How Electric Oven Works
Jan 20, 2022
Electric oven is the use of electricity, we can make roast chicken, roast duck, bake bread, cakes and so on. According to the different needs of baked food, the temperature of the electric oven can generally be adjusted in the range of 50-250℃.
The electric oven is mainly composed of a box, an electric heating element, a thermostat, a timer and a power adjustment switch. The box body is mainly composed of an outer shell, an intermediate layer and an inner liner, which forms a three-layer structure. The front and rear edges of the inner liner form curling edges to cut off the air in the cavity; the outer cavity is filled with insulating expanded perlite products to make the outer shell. The temperature is greatly reduced; at the same time, a spring structure is installed under the door, so that the door is always pressed on the door frame, so that it has better sealing performance.
The heating method of the electric oven can be divided into three types: surface heating and upper and lower simultaneous heating.
The difference
The difference in heating principles between electric ovens and microwave ovens determines the difference in the quality of food cooking. Microwave ovens generate heat by colliding and rubbing and vibrating material molecules with microwaves. Molecules move faster. the higher the temperature. In layman's terms. That is, to heat yourself up. The electric oven is a resistance wire that generates heat under the action of current, one is magnetic energy and the other is thermal energy. It heats food through the principle of heat conduction, which is a traditional way of cooking food. Microwave heating is from the inside to the outside, while the oven is from the outside to the inside, the microwave heating effect is uneven, and the water is easy to lose. The oven can heat the food in a balanced way and better maintain the moisture and original nutrients of the food. simply put. The best function of a microwave oven is that it can heat food quickly; but for bread, cake, pizza, or cooking chicken and meat, it is better to use an oven.
