Advantages of Microwave Oven Heating
____________________________________________________
As the conventional heating methods apply heat to the exterior of a substance; dielectric
substances such as foods, wood, plastics, and rubber are heated unevenly because they
are poor in heat transfer and slow in heat penetration, resulting in a considerable
differential temperature between the exterior and the interior. Accordingly, the heating
temperature needs to be increased gradually in a long time if uniform heating is required.
Also, much heat is wasted for other substances than the heating object, for example, air,
pots, pans and the heat source. Thus the conventional heating is poor in the heat
efficiency and also difficult in the adjustment of the heating rate. On the contrary,
microwave oven heating has the following advantages.
1. Even Heating: Since the microwave penetrates into substances to some depth,
it heats the substances more evenly than the conventional heating methods.
2. Very high heating efficiency and speedy cooking.
3. The microwaves do not heat anything other than absorbing materials such as
food.
4. Exact Control of Heating Rate: The microwave output is regulated as desired
and the cooking time can be instantaneously set by a timer.
5. Heating Substance of any Shape: The microwave can easily penetrate and
scatter into the heating substance of any shape.
6. Simple oven construction and easy handling. The controls are very few and
they are solid state.
7. Very clean heating system, suitable for foods and pharmacy.
Absorption
Those materials which absorb
microwaves, are heated. Foods
rank high as microwave
absorbers.
