[Study on correlation between relative density and kinematical viscosity of concentration for Yuxianling granules].
OBJECTIVE
To study the relation between relative density and kinematical viscosity of the concentration for Yuxianling granules.


METHODS
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.


RESULTS
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.
