Microwave drying characteristics: 1, selective heating. Because water molecules absorb the microwave best, so most of the high water content, low moisture absorption of microwave power more than the parts. This is the selective heating characteristics, the use of this feature can be uniformly heated and evenly dry. 2, energy efficient. Microwave is a direct effect on the material, thus no additional heat loss, and the corresponding air furnace will not heat the container, so the high thermal efficiency, the production environment is also significantly improved compared with the far-infrared heating can save 30% . 3, time is short, and high efficiency. Microwave heating is to heat the heated object itself becomes the body, no heat transfer process. Microwaves penetrate from all directions inside and outside the object within the object in a very short period of time while heating up evenly, greatly reducing the drying time. 4, easy to control, advanced technology. Compared with conventional methods, equipment, means that the use; no thermal inertia, operating flexibility; microwave power adjustable, adjustable speeds. In microwave heating, drying, no water, no gas, high-tech is a safe and sound.
