微波是指频率在300兆赫兹到300千兆赫兹的电磁波。被加热介质物料中的水分子是极性分子。它在快速变化的高频电磁场作用下，其极性取向将随着外电场的变化而变化，造成分子的运动和相互摩擦效应。此时微波场的场能转化为介质内的热能，使物料温度升高，产生热化和膨化等一系列物化过程而达到微波加热干燥的目的。

微波干燥是一种高效、节能、稳定、可靠、设备简单、操作方便和新技术。微波干燥机的特点是设备连续生产，只需要用电，不需要其它能源，能快速的将物料干燥，设备占地小，无污染，操作简单；不需要预热也没有在停机后还有能源损耗。人工少，产品质量高。设备*化程度高，是别的设备无法替代的*产品。

Microwave dryer

The purpose of microwave dryer is:

Mainly used for paste food, powder food, granular food, agricultural products, and other products that need to be dried by microwave drying sterilization; microwave dryer can be designed and manufactured according to the different needs of different products.


Heating principle of microwave dryer


Microwave refers to electromagnetic waves with frequencies ranging from 300 MHz to 300000 trillion Hz. The water molecules in the heated medium are polar molecules. Under the fast changing high frequency electromagnetic field, its polar orientation will change with the change of external electric field, resulting in the movement of molecules and mutual friction effect. At this time, the field energy of microwave field can be transformed into heat energy in the medium, which makes the material temperature rise, and produces a series of physical and chemical processes, such as heating and expansion, to achieve the purpose of microwave heating and drying.
