Third, the immediate goal

Clearly and practically, it is clear that the infrastructure of the microwave engineering itself must be improved. Through the specific projects of microwave application, the scientific research results will be gradually turned to industrialization. The prospects of the microwave application market are very promising. At present, there are several significant projects that can be carried out because we have mastered the core technologies and can quickly open up the market and achieve considerable economic benefits through hard work.

1, medical low-temperature microwave plasma sterilization, medical devices such as gastroscope, colonoscopy and plastic type medical devices can not be used for high-temperature disinfection, but chemical disinfection is easy to produce residues on the device, potentially harmful to people, disinfection time is not easy A cross-contagion of the virus has occurred. Medical cryogenic microwave plasma sterilization equipment can be used for low temperature or normal temperature sterilization in a short period of time. Domestically, it is still blank. It is used by a few developed countries in foreign countries, but the price is very expensive. This topic mainly uses technology: microwave technology, plasma discharge technology, vacuum technology, micro air flow control technology.

2, pump type microwave drying equipment: heat pump drying technology is a more advanced technology, zui is characterized by high efficiency, once (KWH) can dehydrate 3 to 5 kg, far lower than conventional steam drying has many advantages, but the energy consumption is greater At one time, the electric dehydration was only 0.5 kg. If the two technologies are combined, there will be major innovations in the drying process. This equipment is truly efficient, environmentally friendly and adaptable. It can replace many traditional drying equipment and enter various industries. The heat pump type microwave drying has been successfully reported in experiments, and developed countries have just prepared to vigorously develop and promote them.

3, wave chemical test equipment and microwave chemical engineering: the application of microwave in the field of chemistry has become a hot topic today, not only involves drying, heating, but also development to catalysis, hydrolysis, digestion, incineration, desulfurization, petroleum demulsification, dewaxing, thawing , material modification, ceramic sintering, vapor deposition, diamond film, rubber vulcanization. The technical transformation of the laboratory requires engineering and technical strength. At present, in terms of microwave engineering technology, the designers of our unit have accumulated a lot of experience, and it is a strong research and development team for microwave application engineering in China. For example, after the rubber vulcanization retrofit design last year, the performance of the whole machine was advanced to the advanced level in foreign countries. 0 lines were sold in less than one year, sales reached 1000, and foreign manufacturers' microwave rubber vulcanization equipment was pushed into Guchi in domestic sales.

4, microwave extraction equipment and complete sets of equipment: Chinese medicine pharmaceutical modern significance does not need to talk about, the market lacks microwave extraction complete sets of equipment, from the introduction of microwave extraction tanks last year, until now only one year, we have sold into 10 equipment (but not Complete set), market feedback information analysis, large, medium and small sets of micro-extraction equipment demand is huge, microwave extraction is superior to supercritical extraction, ultrasonic extraction, chemical extraction, and more in line with our national conditions, the heat has the corresponding supporting technology, There will be huge room for market opening.

Fourth, the conclusion

We have accumulated a wealth of experience in the field of microwave engineering, and some aspects of ling's domestic counterparts and microwave application technology are also in the forefront of international ling. Over the years, it has helped a large number of research work in various industries, universities and research institutes across the country, involving a wide range of disciplines and industries. This is a large intangible asset. Establish a provincial or *microwave engineering research center, and with a certain amount of start-up funds, you can push the microwave application project into the economies of scale within a short period of time. In many developed countries, the microwave application engineering market has hundreds of millions of Americans every year. As a developing country, the prospects are very promising. The price of equipment for foreign microwave application market is 7-8 times higher than that of China. As long as we do our internal work, it is not a distant matter for microwave equipment to go abroad.
