摘要(Abstract):

目的:研究愈痫灵颗粒水提浓缩液中相对密度与运动黏度的关系。方法:测定浓缩液的相对密度;利用酸式滴定管测定浓缩液的黏度与运动黏度,考察运动黏度与喷雾干燥及温度的关系,并对其进行数学模型的拟合。结果:运动黏度对喷雾干燥的影响大于相对密度;获得了运动黏度随温度的变化规律,从而为喷雾干燥提供适宜的进液温度。结论:为中药提取液浓缩与喷雾干燥提供一定的理论基础。
Objective: To study the relation between relative density and kinematical viscosity of the concentration for Yuxianling granules.Method: The relative density and kinematical viscosity by alkali burette of the concentration were investigated.The connection between kinematical viscosity and spray drying,also and temperature of the concentration was respected.In the meantime,different mathematical models were simulated.Result: Kinematical viscosity is susceptible than relative density to the effect for spray drying,and the mathematical model is also set up accordingly.The result can offer the proper inlet temperature and kinematical viscosity for spray drying.Conclusion: The method in the experiment is simple,practical and manipulate easily.The study will provide the basis for extracted solution of compression and spray drying.
