微波烘干机依赖于微波加热 Microwave dryer depends on microwave heating

微波烘干机依赖于微波加热。微波烘干机原理完全不同于传统的加热方法（传导、对流、辐射）。当微波照射到含水物料时，由于水分子是极性分子，极性分子排列从杂乱无章非极性状态变成有序排列。当外电场方向反复变动时，极性分子相应随之反复转换，频繁地摆动，在摆动过程中，造成分子间类似摩擦作用而产生大量热量，物料的温度也随之升高。微波烘干机就是利用介电损耗原理将微波能转化成为物料加热所需要的热能[1]，物料吸收热量与其物料电介质的损耗因子成正比。由于水（或其它溶剂）的电介质损耗因子比其他物质大得多，所以水（或其它溶剂）分子优先吸收微波能，水分子由物料内部向表面移动，继续吸收微波能，水分变成水蒸汽而被排走，从而迅速完成干燥的目的。而其过程时间短，方可达到您想要的结果。

Dryer relies microwaves microwave heating. Principle of microwave drying machine is completely different from the traditional methods of heating (conduction, convection, radiation). When you microwave exposure to materials containing water, because water molecules are polar molecules, polar molecules arranged from disorganized non-polar State becomes orderly arrangement. When an external electric field direction change repeatedly, polar molecules then move up and down frequently, swing, swinging at the process, had a similar friction between molecules and produces a lot of heat, the material temperature is elevated. Microwave drying principle is the use of dielectric loss of microwave energy into the material needed to heat thermal energy [1], the material absorbs heat and its material is proportional to the dielectric loss factor. Due to the water (or other solvents) for dielectric loss factor of much larger than other substances, so the water (or other solvents) molecular absorption microwave energy priority, moving water molecules from within the material to the surface and continue to absorb microwave energy, by the discharge of water into steam and go and can quickly complete the purpose of drying.
