微波作为能源技术加以研究与应用,还是近二十年来的事,所谓微波是指介于超短波与红外线之间的电磁波。一般频率在30～300千兆赫,波长在一毫米到一米范围的电磁波称为微波。现代微波能源器具是采用磁控管来产生微波能,它的加热特点是通过微波能辐射的作用,使被加热物的分子间产生每24亿万次以上的惊人速度运动,从而使分子彼此之间强烈碰撞与快速摩擦产生大量热能。故之它具有能在短时间内供加热物体内外同时均匀加温的特点。而且对环境不造成公害。微波炉在食品工业上的用途十分广泛,可烘干饼干,巧克力,麦乳精与奶粉等,也可
Microwave as an energy technology to research and application, or the last two decades, the so-called microwave is between the ultra-short wave and infrared electromagnetic waves. The general frequency of 30 to 300 gigahertz, the wavelength of one millimeter to one meter range of electromagnetic waves is called microwave. Modern microwave energy devices use magnetron to generate microwave energy. Its heating feature is to make the molecules of the object to be heated move at a staggering rate of more than 24 billion times through the action of the microwave energy so that the molecules A strong collision between the rapid friction and produce a lot of heat. Therefore, it has a short period of time for heating objects inside and outside at the same time heating characteristics. And does not cause environmental pollution. The use of microwave ovens in the food industry is very wide, can be dried biscuits, chocolate, wheat milk and milk powder, etc.
