Objective:
To study the technology of ultra-fine pulverization of Flos Caryophylli.
Methods:
A single factor experiment was used to choose the method of ultra-fine pulverization for Flos Caryophylli. An orthogonal test was used to optimize the technology of ultra-fine aeropulverization of Flos Caryophylli. The preliminary powder fineness, the quantities and the types of accessories were optimized by the test, according to the indices such as ultra-fine powder yield, the average particle size and the powder flowbility.
Results:
The super-fine powder made by the method of aeropulverization was the best, but the shape and properties were not stable. In the orthogonal test, factor A (the preliminary powder fineness) and B (the types of accessories) had little effect on all indices; Factor C (the ratio of accessories) had significant effect on the powder flowbility. The best technology was A1 B3 C3.
Conclusion:
In this study, the obtained powder has good flowbility, average size and quality stability, so it can be promoted as the technology of ultra-fine pulverization condition for Flos Caryophylli.
