New Findings in Materials Science and Engineering Described from National Taipei University of Technology

June 25, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Fresh data on Materials Science and Engineering are presented in a new report. According to news reporting out of Taipei, Taiwan, by VerticalNews editors, research stated, "Vacuum freeze-drying technology is applicable to the process of high heat-sensitive products. Due to the long drying period and extremely low processing temperature and pressure, the uniform and efficiency of heat transfer fluid temperature in shelf are critical for product quality."

Our news journalists obtained a quote from the research from the National Taipei University of Technology, "Therefore, in this study, the commercial computer fluid dynamics (CFD) software, FLUENT, was utilized for three-dimension numerical simulation of the shelf vacuum freeze- drying process. The influences of different inlet and outlet positions for shelves on the uniformity of the flow rate and temperature were discussed. Moreover, it explored the impacts on the temperature gradient of shelves after heat exchange of different flow rates and low temperature materials. In order to reduce the developing time and optimize the design, the various secondary refrigerants in different plies of shelves were investigated."

According to the news editors, the research concluded: "According to the effect of heat exchange between different flow rates and low temperature layermaterial shelves on the temperature gradient of shelves surface, the minimum temperature gradient was 20 L/min, and the maximum was 2.5 L/min."
