crowave is a kind of electromagnetic wave whose frequency is between radio wave and far infrared ray. Its characteristic is high frequency and short wavelength. Its frequency and wavelength range are about 300 MHz to 300 kMz and 1~100 mm. Microwave technology is first applied in the fields of communication,
broadcasting and television.
It is found that microwave can cause thermal effect in use, and then the application research of microwave heating has begun worldwide. At present, the frequency of microwave heating is 915 MHz and 2450 MHz. Microwave drying originated in the 1940s. By the end of the 1960s, microwave energy had been used in heating, drying, insecticide, sterilization, medical and other industrial projects. The application of microwave drying technology in China began in the early 1970s. At present, microwave technology has been applied in light industry, food industry, chemical industry and agricultural products processing and other fields. This paper introduces the application of microwave heating and drying in wood processing.
