Introduction

Technology today has made life easier and better. As we look at the technologies, what is modern technology? Modern technology is machinery that makes life easier. For example, microwave ovens cook food easily without using any stoves and making a big mess. And dishwashers put all dirty dishes into the dishwasher and it washes them automatically. Modern technology makes things very easy to use and save time comparing it in the old fashion way. Often a country's level of modernization is measured by the ease with which people can communicate with each other. In this report we will be discussing about microwave oven and its usability factors.

Discussion

As the food industry began to recognize the potential and versatility of the microwave oven, its usefulness was put to new tests. Industries began using microwaves to dry potato chips and roast coffee beans and peanuts. Meats could be defrosted, precooked and tempered. Even the shucking of oysters was made easier by microwaves.

Microwave ovens are generally used for time efficiency in both industrial applications such as restaurants and at home, rather than for cooking quality, although some modern recipes using microwave ovens rival recipes using traditional ovens and stoves. Professional chefs generally find microwave ovens to be of limited usefulness because browning, caramelization, and other flavour-enhancing reactions cannot occur due to the temperature range.

On the other hand, people who want fast cooking times can use microwave ovens to prepare food or to reheat stored food (including commercially available pre-cooked frozen dishes) in only a few minutes. Microwave Ovens can also be used to defrost items that will later be cooked by traditional methods, cutting the time it takes to defrost foods naturally. Microwave ovens are also useful for the ease in which they can perform some traditionally cumbersome kitchen tasks, such as softening butter or melting chocolate. Popcorn is one example of a very popular item with microwave oven users.

A microwave oven converts only part of its electrical input into microwave energy. A typical consumer microwave oven consumes 1100 W of electricity in producing 700 W of microwave power, an efficiency of 64%. The other 400 W are dissipated as heat, mostly in the magnetron tube. Additional power is used to operate the lamps, AC power transformer, magnetron cooling fan, food turntable motor and the control circuits. This waste heat, along with heat from the food, is exhausted as warm air through cooling vents.

Display And Control Components Of The Microwave

If new technology is reflected anywhere, it is in the control circuitry of the sophisticated microwave ovens designed for home use. It seems, paradoxically, that as technology advances, the field-availability of the corresponding technical data declines. Indeed, the service literature testing procedures for many control units amount to nothing more than programming instructions, although the value of these should not be minimized, because not knowing how to operate the oven you are about to repair can be quite perplexing to the anxious onlooker who owns the ...
