How to develop dry machinery in China

When talking about market issues, the three experts agreed that the application of drying technology in China is now limited to the chemical industry but is widespread in all walks of life, and with the continuous development and advancement of science and technology, the application of drying technology The field will be further broadened and the potential market is very large. Professor Cao Chongwen said: 'In the case of agricultural products, the drying equipment for agricultural products owned by Japan is roughly 1.5 to 1.7 million units, while there are only 20,000 units in China.

On the one hand, it shows that the degree of agricultural mechanization in China is far from enough; on the other hand, it shows that there is still a big gap in our consumption philosophy. The drying of crops directly affects the quality of crops. For example, the 'burst' of rice, cracks, etc. are not caused by threshing, but are problems of drying methods and drying processes. Different drying methods and drying processes will also affect the taste and nutrients of crops. It is believed that as China's comprehensive and prosperous process continues to accelerate, people's consumption philosophy will also undergo profound changes. Professor Pan Yongkang said: 'The study of drying technology mainly refers to the study of drying theory, drying process and drying equipment.

The focus of today's drying theory research is not the transfer phenomenon outside the material but the transfer phenomenon inside the material in the drying process. There are many types of materials to be dried, and the texture and transfer characteristics of the materials are also changing during the dehydration process. Therefore, although a lot of work has been done in the international community, it is still not ideal and still cannot solve the problem. So far, still rely mainly on experiments and experience to determine drying conditions. At the same time, domestic and foreign scholars have done a lot of research on drying processes and equipment.

In China, there are more than 70 institutions of higher learning, research institutes and a large number of experts engaged in research on drying technology. In China, some researches on the drying of cereals, the drying of biological materials, the drying of vegetables and fruits, and some new drying equipments have been at the forefront of the international level. Although the drying equipment manufacturing enterprises in China generally have weak research and development, they have not invested much. But there are also some good product development projects, such as self-cleaning rotary cylinders, closed-cycle organic superheated steamy particle fluidized bed, large-scale spray fluidized granulation, 45 tons of large-scale spray drying equipment, etc., but unfortunately the enterprise Most of the technologies developed are in a state of confidentiality and are usually not open to academic exchanges.

According to MUJUMDAR, there are at least 200 international-level drying experts in the former Soviet Union. Drying technology was a world leader in the 1980s. However, due to national conditions and language barriers, they have become more and more integrated into the international dry world. To the brilliant papers they published, we should take this as a warning.

In order to make China's drying technology fully catch up with the level of international advanced countries, there are many things to be done, but the close integration of academia and industry is one of the most important factors.

Zhou Caijun, a well-known expert in the manufacture of spray drying equipment in China and the director of Wuxi Linzhou Drying Equipment Factory, also talked about his own views. He said: 'From the perspective of domestic drying equipment manufacturers, there are not only technical innovation problems, but also one. The problem of upgrading on the upper level and the problem of superior competition.

In this respect, we started early, and jointly developed research and research on spray drying technology with universities and research institutes such as Dalian University of Technology and Chinese Academy of Forestry, which not only won the favor of the domestic market, but also ended the past relying on imports of spray drying machinery in China. The situation, but also into the international market 'Shandong Academy of Sciences Energy Research Institute deputy director, researcher, Shandong Tianli company chairman and general manager Shi Yongchun said in his speech: 'Not long ago, the international dry meeting held in Beijing from In terms of communication, there is still a certain gap between China's dry technology research and development and the world's advanced level, especially in basic research. Therefore, no matter from the perspective of academic research or from the perspective of enterprises, how to further narrow our relationship with On the issue of the gap between the international advanced levels, Tianli has unshirkable responsibilities and obligations.

In recent years, we have published more than 20 academic papers both at home and abroad, and have published and translated "The Principles and Equipment of Drying Process and New Progress" with Professor MUJUMDAR through technical information exchange; and CANMET Energy Research Center of Canada Extensive exchanges and cooperation in the drying of organic waste; the medium and low pressure spray dryer was jointly developed with the Rekov Institute of Heat and Mass Transfer of the National Academy of Sciences of Belarus; and the University of Lodz Technical University in Poland has also carried out various aspects. Cooperation, including technical exchanges, collaborative research, etc.

The 'spray fluidized bed granulation technology' that we jointly researched and developed has been included in the cooperation project between the two governments. China has joined the WTO and is working hard to research and develop technologies and products with independent intellectual property rights. At present, the two doctors we have trained from home and abroad have been enriched to Tianli Company. In the future, we will further enrich our technical strength and increase development efforts.

Everyone agrees that China must develop from a dry country to a dry and strong country. It must further strengthen basic theoretical research, and lay a solid foundation for applied research and application development. Technically, it must strengthen the degree of automation, testing technology, manufacturing process and material material design. Other aspects of research. In terms of application development, we must pay attention to international exchanges and cooperation, but also focus on the protection of intellectual property rights; we must pay attention to the development of new technologies and new application areas, as well as innovation and innovation in traditional and traditional applications.

As a manufacturing enterprise, we must work hard on management innovation and technological innovation, work hard on the upgrade of products, adjust product structure according to the requirements of high quality, low energy consumption and environmental protection, foster competitive advantage, promote honest service and promote enterprise development.
