymer
containers have to be utilized. Microwaves are also categorized on the basis of
the capacity, the dimensions of microwave oven. The power rating of the
microwave oven is an additional method used to distinguish between the assorted
models of a microwave oven, and low power models are often less expensive.
Combination models may permit the user to bake or grill food, and also being
able to microwave the foods.
models of microwave ovens have just a small number of settings and are mainly
used for heating of food. More costly models of microwave ovens will have a
multitude of features such as provision for variance in temperature, menus for
several types of food, automatic switch off. These models may feature an
electronic display to flash messages, and sound alarms .Many models of microwave
ovens will include a timer which permits the food to be cooked for a
predetermined duration. Microwaves were originally used for heating food and
creating popcorn, but nowadays the models available allow users to cook complex
dishes with pre-set menus for sought after dishes.
modified microwave ovens are used in electronic harassment. The high frequency
waves of these ovens can be utilized to disturb the sleep of a specific
individual or cause extreme headaches, when the ovens are located in the
vicinity of the specific person’s home.
