Why consider a Combination Microwave?

Most of us know the advantages of Microwaves - i.e.: healthier cooking (nutrients retained); speed, economy; less smells and washing up.

But, only recently, are we realising the benefits of Combination Microwave Ovens. They combine traditional and microwave ovens. At the same place and at the same time - either separately or together. A lot of combination ovens can also grill food, use fan assistance in the oven, or use automatic controls to ensure that the right cooking methods, power and timings are used. And they have come down in price a lot over the last year or two as they have become more popular.

Combination Microwave Ovens - Some Benefits

So you are looking for a new microwave oven and you are fast beginning to realise that there is a very large amount of choice about the types of microwaves and features available to you. Most people automatically plump for a standard microwave oven as they see this as sufficient to re-heat microwave meals and cook the occasional bowl of porridge. You should however take a moment to consider the possibility of instead purchasing a combination microwave oven. There are a number of benefits to these over standard microwaves which could mean that it would be worthwhile you making the investment.

Microwave + Oven = Combination Microwave Oven + More Space

The main benefit to having a combination microwave over a standard microwave is that by combining your microwave and your convection oven in one device you are eliminating the need for having both. Traditional ovens are most often the largest single item you have in your kitchen, so by removing the need for an oven you are probably going to gain a lot of space. This could be handy if for example you were considering getting a dishwasher but had nowhere to put it. Alternatively, you may live in an apartment where there just is no space for an oven, but you may be able to find counter-top space for a combination microwave oven. You may think that a microwave oven could never be a substitute for a proper convection oven, but many of the higher-end models even offer an in-built grilling function.

Bigger Capacity for Cooking

Even if you don’t have a space issue and you are really attached to your oven there are other reasons that you may still consider purchasing a combination microwave oven. Another key reason why it may be better for you is if you have a large family or regularly cook for a substantial number of people then it may offer an increased capacity. If you cook a proper Sunday roast every week there is every chance that by the time you have put the joint in the oven you don’t have room to put anything else in there like a tray of potatoes. If you had a microwave which had the ability to cook these items like a normal oven then you wouldn’t have to sacrifice them due to a lack of room.

Time Saving Devices

Another benefit which many people may not be aware of is that a combination microwave oven can actually function as a great time-saving device. Many models actually let you choose to microwave heat food and use traditional convection heating at the same time. As the food is being heated in two different ways this actually lets the food cook quicker but without burning. So if you are one of these people who finds that large amounts of your evening are eaten up in waiting for things to cook, a combination microwave oven could be the answer to your prayers.

The Decision is Yours

At the end of the day, combination microwave ovens usually cost more than a standard microwave and so they are not for everyone. If you recognise any of the problems that I have discussed here though then it is quite likely that you would benefit by investing that little bit more in a combination microwave oven rather than a standard model.

How Microwave Ovens Work

A magnetron vacuum tube is the engine behind the way a microwave oven works. Electrical energy is converted into microwaves, a high frequency type of electromagnetic wave. The microwaves then enter the microwave oven through a wave guide and stirred by a fan to be distributed evenly.
There are three possible results for these waves. they are either reflected back in, pass through materials, or absorbed by other materials. These types are reflected back back by a metal. This is why non metallic utensils should always be used in a microwave. Paper, pottery, glass, china, and several makes plastics allow them to go through. They consequently make ideal cooking utensils. The fat, water, and other substances in the food absorb them, causing the food molecules to vibrate very quicklymillions of times each second, actually. This is called dielectric heating. Many molecules (including water) have a negative charge at one end and positive one at the other. These types because of that circulate very rapidly as they try to get in line with the alternating field of the microwaves. This process is more {efficient} on water than on other food materials, and also works quickly on frozen water. The heat produced thus cooks the food. This is similar to rubbing pieces of wood together to make a flame. It is often thought that microwave ovens cook from the inside out. This isn’t the case.
Then, depending on the amount of water, microwaves fast enter a distance into the food. However conventional cooking will only have a short term effect on the surface area of food.
This way is entirely different to conventional cooking, where energy is passed along a number of molecules until the food is totally hot and thus becomes cooked. Microwave containers remain less hot and timings are significantly reduced.
A variation is the convection or combination microwave. These types are ideal for cooking prepared dishes, especially if browning is desirable. Some recent ones have a powerful halogen bulb which helps fast browning. It is also possible that an accessory browning tray is used made of porcelain or glass. This enables the outer layer of food to become oxidised until it turns brown.
Microwave models have generally the same design. Microwaves have a cabinet, a magnetron vacuum tube, a wave guide, wave stirrer, controls, and power supply and cord. Some also have extra features such as automatic defrost, variable power, a turntable, a built in thermometer, or a browning feature.
There is metallining inside the walls and base, which stops the microwaves from getting out , and reflects them back in to ensure the food is thorougghly cooked. The frame have specially formulated seals that is designed to ensure that the microwaves stay in. Also there will be a safety device that ensures that the microwaves will cease whenever the door is not closed. The door itself usually has a glass panel for good visibility, with a layer of conductive mesh to keep a barrier. The hole diameters in the mesh is less than the wave length of the microwaves, so the radiation can’t get past the door. Whereas light (with a much shorter wave length, can get through.
Several makes types allowseveral levels of power to be applied, usually with a power level that defrosts. In most cases this doesn’t mean that the amplitude of the microwaves varies - just that they are powered off and on at particular regular periods.
