微波炉和电烤炉都可以加热食品,于是好多同学都认为它们是一样的.其实两者的加热形式有很大的区别,正是因为如此,才有了加热时间的不一样和加热结果的不一样.电烤炉的加热:电烤炉通电后,电热丝的温度升高,可升至大约1000℃,然后通过辐射的方式把热量传到食品处,食品的表面先受热升高温度,和食品内部形成温度差,使热量沿着.食品由表及里传递,最终使食品整体被加热.这种加热方式被称为表面加热,加热时间较长. Microwave ovens and electric ovens can heat foods, so many students think that they are the same. In fact, there is a big difference between the two forms of heating, it is because of this, there is not the same heating time and heating results are not The same as the heating of the electric oven: After the electric oven is powered on, the temperature of the electric heating wire rises to about 1000° C., and then the heat is transmitted to the food by way of radiation, and the surface of the food is heated to an elevated temperature first, and The temperature difference formed inside the food causes the heat to move along. The food is transferred from the surface to the inside of the food and eventually the whole food is heated. This heating method is called surface heating and the heating time is longer.
