Structural Optimization and Moisture Content Simulation of Tea Residue Dual Axis Stirring Dryer
摘要
Abstract
The most important step of tea residue reuse is drying.In order to optimize the drying process of tea residue dual-axis stirring dryer,Euler-Euler multiphase flow model and component transport model of Fluent software was used to simulate.The results of structure optimization and water content analysis showed that:adding the diversion grille could greatly improve the uniformity and average temperature of the flow field inside the dryer.The change trend of the average temperature inside the dryer increased first and then decreased with the increase of the angle of the diversion grille,and increased first and then decreased with the increase of the number of grilles.The best effect was achieved when 5 grilles were arranged with a spacing of 1 030 mm,and the average internal temperature of the dryer was 429.23℃.When the hot air temperature was 500℃and the spindle speed was 300 r·min-1,the water content of the material at the discharge port of the dryer was the lowest,which was 12.91%.This simulation result provided technical parameters for the design of large double-shaft mixing dryer.关键词
