Difference

1, microwave heating food is inside and outside at the same time, the time is relatively short, light wave is from the outside to the inside of the heating, like you put the steamed bread in the sun, slowly baked, long time, no microwave practical.

2, light wave oven, also known as light wave microwave oven, and the biggest difference between the microwave oven, lies in its heating method. Ordinary microwave ovens, the internal grill tube commonly used copper or quartz tube. Copper tube is difficult to cool after heating, which can easily lead to burns; while the thermal efficiency of quartz tube is not too high.

The grill tube of the light wave oven is replaced by a halogen tube (i.e., light wave tube) from a quartz tube or a copper tube, which can produce high temperature and high heat quickly, and cool down quickly, so that the heating efficiency is higher, and will not be burnt, thus ensuring the color of the food. In terms of cost, the cost of light-wave tube is only a few dollars more than copper or quartz tube, so the use of light-wave tube in microwave oven technology is now very common.

Substantiation: light wave is an auxiliary function of the microwave oven, and only works on the grill. There is no microwave, light wave oven is only equivalent to ordinary oven. Light wave furnace on the market are light wave, microwave combination furnace, in use both microwave operation, and available light wave operation alone, but also light wave microwave combination operation. In other words, the light wave oven is compatible with the function of the microwave oven.

Use

Microwave can be used for heating, defrosting and steaming food; light wave is mainly used for grilling and sterilization.

Extended Information

Microwave is a type of electromagnetic wave. A microwave oven consists of a power supply, a magnetron, a control circuit and a cooking chamber. The power supply provides about 4,000 volts of high voltage to the magnetron, which is excited by the power supply and continuously generates microwaves, which are then coupled into the cooking cavity through a waveguide system. In the cooking cavity near the inlet, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, rotating up after the microwave has a reflection in all directions, so the microwave energy can be evenly distributed in the cooking cavity, so as to heat the food. The power range of a microwave oven is generally 500 to 1,000 watts.

Microwave oven is the use of food in the microwave field to absorb microwave energy and make their own heating of cooking appliances. In the microwave oven microwave generator generated microwave in the microwave oven cavity to establish a microwave electric field, and take certain measures to make this microwave electric field in the oven cavity as evenly distributed, the food into the microwave electric field, by the control center to control the cooking time and the intensity of the microwave electric field, to carry out a variety of cooking processes.

In layman's terms, microwave is a high-frequency electromagnetic wave, which itself does not produce heat, there are microwaves everywhere in the universe, nature, but the existence of nature's microwave, because of the dispersion of non-concentration, so it can not heat the food.

The microwave oven is the use of its internal magnetron, the electrical energy into microwaves to 2450MHz oscillation frequency penetrate the food, when the microwave is absorbed by the food, food within the polar molecules (such as water, fat, protein, sugar, etc.) that is, attracted to the rate of 2.4 billion 50 million times per second of rapid vibration, the macro-performance of this vibration is the food is heated.

The principle of microwave heating is simple: when the microwave radiation to food, food always contains a certain amount of water, and water is composed of polar molecules (molecules of the positive and negative charge centers, even in the absence of the external electric field is not overlap), the orientation of such polar molecules will be with the change of the microwave field.

Due to this movement of the polar molecules of water in food. As well as the interaction between neighboring molecules, a friction-like phenomenon occurs, causing the temperature of the water to rise, and therefore, the temperature of the food. Food heated with microwaves heats up quickly because its interior is also heated at the same time, so that the whole object is heated uniformly and heats up quickly. It heats the food 5cm deep at a frequency of 2.45 billion times per second, accelerating the molecules.

Two effects

1, wave heat effect. Microwave oven cavity of the electromagnetic field changes as fast as 2.45 billion times per second (microwave frequency of 2450MHz), the role of water molecules in the food molecules and other polar molecules, so that the swing back and forth 2.45 billion times / second, due to the high speed of the water molecules between the wheel pendulum friction movement and generate high heat, so as to achieve the purpose of heating.

2, biological effect. Due to the microbial cytosol absorption of microwaves is better than the surrounding other media, so the cells in the microwave electromagnetic field will quickly rupture and lead to the death of the bacterial cells.
