Technology research should be vigorously developed for drying equipment in China

The application of drying equipment in petrochemical enterprises is very common It serves for petrochemical enterprises and is greatly influenced by the industry economy Therefore, the research of drying technology is very important For drying technology, there are three goals recognized by scholars, that is, to ensure product quality in drying operation; to avoid environmental pollution in drying operation; and to study energy saving in drying Chinese scholars have made a lot of achievements in the research of drying technology Liu Dengying, researcher of Institute of Engineering Physics, Chinese Academy of Sciences, has studied the super rapid heat and mass transfer under the action of micro time scale and high heat flux density The existence of non Fourier heat conduction (non-equilibrium) effect has been verified by experiments The influence trend of non Fourier heat effect and non Fick diffusion effect on the drying process has been put forward, and the drying and colliding flow of multi-layer fluidized bed have also been influenced The unsteady drying process in the dryer was studied comprehensively In addition, the vertical, half ring and their combined impinging stream drying were studied theoretically and experimentally Wang Xizhong, Professor of drying Engineering Research Laboratory of Dalian University of Technology, is spray drying in China One of the experts, he and colleagues professor Wang Baohe and Professor Yu Caiyuan have carried out extensive research on China's spray drying industrial installation The Zui large device has been designed to reach 10000t annually Rice noodles and microencapsulated phospholipid and lycopene technology, electrostatic atomization technology, supercritical drying and nano powder drying are all located in the first place of domestic Ling Professor Xu Chenghai of Northeast University is a freeze-drying expert in China In recent years, he has successfully developed continuous vacuum drying equipment and continuous vacuum freeze-drying equipment, which can freeze-drying live bacteria, live toxins, skin, bone, cornea and other biological products It is of great significance in medicine In the research of new microwave drying technology, Dr Dong tieyou of Henan University of science and technology proposed a theoretical method to determine the energy distribution in the microwave drying room according to the radiation energy distribution pattern of the antenna Through the research on the energy reflection characteristics of the microwave drying chamber under the typical load conditions and the microwave drying technology of rice, the data with important reference value for practical application are obtained: the processing technology and basic technological parameters of Chinese cuisine food are creatively studied by using the microwave freeze drying technology Drying equipment In the direction of technology, the industry should strengthen the research on automation, manufacturing technology and material appearance design, learn foreign advanced technology, let enterprises directly cooperate with these universities and scientific research institutions in various forms, let enterprises become the main body of technological innovation, make China's drying equipment industry bigger and stronger, and strive to occupy an important position on the international stage.
