摘要：为了获得高品质的玫瑰花粉体产品,首先对玫瑰花鲜花进行真空冷冻干燥处理,然后采用双向旋转球磨机对玫瑰花进行超细粉碎,研究在粉碎过程中筒体及搅拌器转速、球料质量比、研磨时间等工艺参数对玫瑰花粉体产品粒度的影响。结果表明:球磨法制备玫瑰花粉体的最佳条件是筒体转速为120 r/min,搅拌器转速为80 r/min,球料质量比为10,研磨时间为120 min;制备的玫瑰花粉体的中位粒径d₅₀为6.1μm,并很好地保留玫瑰花的芳香。

Abstract： To obtain high quality rose powders， the vacuum freeze dryer was used to dry the fresh rose， then the twin-rolling mill was used to grind the rose. In the process of grinding， the effects of process parameters on the size of superfine rose powders were discussed， such as the speed of barrel and agitator， the mass ratio of grinding-balls to materials， the grinding time， which influence the particle size of the rose powders. As the results show， the optimum conditions used are that the barrel speed is 120 r/min， the agitator speed is 80 r/min， the mass ratio of grinding-ball to materials is 10:1， the grinding time is 120 min. The mid-size of the obtained rose powders is 6.1 μm. These powders remaine the fragrance of rose well.
