为开发利用经液压压榨制油后的牡丹籽粕,采用超微粉碎方法将其制备成粒径小于78μm超微粉,研究其最佳工艺条件和营养成分变化.结果表明,超微粉碎最佳工艺条件是进料粒径为40目,主粉碎机频率为35 Hz,旋风分离机频率为25 Hz,粉碎时间为45 min.在该工艺条件下,出料袋中超微粉产率达42.6%,粉末粒径D90为54.598μm,其主要营养成分保留完好.%For the development and utilization of peony seed meal after the hydraulic press to make oil, the ul-trafine powder of particle size of less than 78μm was prepared by using ultrafine grinding, its optimum techno-logical condition and the change of nutrient component were studied. The results showed that the optimum con-dition of ultrafine grinding was the feed particle size of 40 mesh, host frequency of 35 Hz, cyclone separator fre-quency of 25 Hz, and grinding time of 45 min. Under the optimum conditions, the yield was up to 42.6%and size D90 was 54.598μm of ultrafine powder in the discharging bag, and its main nutrient components were well preserved.
