When it comes to market issues, the application of drying technology in China is by no means confined to the chemical industry but it is widespread across industries. With the continuous development and progress of science and technology, the application of drying technology will be further broadened. The market is very large. Taking agricultural products as an example, the drying equipment for agricultural products owned by Japan is roughly 1.5 to 1.7 million units, compared with only 20,000 units in China. The focus of the theory of drying today is not the phenomenon of the transfer outside the material but the phenomenon of the internal transfer of the material during the drying process. A wide variety of materials are being dried, and the texture and transfer characteristics of the materials are changing during the dehydration process. Therefore, although a lot of work has been done on the international front, it is still not ideal and it still cannot solve the problem. As of today, the dry conditions are still largely determined by experimentation and experience. At the same time, domestic and foreign scholars have done a lot of research on drying processes and equipment. There are more than 70 colleges and universities, research institutes and a large number of experts in drying technology research in our country. In China, some research and development of grain drying, drying of biological materials, drying of vegetables and fruits, and some new drying equipment have been at the forefront of the international level. Although China’s drying equipment manufacturers generally have weaker research and development and have invested less, But there are also some very good product development projects, such as self-cleaning rotary cylinders, closed-cycle organic superheated steam helium particle fluidized bed, large-scale spray fluidized granulation, 45 tons of large-scale spray drying equipment, etc., but unfortunately, Most of the technology developed is in a state of confidentiality and usually does not openly engage in academic exchanges. According to MUJUMDAR, there are at least 200 international-level drying experts in the former Soviet Union. Drying technology was the world leader before the 1980s, but due to national conditions and language barriers that have affected their integration into the international drying industry, they are rarely seen today. To the brilliant papers they published, we should take warnings in this regard. In order for China's drying technology to catch up with the international advanced countries, there are many things to do, but the close integration between the academic community and the industry is one of the most important factors. In this regard, we started earlier. We have jointly developed and researched spray drying technology with universities and scientific research institutes such as Dalian University of Technology and China Academy of Forestry. We not only won the favor of the domestic market, but ended our country's past relying on imports of spray drying machinery. The situation also broke into the international market. In this regard, in recent years, we have published more than twenty academic papers at home and abroad, and we have translated and published his book “Principles and Equipment and Processes of Drying Processes†through the exchange of technical information with Prof. MUJUMDAR; and Canadian CANMET Energy Research Center. In the aspect of drying of organic waste, extensive exchanges and cooperation were carried out; a medium-low pressure spray dryer was jointly developed with the Reckov Institute of Heat and Mass Transfer of the Belarusian National Academy of Sciences; and the University of Technology in Lodz, Poland, also carried out various aspects. Cooperation, including technical exchanges, cooperative research, etc. The "spray fluidized bed granulation technology" that we jointly researched and developed has been included in the cooperation projects between the two governments. China has already joined the WTO and must work hard to research and develop technologies and products with independent intellectual property rights. At present, the two doctors we have cultivated both at home and abroad have been enriched to Tianli Company. In the future, we must further enrich our technical strength and increase our development efforts. Everyone unanimously believes that China must develop from a large dry country to a dry and strong country, and must further strengthen basic theoretical research and lay a solid foundation for applied research and application development. Technically, it must strengthen automation, testing techniques, manufacturing processes, and materials and materials. Other aspects of research. In terms of application development, it is necessary to focus on international exchanges and cooperation, but also on the protection of intellectual property rights; it is necessary to pay attention to the development of new technologies and new applications, but also to focus on innovation and innovation in traditional processes and traditional applications. As a manufacturing company, we must work hard on management innovation and technological innovation, work hard on product upgrades, adjust the product structure in accordance with the requirements of high quality, low energy consumption, and environmental protection, cultivate competitive advantages, promote honest services, and promote the development of enterprises.
On the one hand, it shows that the degree of agricultural mechanization in our country is still far from enough; on the other hand, it also shows that there are still big gaps in our consumption philosophy. The drying of crops directly affects the quality of crops. For example, the "burst" and cracks of rice 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 nutritional content of crops. It is believed that as China's process of fully pursuing a well-off society continues to accelerate, people's consumption concepts will also undergo profound changes. 'Prof. Pan Yongkang said:' Drying technology research mainly refers to the drying theory, drying process and drying equipment research.
