Microwave ovens transfer heat to food through the air in the oven, which is from the inside out. The electric oven converts electric energy into heat energy through resistance wires, and this process is from outside to inside. Because their heating principles are completely different, the smell and taste of baked food are also different.

For example, when baking a cake, the microwave oven is not as easy to adjust the temperature as the oven, nor does it have the function of baking up and down, and the baked cake is not very soft, dry and without moisture.

Moreover, most of the molds used in the oven are metal products, but the metal products can not enter the microwave oven, which will interfere with electromagnetic wave heating, resulting in uneven heating of baked goods and the danger of electric spark explosion. The oven does not have this concern, such as iron-aluminum baking tray, ceramic baking tray and metal baking net. Can be used.

Matters needing attention in purchasing microwave oven

1, carefully check the surface of the box when choosing a microwave oven. Generally, the plastic parts of microwave ovens are smooth and bright, indicating that the product quality is good, the surface color should be uniform, and there are no fading, cracks and scratches.

2. Microwave oven is a product with long duration of high temperature. You can pinch every part of the door with your fingers to see if it is hard. In addition, it is necessary to open the oven door for observation. A good microwave oven is hard and can't be pressed.

When choosing a microwave oven, we should not only look at the power level, but also look at the output power, because the output power is useful for heating food. The input power of microwave oven is usually marked on the back of the machine. The smaller the difference between input power and output power, the better. The smaller the difference, the greater the effective power of the microwave oven.
