Application of Drying Technology in China in Various Industries

On the one hand, China's degree of agricultural mechanization is not enough; on the other hand, it also shows that there is still a big gap in our concept of consumption. The drying of crops directly affects the quality of crops, such as "fine", it will not cause cracking and threshing, but the drying method and drying process problems. Different drying methods and drying processes also affect the taste and nutrition of the crop. It is believed that as China's process of fully pursuing a well-off society continues to accelerate, people’s consumption concepts have also undergone profound changes. Professor Pan said: "Yongkang's research on drying technology mainly refers to theoretical drying, drying process and equipment research." The focus of the theory of drying now is not the phenomenon of transfer outside the material, but the phenomenon of internal transport of the dried material. The type of material being dried, and the change in texture and transfer characteristics of the material during dehydration. Therefore, although much work has been done internationally, it is still not ideal and it still cannot solve the problem. Even today, the drying conditions are mainly determined by experiment and experience. At the same time, domestic and foreign scholars have conducted a lot of research on drying processes and equipment.

In China, more than 70 colleges and universities, research institutes and a large number of specialized in drying technology research. China's research and development in dry grain, dry fruit and vegetable dried biological materials and some new types of drying equipment have been at the forefront of the international level. Although China's drying equipment manufacturing enterprises are ordinary, weak R&D strength and low investment, there are also some Very good product development projects, such as self-cleaning rotating cylinders, closed loop organic fluid inert particle fluidized bed, large-scale spray fluidized bed granulation, 45 tons large-scale spray drying equipment, but unfortunately, most of the enterprise development technology is Confidentiality is usually not open for academic exchanges. According to Mujumdar, the former Soviet Union at least 200 dry and dry technical experts, before the 19th century, the world's leading position, but due to national conditions and language barriers affecting their integration into the international drying industry, today they did not see their published incisive papers, we should For the ring. In order to make China's drying technology fully catch up with countries with advanced international standards, there are many things to do, but one of the important factors in the academic and industrial circles is close. In this regard, we started earlier. The spray drying technology jointly developed with Dalian University of Science and Technology, the Chinese Academy of Forestry, and other universities and research institutes not only won the favor of the domestic market, but we ended up relying solely on imported spray drying machinery. The situation has also entered the international market. In this regard, in recent years, we have published more than 20 professors of academic papers in international and domestic journals, and translated and published his paper “The New Progress of the Principles and Equipment of Drying Processes” through the exchange of technical information; and Canada’s Energy Research Center. Drying of organic waste is carried out by extensive exchanges and cooperation with low-pressure spray drying developed jointly by the US State of Belarus, Kauf, Institute of Heat and Mass Transfer; and the Polish Technical University, we also conducted a number of cooperations, including technical exchanges. , cooperation and learning, etc.
