Liu Dengwei, researcher of the Institute of Engineering Physics, Chinese Academy of Sciences, studied ultra-rapid heat and mass transfer at the micro-time scale and high heat flux, and verified the existence of non-Fourier heat conduction (non-equilibrium) effects. The influence of the thermal effect of the inner leaf and the non-Fick diffusion effect on the drying process, and a comprehensive study of the non-steady state drying process in the multi-layer fluidized bed drying and the colliding flow dryer. In addition, theoretical and experimental investigations have been carried out on the drying of collided flow in vertical and semi-rings and their combinations.
Professor Wang Xizhong of the Drying Engineering Research Department of Dalian University of Technology is one of the famous spray drying experts in China. He and his colleagues Professor Wang Baohe and Professor Yu Caiyuan conducted extensive research on spray drying industrial installations in China and designed the largest installation. Years can reach 10000t. Research on microencapsulation technology of phospholipid oil and lycopene, electrostatic atomization technology, supercritical drying, and nano powder drying are all in the leading position in China.
Prof. Xu Chenghai of Northeastern University is a domestic freeze-drying expert. In recent years, he has developed continuous vacuum drying equipment and continuous vacuum freeze-drying equipment. It can freeze-dried living bacteria, live poison, skin, bone, cornea and other biological products. Significance.
Dr. Dong Tieyou from Henan University of Science and Technology, for the first time, proposed the energy distribution in the microwave dry room in terms of new microwave drying technology. The theoretical method should be determined based on the distribution of the radiation energy of the antenna. Through the research on the energy reflection characteristics of microwave dry room under typical loading conditions and microwave dry technology issues of rice, we obtained data with important reference value for practical applications: Using microwave freeze-drying technology, creatively studied the Chinese food Processing technology and basic process parameters.
The drying equipment industry should strengthen research in automation, manufacturing processes, and materials and materials design in the technical direction, learn advanced foreign technologies, and let companies directly associate with these universities and research institutes in various forms to make enterprises become technological innovations. The main body will make China's drying equipment industry bigger and stronger, and strive to occupy an important position in the international arena.
Drying technology research is very important for the development of the drying industry
For the drying technology, there are three goals that are recognized by scholars. That is, the drying operation should ensure the product quality; the drying operation does not cause pollution to the environment; and the dry energy-saving research. Chinese scholars have made a lot of achievements in the research of drying technology.
