Microwave equipment is recommended for drying single crystal silicon. As is shown in experimental research and practice comparison, microwave drying of single crystal silicon performs better mainly in uniform drying, high drying speed and short working time.

Microwave radiation penetrates the single crystal silicon to generate thermal effect, so that the single crystal silicon itself becomes a heating element. The temperature rises, and the water vaporization inside is discharged by the drainage system to achieve the purpose of drying.

Single crystal silicon microwave drying equipment has many advantages, mainly in the following aspects:

1. The single crystal silicon microwave drying equipment adopts PLC automatic control, automatic temperature control system, video monitoring system, transmission belt automatic correction system, transmission frequency conversion speed control system, etc., with sensitive temperature control and reliable performance. Real-time monitoring of the drying process, one-button setting of the working state of the device, automatic operation, simple operation and low labor intensity.

2. Easy to control and advanced technology. Compared with the conventional method, the microwave drying equipment is ready to use, instantly off and on, without thermal inertia, and the operation is flexible and convenient. The microwave power and the transmission speed are adjustable. It can automatically turn off the power and protect equipment and products under abnormal environmental conditions. In the microwave drying process, no waste water and waste gas are produced, which is a safe and harmless high-tech.

3. Selective heating. Since the water molecules absorbed by the microwave ray, the portion with a high water content absorbs more microwave power than the portion with lower water content. By utilizing this feature, uniform heating and drying can be achieved which effectively avoiding the phenomenon that the internal and external drying effects are inconsistent. Microwave drying can increase the drying temperature.
